DeviceNet
The byte order for the
– word address,
– number of bytes and
– data word
can be specified in the communication parameters.
6.6.1.6 Fragmentation
By means of fragmentation, up to 384 bytes can be transferred in one
explicit message.
6.6.2 Poll I/O Connection
The Poll I/O Connection can be used for event-controlled exchange of
data between the master and the slave.
On account of the EDS data, the Poll I/O Connection is installed auto-
matically between the DeviceNet master and the operating device.
With this connection, 2 bytes are transferred cyclically from the control-
ler’s OUT area to the operating device and 5 bytes are transferred from
the operating device to the IN area of the controller.
6.6.2.1 Receive Data of the Operating Device (Consumed Data)
The Consumed Connection Size is 2 bytes.
See chapter „Byte Order“ on page 6-76.
