This bit is used to activate Command mode. In Command
mode, no data is sent by the PLC to the Leuze end device via
the gateway. In Command mode, various bits that execute
corresponding commands depending on the selected Leuze
device can be set in the data- or parameter field. For further
information, see chapter 11.1.3 "Command mode".

A broadcast only functions with a multiNet network con-
nected via the MA 3x. If this bit is activated, the gateway
automatically adds the broadcast command "00B" before
the data. This is directed at all participants in the multiNet.
