General Information 1

Overview

This manual will help you install and maintain PointScan/100 I/O modules. In summary, wiring for power,
communications and I/O is connected to each module’s base. Then, setup choices are entered using the
IO Toolkit software and the system will be ready to run. Shown below are some typical system
configurations using PointScan/100 I/O:

General Specifications

These general specifications apply to all PointScan/100 I/O modules. More detailed product specifications
may be found in the online help system of the IO Toolkit configuration software.

General Information 1-1

I/O Module Components

A PointScan/100 Series I/O module consists of a base assembly and a removable logic module. All base
assemblies have a hinged door that is accessible when the logic module is removed. In 4-20 mA analog
input modules (PointScan/102, /104, /108, and /130) the hinged door provides access to jumpers and/or 100
ohm replaceable shunts.

A logic module may be removed by lightly squeezing the top and bottom locking tabs and pulling the logic
module straight out. To reinstall, insert the logic module into the base and press firmly until it snaps into
place. The logic module is fully seated when the innermost row of ventilation slots are just covered by the
top surface of the base cover.

DC Power Overview

PointScan/100 modules can be powered from the same DC source that is used to power your I/O devices.
No separate power supply is required. Typically, 10 to 30 VDC power is applied to terminals 24 and 25 on
the base of each module.

The PointScan/443 is used to power up to seven PointScan modules of any type, instrumentation loops, and
other devices. It operates on 85-264 VAC (47-63 Hz) or 120-370 VDC and outputs 24 VDC at up to 1 A.
Refer to the figure below for the proper power connections.

1-2 General Information

9-12-01

PointScan/100 User’s Manual

DC Power Wiring PointScan/443

PointScan/442 gateways, and user instrumentation loops may be powered from the PointScan/443 power
supply. The PointScan/443 supplies 24 volts DC at a maximum of two amps.

DC Power Wiring (User DC Source)

PointScan/442 gateways, and user instrumentation loops may be powered from a single DC source. The
user DC power source must be between 18 to 30 volts.

Current Requirements

To calculate the current requirements, add the wattage required for the I/O modules in use, then divide the
total wattage by the DC power source voltage. Then add any current needed for user instrumentation loops.

PointScan/100 LEDs

Every PointScan/100 module has a number of LEDs. These LEDs can be useful for system diagnostics.
These LEDs can be observed in the following states:

I/O Module Status LED

On, with a quick “OFF” BLINK [Long Blink](1.9 seconds ON, .1 seconds OFF) - The module is
configured and fully operational, but has not received a valid request from the host for a time longer than
the specified time out period. A communication time out has occurred.

Full ON [On] - The module is configured, fully operational, and has received communication from the host
device before the timeout period expired. This is the desired LED indication during system operation.

HALF BLINK [Long Blink] (1 second ON, 1 second OFF) - The module is not adequately configured and
requires a download from the IO Toolkit program.

Full OFF [Off] - There is no power to the module, or the status LED is being turned off intentionally by
the IO Toolkit during the module loading operation.

Off, with a quick “ON” BLINK [Short Blink] (1.9 seconds OFF, .1 seconds ON ) - The module failed
self-test at initialization. It will not attempt communication and should be replaced.

Status LED Wink Feature

The “Status” LED may be intentionally winked (10 blinks/second) by the IO Toolkit program to visually
identify the module when other modules are present.

General Information 1-3

Isolation

Every PointScan/100 Series I/O module is isolated from ground and other modules for fault-free operation.
Additional levels of isolation (e.g. 500V channel to channel isolation) are provided with some modules.
Refer to the product specifications in the IO Toolkit online help system for more information.

Local Diagnostics

Local diagnostics can be performed through any available port while the gateway is responding to
messages from the other port. Diagnostic software, such as IO Toolkit, can be used to display the status of
the I/O registers.

Hot Swap Feature

I/O modules may be unplugged from their bases, even in live systems. PointScan/100 Series I/O modules
automatically self-configure from system memory. Analog I/O logic modules will automatically upload
and self-adjust to user calibration settings (if any are present) from the module base.

Calibration

All PointScan/100 Series analog I/O logic modules are factory calibrated over all supported ranges using a
regularly maintained set of standards. Factory calibration data is stored in permanent memory in the logic
module, and cannot be altered. User recalibration may be performed, but is necessary only if inaccuracy in
your field device is observed, or if any of the 100 ohm input shunts are replaced with low tolerance
resistors.

Each analog channel has span and offset calibration settings. Span is the "range" or "gain" of the channel.
Offset is the "zero" setting. Each reported analog I/O value is the product of the factory calibration value
times the user calibration value. The user calibration value is defined as:

(user span value * raw value) + user offset

The user span is a unity value (1) by default. The user offset is zero by default.

Note: All factory and user calibrations are performed in software. There are no adjustment
potentiometers inside the logic modules.

User calibrations are performed using the IO Toolkit utility. Refer to the IO Toolkit on-line help system for
information on calibrating PointScan/100 Series analog I/O.
