1.6.1 Module Power-up

At power-up, the module performs a check of its internal circuits, memory, and basic

User’s Manual Pub. 0300257-01 Rev. A

1-4 Point IO™ 2/4 Channel Analog HART Module

functions. If no faults ar e found during power-up diagnostics, the module status LED is
turned on.

After power-up checks are complete, the module waits for valid channel configuratio n
data. If an invalid configuration is detected, the module will generate a PLC fault. Once
a channel is properly configured and enabled, it continuously converts the input data to a
value within the range selected for that channel.

1.6.2 Module Operation

The 1734sc-IE2CH and IE4CH modules are single ended 4-20mA current sensing input
modules with HART master capability. Analog current is measured by sensing voltage
drop across an internal resistor. The nominal input resistance of individual channels is
250ohms. In the event of an over-current fault the module will protect the input circuitry
by increasing the input resistance to limit input current. Analog to digital conversion is
performed by a multiplexed Sigma-Delta ADC shared by all channels. A range of notch
filters as well as an averaging filter can be applied to analog inputs. All channels share a
common ground. Field power is provided on the terminal block to simplify wiring. The
1734sc-IE2CH and IE4CH have HART Primary Master capability. A dedicated HART
modem is used for each channel for maximum throughput. When HART functionality is
enabled on a channel the module will discover and establish communication with HART
revision 5 and greater devices. Once communication has been established the module
will automatically gather HART PV, SV, TV, FV data and monitor device status. The
modules pro vide a communication br i dge to HART devices for Asset Management
Software and Ladder Programs via CIP messaging.

Chapter 3
Configuring the 1734sc-IExCH
Using RSLogix 5000

This chapter covers the following subjects:

• Introduction

• About Communications

• Use Generic Profile

• Use AOP (Add On Profile)

• Module configuration

• Reading input data

• Module update time

Section 3.1
Introduction

Section 3.2
About
Communications

The 1734sc-IE2CH and IE4CH allow, in addition to reading the 4 to 20 mA analog
signal, the ability to read and write HART data to and from HART compatible devices.
This chapter will describe how to configure the IExCH module using RSLogix 5000
programming software.

The module produces and consumes data as follows:

IE2CH Produce/Consume Data

Input Assembly Options I/O Connection Type Consumes Produces

Analog + HART 0, 1 Change-of-State 0 Bytes 60 Bytes

IE4CH Produce/Consume Data

Input Assembly Options I/O Connection Type Consumes Pr oduces

Analog + HART 0, 1, 2, 3 Change-of-State 0 Bytes 112 Bytes

The IExCH module is not compatible with the 1734-ADN, ADN(X), and

installed behind a Control Net adapter (1734-ACNR). Only update
firmware when the module is installed behind an Ethernet adapter
(1734-AENT or 1734-AENTR).

limit of 600 bytes. Therefore, the maximum number of 1734sc-IE4CH
modules that can be installed behind a ControlNet adapter is four and
the maximum number of 1734sc-IE2CH modules is eight.

Section 3.3
Use Generic
Profile

The generic point IO module profile can be used to represent the IExCH module within
RSLogix 5000. The generic profile should be used for RSLogix 5000 versions 14 and
older. Before the generic profile can be added to the IO configuration, the proper
communication module needs to be added to the IO configuration first. Follow the
procedure below to add a communication module to RSLogix 5000.

1.) Add the new local communication module to your project.

2.) Configure the local module, including:
a. Naming the module
b. Choosing a Communication Format
c. Setting the Revision level
d. Setting the module location as necessary such as the slot number for a

1756-CNB module

e. Choosing an Electronic Keying method

3.) Add the new remote module to your project, such as a 1734 Control Net adapter

or Ethernet Adapter (i.e. 1734-ACNR or 1734-AENT, respectively).

4.) Configure the remote module similarly to the local module

5.) Download the configuration to the controller

Note: If you are using Control Net, you must schedule the network using
“RSNetworks for Control Net” after adding the local and remote
communication modules.

Note: When you create a new RSLogix 5000 project with the CompactLogix
1769-L32C or L35CR controller, The Controller Organizer creates a Control
Net port in the local chassis. In this case, you don’t need to add a separate
local communication module.

Note: When you create a new RSLogix 5000 project with the CompactLogix
1769-L23E, 1769-L32E or L35E controller, The Controller Organizer creates
a Ethernet port in the local chassis. In this case, you don’t need to add a
separate local communication module.

3.3.1 Add a Local Ethernet Bridge Module

After you have started RSLogix 5000 software and created a controller project, you can
add Ethernet communication modules. A local Ethernet communication module is a
module that resides in the same chassis as the controller.

1.) Select a New Module for the I/O Configuration.

3.3.2 Add a Remote Ethernet Point IO Adapter

After you have added the local Ethernet communication module, you must add remote
Ethernet communication modules. A remote Ethernet module is a module that resides in a
separate chassis fr om the controller.

If you plan to use the 1734 Control Net adapter, you will need t o install
