Arrangement of I/O Points
No matter the MPU with how many points you are using, the input point No. of the first connected extension unit has to
start from X20 and output point No. from Y20. The MPU is able to connect to maximum 14 digital extension units. The
connection of MPU and extension units is demonstrated in the figure below.
MPU EXT1 EXT2 EXT3 EXT4
The 3
extension module 06SN11R will be regarded as 8-point output. The 2 output points of bigger No. will have no
rd
actual corresponding output points.
The 4
extension module 08SP11R will be regarded as 8-point input/8-point output. The 4 input points and 4 output
th
points of bigger No. will have no actual corresponding input/output points. Therefore, it is suggested that they placed in
the end of the series connection to make the No. of I/I points continuous.
Input Point Wiring & Specification
There are two types of signals at input points, DC and AC, and there are two types of DC inputs, Sink and Source. The
wiring is as follows.
