I need to send simple short ASCII commands like F002 to a very simple device, and then listen for single character responses. Hyperterminal works for this so that demonstrates how simple this back and forth is.
My issue is that I have used a PLC-5 for this for decades and it needs to go so I’m looking for an way to send these simple commands from newer controllogix or compactlogix PLC’s . Ideally from any number of source PLC’s though that might not be possible.
The EN2SE-R was recommended to me, I have looked all over for example code and all I find is modbus. Has anyone done this that can can show me some screenshot examples of how this looks inside the PLC code?
