1.5.1 LED Indicators
The 1734 analog HART module uses several LEDs to show operational status. The
status LEDs are defined below:
Table 1-1 (LED Status Indicators)
Indicator State Description
Module Status
Off No power applied to device
Green Device operating normally
Flashing Green Device needs commissioning due to configuration
missing, incomplete, or incorrect

- Device not powered - check module status indicator
Flashing Green Device is on-line but has no connections in the
established state.
Green Device on-line and has connections in the established
state.
Flashing Red One or more I/O connections in timed-out state
Red Critical link failure - failed communication device.
Device detected error that prevents it communicating
on the network.
Flashing

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
