TwinSAFE groups
It makes sense to create TwinSAFE groups in cases where different machine safety zones are to realize, or
simply in order to separate the fault behavior. Within a group, a FB or connection error (here: alias device)
leads to a group error and therefore to switching off all outputs for this group. If an error output of an FB is
set, it will be forwarded as a logical 1 signal.
A group can be created by opening the context menu of the safety project and selecting
Add
and
New
Item...
.

Like the first group, the group of a subitem for the alias devices and a sal worksheet.

The instance path to the FB port to be linked can be specified, in order to exchange signals between the
groups. The instance path consists of the group name, the FB name and the FB port, each separated by a
dot. The input of the instance path is case-sensitive.
<group name>.<network name>.<FB name>.<FB port name>
Sample: TwinSafeGroup1.Network1.FBEstop1.EStopIn3
Alternatively,
Change Link
can be selected by opening the context menus next to the FB port.
