Systems with HSCI interface:
 Use the POWEROFF setting for shutdown, or use Module 9279 – mode 2 to 
shut down the control.
 Set the parameter MP_powerOffDevice:
Every external PL in the HSCI system has a unique bus address. To define 
the PLC output to be set, you must specify the bus address of the affected 
system PL or the UEC 11x in parameter MP_powerOffDevice. The bus 
address can be determined with the BUS DIAGNOSIS, for example:
 Set the parameter MP_powerOffSlot = 0.
 Use MP_powerOffPort to define the desired output terminal.
Use the tables on the next page to determine the value for parameter 
MP_powerOffPort.
The following PLC outputs can be set automatically after shutdown:
 Freely available PLC outputs at X9 of a PL 62xx (system PL)
 PLC outputs at X6 of a UEC 11x
The output terminals that can be used are listed in the tables on the 
following pages.
