Figure 1-6. A Basic System
An assembly of baseplate and modules such as this one is called a “Rack.”
What else would be needed to make this basic system functional?
To make this basic system functional, you would need:
Mounting.
Safe, secure mounting for the PLC in a protective enclosure.
Wiring.
This includes properly installed incoming power to the power supply, as well as
wiring from the I/O modules to field devices such as switches, sensors, solenoids, relays, etc.
Program
. An application program for the PLC to run. This is developed with GE PLC
programming software.
What if the application requires more than five modules?
You could use a 10-slot baseplate, shown in the next picture:
