Applications
FAB has a wide application range. For your good knowledge of its application
fields and your convenience of using it, in this chapter we will list some common
but representative control schemes, which will show you the convenience and
simplicity of auto-control by using FAB, especially the auto-control in a system
requiring time control and an intelligent living zone.
6. 1 Bell control for schools and factories
Control requirements:
Monday to Friday: From 6:00:00 to 12:00:00 AM and 14:00:00 to 17:00:00 PM,
the bell shall ring for 10 seconds every hour.
Saturday and Sunday: From 8:00:00 to 12:00:00 AM and 13:00:00 to 17:00:00
PM, the bell shall ring for 10 seconds every 2 hours.
Analyses:
In this control, there are eleven time intervals from Monday to Friday and six
time intervals from Saturday to Sunday. According to the traditional method, it
will adopt lots of time-delay relays and its circuit will be very complex. FAB,
by contrast, only needs a line section for its external circuit, or we say that we
are able to implement the bell control only by connecting a FAB output port to
the bell. The program diagram is shown as follows:
