Technical data
The group identifier makes it possible to distinguish the following 8 groups.
If no group identifier was specified at the HDB call for the global control job
(all bits set to "0"), the global control job is sent and executed by all DP
slaves capable of the Sync and/or freeze mode.
If the group identifier is not zero, the conditions for execution are as follows:
– Sync and/or freeze mode must be supported by the DP slave.
– At least one group of the global control job and of the group
identifier must match.
Slave name: Here, it is possible to assign up to 10 ASCII characters
long to the slave for documentation purposes.
