Hello, With the list 0694, the Index refers to the Profinet IO system you read. Index 16#64 is 100 in decimal. This is the ID number of the upper PNIO system in your drawing (first CPU). By reading the same list but with index 16#65, you will read the PNIO at the bottom (second CPU). You can obtain information on the current status of the fault-tolerant system from the partial list with SSL ID W#16#xy71. The details of the list can be found in the standard and system functions at chapter 34.19 (H-Group information). You will know which CPU is Master. Another way to know the active channel is using SFC49. Here an extract of the manual. |
