Product details

The Siemens 6AG1128-3MB06-4AX1 is a graphical HMI panel equipped with PROFINET, supporting DCP and MRP for industrial network integration. It operates in a temperature range of -20 to 60 °C and has an IP20 protection rating on the rear.

Network integration

DCP (Discovery and Configuration Protocol) is supported, allowing automatic PROFINET device identification and address assignment. MRP (Media Redundancy Protocol) enables network redundancy for ring topologies. DHCP and LLDP are also available for flexible network configuration.

The HMI includes physical buttons, sliders, and a buzzer for operator feedback and alarm annunciation. It supports bar graphs, I/O fields, alarm views, and user views for visualization. JavaScript scripting enables custom logic.
