FLEX I/O Isolated Output HART Analog Module
19
Publication 1794-IN120D-EN-P - September 2015
Status Indicator
The OK status indicator is bicolor, red, and green. The indicator flashes green for these
reasons:
•
The module configuration word is zero (for example, powerup reset condition).
•
The 24V DC user power is off.
•
The module is in Configuration mode.
The indicator displays red to indicate the module did not pass the initial hardware test.
Recycle power in response to this display.
After powerup, if the status indicator is not flashing green or solid green, recycle module
power to verify a proper reset of the bus interface.
