address of the Unit turns ON.
Network status, such as communications errors and duplicated Slave Unit node addresses, and
Slave Unit diagnostic results are detected by the Gateway Unit and displayed on the seven-segment display on the front panel and reflected in the Status Flags. (Communications mode 0 to 3
must be set.)
• Registration Table
A table of the Slave Units that should be participating at the nodes (including the node addresses
and corresponding Slave Unit model numbers) can be registered to verify the Slave Units actually
participating in the network and prevent unregistered Slave Units from participating in the network.
• Communications Status on Gateway Unit Seven-segment Display
The seven-segment display on the front of the Gateway Unit can be used to check communications status. The number of connected nodes is normally displayed, but if an error occurs, the
error code is displayed in hexadecimal and the error node address is displayed in decimal.
