Parameter 22 — DeviceNet Voltage
This read only parameter is used for monitoring the DeviceNet voltage at the node. The
voltage reported via Parameter 22 may vary from actual voltage by up to 1V DC.
I/O Configuration
The I/O messaging is set up by the master device through client/server connections at
power-up. This device supports both Change-of-State (COS), cyclic, and Polled
I/O messaging connections. The default I/O size is one input byte and one output byte with
a polled I/O connection
The Output command is defined as follows:
