ErrorMode

Optional. Specified as a decimal representation of a hexadecimal bitmask. Values must be specified in decimal format. The following table shows the possible values.

Value Name Description

0 (0xnnnn0000)

DAERH_ABORT

Default. The abort-on-error mode stops the command file from processing further.

32768 (0xnnnn8000)

DAERH_IGNORE

The ignore-on-error mode continues by processing the next command when an error occurs.

32769-33023 (0x000080xx where xx!=00 is the number of retries)

DAERH_RETRY_WITHIGNORE

The retry-on-error with ignore mode retries the offending command up to 255 times. If the number of retries exceeds the retry count, this mode continues processing the next command.

1-255(0x00xx where xx!=0 is the number of retries from 1-255)

DAERH_RETRY_WITHABORT

The retry-on-error with abort mode retries the offending command up to 255 times. If the number of retries exceeds the retry count, the command file processing halts.

65536 – 4294901760(0xFFFFnnnn where FFFF is the delay mask in seconds)

DAERH_DELAYMASK

The delay error mode value is added to either the DAERH_RETRY_WITHIGNORE or the DAERH_RETRY_WITHABORT value to cause a delay between retries. This value is in seconds and has a range between 1 and 65535.

Bb521633.note(en-US,WinEmbedded.51).gifNote:
Parsing errors, especially the passing of not valid command parameters, generates an error in DAERH_ABORT error mode. With logging enabled, an appropriate error message is output to the log file.
