How to read data from SIS SZ controller

Hello,

I have 3 controllers

Safety SZ controller. Normal control module(1) is assigned to this control module

SQ controller. Control module is assigned and I read data from Control module (1) - it is ok

MX cobtroller. Similar control module is assigned and I try to read data from control module (1) but I see only bad status - red cross. I cannot read data from the control module assigned into safty SZ controller. But with similar control module in SQ controller is everythink OK. What am I doing wrong?
