Parameter channel via process data

All devices of the MOVI-C^® modular automation system offer the option of reading and writing parameters via acyclic services. The additional function "Parameter channel via process data" provides services for reading or writing device parameters irrespective of the fieldbus.

The device parameters are written to volatile memory, which means that the data is not saved permanently but will be lost when switching off the inverter. When the inverter is switched on again, the last parameterized value is available again.

You can activate the additional function in the parameter group [Basic settings] under "Functions used". If the additional function is activated, the parameter group [MOVIKIT^® parameter channel] is displayed under [Diagnostics]:

To use the parameter channel, the following information is required for the assignment of the process data:

• Index, subindex, and offset of the parameter
• Data to be sent or read

For a detailed list of available parameter channel process data, refer to the process output data and process input data in chapter Process data assignment.
