SIEMENS 6AV3627-1JK00-0AX0

What is 6AV3627-1JK00-0AX0 and where is it used?

The 6AV3627-1JK00-0AX0 is a SIEMENS SIMATIC HMI Operator Panel OP27 featuring a monochrome STN LCD display and a fixed keypad. The device belongs to the class of traditional operator panels used in machines and systems where operators enter setpoints, acknowledge alarms, manage recipes and monitor process conditions. Thanks to the combination of a graphical display and dedicated hardware keys, the OP27 is particularly suitable for legacy systems with a robust operating concept, such as those found in packaging machinery, conveying technology, machine tools and process engineering applications. For maintenance and purchasing departments, the exact part number is critical, as existing machines often require not only the correct form factor but also matching interfaces, project compatibility and spare-parts strategy.

Overview of the key technical specifications and their significance

The OP27 features a 5.7-inch display with a resolution of 240 × 320 pixels and 8 grey levels. In everyday industrial operation, this provides good readability for traditional process screens, alarm messages and parameter pages, although the display capabilities are naturally not comparable to those of modern HMI systems. The panel includes 24 function keys, of which 18 are equipped with LEDs, as well as 24 system keys and support for numeric, alphanumeric and hexadecimal input. For integration into older automation environments, the available TTY, RS232, RS422 and RS485 interfaces are particularly important. Additional features include 1 MB of application memory, a PC card slot, IP65 protection on the front panel, and a typical power consumption of 8 W. These characteristics are often decisive factors in retrofit and replacement projects.

Product status, life-cycle status and obsolescence status

The 6AV3627-1JK00-0AX0 is considered a significantly obsolete legacy device. The EICHLER product page lists the unit with EOP (End of Production) status dated 01 April 2006. A Siemens datasheet additionally classifies the assembly as a discontinued product and states end of PLM and support effective from 01 October 2015. A Siemens product directory further indicates that no direct replacement product is assigned to this part number. While Siemens support documentation occasionally references the OP270 and later the OP277 as possible migration paths, these should not be regarded as verified one-to-one replacements for every application. For operators, this means that long-term availability today is primarily ensured through repair services, exchange units, used-device availability and a well-structured asset management strategy.

Available EICHLER services and when they are relevant

Several practical service options are available from EICHLER for the OP27. Repair services are particularly suitable when the existing project configuration, wiring and mechanical installation need to remain unchanged and downtime must be kept predictable. EICHLER specifies a typical turnaround time of 1–3 days and includes services such as technical cleaning, preventive maintenance, comprehensive functional testing and a minimum 24-month warranty. An exchange unit may be the preferred option when a rapid return to operation is more important than repairing the original device. In addition, used devices with short delivery times and new devices on request are available. The optional test report supports purchasing departments, quality assurance teams and decision-makers by providing documentation and reducing operational risk, particularly in situations where obsolescence management has become a critical issue.

Is 6AV3627-1JK00-0AX0 still available or only obtainable as a legacy part?

The device is no longer a current production product. Siemens classifies this part number as discontinued and as a product that has reached the end of PLM and support, while EICHLER also lists it with EOP (End of Production) status. In practical procurement terms, however, this does not necessarily mean that the device is unavailable. For this assembly, EICHLER offers repair services, exchange units and used devices with short delivery times, while new devices are only available on request. For purchasing and maintenance teams, the key question is therefore not simply "new or used?", but rather which solution will return the system to operation most quickly and with the lowest risk.

Is there a direct successor for the Siemens OP27 Mono?

A directly verified one-to-one successor for the 6AV3627-1JK00-0AX0 is not specified in the manufacturer sources reviewed. A Siemens product directory explicitly states that the product is listed without an assigned replacement product. Although Siemens support discussions mention the OP270 and later the OP277 as potential migration paths, these references do not replace the need for a technical evaluation of the specific application. Critical factors include the project configuration, mounting cut-out, interfaces, power supply, operating concept and machine approval requirements. Operators of existing systems should therefore clearly distinguish between a full retrofit, a replacement using the same form factor, and a repair of the existing panel.

Which software do I need for the OP27?

The OP27 is configured using ProTool. The EICHLER product page specifies ProTool Version 3.1 or later as the required engineering software. Siemens documentation relating to later ProTool versions also describes the possibility of converting existing graphics-device projects, which is particularly relevant for migration projects. For routine service work on an existing OP27, however, the most important factor is the availability of the original or compatible legacy engineering environment. Simply replacing the device without correctly transferring the project may result in communication issues, incorrect key assignments or unsuccessful project downloads. In legacy installations, securing the project files is often just as important as sourcing the replacement hardware itself.

How can I back up project data or recipe data on the OP27?

Siemens provides a backup and restore function via memory card for the OP27. The memory card is inserted into the designated slot, after which a backup can be initiated from the standard screen. The device manual also describes the restoration of recipe datasets, firmware and project data. For operators of older systems, this is a critical precautionary measure. Before any repair, replacement or troubleshooting activity, the current project configuration and all production-relevant datasets should be backed up. This helps prevent situations where the panel itself is operational again after hardware replacement, but recipes, settings or the functional visualisation project are missing.

Which interfaces does the OP27 provide, and why is this important for repair and replacement?

According to the technical specifications, the OP27 is equipped with TTY, RS232, RS422 and RS485 interfaces, as well as a PC card slot. These legacy interfaces are often the most critical factor in existing installations. A mechanically compatible replacement panel offers little benefit if the protocol, connection method or project configuration does not match the machine. For maintenance personnel, it is therefore essential to verify not only the part number, but also the actual communication setup of the machine: Which controller is connected? Which interface is in use? Which protocol is running? How is the project transferred? The answers to these questions determine whether a repair, exchange unit or retrofit can ultimately be implemented successfully without extended downtime.

When is repair more economical than replacement?

For obsolete HMIs, the most cost-effective solution is rarely universal. Repair is usually the preferred option when the existing project configuration must be retained and preserving the original device provides the fastest route back into production. An exchange unit is often more suitable when an immediately operational replacement device is required. EICHLER specifies turnaround times of 1–3 days for both options and supplements its repair service with technical cleaning, preventive maintenance, functional testing and a minimum 24-month warranty. For decision-makers, the relevant factor is therefore not merely the purchase price, but the overall balance of downtime costs, integration effort, project migration risk and long-term spare-parts strategy. For organisations operating multiple OP27 units, a planned combination of repair capability and strategic stockholding is often the most robust long-term solution.
