Hello,
I write from Portugal, sorry if my english don´t is the best.
I have a problem, i have a GE Cimplicity Scada for automation control. Now, i buy a Unitronics HMI + PLC for automate a litle pumps and flow meters but have a problem, I have the plc connected to GPRS modem and comunicate to SCADA SERVER via VPN. The protocol is MODBUS comunication and the scada ping's PLC normaly, but dont comunicate between them correct. I load the 40000 + points and the scada read's NOTHING.
I need a software or something else for convert the values come from PLC or have a specific "comunication rung" ?
Appreciate all answers and helps. Thnxs a lot
