OVERVIEW
The Time Stamp is one out of a series of four modules. 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
* These modules are covered in a separate manual (Publication #0300169).
Each module will accept 32 single ended analog inputs. The inputs will be
divided into four groups of eight inputs each. Each group will have 15V
isolation to the other groups. Analog inputs within a group will have 0V of
isolation channel-to-channel. All inputs will have 500V ac isolation channelto-backplane.
The module has 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 feature
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.

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 ACI 052 00sc:
Step 1: Modsoft programming software must be updated so that the
140 ACI 052 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 modules 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 nine 4x level registers are used by the 140 ACI
052 00sc. After you have completed the runtime file installation, you can go
to the I/O Map screen and choose the 140 ACI 052 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
nine 4x level registers for use by the module. The architecture for this 32channel module is as follows:

programming manual for more information on the time of day clock usage.
☞ Note: The PLC time of day clock is read once at power up from registers 4x+1 through
4x+8. The modules internal clock chip is synchronized with the PLC clock at
this time. After power up, the module clock is synchronized with the PLC clock
at least once a day. (See Section 4.2 for more details.)
The ACI 052 00sc multiplexes 32 channels of data into four groups
of eight channels. Each group can be selected through the 4x
Configuration Word or can automatically sequence through all four
groups channels.

❑ 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:
8
Installation Instructions
32-Channel Analog Input Module
Quantum Series 140 ACI 052 00sc
Once at power up only
Every 1 min
Every 10 min [default]
Every 30 min
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 Hz 1,420 msec
50 Hz 397 msec
60 Hz 260 msec
1000 Hz 45 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 Hz [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

Installation Instructions
32-Channel Analog Input Module
Quantum Series 140 ACI 052 00sc
+ Note: The modules format selection must be compatible with the register format
selected in Modsoft.
❑ Input Range: Module must support current input to select voltage or
current. One of the following input ranges may be selected for each
of the four groups of eight channels:
Range: -10 to +10 V [default Voltage 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. The second channels output is 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.
☞ 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

❑ Alarm Enable: The second zoom screen, shown in figure 2.2, allows
the user to enable or disable alarms. Alarms are disabled by default.
If enabled, the limits defined by the user are used to monitor input
signals for alarm conditions and any alarm events will be captured
along with a time stamp for that event. Otherwise, no alarms will be
captured.
(425) 746-9481
When an alarm occurs, the appropriate channel error flag for the
appropriate group is set in the status word (4x bits 1 through 8). The
user may then read each alarm in that group (up to 4 channels) by
setting the mode select bits to the Read Time Stamp Output mode (see
Chapter 4.1). If no alarm exists, all data will be 0.
When in the Read Time Stamp Output mode, the group select meaning
is different than it is in Read data and Read Channel Status modes.
Only two channels of information is available when reading time
stamps. The time stamp read channel select settings are as follows
(see Section 4.1 for more detail):

3x+6 1 .. 16: Chan N+1: Timestamp: Hour/Min BCD.
3x+7 1 .. 16: Chan N+1: Timestamp: Month/Day BCD.
* The Sub Seconds Count (SSC) field is not an even time period count such as seconds. Instead, it is a
counter which increments whenever an alarm occurs at the same Hour/Min/Sec setting the previous alarm.
This field insures unique time stamps for alarms detected within the same second.
❑ Alarm Timestamp Update Mode: The alarm timestamp update mode
may be set to scrolling or latched. In scrolling mode any new events
will be captured and the time stamp will reflect the last time at which
an alarm existed for that channel pair. If the channel pair moves out
of an alarm condition, then the time stamp would reflect the exact
time that this occured. In latched mode only the first event will be
captured and saved until the alarm is cleared. In either case, the alarm
will be cleared by reading it.
☞ Note: Time Stamp data is stored in RAM and will be lost if system power is lost for any reason.
❑ Alarm Limits: The second and third zoom screens (figured 2.2 and
2.3) allow the user to define sixteen unique alarm limits. Each alarm
is defined with a high and low setpoint. Each limit applies to two
adjacent channel The data format for the alarm must match the format
for that channels group as assigned in the first zoom screen. For
example, if group 1 configured as a -10V to +10V range and DVM
format, a low of -5000 and a high of 5000 will trigger alarms at voltages
12
less than or equal to -5V and voltages above +5V respectively.
