Connecting Pulse I/O Modules to the CPU Unit

Up to two Pulse I/O Modules can be connected to a CJ2M CPU Unit.
They must be connected immediately to the left of the CPU Unit.
The Pulse I/O Module closest to the CPU Unit is Pulse I/O Module 0 and the other one is Pulse I/O
Module 1.

Pulse I/O Module Detection

The CPU Unit will automatically detect the Pulse I/O Modules that are connected when the power sup-
ply is turned ON. The Pulse I/O Modules are therefore not registered in the I/O tables.
An error will not occur when power is turned ON even if there is a different number of Pulse I/O Modules
connected or different models of Pulse I/O Modules connected.
