What Is Machine Automation?

The term machine automation refers to techniques and equipment used to automate the operation of a piece of machinery, production line, or manufacturing process. Examples include CNC machine tools, automated production lines, and robotic controls. Benefits include lower unit and labor costs, increased production volumes, greater flexibility and repeatability, and improved machine utilization. A common example is CNC lathes that automatically machine complex parts to precise tolerances.  

Machine Automation Solutions (Siemens)

There are many levels of automation. These include:

  • Simple programmable logic controller (PLC) for machine control

  • Complex integrated systems managed by multiple controllers

  • Supervisory control and data acquisition (SCADA) systems for managing entire production processes

Common features of machine automation include hardware, such as PLCs, servo controllers, and machine inputs and outputs controlled by a program written in a PLC programming language. Advanced Controls and Distribution is a Siemens distributor supplying the full range of Siemens automation systems.  

Machine Automation Hardware

Automation hardware includes PLCs, human-machine interfaces (HMI), motion controllers, and data communication systems.


The PLC represents the brains of any automation solution. It is programmed using special PLC software to perform certain actions. The Siemens PLC family includes different models including:

  • Simple LOGO controllers

  • Basic S7-1200 controllers

  • Advanced S7-300, 400, and 1500 controllers

  • PC-based industrial computers

Human-Machine Interface

The HMI allows operators to control PLC systems. They have touch-sensitive display screens that you can configure flexibly to suit the process. Screen programmable options include soft switches, process flow charts, and graphical data. Other options include SIMATIC flat panel displays and SENTRON instrumentation displays.

Power Supplies

Most Siemens PLCs don't incorporate a power supply and use an external power supply to supply regulated 24-volt DC power to the PLC. Depending on the model, PLC power supply outputs include 5-, 10-, 15- and 20-amps DC. Siemens power supplies incorporate short circuit protection to protect PLC equipment from damage and power surges.

Motion Controllers

Siemens motion controllers incorporate accurate speed and positioning control suitable for precise motor positioning and speed control and robotic controls. SIMOTION controllers are compatible with analog and digital inputs and outputs.

CNC Control

Siemens' SINUMERIK and SINAMICS CNC controllers are specifically engineered for computer numerical control applications required for precision machining centers and lathes. Components include programmable controllers, expansion units, keyboards, operator panels, and remote handheld controllers.
