1. In systems that combine Optical Bus Controller Link Units/Boards (model
numbers ending with CLK11) with other Units/Boards, the max. number of
nodes and words are as follows:
Method
Manual Optical Bus Units/Boards:
Up to 32 nodes (with node addresses 1 to 32) can be data linked
and the max. number of data link words is 32,000 words/node.
Automatic All Units/Boards:
Up to 32 nodes (with node addresses 1 to 32) can be data linked
and the max. number of data link words is 32,000 words/node.
2. If Controller Link Units are used in duplex operation, the maximum number
of active nodes is equal to the following:
62 − Number of standby Units
Description
12,000 max. (pre-Ver. 1.2)
