6.2.2 Parallel I/O and remote I/O
(1) I/O Points
● PIO Type
There should be 16 points of input and 16 points of output. (Change in number of used points not
available unlike field network)
By liking the PIO/SIO/SCON extension unit and PIO unit to PIO type SEL unit, it is available to
have PIO to use 144 points of input and 144 points of output at the maximum.
* Number of input and output points available to use when N units of PIO unit linked in line:
16 16 points x N units
● Field Network Type
By establishing the setting by I/O parameters, it is available to use 1,024 points of input and
1,024 points of output at the maximum. (Number of points to use should be indicated in 8 points
as one unit)
(2) Input and Output Port Assignment
• I/O used in PIO (except for PIO modules) and the field networks should be assigned to the
input ports from No. 0 to 299, output ports from No. 300 to 599, extension input ports from
No. 1,000 to 3,999 and extension output ports from No. 4,000 to 6,999.
• I/O used in PIO (PIO modules) should be assigned to the input ports from No. 0 to 299 and
output ports from No. 300 to 599.
• The priority in the automatic assignment should provide the order of the field network or PIO
module ⇒ PIO/SIO/SCON extension unit / PIO unit. Also, among PIO/SIO/SCON unit and
PIO unit, assignment should be given from units closer to SEL unit.
• In the fixed assignment, assignment for PIO/SIO/SCON extension unit and PIO unit should
be available in the input ports/extension input ports and output ports / extension output ports.
PIO module is available only of assignment to the input ports and output ports.
● Divided Assignment Feature
In response to the number of used I/O points in the field network, PIO/SIO/SCON extension
unit or PIO unit, assignment should be available divided to both ports of the input ports /
extension input ports and output ports / extension output ports.
