1.1. DESCRIPTION OF THE CONTROLLER AND COMPONENTS
- CONTROL BOARD
The main board is the core of the controller.
It is made of:
# a section which includes the microprocessor and the memory for the machine
control algorithm;
# an I/O section which allows interfacing with controlled devices by means of a plug-
in terminal.
# a section devised for interfacing with supervisory network and terminal which can
be installed in a remote position.
The control board represents the core of the system as it contains the
microprocessor which performs the control algorithm and the user interface
management. This board is connected to a pCO terminal and to any options.
