Configuring the Safety-related TM5/TM7 Modules

Overview

In general, safety-related outputs can only be written by the SLC.

To enable the SLC to switch an output channel directly (via the safety-related application, programmed in Machine Expert - Safety) without an enable signal (acknowledgment) from the standard application, the output channel must be configured as described below.

Procedure in EcoStruxure Machine Expert Logic Builder:

Step	Action
1	In the Devices tree, double-click the respective TM5SDOxxx module to open the parameter editor and click the tab User-Defined Parameters.
2	Set the parameter CentralControl_DigitalOutputs_xx (where xx is the channel number) to Direct.

For further information on this parameter and a description how to use the enable signal from the standard application instead of direct switching by the SLC, refer to chapter Enabling a safety-related output (acknowledge) via the standard application.
