IntroductionThis manual describes the communication devices used with ProSafe-RS System.Part A describes optical bus repeater (model names: YNT511D and YNT522D) and Part B describes bus repeater (model name: YNT512D).

IMPORTANT• In this document, 10BASE-5 and 10BASE-2, terminology of Ethernet, are use to describe

the V net cables for easier understanding. Actually, V net is different from Ethernet. Yokogawa’s YCB111 and YCB141 cables should be used instead of 10BASE-5 and 10BASE-2 cables, respectively.

• V net is referred to as Control Bus.

• For the cables, connectors, T-type connectors and terminators, the models recommended by Yokogawa should be used.

• PART-A Optical Bus Repeater The optical bus repeater is used to replace a part of control bus (V net) with fiber-optic cables instead of coaxial cables. The use of this device with fiber-optic cables makes a long-distance transmission possible.

• PART-B Bus Repeater The bus repeater is used to extend the communication distance of the control bus.

n Selecting a Power Supply UnitThe ProSafe-RS system requires a power supply unit that satisfies power supply requirements in accordance with EMC regulations. It is recommended that an external power supply unit is employed in order to prevent disruptions due to momentary or extended power failure, power line noise, or lightning surges, as well as to suppress flows of harmonic current from various devices. The most proper power unit should be selected and installed after the sufficient consultation with the power unit supplier by considering the items described below.

l Source Output CapacityTake the following items into consideration to determine the output capacity when discussing with a power unit manufacturer:

Power consumption: Both VA and W data should be studied.Device crest factor: Ratio of the peak value to the effective value of input current supplied to each device.Device rush current: The method of turning on the power should also be studied.Failure backup time: Time required to back up the devices when power failsReserve capacity: An extra power capacity for any future requirement like expansions

SEE ALSO For more information about “Power Consumption”, “Rush Current”, and “Power and Ground Cabling”, see

“ProSafe-RS Installation Guidance (TI 32S01J10-01E).”

l Crest FactorThe crest factor is the ratio of the peak value to the effective value of any input current.

Crest factor =

xii

IM 32S06H10-21E 1st Edition : May 30,2008-00

The device crest factor can be obtained by dividing the peak value of the current supplied to the device by the effective value of that current. The crest factor must be considered for the input current supplied to every device connected to the system when estimating the power output capacity in selecting the power unit. Approximate device crest factors should be as follows:100 V system: About 3.220 V system: About 6.

l CommonMethodtoDeterminePowerUnitCapacityThe commonly used method in determining a power unit capacity considering the crest factor is as follows - the final determination should be made in consultation with the power unit supplier:

• If the power unit crest factor (the peak value allowable in relation to the effective value) is larger than the device crest factor, the power unit can be used to its full rated capacity. However, rush current, backup time, reserve capacity, etc., must be separately taken into consideration.

• If the power unit crest factor is smaller than the device crest factor, the power unit capacity needs to be calculated in the formula shown below. Rush current, backup time, reserve capacity, etc., must be separately taken into consideration.

Power unit output capacity = Total device power consumption x Capacity coefficient

Capacity coefficient = Device crest factor/Power unit crest factor

xiii

IM 32S06H10-21E 2nd Edition : Dec.15,2008-00

l RushCurrentA large rush current flows in to the device due to momentary capacitor-charging current or transformer-exciting rush current when the device is turned on. Thus it is necessary that no voltage fluctuation that could adversely affect any other devices is caused at least when some devices are turned on or off. Slow starting, switching to uninterruptible backup power, etc., will also be required when all devices are to be turned on simultaneously.When power is turned on the rush current could trip the overload protector and cause inadvertent switching to backup power or commercial power supply. In this connection, select a power unit that is equipped with a function to automatically resets the condition instantaneously without any break when overloading has been terminated.

l Suppressing Harmonic CurrentIn order to suppress harmonic current supplied to a low-voltage distribution system, it is necessary to install a special power unit or an active filter, such as indicated below, between a device and the distribution system:

• Power unit equipped with a harmonic current suppressing function (a high power-factor inverter-type uninterruptible power unit, etc.)

• Active filter unit for suppressing a harmonic current

In Europe, a power unit should be selected so the requirements for harmonic current are properly met in accordance with EMC regulations. The capacity of the harmonic current suppressing unit should be determined in consultation with the power unit manufacturer by following the similar way as the selection of power unit’s output capacity previously discussed.

n Drawing ConventionsSome drawings in the user manual may be partially emphasized, simplified, or omitted, for the convenience of description.Note that screen images in user manuals may be slightly different from the actual ones (for example, display positions and case differences), and some show only example images.

n IntegrationwithCENTUMProSafe-RS can be used by integrating with CENTUM VP or CENTUM CS 3000. In the User’s Manuals of ProSafe-RS, the integration with CENTUM VP or CENTUM CS 3000 is referred to as “Integration with CENTUM.” For the same features of CENTUM VP and CENTUM CS 3000 that have different feature names, the name used in CENTUM VP will be referred to in the explanations. (For example, CENTUM CS 3000 System Alarm Window and CENTUM VP System Alarm View have the same functions, but only System Alarm View will be referred to when explaining this feature.) Nevertheless, if there is any difference in functionality according to whether ProSafe-RS is integrated with CENTUM VP or CENTUM CS 3000, the feature will be explained separately for both cases.

n Installation of Rack Mountable DeviceObserve the following when you install an optical bus repeater (OBR) on a rack or an instrument panel.

l InsulationfromtheRackInsulate the rack mountable OBR from the rack by attaching insulation bushings. Fasten a pair of insulation bushings together to each of the screw holes on the plate or the bracket on the OBR to prevent the OBR from touching the rack. And then screw the OBR to the rack. After screwing the OBR to the rack, confirm that the OBR is electrically insulated. Insulation bushings are supplied with the rack mountable OBR.

WARNINGWhen you install the ‘OBR with insulation bushings attached’ on a rack or an instrument panel, do not keep the OBR hung on loose screws in an unstable status. Too much force may apply to the insulation bushings and cause damaged or broken insulation bushings.

l Installation Procedure 1. Fasten a pair of insulation bushings together to each of the screw holes on the plate or the

bracket on the OBR. The tapering end of the insulation bushings must come to the front side where a screw enters.

2. Using four M5 screws to fix the device onto the rack or the panel.

A3.4 ConnectingtheOpticalCordThis section explains the procedures to connect the optical cord to the mounted optical bus repeater.

WARNING• Before connecting or disconnecting an cord plugs, turn the power switch to off on both the

local and destination optical bus repeaters. Connecting or disconnecting the cord plugs while the power is on may disrupt the entire communications bus system.

• Since the repeater is applied with dual-redundant configuration, be sure to connect bus1 and bus2 respectively to the corresponding transceivers.

• In a dusty environment, the protective caps of both the optical transceivers and the optical cords should not be removed.

n PrecautionsWhenConnectingCordplugs• Remove the protective caps from the optical transceiver and cords. Before connecting an

optical cord, clean the connection end with a gas-type blower (available in camera stores). If a low-temperature gas blower is used, blow several times from approximately a 10-cm distance, but only for two or three seconds at a time.

• If an optical connector has been disconnected on an occasion, such as for replacing the optical transceiver, immediately place a protective caps on the optical transceiver and cords to keep dirt away.

• Store protective caps in a clean container or bag, and clean them out with a gas blower immediately before use.

• Be careful to keep the end of the optical cord from touching human bodies and other objects. If it has touched something and is suspected of being soiled, first wipe it with a gauze pad moistened with high-purity alcohol (which has been stored in a clean condition), and then clean it with a gas-type blower.

• Optical cord plug has a key and the connector has a key groove. Push the plug deeply into the connector only after the key is placed properly in the key groove.

A3.4.3 Corresponding to GI 62.5/125 Fiber-optic CableIt is recommended to use a GI 50/125 fiber-optic cables (core diameter 50 µm, clad diameter 125 µm) for an optical bus repeater.Follow the procedure below to apply a GI 62.5/125 fiber-optic cable. Compared to a GI 50/125 fiber-optic cable, a large volume of light is emitted by connecting a GI 62.5/125 fiber-optic cable to the output connector of an optical bus repeater. If the input connector of an optical bus repeater receives a larger volume of light than the maximum volume of light which can be received, data transmission fails. Therefore, connect a GI 62.5/125 fiber-optic cable according to the procedure below.1. To restrict a volume of light, you must insert a 10 m of GI 50/125 optical cord between the

output connector of an optical bus repeater and a GI 62.5/125 fiber-optic cable in the field.2. To connect the two types of cables, use an optical adapter inside the splicing box located

under the floor near a cabinet to install an optical bus repeater.

A3.4.4 Fiber-optic Cable InstallationThe fiber-optic cable for field installation must be strong. Use flexible optical cords where the cable is connected to the optical bus repeater. The interconnection of the strong cable and flexible cords is generally made in the splicing box under the floor.

n PrecautionswhenInstallingFiber-opticCableThe total loss in a cable installation must be 6 dB or less for 4 km, max., or 18 dB or less for 15 km, max. at the 1.3 µm wavelength. The cable system loss must be measured at the time of each installation.Loss measurement may possibly vary by ±0.5 dB due to the variance in the optical cord in measuring the stabilized light source output level, repeatability of connecting and disconnecting the plugs, and others, even if a calibrated light meter is used. The as-installed measurement data must allow a minimum margin on the order of 0.5 dB over the permissible loss.

n A Sample Calculation of Loss in Optical FiberThe following figure shows an example of estimating the loss in an optical fiber. The optical bus repeater for 4 km, max. is used. The fiber-optic cable has a loss of 1 dB/km, and is connected by fusing every 500 meters. The loss in each fused connection is generally estimated at 0.1 dB for fiber-optic cable to fiber-optic cable, and about 0.3 dB for fiber-optic cable and optical cord.

When the power is turned on with the setting at left, loopback diagnoses are performed in the following order while the controller RDY lamp remains off: 1. Controller internal loopback 2. Transceiver 1 internal loopback 3. Transceiver 2 internal loopbackIf no error is found, the controller RDY lamp lights up and the mode changes to communication status.If an error is found by the loopback diagnoses, the controller RDY lamp remains off but an error code is indicated by the error code lamps. The diagnoses are repeated from the start, and the mode changes to communication status when the diagnoses end successfully.

In this test, no test signal is output to the cable. However, it is recommended that the transceiver branch connector be disconnected from the V net cable.In this mode, the controller RDY lamp remains off.When the power is turned on with the setting at left, the controller internal loopback is performed once, then the transceiver 1 and transceiver 2 internal loopbacks are repeated. While the internal loopbacks are being repeated, all error code lamps remain on.While this mode is executed normally, the statuses of the RCV and SND lamps for both transceivers are as follows: (both transceivers 1 and 2) RCV lamp: ON SND lamp: undefinedIf an error is found at any stage, the error code is indicated and the test stops.

If this mode is executed, a test signal is output from the transceiver to the cable. Thus, when starting this diagnosis in a system currently running, it is necessary to disconnect from the V net currently operating.When executing this mode, disconnect the V net cables from both transceivers1 and 2 and install four terminators to the branch connector.In this mode, the controller RDY lamp is off.While this test is executed continuously and properly, the SND and RCV lamps for both transceivers remain on.When the power is turned on, one each of the following diagnoses are performed in this order: 1. Controller internal loopback 2. Transceiver 1 internal loopback 3. Transceiver 2 internal loopbackIf no error is found, the following are repeated: Transceiver 1 external loopback Transceiver 2 external loopbackWhile the external loopbacks are being repeated, all error code lamps remain on.If an error is found at any stage, the error code is indicated and the test stops.

*1: When performing an internal loopback, it is recommended that the cable be disconnected from the V net currently operating in order to prevent a system shutdown due to malfunctioning or mis-operation.

*2: When performing an external loopback, a test signal is output from the transceiver to the cable. Thus, be sure to disconnect the cable from the V net currently operating.
