For more information about configuring Dual Ethernet mode, refer to the section Choosing the Dual Ethernet Mode.

ATTENTION

The Web Server is provided free of cost when you purchase Firmware. Separate software is not required to install web server. While installing Firmware the Web Server is installed automatically.

1.3 Communication Ports Overview The Honeywell RC500 I/O Tool Kit modules have the following communication ports and connectors for wiring.

Ethernet I/O-2 product Two Ethernet ports

– style USB port style RS485 port style

Applicable to all modules in the product family

RJ45 (shielded) Type B (shielded) Screw Terminals

Ethernet Port A 10/100 BaseT dual Ethernet ports are found on all units. Standard RJ45 connectors are provided with standard 802.11 pin-outs. These ports have fixed unique MAC addresses. The IP addresses can be set using the Honeywell RC500 I/O Tool Kit software or through a web browser.

It is recommended to use data-quality (not voice-quality) twisted pair cable, rated category 5 with standard RJ45 connectors. For best performance, use shielded cable. Ethernet I/O-2 modules have an auto-crossover feature and may be connected with either straight through or crossover type cables.

USB Port The USB port is intended for configuring the module only. It is possible to make I/O requests through the USB port in RC500 protocol. This port may not be configured as a Modbus port.

1. Introduction 1.4. I/O Functions


RS485 Port The RS485 port is found on the base of all Ethernet I/O-2 modules. It provides a RS485 (2-wire, half duplex only) connection to other RS485 equipment. Screw terminals are available for RS485+, RS485-, RS485 GND and RS485 termination.

1.4 I/O Functions The following are the characteristics of the various I/O functions of Ethernet I/O-2 module.

• High density discrete inputs

• Sourcing/sinking input option

• Low threshold inputs

• Discrete input counter feature

• High speed counters

• Slow/fast response for all discrete inputs

• Combination discrete inputs/outputs

• High density discrete outputs

• Isolated discrete outputs

• Voltage range analog inputs

• High speed analog inputs

• Analog outputs

• Watchdog output



High density discrete inputs The high-density discrete inputs are applicable to the following modules.

• RC-EIO2MIXT1-D

• RC-EIO2MIXT2-D

• RC-EIO232DI-D

Standard high-density discrete inputs accept input voltages in the range of the specified power supply voltage (10 to 30 V DC) and are referenced to the power return (-) to simplify field wiring. These inputs are the sourcing type that indicates an ON condition when a positive voltage source above the threshold level is applied to them. These inputs may be filtered to make them immune to short duration voltage spikes or mechanical contact bounce by configuring them for Slow Response, which is approximately 6 mS.

Discrete Input Range 10-30 V DC

ATTENTION

The default threshold level is 9 V.

Sourcing/sinking input option The sourcing/sinking input option is applicable to the following modules.

• RC-EIO2MIXT1-D

• RC-EIO2MIXT2-D

• RC-EIO232DI-D

The first eight discrete inputs (terminals 11 – 18) can be configured as sourcing inputs (ON when positive voltage is applied) or sinking inputs (switch closures to ground). There is a selection jumper in the module’s base that can be easily accessed by removing the logic module and changing the DI jumper (For more information, refer to Honeywell RC500 Hardware planning and Installation Guide). After the sink/source is configured for DC- or DC+, the module’s firmware performs a consistency check to verify the hardware and software selections. When the module is configured for Follow Jumper, the module’s firmware takes the state of the jumper.



Low threshold inputs The low threshold inputs are applicable to the following modules.

• RC-EIO2MIXT1-D

• RC-EIO2MIXT2-D

• RC-EIO232DI-D

The first group of eight inputs may be modified to transition at a threshold voltage lower than the factory setting of 9 volts. This is accomplished by soldering a resistor into the wiring base, which is located along with the DI COM jumper.

Note: This modification is recommended for advanced users only.

Isolated discrete inputs The isolated discrete inputs are applicable to the following module.

• RC-EIO216DI-D

These inputs utilize two screws per input channel so that each input is isolated from all other channels and the module’s internal circuitry. Except for the isolation characteristic, these inputs have the same characteristics as the high-density inputs, including the counter functionality.

Discrete input counter feature The discrete input counter feature is applicable to the following modules.

• RC-EIO2MIXT1-D

• RC-EIO2MIXT2-D

• RC-EIO232DI-D

• RC-EIO216DI-D

The following are the Counter Modes.

• Count Up

• Pulse Timing

• Pulse Rate

For more information about enable counters, refer to the section Enable counters.



For more information about counter range, refer to the section Counter range.

High speed counters The high-speed counters are applicable to the following modules.

• RC-EIO2MIXT1-D

• RC-EIO2MIXT2-D

• RC-EIO232DI-D

• RC-EIO216DI-D

High speed counters can be enabled on the first two channels. In the web server or Honeywell RC500 I/O Tool Kit, select Enable high-speed counters on Channel 1 and/or Channel 2 modes in the Discrete Options page. This special mode functions identical to the discrete input count feature for the corresponding input, except that the maximum count rate for the first and/or second input is increased to 50 kHz (3,000,000 pulses/min). The maximum count rate on isolated channels is 2 kHz.

Note: On the RC-EIO2MIXT1-D module, the first high speed counter is connected to two isolated input screw terminals (43 and 44) and screw terminal 11 is disabled. If the high-speed counter option is not selected, then the pulses are counted from the ordinary discrete input screw terminal as in other input channels.

Slow/fast response for all discrete inputs In the web server or Honeywell RC500 I/O Tool Kit software, select Fast response (no filtering) for instantaneous input updates. DC input changes are detected as fast as within 1mS. Selecting the Slow response setting helps the module to look for stable inputs for approximately 25 mS. This setting, filters the contact bounce, which often happens while counting mechanical switch closures in noisy environments.

Combination discrete inputs/outputs The combination discrete inputs/outputs are applicable to the following modules.

• RC-EIO2MIXT1-D

• RC-EIO2MIXT2-D

The third group of eight discrete I/O has both input and output capabilities at the same time. Output functionality for a given channel might be individually enabled in the Feature column of the Discrete Options page. For compatibility with I/O, drivers to write I/O in fixed blocks, all eight Y (output) registers are always assigned. Only outputs that are enabled may be turned ON. Other output values are masked in the I/O module.



All eight channels are always active as inputs. Channels that do not have their output function enabled may be used as inputs. For channels configured as outputs, the input functionality may be used to detect faults in the corresponding outputs.

Note: To avoid leakage paths or damage to the I/O circuitry on I/O modules, it is recommended that the same power supply must use to power the I/O module and input devices connected to these special I/O channels. If a voltage source is applied to the eight combination I/O channels that exceed the voltage supplied to the rest of the I/O module, it may result in unintended power paths.

High density discrete outputs The high-density discrete outputs are applicable to the following module.

• RC-EIO232DO-D

It provides the following outputs.

• Individual maximum outputs are rated for 1 ampere per channel, 8 ampere total per module. Short duration current as high as 2 ampere is permissible.

• Sourcing switched output power at the voltage supplied to the module’s supply voltage input (less than a nominal voltage drop in the output’s power switching device).

• Current limiting is not provided on the outputs of this module.

Isolated discrete outputs The isolated discrete outputs are applicable to the following module.

• RC-EIO216DO-D

It provides the following outputs.

• Individually isolated outputs rated for 1Ampere/channel at temperatures up to 60°C. (0.75 ampere at higher temperatures). Current limiting provided on each output.

• Two screw terminals, isolated from all other outputs and the module’s internal circuit, for each channel.

• Any voltage up to the rating of the module may be applied to each individual output.



Time Proportioned Outputs The Time Proportioned Outputs (TPO) is applicable to the following modules.

• RC-EIO2MIXT1-D

• RC-EIO2MIXT2-D

• RC-EIO232DO-D

• RC-EIO216DO-D

The discrete output channels in all Ethernet I/O-2 modules are capable of functioning as TPO. TPO pulse ON and OFF with a duty cycle proportional to an analog value stored in a corresponding analog output register. TPO outputs are a low cost way to get smooth proportional control of heaters and other process variables. Typically, TPO analog output registers are assigned to the output of PID or other control logic in an ISaGRAF or other control program. Use the module’s web interface or the Honeywell RC500 I/O Tool Kit software to set pulse cycling as fast as 10 mS or as slow (many minutes) as your system dynamics require. Each output may be individually configured as a TPO or as an ordinary discrete output.

Examples

In this example, TPO #1 has a 10 second cycle time and the analog value is 3276 (10% of full scale, which is typically 32767). The output is ON for 1 second and OFF for 9 seconds during each 10 seconds period.

TPO #2 has a 2 second cycle time and the analog value is 26214 (80% of full scale). The output is ON for 1.6 seconds and OFF for 0.4 seconds during each 2 seconds period.

TPO #3 has a 2 second specified cycle time, an analog value of 820 (2.5% of full scale) and a minimum ON/OFF time of 100 mS. Since the minimum cycle time is 100 mS and the calculated ON time is only 50 mS, the cycle time is readjusted by a factor of 2 to maintain the time proportion. The output is ON for 100 mS and OFF for 3.9 seconds before repeating.

Note: Non-integral remainder of time is carried forward to the next cycle to maintain long-term accuracy. (In example for TPO #3, the below minimum time is carried forward to the next time cycle. When the below minimum value is calculated, no ON time is set for that cycle.



Voltage range analog inputs The voltage range analog inputs are applicable to the following module.

• RC-EIO232AIV-D

The input range on modules that have voltage range inputs is 0 volts to +10 volts. The high 16-bit resolution of the inputs generally permits adequate reading resolution for lower voltage input signals.

High speed analog inputs The high speed analog inputs are applicable to all modules with analog modules.

The first two analog inputs on all modules with analog inputs may be configured as high speed analog inputs. Analog input channels configured in this manner, update as fast as 1 mS but at the expense of having only 10 bits of reporting resolution.

Note: By default, analog inputs integrate their 16 bit reported results to provide outstanding noise rejection. The scan time of this 16 bit, vary with user configuration settings.



Analog outputs The analog outputs are applicable to the following modules.

• RC-EIO2MIXT2-D

• RC-EIO28AOM-D

• RC-EIO2AIAO-D

Analog outputs on all applicable I/O modules in this product family have a 4-20 mA output range and may be incremented (varied) with a full 16 bit resolution corresponding to the value in the associated analog output (AY) register.

Watchdog output The watchdog output is applicable to the all I/O modules. A microprocessor in the module continuously monitors several user-selected system functions. Additionally, an independent CPU watchdog microprocessor in the module also monitors the main CPU and used to indicate a failure of the main CPU. The following are the watchdog options (as selected in the web interface or Honeywell RC500 I/O Tool Kit software).

• Power 1 Failure

• Power 2 Failure

• Ethernet Ring Failure

• Watchdog CPU Monitor

• No I/O Poll in

The default state of the Watchdog Output (screw terminal #9 on the I/O module’s wiring base) is ON (True). If an error condition in any one of the user-selected parameters is detected, the watchdog displays the output in OFF (False) state.

The default watchdog time is 3 seconds, and may be set as high as 65 seconds to allow for telemetry equipment or application-related program delays. The timer period selected is applied individually to each watchdog function selected.
