The issue is that I have a machine with a PLC ELAU MAX-4 and can’t upload program from PLC. (I need to do some changes.) I’m able to monitor data with a PacDrive Diagnostics v2.1.0. I have EPAS-4 v00.24.03. I get an empty project when I trying to upload program.
While uploading the files with extension *.pro I can see the message: Receive file SOURCE.PAC xxxxxx bites. Then this project opens without any program…
I connected to PLC with Ethernet and RS-232.
Does anybody help me to solve this problem, please.
P.S. The firmware of the PLC MAX-4 is FW v00.16.42.
