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 points/registers including all remote input/output points 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)).
