Output value for read request.
Per channel you may call the SFB in each case with the same instance
DB, since the data necessary for the internal operational are stored here.
Writing accesses to outputs of the instance DB is not permissible.
To read/write the registers of the frequency meter the request interface of the SFB 48
may be used.
So that a new job may be executed, the previous job must have be finished with
JOB_DONE
= TRUE.
The deployment of the request interface takes place at the following sequence:
