Troubleshooting DH+ Network Error on PV 1400e HMI: SLC 5/04 Program Offline Interference

Question:

Greetings, everyone! I recently made alterations to the PV 1400e HMI program by uploading a .pvc file via Ethernet and then downloading the changes as a .pvd file to the HMI. However, I am now facing a DH+ communication error. When the DH+ cable is connected to the HMI, the SLC 5/04 program intermittently goes offline. I have encountered an error message related to this issue. Your assistance is greatly appreciated. Thank you.

Hey there! It seems like the issue you're facing might trace back to a potential hardware disruption or configuration error. Start by checking the DH+ cable to make sure it hasn't been damaged in any way. Also, verify that your SLC 5/04 processor's properties are set correctly within RSLogix 500 and that the HMI is using the correct DH+ node address. If all else fails, try to create a new .pvd file and download it to your HMI. Hopefully, this should resolve the issue. Keep us updated!
