I got similar great help from these guys in the past as well. For a little contrast, we are having problems with a machine that uses an AB plc and HMI and we don?t have any other AB plcs. Just got a a quote for software to talk to the PLC, HMI and Servo drive $6995! Yeah right, I could toss the Plc, HMI and use a C-More & BRX and save $5K. Might do it too. 8 thermocouple inputs running 8 heat zones and the temperatures track really poorly.
