grinHello, my men,

 File attachment.

 I got a problem when I using function "LED"(Read LED status) from library in STEP7 V11 SP2.

 I used the "LED" function and "Ret_Val" return error code 16#8091 or other error codes.

 I don't know for the parameter LADDR (Read LED status), what I should filled in??? I don't know

 what's the HW identifier of the CPU, either.

 And for parameter "LED"  what I should filled in??

 Please help me and give me specific solution.

 Thanks a lot.

Hi,

I suggest you try to use the simbolic name of your cpu diagnose interface (e.g. PLC_1) as the direct number (65).
