I have inherited a starter kit from another person at my company who has since moved on to another office. There was another program on it and I cleared it out to reinstall the standard starter kit project. The firmware was also updated during this process to 2020.3. I’m having some issues with the data (Execution values) on any of the data lists. The HMI works properly and I can see state changes within that program. I can read the data within the PLC like the system variables. But for some reason no matter what I try I can’t even get the DIs to show true or false. Is there some setting somewhere that I’m missing to enable the IO to show up in PLCNextEngineer?
Hi, one reason might be that your bus is not running. Please go to the diagnostic section of the WBM and check if there are any errors in your bus or your configuration. If so, please fix the errors and than you probably will see online values for your I/Os.
