B3.2 Substation Configuration
In a Fiber-optic FA-bus Type 2 system, a user can split a subunit into multiple
substations, as shown in Figure B3.1, “Substation Configuration Example”. Logically, a
subunit consists of 16 slots. Up to 7 subunits are allowed in a system.

Figure B3.2 Patterns for Splitting Subunits
When pattern (3) is used, for example, up to 7 subunits can be connected, providing a
maximum of 21 stations.
A 32-station system (maximum configurable system) can be configured by combining 6
sets of pattern (5) and 1 set of pattern (6). In pattern (6), only one module can be
installed per substation.
