Note 1. To circulate a token among the nodes connected to the network, match the
uppermost three digits of the IP address, the sub-net mask, and the broad-
cast type to those of the other connected nodes.
2. If either Unit rear rotary SW + node No. or Unit rear rotary SW is set as the
IP address setting method for the CS1W-FLN22 or CJ1W-FLN22, a setting
error will occur (HER indicator will light). Set the IP address setting method
to either
192.168.250 + node No. (default) or Setup Area .
3. The baud rate setting is supported by the CS1W-FLN22 and CJ1W-FLN22
only. The setting cannot be made for the CS1W-FLN02 or CS1W-FLN12,
which always communicate at 10 Mbps.
4. Select Option - Switch Settings - Hex from the Main Menu. The IP ad-
dress and subnet mask will be displayed in hexadecimal, and hexadecimal
input will be possible.
5. If communications are set to connect via the network and storage in the
PLC is set to use the FA link allocation table storage method, the maximum
number of nodes that can be registered in other node areas is 50.
