35.1.10 Rule for creating branch circuit
Limitation in the number of branch circuits
In one parallel branch or selective branch, up to eight circuits can be provided.
When there are many parallel branches and selective branches, however, the total number of circuits per
initial state is limited to 16 or less.
It is not permitted to execute transfer or reset from a recombination line or state relay before recombination to
a branch state relay.
Make sure to provide a dummy state, then execute transfer or reset from a branch line to a separate state
relay.
