I recently purchased a GSM modem model number SGM510 from a local dealer in Mumbai, India and I am trying to connect it to a Delta PLC that I have of model number - AS228T via RS485 port but I'm not able to connect it. The COM1 port in PLC is already connected to different multi function meters , so I'm using COM2 port in the PLC. Main aim is to write AT commands from PLC to GSM modem depending on the conditions given in ladder programming in Delta's software. I'm very new to PLC and automation in general so any help in this regard would be appreciated.
Thank you
