General Information 1

Overview

The PointScan/300 Series DIN rail mounted I/O that provides direct field wiring connections to a wide
variety of industry devices. The PointScan/300 Series I/O and Windows software form a high
performance, flexible I/O system.

A typical PointScan/300 Series station consists of a DC power supply, a communication gateway, and I/O
modules. The gateway connects to the I/O modules through a daisy-chained "PT-Bus" cable.
(See Section 3.)

Overview 1-1

I/O Module Components

A PointScan/300 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/301, /302, and /304) 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.

Status LED Indication

The “Status” LED on each module may be observed in one of five states:

ON - The module is configured properly and communicating with the gateway.

OFF - There is no power to the module, or the status LED is being turned off intentionally by the I/O Tool
Kit during the module linking operation

LONG BLINK (
has lost communication with the gateway for more than 10 seconds, or the module has not received
configuration data from the gateway. Upon initial system startup (no configuration in the gateway) this

10 blinks/ sec.) -

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.

Isolation

Every PointScan/300 Series I/O module is isolated from ground (1200Vrms @ 1 minute) and additional
isolation is available on select modules (e.g. PointScan/323, 500V channel to channel isolation) for
fault-free operation. Additional levels of isolation are provided with some modules. Refer to the product
specifications in the Remote IO Toolkit online help system for more information.

Long blinking indicates one of two conditions. Either the module

Short blinking indicates a failure of the module self test upon

A status LED may be winked by the I/O Tool Kit utility to bring attention to the

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/300 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.

PointScan/300 User’s Manual

9-26-01

Overview 1-3

Gateway Memory

All PointScan/442 gateways have nonvolatile (battery-free) memory for storing configuration data from the
I/O Toolkit utility.

Programmable gateways have battery-backed memory for storage of program variables and logged data.
The battery is a rechargeable lithium cell that is kept fresh by the power circuitry in the gateway. The
memory retention period for an unpowered gateway is at least one year at room temperature. The retention
time will be shorter at higher temperatures. The life expectancy of the lithium battery is approximately 10
years.

Calibration

All PointScan/300 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/300 Series analog I/O.

Getting Started With PointScan/300 Series Hardware

Following these steps will make installation and start-up easier.

nMount the Hardware

If you purchased individual PointScan/300 Series components, refer to Section 2 for information on

installation instructions.

oInstall PT-BUS Wiring Between Modules

Make PT-BUS wiring connections between the PointScan/300 Series modules.
Refer to Section 3 for PT-BUS wiring guidelines.

p Connect Power and I/O Wiring to the Modules

Connect AC power to the PointScan/300 Series power supply. Make DC power connections from the
power supply to the gateway and I/O modules (as needed.) Make field wiring connections to the
PointScan/300 Series I/O modules and any peripheral equipment. Refer to the individual module sections
in this manual for connection details.

qInstall Communication Cabling

If you did not purchase a factory communication cable (CA-22), install a RS232 cable between your
computer and serial port on the PointScan/300 Series gateway.

Fabricate and install RS232, RS422 and RS485 cables as needed. If you are using Ethernet gateways,
(PointScan/442) install the correct cabling and peripherals. Refer to the documentation for your Ethernet
communication devices for details.

r Apply Power

Power up the PointScan/300 Series I/O and related peripherals. Observe the status LED on each module.
The normal conditions are as follows:

Module Type

Gateway (PointScan/442) Power and Status LEDs On
I/O modules PointScan/300 Series
in user enclosure
PointScan/443 Power LED on

s Configure Using IO Toolkit

Refer the steps outlined in the online help for each PointScan/300 Series module.

t Test the System

Use the Test I/O window in the IO Toolkit program to verify proper I/O operation in all PointScan/300
Series module.

PointScan/300 Series Panel Assembly

PointScan/300 Series I/O snaps onto DIN rail strips fastened to the subpanel. Figure 2-4 shows a sample
panel with DIN rail strips and wire duct attached. Recommended DIN rail spacing is 8 inches. This spacing
allows room for wire duct to be installed without obstructing field wiring installation.

The PointScan/300 Series modules are typically installed against one another, but space may be left
between modules to accommodate other DIN rail mounted components such as terminal blocks and fuse
holders. End clamps are recommended to restrict side-to-side movement. Figures 2-5 through 2-7 show the
physical dimensions of the PointScan/300 Series components.

PointScan/300 Series modules may be installed in any orientation and order on your panel. The modules
are electrically interconnected using PT-Bus wiring, beginning with the gateway. Refer to Section 3 for
more information on PT-Bus wiring.
