Dialog: Properties – POU (under SafetyApp)

In addition to the standard properties, each POU located under the SafetyApp has the EtherCAT Safety Deactivation and Group IOs properties.

The Properties dialog is opened by selecting the respective POU in the project tree and clicking the Properties command in the context menu.

Tab: Deactivation

This tab is available only for the EtherCAT Safety Modules EL6910 and EK1960.

Figure 35. Dialog: Properties – POU – Deactivation

The deactivation methods for the group of this POU are defined on this tab. A "Group" is understood to be a POU running in the Safety Module with its respective logical devices. Methods which are not activated are not available in the online dialog (see Online Deactivation of Groups).

Permanent Deactivation	Allows the group of this POU to be permanently deactivated. If this deactivation method is selected in the online dialog, then the substitute values for the POU outputs are set (see: Deactivation – Substitute values).
Temporary Deactivation	Allows the group of this POU to be deactivated until the next time the EtherCAT Safety Module is switched on. If this deactivation method is selected in the online dialog, then the substitute values for the POU outputs are set.
Passivation	Allows a group with exactly one FSoE Module to be deactivated when the connected device has been disconnected from the installation. After deactivation by online command, the connection defined in the group must report a `COM error` within the Timeout Passivation time (default value 10 seconds). If the device is still present after the Timeout Passivation so that no `COM error` is reported, then a group error is set and a corresponding diagnostic message is generated.
