1.5.1 LED Indicators

The 1734 analog HART module uses several LEDs to show operational status. The LEDs for the module consist of four Red/Green LEDs representing Module Status, Network Status, and two Output Connection Status LEDs. The status LEDs are defined below:
Table 1-1 (LED Status Indicators)
User’s Manual Pub. 0300272-01 Rev. A.0
Chapter 1: Module Overview 1-5
NOTE
If the module loses its IO connection during operation (physically disconnected from controller or Inhibited), the module functions as if the Inhibit checkbox was selected during setup. During the interval in which there is no IO connection, the outputs are disabled. Once the connection is re-established and a valid configuration is received, the outputs will run normally.

Section 1.6 System Overview

The module communicates to the controller via an Ethernet adapter. The module receives 5 and 24 VDC power through the PointBus backplane bus interface.

1.6.1 Module Power-up

At power-up, the module performs a check of its internal circuits, memory, and basic functions. If no faults are found during power-up diagnostics, the module status LED is turned on. By default, the module powers up with both channels disabled and powered down until valid configuration information is received.
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 output data to a value within the range selected for that channel.

1.6.2 Module Operation

The 1734sc-OE2CIH has two, single-ended, 4-20 mA and 0-20 mA isolated current output modules. HART capability is available only on the 4-20 mA range. The module is fault protected to ±24 VDC. The module also contains a 16-bit DAC. The 1734sc­OE2CIH has 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 discovers and establishes communication with HART revision 5 and greater devices. Once communication has been established, the module automatically gathers HART PV, SV, TV, and FV data, and monitors device status. The modules provide a communication bridge via Common Industrial Protocol (CIP) messaging to HART devices for Asset Management Software and Ladder Programs.

Section 2.5 Field Wiring Connections

Consider the following when wiring your system:
General
Power and input wiring must be in accordance with Class 1, Division 2
wiring methods, Article 501-4(b) of the National Electric Code, NFPA 70, and in accordance with the authority having jurisdiction.
Use Belden™ 8761 or equivalent, shielded wire. To ensure optimum accuracy, limit overall cable impedance by keeping a
cable as short as possible. Locate the module as close to input devices as the application permits.
Digital and analog power must be supplied by an Isolated Secondary
Limited Energy Low Voltage source.
Outputs
The module provides loop power for analog outputs.
Grounding
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:
- For grounded thermocouples or millivolt sensors, this is at the
sensor end.
- For 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 120 V 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.
