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 counter registers the request interface of the SFB 47
may be used. So that a new job may be executed, the previous job
must have be finished with JOB_DONE = TRUE.
