Modbus as a communication protocol is often used by PLC controllers to transmit process data. It is ideal for communication with an HMI as a display for outputs and inputs. The EA HMIxxx series offers brilliant displays for Modbus in various sizes. As Modbus/RTU, the HMI communicates via an RS485 interface and as Modbus/TCP via Ethernet (LAN). Data is exchanged bidirectionally via Modbus registers; this means that not only output is possible on the HMI/display but also input via touch panel.
Only 24V are required for operation, the rest is already integrated in the HMI. Installation is simple and flexible on the wall or in a housing or front panel.
As an HMI, the Modbus display supports communication with over 20 different PLC models, including Siemens S7-200, S7-1200/1500, S7-300/400, Allen Bradley, Mitsubishi FX, Beckhoff and many more.
