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)
