FLEX I/O Isolated Input HART Analog Module 23
Publication 1794-IN115C-EN-P - April 2009
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.
