Hello Gents, We have redundant system on HVAC AHU system , one of the PLC 412-5H PN/DP (FW v6.0.4; boot loader 6.00) has failed, replaced with new CPU with the same order 6ES7412-5HK06-0AB0 but FW 6.010 and boot loader 6.0.1. Uploaded backup project to the new PLC - doesn't go to RUN - came up with Error OB72 - system program different. Due to operation reasons could not stop HVAC so that Downgraded new PLC to FW v6.0.4. boot loader remains 6.0.1. Now we have Redundancy error OB72 - Link Up - update aborted due to configuration change Gents, Could you please advise ------------------------------------------------------------------------------------------ AttachmentDiagnose1.txt (376 Downloads) |
