Note 1. When multiple Masters are used, allocate system numbers to them in se-
quence from 1, starting from the Master nearest the CPU. The system num-
bers have no special significance. Refer to 4-1 Word Allocation.
2. Up to two Expansion Masters can be connected to each Master.
3. When two Expansion Masters are used, set one as Unit 1 and the other as
Unit 2. The Slave address for Unit 2 can only be used for an 8-point or
16-point Slave. It cannot be used for a 4-point Slave.
4. Masters and Expansion Masters can be used in any combination, provided
that the maximum number of input and output points remains within the
range permitted for the CPU.
