properties of the IO system.
STATION_NR IN UInt
• PROFINET IO device: Device number is applied in the
Network view from the properties of the IO device under
"Ethernet addresses".
• PROFIBUS slave: PROFIBUS address is applied in the
Network view from the properties of the PROFIBUS slave
under "PROFIBUS address".
DATA
IN_OUT

Pointer to the area where the name is written.
DONE OUT Bool The instruction executes successfully. Name of the module
transfers to the area at the DATA parameter.
BUSY OUT Bool Status parameter:
• 0: Execution of the instruction complete.
