Hi there,
I am new to PLC world and I am trying to do basic programming now. I am trying to read data from an input register of a device on the network but not sure why I am not able to read the data and also not sure why my program says suspended at the bottom?
If anyone could help please? I am struggling to start here..
Many Thanks
Suspended code blocks is an advanced feature when the PLC is in RUN mode.
Since this is a "new" project, I would recommend you first clear your PLC (PLC->Clear). Uncheck the "Re-read the project after clearing", that way your current project in Designer will not also be cleared. After clearing, Write the Project to the PLC. That should get you going.
If you are new to PLCs, I recommend watching some videos - see the Start Page in Designer. There is a video library under Help->Browse Videos. You should learn about the I/O Logic Scan, Program vs. Run mode, etc.
