PC to Mitsu Modbus Module

[nhthai 0]

Hi all, Last time I'd posted the question to connect PC to Omron controllers via Modbus, and it's okey. Now I still have a problem with A1SJ71UC24-R4-S2 Modbus Module (on A1SHCPU slot). I connect it to PC via RS232/RS485 converter using twisted cable. Though I have the manual for this Modbus Module, but it does not help at all. Is there anyone who has experience with Mitsu Modbus module when connecting PLC with PC? Any help will be highly appreciated. NHThai :
