Polling node address Startup node address
Each node address is displayed in 2-digit BCD.
The numbers in the squares are node addresses.
The corresponding node participation status is as follows:
0: Not participating in network
1: Participating in network

When CS1W-CLK21-V1 and CJ1W-CLK21-V1 Units are
used and the Wired Network 62 Node Enable Bit in the DM
Parameter Area software switches is ON, the network
participation status of nodes 33 to 62 will be returned in
words +4 and +5.
