Can possibility to disable port interface of 6ES5 943-7UB21 (SI2) ?
I means, i had exising project. The projectis detail below :
| S5-115U | "SI2" --------------------------" No use "
| CPU943B|
|| "SI1" -------------------------" OP7"
I saw CPU card of S5-115U (6ES5 943-7UB21) , It have two port that is "SI2" and "SI1" and than I think I can communicate both port. Ohhhhh my god , I can not communicate with "SI2" port. So I back to read 6ES 943-7UB21catalog, In thecatalog it tell us it can communicate two port. So I would like to ask you can we disable "SI2" port.
I ask you because when I online to CPU i must un-plug OP7 from CPU. That means, It hard to check between CPU-S5 and OP7 program.
Best regards
