DeviceNet IO modes
The EL6752-0010 supports the DeviceNet modes cyclic polling, change of state / cyclic and bit strobe. The
IO modes can be selected according to the DeviceNet specification.
The DeviceNet IO mode cyclic polling is the default selection for the EL6752-0010:
IO mode
Polling
Change of State
Cyclic
Bit strobe
Polling / Change of State (COS) / Cyclic
The cyclic polling mode is characterized by cyclic polling of the IO data by the master. The change of state
mode is characterized by event-oriented sending of IO data. In cyclic mode the IO data are sent cyclically
based on the communication parameters configured by the master. Since the communication settings are
specified through the master no further settings are possible. Further information on the modes can be found
in section DeviceNet Communication. The settings are identical for these modes.
The input and output data lengths are pre-initialized to 8 byte each:
