The inputs 1 to 3 of the DMI can be connected with switches
or pushbuttons to the local control of the motor to suit the
selected motor-starter function ( a section “Motor
starter”, Page 44). Input 4 and 5 are intended for connection
of the auxiliary switch, in order to recognise the switching
state of the circuit-breaker.

please note the Motorola coding format (Octet N: High-
Byte, Octet N+1: Low-Byte) used in PROFIBUS-DP for data
in WORD format. If the data processing format in your DP
master system deviates from this standard, and the DP
access commands do not automatically include a
conversion, it will be necessary to implement and perform
the conversion in your application program. Please refer to
the documentation of your DP master system.
