A human machine interface (HMI) connected to a separate programmable logic controller (PLC) is the standard system for machine automation. However, combining PLC processing and HMI monitoring and control into a single hardware platform is becoming a more available and popular option due to improvements and advancements in both hardware and software. This article compares the combined HMI+PLC unit with the separate HMI & PLC system and highlights where each excels.
