CP 343-2 Slave B address Read/ Write on IM 153-4 PN

Hello CP_S7;

This error happens when SFC 59 is not pointing to the correct module in your configuration.

Could you check the call of SFC 59 in your program? Compare it with the screenshot below. 

- IOID must be in byte format (b#16#54 for peripheral input addressing)

- LADDR (logical address) of the module must be in hexadecoimal format (address 256 is written w#16#1000.  This is a very common error.

The images from the screenshot are taken from these documents:
