Description
Command mode
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".
Description
Broadcast
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.
Description
Address bits 0 .. 4
As with the broadcast command, individual devices in the
multiNet can also be addressed via the MA 3x . In this case,
the corresponding address of the device precedes the data
field telegram.
Description
New data
This bit is needed if several identical pieces of data are to be
sent in sequence.
