Autoloading Time Up Flag
The Autoloading Time Up Flag will turn ON if the time set for the Autoload
Time Up Time in the system parameters expires. This situation will occur
while waiting for data to be downloaded after executing the Autoloading Com-
mand (17D8 hex) for the Command Area using the IOWR instruction in the
ladder diagram.
If this flag turns ON, the Autoloading Error Flag (n+10, 05/n+18, 05) will also
turn ON.
The Autoloading Time Up Flag will remain ON until it is reset by turning ON
the Autoloading Error Reset Flag.
You can prevent the Autoloading Time Up Flag from turning ON by increasing
the Time Up Time or by setting the time to 00 when the time does not need to
be monitored.
