Acyclical communication

For each fieldbus, MOVIDRIVE
variables, cam disks and the IPOS
ferred to as parameter channel or parameter service). An IPOS
eter settings are not required.
Data in the inverter is accessed via index addressing. For the index of a parameter, refer
to the parameter list or press CTRL-F1 in the input field of the parameter.
The index of a H-variable is the number of the variable plus 11000 (for example, H34
has the index 11034).

Special features of communication via SBus

If you use the SBus instead of a fieldbus as the data source for control and setpoint val-
ues, the same functionality is available as for the fieldbus, but cyclical process data is
read or written in a time slice of 1 ms.
Furthermore, it is possible to receive or send additional cyclical or acyclical messages
via an SBus with an IPOS
SCOM in the sections "Compiler Functions" and "Assembler Commands".
