Example for writing a parameter via PROFIdrive
The following tables show the structure of the
WRITE
and
READ
services for
reman-
ent
writing of the fixed setpoint n0 (
P170
). The PROFIdrive service
Change parameter
is used for this purpose.
Send "WRITE parameter" request

Downward-compatible routing via
DS47
If DIP switch S1/1 = "OFF", the sys-
tem transfers the DS47 request with
the axis address 2 to the RS485 ad-
dress 254 of the MOVIMOT

.
•
Routing to 3 MOVIMOT

via DS47
If DIP switch S1/1 = "ON", the sys-
tem transfers the DS47 request with
the axis addresses 1 – 3 to the
RS485 addresses 1 – 3 of the
MOVIMOT
