8.5 Centralized control and monitoring of  
several factory doors
Often, a company’s premises can be entered at several lo-
cations. 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 FL1D-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.
