In OPERATE mode the PROFIBUS Master Unit
will parameterize all allocated slave devices,
and commence I/O Data-Exchange.
See Note 1 and 2.
FALSE:
If the PROFIBUS Master Unit has entered the
OPERATE mode, the Unit will change this bit to
FALSE again.
FALSETRUE:
Switches the Unit to the STOP mode. If the Unit

In STOP mode, the Unit will be online, con-

with its slave devices.
See Note 1 and 2.
FALSE:
If the PROFIBUS Master Unit has entered the
STOP mode, the Unit will change this bit to
FALSE again.
FALSETRUE:
Switches the Unit to the CLEAR mode. If the
Unit is already in this mode, no action will be
taken. In CLEAR mode the PROFIBUS Master
Unit will parameterize all allocated slave
devices, and it will read the input data of the
slave devices, but it will send zeros or empty
output messages to slave devices.
