Program Plan Intro
SCADA system:
- The Supervisory Control and Data Acquisition (SCADA) system refers to a system of software and hardware elements.
- Generally, a SCADA system is a system which coordinates but does not control processes in real time.
- One of the advantages of a SCADA system is that the stored data can be retrieved for later analysis without any error or additional work.
- SCADA systems are normally used by industrial organizations and public as well as private sector companies to control efficiency, distribute data, maintain efficiency, and communicate issues with the system to help mitigate downtime.

Describe various CONTROLLED ACCESS methods along with diagrams
A home security system has a master switch that is used to enable an alarm, lights, video cameras, and a call to local
police in the event one or more of six sets of sensors detects an intrusion.
In addition there are separate switches to enable and disable the alarm, lights,
and the call to local police. The inputs, outputs, and operation of the enabling logic are specified as follows:
Inputs:
S: signals from six sensor sets (8 =
M: master switch (0 = security system enabled, 1 = security system disabled)
A: alarm switch (0 = alarm disabled, 1 = alarm enabled)
L: light switch (0 = lights disabled, 1 = lights enabled)
P: police switch (0 = police call disabled, 1 = police call enabled)
intrusion detected from the sensors, 1 = no intrusion detected)
Outputs:
A: alarm (e = alarm on, 1 = alarm off)
L: lights (0 - lights on, 1 - lights off)
V: video cameras (0 = video cameras off, 1 = video cameras on)
C: call to police (8 = call off, 1 = call on)
Operation:
If one or more of the sets of…
It is necessary to describe how finite-state machine control is implemented.
