Example for writ-
ing a parameter
via MOVILINK
®
The following tables show the an example of the structure of the WRITE and READ ser-
vices for volatile writing of the value 12345 to the IPOS
plus®
variable H0 of a
MOVIDRIVE
®
B with SBus address 1, which is connected to the CAN 1 system bus
(X33) of DHR41B (parameter index 11000). The MOVILINK
®
service WRITE parameter
volatile is used for this purpose.
Send 'WRITE parameter volatile' request
The following table shows the WRITE.request user data for MOVILINK
®
"Write para-
meters volatile.
After sending this WRITE.request, the WRITE.response is received. If there was no sta-
tus conflict in processing the parameter channel, a positive WRITE.response occurs.
Otherwise, the status fault is listed in
Error_code_1 .
