1.2 INTRODUCTION (See Figures 1-1 and 1-2)
1.2.1 General
The MICROLOK PLUS Vital and Non-Vital Control Package is a multi-purpose, microprocessor-based device designed for use in both vital and/or non-vital railroad control systems. It is typically used for smaller applications, such as a single end-of-siding, that do not require the large input/output capabilities of seperate vital and non-vital controllers. The device can be configured with a vital control section only, or with vital and non-vital control sections. (A non-vital-only configuration is also possible, but not typical.)
In a typical single end-of-siding application, both sections are utilized. The vital section controls the interlocking logic, manages switch machines, signals and track circuits in the control area; while the non-vital section provides an interface point for a local control panel, processes CTC office commands, and transmits indications from the vital section. Another typical end-of-siding configuration could consist of the vital section only, with code system inputs and outputs processed within the vital section (no local control panel).
The MICROLOK PLUS system is derived from the US&S MICROLOK Vital Interlocking Control System and the GENISYS Non-Vital Logic Emulator. It uses the same plug-in printed circuit boards (logic and interface), the same Executive software, and the same application logic compilers as the MICROLOK and GENISYS systems.
1.2.2 Vital Section Basic Functions
The vital section of MICROLOK PLUS unit is designed specifically for railroad vital interlocking applications. Its basic function is to process various inputs according to a program designed by the application engineer, and create the appropriate outputs. This program takes inputs, performs logic and timing functions on those inputs and produces an output. The program operates in the same manner as a conventional vital relay logic system.
Inputs and outputs consist of "local" and "serial". Local inputs typically include track circuit occupancy, state of switch machine point contacts, state of signal relay or mechanism contacts, and traffic and line circuits. Local outputs eventually interface to control signal mechanism drives, signal lamp drives, switch control contactors and traffic and line control circuits. Serial inputs and outputs typically carry vital and non-vital control and indication messages between the MICROLOK PLUS system and other vital and non-vital controllers, or between the vital and non-vital sections of the unit.
Local input options include standard off/on (bit 0/1) voltage inputs, or bi-polar voltage inputs (bit O or 1 for each polarity). Two voltage input ranges are available with these options: 12 or 24 Vdc (nominal). Local vital output options include standard (single pole) relay drive, or bi-polar relay drive. Lamp-compatible outputs are available to drive 18, 25 or 36 watt, 10 volt signal lamps.

1.2.3 Non-Vital Section Basic Functions
The non-vital section of MICROLOK PLUS unit can perform the functions of various non-vital relay logic and digital logic systems, according to a program designed by the application engineer. This program takes inputs, performs logic and timing functions on those inputs and produces an output. The program operates in the same manner as a conventional non-vital relay logic system.
Inputs and outputs consist of •1ocal" and "serial•. Local inputs include all non-vital relay or switch contact signals, such as from a local control panel or code system field circuits. Local output options include internally strobed or non-strobed delivery and constant state at power off. Serial inputs and outputs typically carry non-vital control and indication messages between the MICROLOK PLUS system and other vital and non-vital controllers, or between the non-vital and vital sections of the unit.
1.2.4 Serial Data Systems (See Figure 1-2)
1.2.4.1 Vital Section
The MICROLOK PLUS unit is equipped with •ports• for serially communicated data. The vital section includes a Master port that enables the device to serve as the managing unit of a vital Master/Satellite system. Up to 16 Satellite units can be controlled from this port. The Satellite units for such a system might include additional MICROLOK PLUS or MICROLOK units, or a combination of both. The vital Satellite port enables the unit to function as a Satellite to another Master unit (MICROLOK PLUS or MICROLOK).
A 20 mA current loop option is also available for vital or non-vital serial communications between the MICROLOK PLUS system and related systems installed in different wayside houses. This option is designed for maximum noise immunity and may be operated over a maximum distance of 10,000 feet (total loop length). A separate current Loop Adapter Panel, not included with the basic MICROLOK PLUS unit, is required for this option (refer to section 1.4.2).
When required by the application, the vital section of the MICROLOK PLUS unit can incorporate a non-vital port for communications with a non-vital controller such as the US&S GENISYS system or the unit's own non-vital section. This port is typically used when the external GENISYS unit or MICROLOK PLUS non-vital section is used as the field unit in an office/field code system, or the interface to a local control panel. In this configuration, the non-vital controller serves as the Master unit and the MICROLOK PLUS vital section as a Satellite to that Master.
Vital serial link communications are formatted to EIA RS-423 standards, and aerated to operate under the RS-232C standards. This enables the MICROLOK PLUS vital serial ports to be interfaced to an EIA-compatible modem for remote communications.

1.2.4.2 Non-Vital Section
The non-vital section of MICROLOK PLUS incorporates a Master port that enables the device to serve as the managing unit of a non-vital Master/Satellite system. Up to 255 Satellite units can be controlled from this port, although the practical upper limit is about 40 to 50 units. The Satellite units for such a system might include additional MICROLOK PLUS or GENISYS units, or a combination of both. The non-vital Satellite port enables the unit to function as a Satellite to another Master unit. The Master unit can include another MICROLOK PLUS unit (non-vital section), a GENISYS system or an office mainframe or microcomputer.
When the application requires a serial link between the non-vital and vital sections of the MICROLOK PLUS unit, the non-vital Master port is used for this purpose, while the Satellite is used for external communications.
Non-vital serial link communications are formatted to EIA RS-423 standards, and aerated to operate under the RS-232C standards. This enables the MICROLOK PLUS non-vital vital serial ports to be interfaced to an EIA-compatible modem for remote communications.
1.2.5 Executive and Application Software (See Figure 1-3)
Each section (vital and non-vital) of the MICROLOK PLUS unit incorporates its own, independent Application and Executive software. These are contained in EPROM chips on the logic boards of the respective sections.
1.2.5.1 Application
The Application software or logic in each section is developed for the specific installation, either by US&S or the customer. The source program is written and "compiled" on a computer, using a language that enables the system logic to be expressed in terms familiar to the railroad engineer. The finished program is converted into a form that can be entered or "burned" into the EPROM chips.
The MICROLOK PLUS vital application logic can be developed using the optional MICROLOK Development System (M.D.S.), which consists of a personal computer, EPROM programmer, EPROM eraser, and software program disks. This system allows the user to conduct all phases of application program development, including compilation on a personal computer, debugging, and final checking (simulation) and programming into the vital application logic EPROMs.
The non-vital application logic can be developed using the optional GENISYS Development System (G.D.S.). This system provides the same program development, testing and EPROM-loading features as the M.n.s., and uses the same programming and loading equipment. However, the G.D.S. uses different development software for its non-vital logic function.

1.2.5.2 Executive
The executive software of the vital and non-vital sections of MICROLOK PLUS are are common to all units.
The vital section Executive software contains routines designed to (a) verify the states of vital inputs and outputs, (b) insure that all vital outputs are fully controllable, and (c) remove power to vital outputs in all cases where a system failure has occurred. Vital assurance is applied to local inputs and outputs, and to serial communications with other external systems. The Executive software also performs input, internal and output logic operations defined in the vital application logic, as well as diagnostic routines at different operational levels.
The non-vital section Executive software performs input, internal and output logic operations defined in the non-vital application logic.
6500, p. 1-7
1.2.6 Power Requirements and Applications
All configurations of the MICROLOK PLUS unit require a 24 Vdc (nominal) external power source. This power is regulated and converted by the Power Supply Converter Drawer to provide operating power for the vital and/or non-vital board electronics. The converter is simultaneously capable of powering two or three transmitter and receiver boards in a RFL type modem (remote serial link). This arrangement eliminates the need for a separate power supply converter for the modem.
When the MICROLOK PLUS system is interfaced to vital relay and lamp drive circuits, a separate 12 Vdc (nominal) power source is required. This source provides power for all Relay Driver and DC Lamp Driver PCB outputs. The 12 Vdc is supplied through the Vital cut-Off Relay to the vital input/output section of the cardfile.
When the MICROLOK PLUS system is interfaced to non-vital relay-output circuits, a separate 12 Vdc (nominal) power source is required. This power is carried through the relay contacts of the relay-output boards to relay coils of the external circuits.
1.3 HARDWARE DESCRIPTION
1.3.1 Cardfile
The MICROLOK PLUS package is housed in a single PCB cardfile (17 slots) with a combination hinged and removable front cover. Circuit board installation options and LED configurations are shown on a label attached to the inside of the cover. The cardfile is typically mounted in a standard 19 inch equipment rack, but may also be shelf mounted. The unit incorporates a slide-out drawer containing the unit's power supply converter. (No external power supply panel or plug-in converter board is required.) Two strain relief bars (movable) are also provided for serial and local I/0 cabling.
All of the MICROLOK PLUS PCBs plug into a common, printed circuit motherboard permanantly attached to the rear of the cardfile. The motherboard incorporates a connnon power bus that delivers operating power to all boards. However, the vital and non-vital motherboard data buses are separate.
As viewed from the rear of the cardfile, the four right-hand MICROLOK PLUS boards (vital logic) plug into both the bottom and top motherboard connectors. The upper or "A" connectors translate three of these four boards to 37 and 25-pin, "D" style connectors on the back or the motherboard. These serve as the vital and non-vital serial data ports for the vital section of the MICROLOK PLUS unit.
The "A" connector edges of the remaining boards project through slots along the top of the cardfile backplane. These slots allow attachment of 44-way PCB edge connectors for vital and non-vital local I/0 cabling, and for the serial link cable to the non-vital logic board.
The MICROLOK PLUS motherboard contains two Faston terminals ("RLY (+)" and RLY (-)") near the "D" connectors. Wiring to these terminals is connected to an external relay that serves as the system's vital cut-off relay, or VCOR.

2.4 POWER AND GROUND CIRCUITS
2.4.1 Power Sources
The MICROLOK PLUS system requires a single 24 Vdc source for operating power. Basic power specifications are the same as those for the MICROLOK system. For power input specifications, refer to:
S~j&t Cross Reference
Power source Specifications SM-6400B, section 2.4.1, page 2-2
NOTES
The input voltage range for the MICROLOK PLUS power supply converter is 19.8 to 32.4 Vdc, 24 Vdc nominal.
SM-6400B, section 2.4.1, page 2-2: The vital I/0 power requirements described in this section are applicable to the vital section of the MICROLOK PLUS unit.
When the non-vital section of MICROLOK PLUS is interfaced to local relay I/0 circuits, a separate 12 Vdc power source is required to energize individual inputs and outputs. If the vital section includes local relay and/or lamp driver outputs, the 12 Vdc power bus for these outputs can also be used to power the non-vital relay circuits. Make certain to wire the non-vital relay load according to Figure 2-1 of SM-6400B (as "OTHER LOAD").
2.4.2 Wiring and Surge/Noise Protection
Wiring and surge/noise recommendations for the MICROLOK PLUS unit are the same as those for the MICROLOK system. For these recommendations, refer to:
Subject
Wiring and Surge/Noise Protection
Cross Reference
SM-6400B, section 2.4.2, pages 2-3 through 2-5
NOTES
Section 2.4.2.2, part c, Note 3: The MICROLOK PLUS 24 Vdc power input does not require a HI-Q filtering capacitor.
Figure 2-1 on the following page is a typical power input wiring schematic for the complete MICROLOK PLUS system. Refer to this figure in place of Figure 2-2 of the MICROLOK manual SM-6400B.
6500, p. 2-2
2.4.3 Equipment Grounding (See Figure 2-2)
2.4.3.1 Rack and Cardfile Grounding
When the MICROLOK PLUS unit is installed in an equipment rack (rather than shelf mounted), rack grounding requirements are the same as those for the MICROLOK system. For these requirements, refer to:
S~j&t Cross Reference
Equipment Rack Grounding SM-6400B, section 2.4.3.1, page 2-6
NOTES
The MICROLOK PLUS cardfile is equipped with a single AAR stud for chassis grounding to the equipment rack. Run a minimum of #6 wire from the stud to the rack prime ground stud. Keep this wire as short as possible.
2.4.3.2 0 Volts Connection to Earth Ground
MICROLOK PLUS does not require an AC ground (0 volts connection to earth ground through capacitor) for noise protection; this is provided internally.
However, if the unit is used with a Serial Communications Adapter Panel or vital serial link modem, 0 volts on these units should be connected together and run to the rack prime ground stud through a 0.1 to 0.15 mFd, 200 volt (or greater) capacitor. Acceptable types of capacitors include polystyrene, polypropylene, polycarbonate or metalized polyester (Mylar). When the installation is complete, check the O volts to make sure it is still electrically isolated from the prime ground.
2.4.3.3 Serial and Local Cable Connection to Earth Ground
Each of the MICROLOK PLUS vital section serial communications cables (Master, Satellite and non-vital link) must be shielded. Connect the shields on these cables to earth ground on one end only. For vital serial interface cable schematics, refer to:
Subject
Vital Serial Cable Schematics
Cross Reference
SM-6400B, section 2.9.4, pages 2-46 through 2-59
NOTE
The redundant-CPU schematics in this section are not applicable to the MICROLOK PLUS system.
6500, p. 2-4
The serial and local I/0 cables to the non-vital PCBs should be provided shielding, especially if the MICROLOK PLUS unit is being used in a high-noise environment. When using shielded cable, connect one end only to earth ground. For non-vital serial and local interface cable schematics, refer to:

2.4.4 Power Supply 5 Volt Adjustment (See Figure 2-3)
A field-adjustable, trim potentiometer is provided inside the Power supply Drawer to refine the 5 volt output of the power supply converter. The 5 volt output powers the cardfile internal electronics. To access the potentiometer, slide out the drawer several inches. This can be done with power turned on.
1. Connect a digital voltmeter leads to test points TPl and TP2 to verify that input power is in the range of 19.8 to 32.4 Vdc.
2. Move the voltmeter leads to test points TP3 and TP4 to read converter module +5 volt output.
3. Adjust potentiometer as required so that converter module output (as shown on voltmeter) falls between 5.00 and 5.25 Vdc.
4. Optional step: Move voltmeter leads to +5V and OV test points on each PCB in the cardfile. This will verify that each is receiving the proper voltage level. The test points (on most PCBs) are accessible near the front edge of each PCB. Do not pull out PCB to access the test points.

MICROLOK PLUS is capable of powering two or three transmitter and receiver boards in an RFL modem used in the vital and/or non-vital serial link(s). This eliminates the need for a separate power connection and converter board in the modem. Auxiliary power from MICROLOK PLUS is provided through Faston terminals on the Power Supply. Output specifications are: 270 mA on +12 Vdc, 135 mA on -12 Vdc. This power source may also be used to operate other types of modems and devices used in conjunction with the MICROLOK PLUS non-vital serial interface; contact US&S for addition information.

2.9 VITAL SECTION SERIAL INTERFACES
2.9.1 Serial Ports (See Figure 2-5)
When the vital section of MICROLOK PLUS is configured for serial communications with another vital control system (another MICROLOK PLUS or MICROLOK), cable connections are made on either or both of the two 37-pin "D" connectors (female) on the right hand side (rear view) of the cardfile. This can include EIA signal cables that go directly to another system or modem, or EIA cables that go to an external serial communications Adapter Panel for conversion to 20 mA current loop mode.
When the vital section of MICROLOK PLUS is also configured for non-vital serial communications with the non-vital section or an external GENISYS system, the external cable connection is made on the single 25-pin "D" connector located between the two 37-pin "D" connectors. The 25-pin connector is the external interface for the Code System PCB, and is hardwired to only support EIA communications.
When the unit's vital section is linked to the non-vital section, a serial data cable is run between the vital section 25-pin "D" connector and the 44-pin PCB edge connector on the non-vital Controller PCB. This particular link can only be configured for EIA communications, even though the Controller PCB has jumpers that also allow TTL communications.
2.9.2 Cabling General Notes
US&S provides standard cables for the following serial data interfaces from the MICROLOK PLUS vital section:
Link Type Mode
MICROLOK PLUS-to-MICROLOK PLUS Vital EIA*** MICRO LOK PLUS-to-MICRO LOK Vital EIA*** MICROLOK PLUS-to-MICROLOK PLUS* Non-Vital EIA only MICRO LOK PLUS-to-GEN I SYS Non-Vital EIA only MICROLOK PLUS Internal** Non-Vital EIA only
* From Code System port (vital section) of one MICROLOK PLUS to Controller PCB Port (non-vital section) of other MICROLOK PLUS.
** Vital section (Code System Interface PCB) to non-vital section (Controller PCB).
*** Can be converted to 20 mA current loop communications via Serial Communications Adapter Panel.
Two basic types of EIA cables are available; those that allow direct connection of two or more units, and those which interface MICROLOK PLUS to a serial data modem. US&S recommends these cables be used for all vital and non-vital serial links from the MICROLOK PLUS vital section.

Direct-link EIA cables are available from US&S in various lengths up to 45 feet. Fifty feet is the US&S recommended maximum cable separation between two units in EIA communications. At greater lengths, line resistance and transient signals may cause interference with serial communications. A modem should be used when EIA cable length exceeds 50 feet, and/or the communications line leaves the equipment house containing the MICROLOK PLUS unit. MICROLOK PLUS-to-EIA modem cables are available in 20 foot lengths to allow cutting to the desired length.
2.9.3 Modem Recommendations
Consult US&S for recommendations on the modem used with MICROLOK PLUS vital and non-vital sections serial ports.
2.9.4 Vital Master and Satellite EIA Interfaces
For serial interfacing of the MICROLOK PLUS vital CPU, refer to the following:
Subject
Vital CPU Serial Interfacing
Cross Reference
SM-6400B, section 2.9.4, pages 2-46 through 2-55
NOTES
MICROLOK PLUS does not utilize redundant CPU serial interfaces. Ignore sections 2.9.4.2, 2.9.4.4, and 2.9.4.6 of SM-6400B.
Section 2.9.4.1, part A: In a MICROLOK PLUS/MICROLOK interface, the cable assembly contains two separate wires available at the connector housing. These wires are provided for the MICROLOK Satellite unit (I/0 Bus Interface PCB) to supply the VCOR drive+ and - wires. For MICROLOK PLUS, the VCOR wires may be connected from this cable assembly also, or from the Faston terminals (RLY (+), RLY (-)) on the motherboard.

2.9.5 Vital Section - Code System Interface
A. Design
NOTE
In this section, the term "non-vital controller" refers to an:
External GENISYS unit Non-vital section of an external MICROLOK PLUS unit Non-vital section of the same MICROLOK PLUS unit.
Figure 2-6 shows the standard interface between the non-vital port of the MICROLOK vital section, and a non-vital controller. In this interface, the MICROLOK PLUS vital section functions as a Satellite to the non-vital controller. The left-hand pin-outs are on the 25-pin "D" connector of the MICROLOK PLUS unit. The right-hand pin-outs are on the 44-pin connector of the non-vital controller.
Note that the shielded cable is grounded at the non-vital controller end of the interface. The MICROLOK PLUS end does not require shield grounding. Note also that various carrier control lines on the MICROLOK PLUS end are jumpered on the MICROLOK PLUS motherboard. Therefore, jumpers are not required within the 25-pin "D" connector.
The non-vital interface can only be configured for EIA communications, even though a TTL option is available on the non-vital Controller PCB.
B. Ordering References

LED Checks on Operational System
Cross Reference
SM-6300B, section 4.3, page 4-5
SM-6300B, section 4.4, pages 4-6 through 4-27/28
NOTES
Parts of this test procedure are written in accordance with the 15 I/0 slots of the GENISYS cardfile. The MICROLOK PLUS non-vital section has only two I/0 slots. Note this difference when performing the test procedure. For example, the non-vital I/0 section cannot have empty slots between boards.
The non-vital section of the MICROLOK PLUS unit is not equipped with a Power Supply Converter PCB. Board operating power is obtained from the power supply drawer. Where the GENISYS test procedure calls for turn-on and turn-off of the Power Supply Converter PCB, perform this step with the main power switch on the MICROLOK PLUS unit.
Figure 5-3 on the next page shows the configuration of the non-vital section LEDs. Refer to this figure in place of Figure 4-4 of SM-6300B.
Section 4.5, page 4-8: Steps 1 through 4 of this section are not applicable to MICROLOK PLUS. Use the following steps in their place:
1. Check the input voltage from the power source.
a. The input voltage should be in the range of 19.8 to 32.4 Vdc.
b. Make sure the supply current is sufficient and the voltage is steady when a load is placed on the supply.
2. Check the power supply converter module outputs by attaching a digital voltmeter ground to test point TP3 and the meter probe to test points TP4, TP5, TP6 and TP7. See Figure 2-3 on page 2-6 of this manual for locations.
