If you are looking to purchase a PLC system, there are three key components that you should look for. If your current system does not contain these features, you need to replace it with one that does as soon as possible. The three most important features you should look for in your new PLC system are the open communications protocol, the ability to integrate easily with other methods, and the ability to have remote access. Without these three essential requirements, your PLC system will be far less effective and will be more expensive to operate than it needs to be.
We are all data companies that need the information for continued improvement. The industrial internet of things (IIoT) is essential, and the ability to take advantage of this starts with the hardware you specify for your PLC control. PLCs are now considered edge devices. This means that information should be able to be sent and received to the PLC controller when it is required.
HMIs offer different people information and control in many ways for the automated system. Operators, supervisors, mechanics, electricians, engineers, and programmers all have different needs. The machine HMI(s) must provide or make the information easy for all the people who use the system.
