8.5 Centralized control and monitoring of 
several factory doors
Often, a company’s premises can be entered at several
locations. Not all of the gates can always be monitored
locally by personnel. They must therefore be able to be
monitored and operated by the porter who sits in a central
gatehouse.
It must also be possible for a member of staff to open and
close the gate locally.
For each gate we are going to use one FL1E-H12RCC and
one communication module. The modules and the master
are interconnected by means of a bus system.
This chapter describes a gate control system. The structures
of the other gate control systems are identical.
