parameter response
The two following tables show the Read.req user data with the positive response data
of the parameter setting request. For example, the parameter value for index 8300 (firm-
ware version) is returned.
Example for writing
a parameter via
MOVILINK
®
The following tables show as an example the structure of the write and read services for
volatile writing of the value 12345 to the H0 variable (parameter index 11000). The
MOVILINK
®
service Write Parameter volatile is used for this purpose.
Send "Write parameter volatile" order
After sending this Write.request , the Write.response is received. If there was no status
conflict in processing the parameter channel, a positive Write.response is sent. Other-
wise, the status fault is located in Error_code_1 .
