Communicate with Your Module
The module transmits SSI sensor data over the DeviceNet network. You exchange data
with the master through a polled, cyclic, or change-of-state connection.
The module does not support Bit-Strobe Command Response Messaging and the
Unconnected Message Manager (UCMM). If you are not familiar with these terms, see
the DeviceNet Specification for definitions at
http://www.odva.org .
The module produces and consumes data as follows:
I/O Connection Type Consumes Produces
Polled 2 bytes 10 bytes
Cyclic 2 bytes 10 bytes
Change-of-state 2 bytes 10 bytes
