TM3_Safety: Control the TM3 Safety Module

Overview

The TM3_Safety function block is included in the TM3 Safety library.

The IEC Objects tab is only available if a function block instance of a device has been created, which can be accessed by the application. To access the IEC objects, double click the module node > I/O Mapping tab.
