How can I connect AC500 PLC to GSM moderm
I have 3 remote flow meter that have GSM/GPRS module with WITS protocol. I want to collect data from its to the computer. I intend to use a GSM/GRPS module (such as PSI-MODEM-GSM/ETH of Phoenix Contact) to collect data from the flow meters and then transfer it to AC500 PLC.
How can I do it?
