Dear Experts,
I have a multiproject with two Non-Redundant AS (CPU 410-5H). I checked the diagnostic buffer of the PLCs and found a problem.
On the first PLC the problem is only read IO error which is caused by inactive DP Slave.
On the second PLC the diagnostic buffer is full of only one message repeatedly coming every few ms :
Event 1 of 3173: Event ID 16# A217
No Entry in text database. Hexadecimal values will be displayed.
Event ID :16# A217
OB : 16# 01
PK : 16# 01
DatID 1/2 : 16# 50 C0
Additional Info 1 / 2 / 3: 16# 80C3 0000 3FE6
Outgoing Event
The CPU configurations are typical for both PLC, so i doubt it comes from the CPU config.
One thing I notice is PLC1 has SFC 51 included in the Block folder, but not called directly in the CFC, while PLC2 doesn't have SFC 51 or SFC 52 included in the Block folder.
Can anyone help me to find this root cause?
Thanks a lot.
