I/O Communications
The I/O communications function uses DeviceNet I/O connections to exchange data
between DeviceNet devices connected on the communications path and the MP900 Machine
Controller.
The CP-717 Engineering Tool is used to allocate I/O registers in the Controller's CPU for I/
O communications.
Message Communications
The message communications function sends explicit messages that read the DeviceNet
device names or serial numbers and write parameters for DeviceNet devices.
The MSG-SND function is used for message communications.
