between modules
Apparatus control
BLKCON is used for blocking of functions in a bay and in an apparatus
control program. BLKCONL (x=1) contains one blocking function and
BLKCONK (x=1, 2 and 3) contains three blocking functions. The block-
ing function can be controlled with both steady and pulse signals. The
functionality can be represented by logic as in the Fig. 10 below.

Fig. 11 is used as starting-point when explaining the signal flow between
the different function block in the apparatus-control function. The control
program in Fig. 11 handles one bay, which includes two apparatuses. The
detailed connections between the modules can be seen in the type solu-
tions in the "Configurations" on page 25.
