8-2 Troubleshooting the Module
Locating Error Code
Information You configure the 1746-BTM module to report error codes by setting
bits 10–8 to 100 in word 192 of the output image buffer table Refer
to Using the Output Image Table on page 5-8. The module reports
error codes in input image table words 172-175.If using the sample
program, error codes are reported in N10:212-215. Location of the 2–
digit code in the error word determines its source:
module status
indicator is ON self–check is completed satisfactorily
module is OK normal power–up
module waiting for channels to be
enabled
module status
indicator is flashing communication occurring between
SLC processor and the BTM module normal operation
Indication Probable Cause Recommended Action:
Display of error code in
N10:212-215 if using example
program
xx yy
Autotune error code Configuration
error code
Autotune error codes only reset
when an autotune is invoked. A configuration error code is
only reset when the reset error
code bit is transitioned.
EXAMPLE
If 002 is displayed, the error code is from the
configuration block.
If 6700 is displayed, the error code is from the
autotune.
