Program execution
If there is no item target in buffer or any item targets above the
Limit
, the program
execution waits in this instruction until there is an item in the buffer.
If the
MaxTime
argument is specified then the wait time is supervised. If the waiting
time exceeds the value of
MaxTime
and the
TimeFlag
argument is used, then the
program will continue. If
TimeFlag
is not used, then an error is raised. If
TimeFlag
is specified, this will be set to TRUE if the time is exceeded, otherwise it will be set
to FALSE.

The following recoverable errors can be generated. The errors can be handled in
an error handler. The system variable

will be set to:
Description Error code
itmsrc
undefined.
ERR_ITMSRC_UNDEF

ERR_PPA_TIMEOUT
