Number and Function of External I/O [X] / [Y]
z
Addressing for I/O points (Octal):
X0 ~ X7, X10 ~ X17, X20 ~ X27......, X70 ~ X77, X100 ~ X107...
Y0 ~ Y7, Y10 ~ Y17, Y20 ~ Y27......, Y70 ~ Y77, Y100 ~ Y107...
z
I/O point addressing:
The expansion I/O are numbered in octal and are used in multiples of 8. I/O points less than 8
will still be regarded as 8. The expandable I/O capabilities can reach 256 input points with 16
output points or 256 output points with 16 input points.
