certain errors in the ERROR SPECIFIC field. 31" errors are decoded
at the bottom of the Error Log. Note that the error log for AutoMax
tasks is maintained through a power cycle; the error log for UDC

UDC error log is cleared when power is removed from the rack. For
more information about clearing the error log, see 19.0.
Like AutoMax tasks, UDC tasks can also access the error log by
using the BASIC function TST_ERRLOG@ and the statement
CLR_ERRLOG@.
