About this Manual:
This manual describes the installation and operation of Analog Input Modules
and Analog Output Modules for the C120, C500, C1000H, and C2000H SYS-
MAC C-series PLCs. These Modules are classified as Special I/O Modules
and include the following:
Analog Input Modules
The Analog Input Modules convert analog inputs to digital (binary) form. The
type and range of input as well as the digital format depend on the model.
Some models provide additional features such as peak values, means, or
scaling.

1--1 IntroductionAnalog I/O Modules are used to interface the digital operation of the PLC
with analog I/O field devices. Analog Input Modules convert analog signal
from input devices to digital PLC data. Analog Output Modules convert digital
PLC data to analog signals for output devices.
1--2 Basic Configuration
This diagram shows some of the possible field devices for the Analog I/O
Modules. Any I/O device may be used as long as its voltage/current require-
ments fall within the specified ranges (see
Appendix B ).
The I/O device connected to the Analog I/O Module will often serve as an
interface for another device, e.g., a preamplifier may interface a pressure
gauge to increase the signal level to Analog Input Module requirements; a
regulator may interface a heating system to control temperature.

1--4 Allocated Words
Each Analog I/O Module is allocated either two or four words. This section
specifies only the actual number of words allocated to the Modules; use of
these words is dealt with in
Section 4 Operation .
The first word allocated to the Module is designated as “n” in this manual.
Remaining words, which are always consecutive, are designated as n+1,
n+2, etc. Refer to you PLC’s
Operation Manual for details on how words are
allocated to Modules.

different depending on this switch setting. Refer to later sections of this man-
ual for details.

Module. There are no switch settings required on the other Analog I/O Modules.

2--1 AD101 Analog Input Modules
There are two settings necessary for this Module: the operation mode and
the input ranges (offset and gain) for each input point
Select either two-word or four-word operation. If you select two-word opera-
tion, data is transferred between the Analog Input Module and PLC using the
I/O READ and I/O WRITE instructions, WRIT(87) and READ(88). If you se-
lect four-word operation, data is transferred between the Analog Input Mod-
ule and PLC via the MOVE instruction, MOV(21).
Use of WRIT(87) and READ(88) will simplify programming and shorten the
time required to access analog input data.
The switch for this setting is on the back of the Module and will not be acces-
sible while the Module is mounted to a Rack. Be sure to set this switch before
mounting the Module to the PLC. The setting of the switch is read when the
PLC power is turned ON.
Caution Only the following C120 and C500 CPUs are equipped with WRIT(87) and
READ(88), which are required for two-word operation: 3G2C4-SC023-E and
3G2C3-CPU11-EV1 With all other C120 and C500 CPUs, you must use
four-word operation. These instructions are supported by all C1000H and
C2000H CPUs. Two-word operation is not possible if the Analog I/O Module
is mounted to a Slave Rack in a Remote I/O System, regardless of the CPU.
Four-word operation
Two-word operation
Back of Module
Each input point is set with an offset (minimum) of 1 V (4 mA) and a gain
(maximum) of 5 V ( 20 mA) at the factory. Use the following procedure to
change these settings if necessary. The offset and gain can be set to any-
where between 0 and 10 V (0 and 20 mA) as long as the gain is greater than
the offset. (Refer to
Section 3 Operation for details on AD conversion.)
Caution If an offset is set below 0 V (0 mA), the binary-converted value will be locked
at 000hex; if a gain is set above 10 V (20 mA), the binary-converted value will
be locked at FFFhex for voltage inputs, but not for current inputs.

1, 2, 3... 1. First set up a power source and meter. For voltage inputs, you will need
a 0 to 10 VDC supply and a DC voltmeter. For current input, you will
need a 0 to 20 mA DC supply and a DC ammeter. Mount the Module to
the PLC and connect the power source and meter. Voltage and current
specifications can be set independently for each input point. The follow-
ing examples illustrate how to wire the input points

Use to read in the desired values.
3. Remove the front panel of the Module with flat-blade screwdriver. Pins 1
through 8 on SW 1 represent input points 1 through 8 respectively. Turn
ON the pin for the input point to be set and make sure all the other pins
are OFF. First we will set input point 1.
OFF ON
4. The offset is the lowest voltage or current that will be input. The Module
will convert this value to 000 hexadecimal. Apply the desired offset to
the terminals of input point 1. Flip SW 2 down to read in as O V or mA
the current or voltage currently being applied to the input terminals.
This input value will be stored as the offset, i.e., as zero.

6. Continue on in this way to set the offset and gain for input points 2
through 8. Make sure you turn OFF each pin of SW 1 before you turn
ON the next pin. Never allow more than one pin of SW 1 to be ON si-
multaneously. After you are finished setting all the input points, re-at-
tach the front panel to the Module.

The output range must be set for each input point using the DIP switches on
the back of the Module. Each input point is set to 1 to 5 V at the factory, but
double check the settings before use. Be sure to set these switches before
mounting the Module, as they will not be accessible while the Module is
mounted.

3--1--2 Wiring
Use shielded twisted-pair cable for external connections.
Connect the positive and negative terminals of any unused input points to the
shield terminal.
Use separate power supplies for input points 1 and 2 whenever possible.
When using separate power supplies, always connect the negative input ter-
minal to the shield line; failure to do so will produce several percent of error
in the converted data.
Incorrect wiring will produce inaccuracy in converted data. Use the proper
wiring diagram and wire with care.
