Group Protection
The following protection features are implemented in a grouped configuration:
Power On
At power-on, all grouped units will have their outputs off (unless they have
been configured by the
*RCL0 command to be programmed on).
Configuration
check
At power on, the master unit will search for the slave units and compare the list
of slaves found with the previously stored configuration. If the lists match, nor-
mal operation continues. If the lists do not match, a Master/Slave Protection
(MSP) fault occurs and the outputs of all units remain off (see
Programming
Output Protection ). A message is placed in the Error Queue that lists the slave
units found and the slave units expected.
Com-
munications
check
If a master unit loses communication with any slave at any time, it will gen-
erate an MSP fault, which turns its own output off as well as the outputs of the
slaves that it can still communicate with. If a slave loses communication with
the master, the slave will also turn its output off.
