What does HMI stand for?
HMI is an abbreviation of Human Machine Interface which is the link between the user and the PLC. HMI typically exists in the shape of a touch sensitive screen or computer, providing the user with the ability to control a smaller installation. The HMI and SCADA expressions are often used interchangeably, though they are not the same. A SCADA-system have a Human Machine Interface, but this interface is not the SCADA-system. The biggest difference between the two is that a SCADA-system can control the entire facility centrally and collect data. With the HMI you can only control a small part of the facility, such as a single installation, and it is not possible to collect data. In effect this will often mean that the SCADA-system will be found in places such as a control room, providing an overview of multiple things, whereas the HMI will be near the single installation it is for. At Logimatic we create HMI and SCADA-systems as tailored solutions and our work is based on the ISA-101 HMI standard.
What is HMI used for?
The expression can be used to describe almost any screen, though it is most often used in an industrial context. The function varies, but at its core it is used to display some sort of data. Perhaps the interface is used for diagnosing problems, or tracking a workflow, and is also used for monitoring critical values such as temperatures. There are many possibilities but the most important factor is that the information displayed is tailored to your demands.
Who uses HMI?
The use of this type of interface is widespread, and given that it can be tailored for different needs, it is used in a variety of different industries. At Logimatic we are specifically experienced in delivering to the maritime, sewage, waste water and supply industries.
