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
The module produces and consumes data as follows:
