Starting up the inverter with INTERBUS (MCH42A)
Startup
Writing IPOS
plus®
variables /
parameters via
MOVILINK
®
The inverters offer special parameter access via the MOVILINK
®
parameter channel for
universal write access to all inverter data (parameters, IPOSIPOS
plus®
variables,
IPOS
plus®
program code, etc.). The following section illustrates the mechanism by
which, for example, IPOS
plus®
variables can be changed via the parameter channel.
The acyclic parameter channel can be used via index 8299 dec (206B hex).
Example
Writing the value 74565 of the IPOS
plus®
variable H0 = Index 11000 dec (2AF8 hex)
Value to be written = 74565 dec (0001 2345 hex)
You will receive the "Write_Confirmation" after this service has been sent. Once again,
you can use the return codes for evaluating a negative message.
