8.7.3.8 Terminating Jobs
The user has the options, as described below, to naturally conclude or
terminate a job.
Terminate via R5REQ function module
The parameter word (PW3) in the job parameter list has the following
structure.
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
axxxxxxxxxxxxxxx
x = Job number (0 - 7FFFH)
a = 0 --> Start job
a = 1 --> Delete job from the queue (terminate)
It is clear from the above diagram that the job is started from Bit 15 when
logic is 0 and terminateed from Bit 15 when logic is 1, i.e., the user can
start or terminate the job with the same job parameter list. Only Bit 15
must be controlled accordingly. When a job is terminated, only the first
three parameters in the job parameter list (PW1 - PW3) are relevant. If
the user terminates a job, BÜP03E terminates the command chain and
issues a fault message.
A command chain is started via Start with the start command and is ter-
minated via Start with the termination command, as only this command is
in the command queue.
Normal conclusion via monitoring time
The Receive command enables a monitoring time to be indicated up to a
max. 10 min. If this time elapses during the Receive process, without a
character arriving from the peripheral, the Receive process is concluded
normally and is possibly stepped-on in the command chain. The time is
started with the first character for the Unrestricted Receive process and
with the start character for the Conditional Receive process. This time is
then reset when the character has been received.
Termination via termination character
The termination characters are specified in the Receive Mode command.
Depending on the setting, the Receive process is terminated with a fault
message either when single termination characters occur or when all de-
fined termination characters are positioned one behind the other. In this
case a command chain is NOT stepped-on.
