Every industry and every facility is a unique system and environment. This is true even with similar types of industrial processing lines, with differences in configuration, equipment and processes all contributing to making the anything but identical.
To accommodate the differences, there are a variety of options in industrial automation controls. Having an idea of the pros and cons of each type of automation control system and the possible concerns of installing it in your production facility will be essential to make an informed and educated decision.
Most businesses will rely on their industrial automation company to make suggestions and recommendations. In the initial planning phase of the project, ask for the specific reasons why one type of control system is being recommended over the others. This is a great question to pose when interviewing different providers to find out if there are common recommendations from companies or if one company is recommending a system that is not advised by the others.
PLC
Programmable logic controllers are still the gold standard for most installations. This is particularly the case when the working conditions are less than ideal for the more sensitive electronic systems.
These are systems with a memory as well as a microchip, which means they are more than just automatic off and on controllers. They can also be used together in relays, avoiding a lot of cost in separate standalone controllers.
PAC
The PAC or programmable automation controllers are a more advanced version of the PLC, offering additional functionality. They incorporate motion control, process control as well as the ability to complete specific tasks such as testing, scanning or other requirements.
PC Enabled
For all types of soft motion, which includes greater use of software over actual hardware, a PC-based controller may offer the type of advanced control and customization that is required.
These systems run on rugged PCS that are specifically protected to boost reliability and durability even across challenging operating conditions. Often considered the most practical when multiple partitions are required to operate the system while still maintaining high levels of security and breach prevention.
