long PamuxAnaWatchdogTime
long
hHandle
Sets the value of the watchdog timer in
units of hundredths of a second. Set-
ting Time100 to 0 disables the watch-
dog. Setting the time to 0 can also be
used to reset the watchdog error flag if
it has tripped. This and any other ana-
log function can be used to “tickle” the
watchdog to prevent it from tripping.

Parameter Description
long PamuxAnaStatusGetAsError
long
hHandle
Gets an analog board’s status and
returns an equivalent error. Analog read
functions also return the same result
after performing their read. An analog
configure function can be used to clear
the “power-up” error. The “old data”
error is cleared by the B6 processor as
it updates inputs. This function could be
used to wait for fresh input data.
