tci presents the PLC operating panel C43-XS, which is equipped with a resistive touch display with a resolution of 480*272 pixels. The 4.3-inch system supports the web visualization of various controllers. In addition to CoDeSys-based controllers, these include PLCs from Siemens, Wago, Panasonic, Schleicher, Phoenix Contact, SAIA Burgess PCD and Beckhoff. An OPC connection serves as a manufacturer-independent interface. The microbrowser, which is optimized for the processor hardware, ensures a high-performance display of the web visualization. This can include scalable vector graphics and animated HMI such as transparency, alpha blending (semi-transparency), rotation, translation, zoom and sliding windows. The connection to the controller is made via Ethernet. Power can be supplied via PoE (Power-over-Ethernet). The system without fan and hard disk is maintenance-free and has protection class IP 65.
