OPTOMUX B2 to Ethernet Converter

I have 5 separate systems each with: 4 each 16CH. ANALOG RACK (PB16AH) 4 eachOPTOMUX ANALOG BOARD (B2) RS-422 8 each ANALOG INPUT MODULES (AD7) 52 each RTD INPUT MODULES (AD10T2) I want to communicate to the 5 control groups via Ethernet. I would like to have two Citect I/O servers connected to them each with access to the I/O. Do you know of a reliable device to use with OPTOMUX and do you know of one that can have two servers access the data?

How about the following suggestion for starters FactoryFloor running on LCM4 controllers allows the use of Optomux communications through the three integrated RS485 com ports. Adding an M4SENET-100 card to the controller would give you full Ethernet TCP/IP and facility to use the OPCV2.0 server from Opto22, giving you the connectivity to Citec you are looking for. Some OptoControl application code would be required to poll the Optomux data from your B2 brains and leave it in tables or variable in the controller, but I'm sure the nice guys at Opto22 already have what you need. The basic command you would need is hiding quietly in the Communication Commands group
Transmit/Receive OPTOMUX String
From.........................OPTOMUX_COMMAND.............[String Variable] On Port.....................1..............................................[Integer 32 Literal] Put Result in.............OPTOMUX_RESPONSE............[String Variable] Put Status in.............ERROR_CODE.........................[Integer 32 Variable] OptoScript Example:
TransReceOptomuxString(String, On Port, Put Result in) Error_Code = TransReceOptomuxString(Optomux_Command, 1, Optomux_Response);
A possible lower cost solution for the amount of data you are moving would be to use an SNAP-LCE Ethenet controller, but note that ioProject does not at present support Optomux protocol directly, but you can easy construct the necessary commands using subroutines and ASCII to give the same functionality. Finally, the use of any Opto22 controller allows the use of OptoDisplay or ioDisplay, an operator interface directly comparable with Citec for your SCADA/HMI requirements at a lower price.
