As technology advances and automation becomes more prevalent in the industrial and consumer environments, there has been a need for versatile interconnectedness allowing multiple systems to work together. This is where HAL steps in and attempts to fill the need. HAL stands for Hardware Abstraction Layer and plays an integral part in allowing developers to produce code that can be performed on multiple different types of hardware. The HAL can exist on multiple layers; however, it is typically seen between the silicon and the OS so that it can be used across multiple iterations of the hardware. Whether it’s upgrading the chip in your PLC or changing the version of Android phone, HAL helps keep programs working across multiple iterations.
