Section 1.6
System
Overview
The module communicates to the controller via a 1734 Control Net, Device Net or
Ethernet adapter. The module receives 5 and 24V dc power through the bus interface.
Note: No external power supply is required for 2-wire input transmitters.
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 are found during power-up diagnostics, the module status LED is turned on.
After power-up checks are complete, the module waits for valid channel configuration 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 provide a communication bridge to HART devices for Asset Management Software and Ladder Programs via CIP messaging.
See the block diagram below.

2.3.2 Prevent Electrostatic Discharge
Electrostatic discharge can damage integrated circuits or
!semiconductors if you touch analog I/O module bus connector pins or
the terminal block on the input module. Follow these guidelines when Attention you handle the module:
•Touch a grounded object to discharge static potential.
•Wear an approved wrist-strap grounding device.
•Do not touch the bus connector or connector pins.
•Do not touch circuit components inside the module.
•If available, use a static-safe work station.
•When it is not in use, keep the module in its static-shield bag.
2.3.3Remove Power
Remove power before removing or inserting this module. When you
! |
remove or insert a module with power applied, an electrical arc may |
|
|
|
occur. An electrical arc can cause personal injury or property damage |

Attention
•This product is intended to be mounted to a well-grounded mounting surface such as a metal panel. Additional grounding connections from the module’s mounting tabs or DIN rail (if used) are not required unless the mounting surface cannot be grounded.
•Under normal conditions, the drain wire (shield) should be connected to the metal mounting panel (earth ground). Keep shield connection to earth ground as short as possible.
•Ground the shield drain wire at one end only. The typical location is as follows:
oFor grounded thermocouples or millivolt sensors, this is at the sensor end.
oFor insulated/ungrounded thermocouples, this is at the module end. Contact your sensor manufacturer for additional details.
•Refer to Industrial Automation Wiring and Grounding Guidelines, AllenBradley publication 1770-4.1, for additional information.
Noise Prevention
•Route field wiring away from any other wiring and as far as possible from sources of electrical noise, such as motors, transformers, contactors, and ac devices. As a general rule, allow at least 15.2 cm (6 in.) of separation for every 120V of power.
•Routing field wiring in a grounded conduit can reduce electrical noise.
•If field wiring must cross ac or power cables, ensure that they cross at right angles.
•If noise persists for a device, try grounding the opposite end of the cable shield or ground both ends of the shield.

!PDN device net adapters and the 1734-APB profibus adapter.
Attention
!
Attention
It is not recommended to update module firmware if the module is 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).
User’s Manual Pub. 0300257-01 Rev. A

Point IO™ 2/4 Channel Analog HART Module |
The ControlNet adapter (1734-ACNR) has a maximum data transmit
! |
limit of 600 bytes. Therefore, the maximum number of 1734sc-IE4CH |
|
modules that can be installed behind a ControlNet adapter is four and
Attention 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 from the controller.
If you plan to use the 1734 Control Net adapter, you will need to install ! the 1734sc-IExCH EDS file before scheduling the network. The latest
EDS files can be found at (www.spectrumcontrols.com).
