2.2.7 Electrical cabinets
Electrical or industrial control panels, electrical cabinets, electrical enclosures or e-racks are boxes where electrical components are stored. These components perform different tasks for monitoring and controlling a machine or a production process.
2.2.6 Fieldbus
PLCs, HMIs and SCADA systems can communicate with each other via fieldbusses.
2.2.5 Human Machine Interface (HMI)
The HMI enables the machine operator to interact with the control loop.
2.2.4 Control loop
Sensor –> PLC –> Actuator –> Sensor is a control loop
2.2.3 Actuators
Actuators transfer the commands of the PLC into the physical world, e.g. through heating/cooling elements or motors.
2.2.2 Programmable Logic Controller (PLC)
The PLC is the heart of every modern production machine.
2.2.1 Sensors
A sensor is a device that produces an output signal for the purpose of sensing a physical phenomenon.
2.2 Process control
How to control production machines? Programmable Logic Controller, PID controls and more
2.1 Automation pyramid
One of the central frameworks in the world of OT, is the automation pyramid, international standards ISA-95 or IEC62264. This framework will be briefly explained in this section.
2. Operational Technology (OT)
OT connects own set of various technologies to create highly reliable and stable machines
1.5 Cloud
The term cloud refers to servers and the software running on them.
