AC500 eCO connectivity over GSM/GPRS
I need to know if it is possible to connect the AC500 eCO to a GSM modem with serial MODBUS or MODBUS TCP for functioning as RTU in a SCADA network and if there are any limitations for such use.
The all limitations are depend upon your master device..
Can you brief out your complete Architecture...So we can suggect you more things..
As if you want to use ECO PLC as RTU then just configure your PLC Communication PORT as Modbus Serve in Automation Builder and put your TAGS in Global Variables along with modbus address (%MW0.0 is equals to 40000 standard modbus address).
I suggect you to check simple prototype initially with any third party Modbus Master tool along with your GPRS device.
I hope it will helps you.
