Siemens SIMATIC MP370 Touch 12″ HMI 6AV6545-5EA20-0BJ0 (OEM Groninger Edition)
The Siemens SIMATIC MP370 Touch 12″ (MPN: 6AV6545-5EA20-0BJ0) is a high-performance industrial multi-panel engineered for supervisory control, machine visualization, and direct process interaction. Built upon the standard industrial architecture of the 6AV6545-0DA10-0AX0, this specialized OEM version was configured to Groninger engineering standards (Design Version C) for pharmaceutical packaging, sterile filling machines, liquid processing lines, and ruggedized vessel automation systems.
Operating on Microsoft Windows CE, the MP370 combines the robust durability of a dedicated operator panel with PC-like functionality. It is equipped with a 12.1-inch SVGA TFT display (800 x 600 resolution), an analog resistive industrial touchscreen, extensive physical interfaces (MPI, PROFIBUS DP up to 12 Mbit/s, Industrial Ethernet RJ45, RS232/TTY/RS422 serial ports), and internal flash application memory.
The hardware platform is designed to maintain real-time fieldbus polling and continuous graphical representation in harsh electrical environments subject to high vibrational stress, maritime ambient shifts, and continuous mechanical operation.

Frequently Asked Questions
What is the difference between MPN 6AV6545-5EA20-0BJ0 and the standard 6AV6545-0DA10-0AX0?
The 6AV6545-5EA20-0BJ0 is an OEM-specific variation built for Groninger packaging machinery based on the standard 6AV6545-0DA10-0AX0 platform. While internal motherboards, core computing platforms, and I/O communication ports are electronically identical, the -5EA20-0BJ0 variant is custom-badged and was pre-loaded with firmware modifications matching Groninger line architectures. Standard projects from a -0DA10-0AX0 can be deployed onto a -5EA20-0BJ0 unit via WinCC flexible without hardware incompatibilities.
Can I upgrade this legacy MP370 unit to a modern Siemens Comfort Panel?
Yes. The functional migration path for the MP370 Touch 12″ is the Siemens SIMATIC TP1200 Comfort Panel (e.g., 6AV2124-0MC01-0AX0). However, migrating requires recompiling the visualization project from ProTool / WinCC flexible into TIA Portal (V13 through V19) and re-tagging I/O points. If keeping downtime to zero without modifying PLC code is your goal, deploying a reconditioned or surplus direct-replacement 6AV6545-5EA20-0BJ0 is the recommended, drop-in solution.
How do I recover or update the firmware (OS Image) on this panel?
Operating system updates and factory resets are performed using the Siemens ProSave utility. Connect your engineering workstation to the MP370 via a serial RS232 null-modem cable, MPI USB CP5711 adapter, or cross-over Ethernet cable. In ProSave, select the MP370 device profile, navigate to the “OS Update” tab, select the target WinCC flexible image, check “Factory Reset (MAC Address required)” if flashing via Ethernet, cycle 24V DC power, and complete the transfer.
Does the MP370 6AV6545-5EA20-0BJ0 support external data logging?
Yes. Historical alarm logs, audit trails, and process tags can be logged directly to an external CompactFlash card (CF Card Type I/II), a PCMCIA PC Card inserted in the rear expansion slot, or routed to a network-attached storage (NAS) share through the 10/100 RJ45 Ethernet port using standard SMB/CIFS Windows protocols.
