Two cents more...
Used one on a tank burst test station.
With regards to the analog signal bouncing around a lot, I also experienced that when the 0v was tied to a terminal block with other devices. Ended up landing it on the 24v power supply, and all my fluctuation went away. Why, I dasn't know. Just a mechanical guy who dabbles in controls. Loops of some sort I suppose.
I'll echo the thoughts on the display. HMI programming was good, plc programming was ok, but as the unit uses the same serial port to communicate between the plc and hmi side, required constant flipping of flippin' dip switches. Impossible to monitor the program function in real time and run the hmi at the same time. That really s**cks.
Also didn't care for wiring all i/o back to a door mounted device. I'd rather have the i/o terminations on the backplane.
In the future, I also will use their touchscreens, but not their plc's.
