Error Codes The SLC processor reports error codes in word 6 of the SLC processor
status file. Below are the format of the status word and applicable
error codes.
For a complete description of the error codes, refer to the user manual
provided with your programming device.
Retry Counters Electrically noisy environments can cause RIO communication
problems. You can use the retry counters to determine if your scanner
is having problems communicating with configured devices. To access
retry counter information, you must view status file words M1:e.16
through M1:e.31 (and M1:e.32 through M1:e.47 if complementary I/O
is used). These counters display the number of communication retries
the scanner has made. See the section on retry counters in Chapter 4,
Configuration and Programming for more detailed information.
Block Transfers If you are having problems with Block Transfers, see Chapter 5, RIO
Block Transfer, for information on error codes.
