two consecutive variables are transmitted.
Receiver settings
23.5.5 SCOMON
System Bus Communication On
This command triggers the reception of data or the cyclical transmission of previously
defined data objects.
The SCOM command initializes the data objects with the arguments RECEIVE (receiv-
ing data) or TRANSMIT CYCLIC (sending data cyclically).
In MOVIDRIVE
®
B, the command has been replaced by SCOMST. However, due to
downward compatibility, it can still be used with MOVIDRIVE
®
B.

ject with SCOM().
