Utilities are available for Unitronics HMI/PLC products and TURCK I/O products. Unitronics VisiLogic free software provides a user-friendly environment for hardware configuration, modular ladder application development, and HMI design, including a rich color library of industrial images. TURCK has launched the latest version of its popular I/Oassistant software, V3.0. It is now available for download completely free of charge at www.turck-usa.com, I/Oassistant is used as a configuration tool when designing TURCK’s BL20 in the panel and BL67 on the machine nodes. It can verify I/O arrangements and make suggestions based on power consumption and part compatibility—all while allowing the user to create a documentation set that includes photos of the station, a list of settable parameters, dimensions of the station for mounting considerations and a complete bill of materials. It will even generate the fieldbus I/O map for reference. I/Oassistant is also used when commissioning and troubleshooting hardware. Users can automatically import the hardware node or add each module separately. All TURCK BL gateways come equipped with a maintenance port that connects to a computer via RS232, or they may be connected using Ethernet (when equipped). When connected, the system can read inputs, write outputs, read diagnostics, and read/change parameters.
