Programming and Communication Cables Selection Guide: Technical Criteria & Application Standards
Programming and Communication Cables selection guide: technical parameters, mounting and compliance standards, and Schneider Electric, GMT, GEMO comparison.
Programming and communication cables are ready-made data cables with connectorized ends that connect automation devices such as PLCs and operator panels (HMI) to a computer or to each other. They are used to download a prepared program from the computer to the device, for data exchange between a PLC and an operator panel, and for panel extension connections on AC drives. In this category, GMT PLC-HMI communication cables in 1.5 m, 3 m and 5 m lengths, programming cables with Mini USB and Micro USB ends, a programming cable with an Ethernet connection that is also used for panel extension on MICNO and GFD series AC drives, and GEMO RS-232 programming cables are sold by the piece. Choose the cable first according to the brand and series of the device to be connected, then according to the port type on the device (RS-232, RS-485, Mini USB, Micro USB or Ethernet) and the distance between the two devices to be connected. These products are cables with ends prepared for specific devices; they should not be confused with RS-485 or Profibus field line cables sold by the meter. The Programming and Communication Cables category on Welibaba includes 20 active models from leading manufacturers such as Schneider Electric, GMT, GEMO.
