If invalid module combinations are configured within a SlotGroup, then

  • the specification is rejected and
  • the following diagnostic message is output: 0x81B5 “Invalid module and slot configuration”.

Please refer to the Overview of slots and ModuleGroups.

PWM (Real) | ModuleIdent 0x10098C

Notice

Specifying invalid duty cycle and frequency values

If the specified duty cycle or frequency value is outside the valid output range, then

  • the specification is rejected,
  • a diagnostic message is output:
    0x461B “Slot group n: Invalid duty cycle written”,
    0x461A “Slot Group n Invalid frequency/period written”,
  • the maximum permissible value is output.

For more information, see the chaptersChanging the duty cycle | “PWM duty cycle” process data value and “Changing the output frequency | “PWM Frequency” process data value”.

PWM (Integer) | ModuleIdent 0x8098C, 0x38098C

Notice

Specifying invalid period values

If the specified period values are outside the valid output range

  • the specification is rejected,
  • a diagnostic message is output:
    0x461A “Slot Group n: Invalid frequency/period written”,
  • the maximum permissible value is output.
