Good morning, I am facing this problem since 4 months ago which is getting a nightmare. I am getting the following error which makes CPU goes to STOP every 2 weeks aproximately. "Error: Safety program: Data corruption prior to sending to F-I/O F-runtime group 1 Start address of the F-I/O: 20 Offset of the output 1" This address is related to a S7-1500 F-DQ card (6ES7 526-2BF00-0AB0) so I read the information regarding finding errors: " Finding errorsThe additional information below helps you to identify errors:
Offset of the output means the offset of the first defective byte beginning with the start address of the module. Offset = 0 .. n: error in the channels " So according to this, taking into account the card has 8 channels, it looks like offset 1 is an error in the channels. So I checked all the outputs and they are not written any other place, just safety program. I thought that It might be overwritten the Input/output area, so I changed the output area from 20 to 15 not changing the tags and I keep getting the same error (as you can see in the attached document). I already contacted with Siemens support 3 times and they do not really help me at all. I read all forum threads about this error and the problem is that in just a couple of the the OP posted how they solved it, but the rest they did not. I would really appreciate any help Thanks in advance. AttachmentData_Corruption_Problem.pdf (4 Downloads) |
