Note
1. The maximum distance between nodes depends on the connector and
cable processing methods.
2. With the token-bus method, the maximum number of nodes in an Optical
Bus System with optical bus nodes (i.e., model numbers ending in CLK11) is
32 (node addresses 1 to 32).
3. The data link table for the Board cannot be set using CX-Net in CX-Program-
mer. Use FinsGateway CLK data link settings, or Controller Link Support
Software (Ver. 2.00 or later).
4. The maximum number of words in an Optical System with optical bus nodes
(i.e., model numbers ending in CLK11) is 32,000 words.
