To determine the I/O module numbers of JX2-I/O modules on the JX2 system
bus of the JC-120MC, proceed as follows:
Count the JX2-I/O modules left-to-right, starting with 2.
Leave out the intelligent JX2 slave modules and JetMoves.
Leave out the power supply module JX2-PS1.
Register numbers for JX2-I/O modules connected to the JX2 system bus of a
JC-120MC consist of the following elements:
2
0
0
0
Element
xx
I/O module number minus 2
z
Module register number
