Omron modbus TCP/IP, multiple masters

[VAU_RMA 3]

Hi. Does the CJ1W-ETN21 PLC card / modbus TCP protocol accept multiple simultaneous connections? (I have a modbus server (slave) connecting to multiple modbus clients (masters)) The situation is like this: I have a installation that shall be talking to another system (a main control system). This main control system uses modbus TCP/IP to communicate with all the other installations, an will do so against mine as well. The main control system uses two modbus clients for redundancy. The question is then if the omron CJ1W-ETN21 card and modbus TCP/IP protocol (Can those FBs in the mrPLC download section be used for a modbus TCP/IP server. I have got a program called "ModbusTCP V1_4" witch I got from Omron Norway, that looks like can be used for both client and server. Anyone know this program?) can be used with two clients / two TCP/IP connections at the same time. Edited 12 Apr 2010 by VAU_RMA
