Default Configuration
If a write block of five words with all zeroes is sent to the module,
default selections will be:
•
1 to 5V dc or 4 to 20mA (dependent on configuration jumper
setting)
•
BCD data format
•
no real time sampling (RTS)
•
no filtering
•
no scaling
•
single-ended inputs
The front panel of the analog input module contains a green RUN
indicator and a red FAULT indicator. At power-up, the module
momentarily turns on the red indicator as a lamp test, then checks
for:
•
correct RAM operation
•
firmware errors
If there is no fault, the red indicator turns off.

Green RUN indicator
Red FAULT indicator
The green indicator comes on when the module is powered. It will
flash until the module is programmed. If a fault is found initially or
occurs later, the red fault indicator lights. The module also reports
status and specific faults (if they occur) in every transfer of data
(BTR) to the PC processor. Monitor the green and red indicators and
status bits in word 1 of the BTR file when troubleshooting your
module.
