HI All.I used XA2[1] for voltage and digital inputs for MD4,While testing I got "NO Contact" Error in RED color as I did not connect any expansion units.Can I give these input values directly to MD4 with CAN and without using Expansion unit XA2[1] connection?
The value of the channel will be set to the 'Error value' that you define on the voltage input.
Without the XA2 connected you will not be able to get any other values on those channels.
The status 'No contact' comes from as you say, do not have any contact with the XA2 that the channels are connected to.
If you just want to test the application and be able to assign values to the channels without connecting everything i suggest using the simulator instead.
