An HMI (human-machine interface) is the screen where operators see machine status, alarms and trends and enter setpoints and commands. In industry it is usually a touch panel mounted in a cabinet door and connected to the PLC over Ethernet or a serial port. SCN supplies HMIs and operator panels from Weintek and Yaskawa, configured with EasyBuilder Pro or Movicon.<\/p>\n
The HMI panels<\/a> range covers Weintek cMT X panels from 4.3 to 15.6 inches with IP66 fronts, wide-angle or Full HD IPS displays and CAN bus, Yaskawa TP-SM panels in 4.3, 7 and 10.1 inches, and TP C panels from 6.5 to 12 inches with Movicon CE. The screenless cMT-SVR servers and the cMT-FHDX-820 with HDMI output run the HMI project on a DIN rail and show it on a tablet, PC or any monitor. Under Distributed I\/O<\/a> you find Weintek iR couplers for Modbus TCP, CANopen and EtherCAT. The controllers are under PLC systems<\/a>, and all control products under Control Systems<\/a>.<\/p>\n How to choose:<\/strong> start with the screen size the operator needs, check which protocol your PLC uses, then the front protection, operating temperature and whether you want remote access or a screenless HMI.<\/p>\n An HMI, short for human-machine interface, is the display and software operators use to monitor and control a machine or process. It shows live values, alarms and trends from the PLC and sends commands back, replacing push buttons and indicator lamps. Industrial HMIs such as the Weintek cMT series run on 24 V DC, have IP66 fronts and log alarms and data.<\/p><\/details>\nFrequently asked questions<\/h3>\n
