Overview
The 6AG1124-0QC02-4AX1 is a Siemens SIMATIC-series HMI panel, order code 6AG1124-0QC02-4AX1, supporting 16,777,216 colors across its display and equipped with two communication ports. It includes CSS, RDB, TXT, and XML capabilities, plus RAM for data handling, and is rated IP20 for in-cabinet mounting. Physical dimensions are 331.2 mm wide, 207 mm high, and 75 mm deep, with a weight of 7260 g.
Function & operation
This HMI panel serves as the operator interface for machine control and process visualization. The 16,777,216 color depth provides clear, high-contrast graphics for alarm pages, trend displays, and machine status screens. The two ports support multiple protocols including Modbus, MPI, PROFINET with IRT, MRP, and AB DF1, allowing connection to a wide range of PLCs and drives without additional gateways. Built-in support for CSS, RDB, TXT, XML, and CSV file handling enables recipe management, data logging, and report generation directly from the panel. The unit includes a web server (HTTP/HTTPS), DHCP, SNMP, and LLDP for network integration, and supports WinAC for soft-PLC runtime. An integrated USB port and flash memory facilitate project transfer and firmware updates. The panel does not include a Java VM, power measurement, or an audible buzzer, but it does support alarms and arrays for data handling.
Applications
The 6AG1124-0QC02-4AX1 is used in machine building, packaging lines, material handling, and process skids where an operator panel is needed for local control and visualization. Its protocol breadth makes it suitable for multi-vendor environments — connecting to Siemens S7, Modbus RTU/TCP slaves, Allen-Bradley CompactLogix via DF1, or third-party drives over PROFINET. The IP20 rating limits it to clean, dry cabinet installations, not washdown or outdoor locations.
Market & positioning
Within the Siemens SIMATIC HMI family, the 6AG1124-0QC02-4AX1 sits as a mid-range panel with extensive communication options, targeting applications that need more than basic touch control but do not require the high-end multi-touch or large-format panels. It competes with other 15-inch class HMIs from Rockwell, Beckhoff, and Weintek, but its native support for PROFINET IRT and MPI gives it an edge in Siemens-centric architectures.
