Error Codes

There are several methods used by the DLI and ADCCP NRM software to report errors

(Ta bl e B –1 lists the ADCCP NRM errors):

1. The error code can be returned directly by the DLI function call. Typical errors

are those described in the Freeway Data Link Interface Reference Guide.

2. The ADCCP NRM errors shown in Ta bl e B –1 can be returned in the dlRead

pOptArgs.iICPStatus

field of the response. The DLI sets the dlRead

pOptArgs.usProtCommand

field to the same value as the dlWrite request that caused

the error. The

DLI constants are defined in the file dlicperr.h.

3. The ADCCP NRM error can be reported in an error report response to a dlRead

request. The returned dlRead pOptArgs.usProtCommand field is set to

DLI_PROT_RESP_ERROR, and the dlRead pOptArgs.iICPStatus field is set to the actual

error code.

4. Under certain communication line conditions that cause queued transmission

buffers to be discarded, the ADCCP NRM error can be reported in a data

acknowledgment response to a

dlRead request. In this case, the returned dlRead

pOptArgs.usProtCommand

field is DLI_PROT_RESP_NORMAL_ACK, and the dlRead

pOptArgs.iICPStatus

field is set to the actual error code.
