I am receiving warnings for no assign warning messages after I updated my project from SP18 to SP19. How do I fix these warnings?

I am having an issue where the manual start/stop push buttons on the HMI are supposed to take the pumps/blowers out of auto. The logic I have attached works for the pumps, but not the blower. From what I can tell it is the exact same logic, but it is not writing a 0 to the Auto PB variable. Attached is the logic, cross reference list to show nothing else is writing to it, and the HMI screen. Any help? Am I missing something? I am using a Groov Epic PR1, my software version is 3.5 SP19 Patch 5 32 Bit.

If you add any device to the CANOpen Manager it will send messages to verify the device is on the network. Do you have the Enable expert settings check box checked in the General tab? have you added any SDOs in the SDOs tab? I avoid using the CANOpen Manager and just use the CAN_Tx and CAN_Rx blocks from the library.

All your ACT values in the PID blocks are are not valid with a NaN.

My colleague has found a tool online, Now it is possible to go to 4 GB instead of 2, which is plenty for now: https://www.techpowerup.com/forums/threads/large-address-aware.112556/ Use at own risk

I know, that is not the issue though. The issue is the HMI_Blower_Auto_PB variable not changing to false. I do not have the IO modules plugged in yet, that is why there are NaN values for those variables. That should not affect this.

Have you cross referenced the variable to see if it is being written some where else? You could try an Execute block instead of a Move.

Hello, I need to take an INT input, and convert it to a WORD value. VAR DRV2Speed : WORD; //IO card takes a WORD where 16000 = full 10V output (equivalent to 50Hz) PumpFillSpeed : INT; //Users enter a value between 0 and 50 END_VAR IF <conditions> THEN DRV2Speed :=INT_TO_WORD((PumpFillSpeed/50)*16000); END_IF </conditions> According to me this should work - but it stays at 0, no matter what. What am I doing wrong?
