Item Specifications
Program Memory Capacity 16K words (1 word: 24 bits)
Maximum I/O Points 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 Modules max.
The total number of remote I/O points and registers 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: Max. 4 Rack
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 remote and local I/O points and registers must meet the above
conditions 1) and 2).
Maximum Points 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)).
