EL675258 Version: 2.1
Selection of the IO mode and the general configuration must then be carried out manually.
DeviceNet IO modes
For DeviceNet devices the EL6752 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:
IO mode Input data length / bytes Output data length / bytes
Polling 0 - 255 0 - 255
Change of State 0 - 255 0 - 255
Cyclic 0 - 255 0 - 255
Bit strobe 1 bit 0-8
Total of all IO data max. xxx bytes max. xxx bytes
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. The settings are identical for these
modes.
The input and output data lengths must be supplemented according to the device configuration:

Input or output data must be appended depending on the device configuration. Any data type can be
selected:
