Operation With Acknowledgment Pulse

For operation of the PROFIBUS ILM with acknowledgment pulses, a manual setting must made during
configuration. Operation with acknowledgment pulse is only intended for the use of point-to-point links between
two PROFIBUS ILMs.
Note
If a point-to-multipoint topology is being used, this mechanism must be deactivated otherwise problems can
occur on the bus.
