What's the different between Modbus TCP server and Modbus TCP slave device for M258 Ethernet?
Modbus TCP serverModbus TCP slave device
Only configure IP addressNeed to configure parameters and I/O mapping
For Modbus TCP client, all %MW address of server can be R/W.For I/O scanner, only %IW area (2~40 words) can be R/W, %QW area (2~40 words) are read only, and actual %MW address of slave device cannot be visited.
No need to configure “Unit ID”Unit ID (1~247) should be same the unit ID setting in Modbus TCP I/O scanner.
No visualized list for communicated address.Have a clear and visualized interface to monitor all communicated variables.
The connection to one client may be closed when more than 8 connections are needed.The connection to the Master client is never forcefully closed, when IPMaster Address is configured.
