In today’s technologically-advanced product markets, there are many devices that allow us to streamline and customize machinery in order to maximize efficiencies and minimize waste. Few products can have as profound an impact on your operations as the many Human Machine Interface (HMI) products that are available today.
While they are available in many formats and sizes, HMIs are all compact, easy to mount, simple to connect and infinitely programmable. Even so, their full capabilities are often underutilized. Machines are controlled by touchscreens or keypads, enabling operators to control processes from their respective HMIs, but how often do we see these HMIs controlling multiple machines and processes at once? With their enormous processing capabilities, it doesn’t make sense to limit an HMI to a single machine, and a thoughtful programmer can use a single HMI and expanded PLC I/O to control many machines to eliminate the need for multiple HMIs and their associated PLC components. Resultant hardware savings can then be used to improve or build additional machines needed to keep up with demand, or upgrade existing equipment to increase efficiencies.
Additionally, HMIs can be used as replacements for banks of switches and pushbuttons, which can quickly amount to significant savings. Modern HMIs provide a more capable, effective and flexible control solutions to your customers or plant personnel.
