Parameterization Of A Devicenet Device - Beckhoff EtherCAT EL6752 Documentation

Parameterization and commissioning
Bit strobe
The IO mode bit strobe involves an 8-byte command from the master to the slaves. For each possible
address/MAC ID (DeviceNet address space: 64) 1 bit of user data is allocated. The maximum length of the
response message from the slave is 8 bytes. It is sent to the master immediately when the bit strobe
command is received.
After selection of the bit strobe mode the input data must be configured accordingly. Any data type can be
selected (see polling/ COS / cyclic). The data length is converted to a byte stream according to the
DeviceNet specification and displayed in the tab for the bit strobe connection:
Fig. 58: "Connection" tab showing connection type "Bit Strobe" and input and output parameters
Maximum data length
The maximum input data length is 8 bytes. The output data length is fixed.
Since the communication settings are specified through the master no further settings are possible.
