Fig. 5-5 R5REQ — PLC response

This word indicates on which R500 and via which channel this job is to be
processed.
The CXN is entered in the HIGH byte of this word. The CXN is specified
by the R5INIT function module (see Page 4-2).
The channel number indicates via which module interface the job is to be
processed.

Up to 16 jobs can be started in parallel with the computer interfaces of the
CL400/CL500. These jobs can be differentiated by the job-number infor-
mation. Another job with the same job number cannot be started until the
previous one has ended. An attempt to run two jobs with the same job
number will be rejected by the R5REQ with a fault message.
However, several centralised jobs which have different job numbers in
one PLC cycle can be started.
The R500 can process up to 16 jobs in parallel. The R500 has 16 job
channels for this purpose. The job numbers 0 to 15 are assigned directly
to the job channels. Jobs with larger job numbers search for the next free
job channel on the R500. Therefore, the job numbers from 0 to 15 should
not be mixed with larger job numbers, otherwise jobs may be rejected de-
spite free job channels.
The job numbers can accept a value from 0 to 7FFFH.
Jobs which have been transferred to the computer interface and are wai-
ting to be processed are deleted from the job queue by the 16th bit of the
job number.
The job numbers 12 to 15 are reserved for high-priority jobs. The infor-
mation on this parameter ensures that this job is given a high priority and
is processed accordingly.
