Profibus Output Data
The capability to reset, stop, and start the motor has been made available via the Profibus
Output data. Because polled output data is continuously written to the slave device, the
MM200 looks for a change in the value to execute any command.

Profibus DPV0-Diagnostics
The MM200 supports both slave mandatory (6 bytes system-wide standardized) and slave
specific extended diagnostic data. If the diagnostics are considered high priority, the PLC/
host program will be informed of the fault (alarm, trip, command, or message) and can call
a special error routine. When no extended diagnostic information is available and the
master initiates a diagnostics read, only the six standard slave mandatory bytes are read,
formatted as follows:
76 Pre Trip Motor Load F1
78 Pre Trip Current Unbalance F1
80 Pre Trip Ig F10
84 Reserved
