I have a potential upgrade and would like to find a modem that will work better than the current system.
Basically, we will have an HMI. This HMI had WinPLC with an interface that used the internal modem to dial out to 8 sites in a polling fashion to get updates to Modbus data points.
The plant went to RSView recently and they would like to put this system on RSView. In the future, we will go radio modems, but for now we are stuck w/ phone lines.
I'm looking for a programmable modem that can be setup to dial various numbers in a polling fashion to achieve the same task. I do not want to have to write an interface in RSView to achieve this goal.
Any ideas....
Thanks,
Pat
