If you set the Profibus address with rotary coding switches, then parameter p0918 can only be
read. The parameter shows the set address of the control unit. If the address is changed, it only
becomes active after POWER ON of the control module.

Requirements for communication via PROFIBUS
To further process the PZD data internally, the PROFIBUS master must always send a 1 in the
eleventh bit (bit 10) of the first control word (control by PLC). It is not sufficient to interconnect
parameter p854 permanently with a 1.
This also applies to slave-to-slave communication between multiple slaves (drive with DC
master as an excitation device). The eleventh bit (bit 10) must be preset to 1 in the first control
word of the master on the drive. This also applies when no other master control commands are
in use and slaves are communicating by direct slave-to-slave data exchange only.
