Install, Wire, and Connect I/O
Install and Wire I/O Modules
For more
information...
Specific wiring information for each type of I/O module is contained in the product
data publication for that specific module. Therefore, refer to the appropriate product data
publication when you follow these steps.
a
Open each module locking bar and insert each I/O module into the slot
keyed for it. After you install each module group, secure the modules in
place with the module locking bar.
b
Snap each field wiring arm onto the the horizontal bar on the lower front
edge of the I/O chassis, then swing each arm up to connect on the front
edge of its module, pushing each arm until the locking tab holds it in place.
c
Remove the terminal cover from each wiring arm and connect the wires be
tween the I/O devices and the wiring arm terminals.
For more
information...
Trim and strip the wires as necessary, and make certain that each wire is firmly in place.
See chapter 3 of the PLC3 Programmable Controllers Installation and Operation Manual,
publication 17756.7.1, for more information.
d
Connect the power and ground wires.
e
Use tie wraps to gather the wires at each wiring arm, then bundle the
wires so the arms can pivot freely.
f
Replace the terminal covers and label the terminal status indicators appropriately.

Using 6200 Programming Software
For more
information...
For specific information about using 6200
programming software, see the PLC3
Programming Software Configuration Manual,
publication 62006.4.16.
Any AllenBradley or IBM and IBMcompatible machine can be used
as a programming device using 6200 or Application Interface (AI)
programming software.
Before you install the 6200 PLC3 programming software, you need
the following:
- 640 KBytes of RAM as base memory (expanded or extended
memory not required)
- 10 MBytes of disk space for storing files.
- AllenBradley DOS version 3.2x if you use a 1784T50 or
1784T45 programming terminal. If you use a 1784T47
programming terminal use DOS 4.01. If you use an IBM PC/XT,
IBM PCAT, or IBMcompatible programming terminal, use DOS
3.2, 3.3, 4.x, or 5.0.
- monochrome or color graphics monitor
- installed 1785KL, KTP, KT, KT2, KTK1 card
If your 1784T50 has DOS version 2.11 or earlier, you must upgrade
to the current version of AllenBradley DOS. The current version of
AllenBradley DOS is version 3.21.
Using AI Programming Software
Before you install the AI PLC3 programming software, you need
the following:
- IPM PC XT, AT or compatible computer with DOS 2.1 or later
For more
information...
For specific information about using AI
programming software, see the PLC3
Ladder Logistics Manual, publication
9399L3man06.01.89.
- monitor and graphics board. These display types are supported:
monochrome display system
CGA display system
EGA display system
VGA display system
- 640K RAM of system memory
- a floppy drive and a hard drive

Appendix
Troubleshooting and
Specifications
Powersupply Module
Indicators
If you don’t see the power-supply module indicators lit as specified
on page 3-2, use the following table to troubleshoot the problem.
Indicator:
Normal Operation:
If Not Lit:
AC ON
red
no ac power is being supplied to the unit
AC OK
green
an insufficient amount of ac power is being
supplied to the unit
DC OK
green
the supply's internal dc voltages are not in their
proper operating range
If the AC ON indicator is lit and either the AC OK or DC OK
indicators are not lit, you must shut down ac power (or toggle the
remote on/off for the PLC-3/10 chassis or lift and return the module
interlock bar on the PLC-3 chassis) to reset the supply. If this does
not clear the situation, you must troubleshoot the chassis using the
PLC-3 Family Controllers Installation and Operation Manual,
publication number 1775-6.7.1.
