What can cause this error when downloading from e!COCKPIT to a PFC200? The runtime selection was verified that it’s set to e-Runtime in WBM, and tried rebooting PC&PLC.
This is likely a mis-match in the compiler version. Try aligning this in e!COCKPIT under Options >> Project Settings. If the compiler is not right, it’s also likely that the visualization compiler is also not right. If this doesn’t work you may need to update the firmware.
It can also be a problem with the IO-Check port (6226). Make sure the port is available and not blocked by the firewall.

Turns out uninstalling Codesys 3.5 somehow broke the e!COCKPIT gateway. Reinstalling e!COCKPIT fixed the issue.
