Module parameters - Safe outputs

Configuration status
For operation of the switching group the AS-i master must activate communication with the
associated AS-i address of the control unit in the F-CM. For this reason the configuration of
the AS-i network must include a virtual AS-i slave with the profile IO.ID.ID2 = 6.B.D and ID1
= 0. If the slaves are not configured, the AS-i master must be set such that the AS-i address
of the control unit in the F-CM is actively operating, for example, using the "SET" button of
the master while the F-CM module is being configured and connected to the AS-i master.
Activate output control
With this parameter, you activate the corresponding switching group and the associated AS-
i address of the control unit in the F-CM AS-i Safety ST module.
You will find additional information in Section Operating principle of the safe AS-i outputs
(Page 36), "Operating principle of the safe AS-i outputs."
When output control is activated, the control unit in the F-CM AS-i Safety ST module is
switched on so that the F-CM AS-i Safety ST module generates an additional AS-i address
on the AS-i Bus. The associated value is output from the safe process image via this AS-
i address.
When output control is deactivated, the corresponding control unit in the
F-CM AS-i Safety ST module is switched off, and an AS-i slave is not emulated on the AS-
i bus.
AS-i address
Here, you set the AS-i address within the range of 1 to 31 that the F-CM AS-i Safety ST
module is to use for control of a safe AS-i output.
Uniqueness of the AS-i address on the AS-i bus
Carefully check the AS-i addresses for the control of the safe AS-i outputs. Ensure that the
assigned AS-i address exists only once on the AS-i bus. This is particularly important when
you are using multiple devices that can control safe AS-i outputs on the same AS-i bus. If
this is not observed, reliable shutdown of a safe output module is not guaranteed.
Note
Communication of the AS-i master with the AS-i address
The AS-i address of the control unit must be called by the AS-i master. Set up the
communication of the AS-i master in such a way that communication with the AS-i address
of the control unit functions properly.
