A running bus can, of course, also be stopped with the standard command and re-configured!
The function AsIOAccWrite() from the library AsIOAcc must now be used to write the respective data to all registers
Vendor1Cfg to Vendor16Cfg and Device1Cfg to Device16Cfg. All vendor and device registers that are not being
used must be set to zero. This does not cause a change in the status registers.
To save the data in remanent memory, the function AsIOAccWrite() from the library AsIOAcc must be used to write
to the two registers in the specified order.

acyclic commands.
Minimum cycle time
200 µs
