I/O bus error

[hfatali]

Hello everyone 

I started to work with unitronics all in one (plc+hmi)

My hmi is usp-156-x10

I'm installed io card and configured modules.  I get this error when I download the programs:

I/O bus error [code 1]

App i/o is ok. But identified i/o is" ????"

My modules card is : uid-o8o8r & uia-0402n

What should I do?

For starters make sure the firmware in your PLC matches the version of UniLogic you are using.  Then upload your program so we can check it or contact Official Unitronics Support at support@unitronics.com.
