ASCII Communication between a PLC & ASCII device through Link 150

[Luckey1001731004]

Hi Team,

I am trying to communicate an ASCII supporting relay with my PLC through Link 150. PLC to Link 150 communication is working OK as I am receiving response from Link 50 to PLC but I am not sure about Link 150 to relay communication. Although I have set all the communication parameters as per requirement.

Point to be Note:- If I communicate the same relay with PLC directly over serial port, Communication is found OK. Response was correct. Issue is in EGX with Relay communication, Also I don't know how to check ASCII data over LINK 150 Web Page. Please suggest any solution.

Are you referring to Modbus ASCII?  If so, the Option should be under Serial Port->Transmission Mode, per the manual: 

Once set, if the parameters are correct, you should be able to read registers from Diagnostics->Read Device Registers.
