1.2 The I/O Menu

Accessing the I/O

There are three ways to access the status of the I/O on the CP-6 series machines:

a. Through the machine menus

Each input and output has its own separate name and address which may be seen by

pressing [SET], [MANUAL] and [I/O].

b. Direct I/O Entry

The alternate method of entering the I/O, called direct I/O entry, may also be initiated

by:

1. Turning the machine OFF.

2. Hold the black F1 key down.

3. Press the POWER ON key.

4. Keep the F1 key held down until the first color (I/O) menu comes up.

c. Visual Observation of the PLC LEDs.

This procedure puts the operator directly into the I/O. The main purpose of this mode is

for troubleshooting. The machine should be turned off after troubleshooting is

completed.

1.3 Using the I/O Map

Using the I/O map is quite simple. Once in the I/O menu, the operator has a choice to

choose the Input side to work with, or the Output side. Only one side may be accessed

at a time (although both are displayed on the screen at the same time). When a side is

selected, the [PAGE +] and [PAGE -] keys become active. Locate the desired port with

these keys. The UP and DOWN arrow keys may also be used to move the cursor one

port location at a time.

The Input side only reports the current input state of the port. If the the input terminal is

connected to DC ground, then a green ‘0’ (active) will appear in the I/O MAP for that

port address. Otherwise, a yellow ‘X’ (not active) will appear for that port. If the cursor

is on the port and the port is active, then the buzzer will be turned ON.

The Output side allows the operator to change the state of the port with the ON/OFF

key. Pressing this key will toggle the current state of the output port. A yellow ‘X’

means ‘not active’ and a green ‘0’ means ‘active.’

1.4 Reading the I/O Map List

A description of the I/O map fields is given below:

LED # PORT# STATE DISPLAY PAGE DESCRIPTION

LED #

Refers to the LED #

on the various I/O

modules of the PLC's.

It is also the Terminal

number that the wire

carrying the input

signal is connected to.

the wire number

of the wire carry-

ing the input signal.

State

The state of the I/O

signal after power-

ing on the machine,

Zero-setting the machine

and pressing AUTO

and no alarms indicated.

Display

Refers to what is displayed by

the machine as the formal

name of the port.
