OVERVIEW
Throughout this installation and operation guide, unless reference is being made to one specific version of the module, the designation 140 AxI 05x 00sc will be used for generic reference purposes. The 140 AxI 05x 00sc consists of a series of four analog input modules, each with 32 channels of input. The differentiation between the four different modules is shown in the table below.
140 ACI 050 00sc current only
140 AVI 050 00sc voltage only 140 ACI 051 00sc current or voltage combination *140 ACI 052 00sc current or voltage combination with time and date stamping * The 140 ACI 052 00sc Time Stamp option is covered in a separate manual.
Each module will accept 32 single ended analog inputs. The inputs are divided into four groups of eight inputs each. Each group has 15V isolation to the other groups. Analog inputs within a group has 0V of isolation channel-to-channel. All inputs have 500V ac isolation channel­to-backplane.
These modules have been designed for projects that include large quanti­ties of analog inputs. Process control and data acquisition applications for industries such as utilities, waste water, oil and gas, food and beverage, and building automation are ideally suited for this module. The time and date stamp version of the module is perfect for remote terminal unit (RTU) applications or for supervisory control and data acquisition (SCADA) applications requiring programmable alarm levels.
Input channels include over voltage circuit protection, over and under range detection and active notch filtering. The voltage mode of the module handles four different voltage ranges and the current mode handles two current ranges. You can configure the module to provide data in one of four data formats. Set up of the module is very simple through the use of configuration and status registers using Concept, Modsoft or Taylor programming software.

1.1 Inputs
The module can be purchased as current only, voltage only, current or voltage combination, or as a current or voltage combination with a time stamp option. The 32 channels are separated into four groups of eight. Each group can be configured for a different voltage or current range. The ranges available are as follows:
Current Ranges
• 4-20 mA, 0-20 mA
Voltage Ranges:
• ±10VDC, 0-10VDC, 0-5VDC, 1-5VD
The module can provide data to the PLC in the following formats:
• 12 bit (0 to 4095)
• signed 15 bit (-32768 to +32767)
• unsigned 16 bit (0 to 65535)
• DVM (0 to 10000)

MODULE SETUP FOR MODSOFT
2.1 General Information
Six steps must be performed in order to fully configure the Quantum system in preparation for using the AxI 05x 00sc:
Step 1: Modsoft programming software must be updated so that the
140 AxI 05x 00sc is recognized in the software (see Section 2.2).
Step 2: Select the appropriate slot location using the Modsoft I/O map.
Choose the first 3x and 4x level registers to be used in the system for the module’s data, configuration and status informa­tion (see Section 2.3).
Step 3: Zoom screens for the module must be set to match application
requirements (see Section 2.4).
Step 4: The 4x configuration register must be set to meet application
requirements (see Section 4.1).
Step 5: Module status information is available to you. The various
options must be understood and chosen to meet your application requirements (see Section 4.2 and Section 4.3).
Step 6: Ladder rungs must be written to demultiplex the incoming 8 data
registers to 32 user selected data registers (see Section 6.3).

2.2 Installation of new run time files
If you are using the Modsoft programming software version 2.4 or 2.5, it is necessary to update the following runtime files in order for Modsoft to recognize your module. Versions prior to 2.4 are not supported. Version
2.6 and newer already include these updates.
LMSFDT.SYS Zoom screens GCNFTCOP.SYS I/O Map module definitions
QUANTUM.SYS Quantum help screens
This may be accomplished by first identifying the pathname where you have installed your Modsoft programming software and the drive letter of the floppy drive from which you intend to install. A typical pathname assuming installation of the C: drive is as follows:
C:\MODSOFT
The new runtime files required to use all versions of this module are supplied on the 3.5 inch MSDOS formatted floppy disk titled:
“Quantum Runtime Files,” Spectrum Controls, Inc Part Number: 20500121-xx
To install these files, operate your PC in MSDOS mode, perform the following command:
C:>\COPY A:*.SYS C:\MODSOFT\RUNTIME
+ Note: This assumes you are installing from drive A: and that you have previously installed
Modsoft in the directory C:\MODSOFT . If not, you must make the appropriate substitutions.
2.3 General information on data register usage and terminology:
A total of nine 3x level and one 4x level registers are used by the 140 AxI 05x 00sc. After you have completed the runtime file installation, you can go to the I/O Map screen and choose the 140 AxI 05x 00sc by selecting the desired slot, pressing <Shift + ?> which will display the modules available for configuration into that slot. For module specific help, press <ALT + H>. After selecting the module, you must set the first 3x and 4x level registers to be used. This will then automatically capture nine consecutive 3x level and one 4x level register for use by the module. The architecture for this 32-channel module is as follows:

Calibration rate: The Quantum module performs an on board system calibration at power up. The system calibration corrects for temperature drift of the Analog to Digital Convertor (ADC) and related circuitry. System calibration can be performed periodically based on the calibration rate selected below. This can affect the update time for the module. For installations where the ambient temperature surrounding the I/O rack can change relatively quickly, the user might consider going to a more frequent calibration selection in order to improve the accuracy of the reading being taken. The autocalibration schedule rate may be selected from the following:
Once at power up only Every 1 min Every 10 min [default] Every 30 min
8
Selecting an autocalibration schedule rate is an exercise in tradeoffs. Performing autocalibration more frequently may result in greater accu­racy due to variations caused by environmental factors such as tempera­ture. This accuracy has a cost in the burden imposed by performing the calibration. The calibration time is a function of the filter frequency. Calibration times are listed below. The system cannot update the channel data while performing calibration. In addition, if multiple filter frequencies are selected, calibrations for each frequency and the execution time is cumulative. The worst case calibration time is when all filter frequencies are enabled (10, 50, 60 and 1000 Hz). The time is then the total for all four times listed below. Also, note that the channel enables have no effect on the auto calibration feature. If a filter frequency is enabled via the zoom screens, then the autocalibration is performed for the frequency.
10 Hz1,420 msec 50 Hz 397 msec 60 Hz260 msec 1000 Hz45 msec
Filter Frequency Selection: The Analog-to-Digital Conversion
performs a filter function on the input signal. One of the follow­ing filter frequencies may be selected for each of the four groups of eight channels:
Filter: 10 Hz
50 Hz 60 H z [default]
1000 Hz
Input data format: One of the following data formats may be
selected for each of the four groups of eight channels:
Format: 16-bit Format
Voltmeter [default] 12-bit Format 15-bit plus sign Format
Note: The module’s format selection must be compatible with the register format selected
in Modsoft.
9
Input Range: Depending on the module that you have purchased,
one of the following input ranges may be selected for each of the four groups of eight channels:
Range: -10 to +10 V [default V oltage or V/I Modules]
1 to +5V 0 to +5V 0 to +10V 4 to 20mA [default Current Modules] 0 to 20mA
Differential mode: One of the following acquisition modes may
be selected for each of the four groups of eight channels. Differ­ential mode calculates the difference between two consecutive channel inputs and provides the data to the register assigned for the first channel in the pair. When differential mode is enabled, the second channel’s output will be zero. The data acquisition between the two channels is not synchronized so common mode noise on the signal pair may not be fully removed, however DC offsets should be compensated for correctly.
10
Note: The channel pairs are not being updated simultaneously , this could lead to an
error in the actual differential value that is calculated. See figure 2.1 Differential Mode: Disabled [default]
