omron plc to gsm modem

[shltan 1]

Hi all, can anyone kindly help me in setting up gsm modem communications between the plc and pc, e.g. to go online with the cx-programmer. I'm unable to establish communications even by following the guide found in this forum Thank you.

It would help if you mention the modem type, PLC CPU type, connecting port, cable diagram you (intend to) use, etc. etc. Details!!
