Maximum I/O Points/Registers 1) Digital I/O points: 1,024 points max. (1 point: 1 bit)
2) I/O registers: 512 registers max. (1 register: 16 bits)
3) Local I/O:
D Number of channels: 1
D Number of Racks: 4 Racks max. including CPU Rack.
D Number of mountable I/O Modules: 54 max.
The total number of points/registers including all remote input/output points must
meet the above conditions 1) and 2).
4) Remote I/O:
D Number of channels: 2
D Number of stations per channel: 15
D Number of Racks per channel: 4 Racks max.
D Number of I/O points per station:
(Digital input points ÷ 8) + (Input registers x 2) ≤ 512 bytes
(Digital output points ÷ 8) + (Output registers x 2) ≤ 512 bytes
The total number of points/registers including all remote input/output points must
meet the above conditions 1 and 2.
Maximum Number of Coils and
Relays
1) When the number of data registers is the initial value, the following condition must
be met:
(Number of coils) + (Number of relays) ≤ 65,520
2) The maximum value of each reference can be freely set within the above limit from
the Programming Panel (Unit: point (1 point = 1 bit)).
