What is 6AV3607-1JC20-0AX2 and where is it used?
The SIEMENS 6AV3607-1JC20-0AX2 is a SIMATIC OP7/DP operator panel, designed for classic text-based machine operation in legacy automation systems. It is intended for use with SIMATIC S7 and M7 controllers and communicates via PROFIBUS-DP at 1.5 Mbaud.
It is typically used in machines where the original operating philosophy is intentionally kept simple and unchanged: fixed keys, clear text messages, direct acknowledgement, and basic input functions without graphical visualisation. For maintenance and procurement teams, this is especially relevant when a 1:1 or near 1:1 replacement is required to minimise downtime without changing the existing HMI concept.
Overview of key technical data and what it means
The OP7/DP uses a LC display with LED backlight, showing 4 lines with 20 characters each. It is operated via a key-based interface, including system keys, function keys, and two softkey rows typical of the OP7/OP17 family.
In practical terms, this means the device is optimised for compact message display, status indication, setpoint entry, and simple operator sequences, even in machines that do not require graphical HMI systems.
With a weight of approximately 0.498 kg, UL/CSA certification, and a clear focus on S7/M7 environments, the panel is designed for long-life industrial use where compatibility is more important than modern visualisation capabilities.
Product status, life cycle status and obsolescence
According to EICHLER data, this specific MLFB has an EOP (End of Production) status as of 26.06.2008. This places the 6AV3607-1JC20-0AX2 clearly in the category of obsolete or discontinued legacy products.
For modernization planning, Siemens documents the OP73 and OP77 series as successors to the older OP3/OP7 text panels. Migration to WinCC flexible also describes an automated panel replacement path from OP7 to OP77B, with OP77A as an alternative option that may require additional adjustments.
This is not a direct 1:1 successor for the same order number, but it represents a validated migration path defined by the manufacturer for system upgrades.
Available EICHLER services and when they are relevant
For the 6AV3607-1JC20-0AX2, EICHLER offers repair, exchange, used units, and new units on request.
Repair is especially suitable when the existing installation, wiring, project configuration, and operator logic must remain unchanged. EICHLER combines this with technical cleaning, preventive maintenance, full functional testing, and at least a 24-month warranty.
An exchange unit is the fastest option when production must be restored immediately and downtime is critical. Used devices can be economically attractive for short-term availability of obsolete hardware. A test report supports commissioning, quality assurance, and documented restart of the system.
| Fault description | Possible solution |
|---|---|
| Why does my OP7/DP no longer show values or report a PLC communication failure? | First check the cabling, connectors, interface used, and bus parameters. Siemens lists typical causes for messages such as 150000 or 280004, including defective cables, a non-responsive PLC, incorrect interface selection, wrong baud rate, or incorrect HSA or station address. Therefore, verify the physical bus, the configuration in ProTool, and ensure the CPU is in a running state. |
| Why does the transfer to my OP7 fail with a timeout? | For the OP7, a properly configured transfer path is essential. The panel must be in the correct transfer mode, cables and adapters must be stable, and interface settings must match. In practical cases, transfer timeouts are often caused by an incorrect transfer mode or unsuitable PC connection. Additionally, SPS-Forum discussions note that OP7/OP17 devices do not use a true PROFIBUS-DP transfer configuration in the same way as modern panels, so the correct serial or PG/PC communication setup must be ensured. |
| Why does the OP7 display “Protocol error 0003” or E4021? | These errors usually indicate an unstable or incompatible communication link. Siemens identifies causes such as incorrect baud rate, wrong bus parameters, address conflicts, and improper interface selection. SPS-Forum cases show that such errors are often related to faulty cables or adapters. Therefore, check cable type, adapter, COM interface, HSA, station address, and project configuration before assuming a hardware defect. |
| Why does my OP7/DP keep restarting? | Repeated restarts are often not caused by a defective panel but by wiring or connector issues on the bus. Documented OP7/OP27 cases show that swapped bus wires, invalid connection between data line and ground, or poorly seated PROFIBUS connectors can trigger this behaviour. Check A/B lines, shielding, connector integrity, and 24 V power supply. In older installations, also inspect for ageing connectors and contact instability. |
Is 6AV3607-1JC20-0AX2 still a sensible solution for legacy systems today?
Yes, especially when the installation cut-out, project configuration, key logic and operating procedures are to remain unchanged. In exactly these cases, a classic OP7/DP is often more economical than a full HMI redesign. Instead of cabinet modifications, project migration and recommissioning, a suitable replacement or repair can bring the system back into production significantly faster. This is particularly relevant for machines with fixed start/stop/acknowledge logic and text-based operation, where the device therefore remains important for procurement and spare parts strategies.
Is there a direct successor for 6AV3607-1JC20-0AX2?
You should not assume a clearly defined 1:1 successor for the same order number. However, Siemens positions the OP77B as the graphical successor to the OP7 and specifies that it uses the same installation cut-out and offers a high level of compatibility. Siemens also documents the OP77A and OP77B as successors of the OP7 generation and confirms migration capability for existing OP7 projects. For procurement this means: for a pure spare parts strategy, stay with the exact OP7/DP; for modernisation, evaluate migration to OP77B or OP77A.
Can an existing ProTool project be reused?
Yes, but usually not without some adjustments. Siemens describes OP7 project migration via WinCC flexible, where an OP7 project is typically converted into an OP77B configuration. After migration, screens, key assignments, system functions and layout must be checked, as not all legacy mappings are transferred one-to-one. This is particularly important for system and function keys where PLC bits are directly controlled from the HMI. Existing engineering work can therefore be reused, but a technical review after migration remains essential.
Which software is required for modifications or migration?
The original engineering environment for the OP7 comes from ProTool / ProTool Lite, including the OP7/OP17-specific key and softkey concepts. If an existing project is to be migrated to a newer HMI platform, the official path is migration to WinCC flexible. For procurement and maintenance teams, this is important because hardware replacement alone is not sufficient: without access to the correct project and engineering environment, any modernisation quickly becomes more expensive and time-critical.
When is repair more suitable than replacement for this panel?
Repair is particularly suitable when the system must be restored quickly but the installation cut-out, wiring, project status and operating philosophy are to remain unchanged. At EICHLER, repair includes technical cleaning, preventive maintenance, functional testing and a minimum 24-month warranty. Replacement is usually the better option when the unit is severely damaged or when a working spare is required immediately. From a commercial perspective, repair is often the lower-risk option when an obsolete device still needs to be secured in service.
How can I tell whether my system really requires the OP7/DP and not another OP7 variant?
The decisive factors are the exact order number, existing wiring and project configuration. The 6AV3607-1JC20-0AX2 is the DP variant for SIMATIC S7/M7 systems with PROFIBUS-DP at 1.5 Mbaud. Even a seemingly similar OP7 version with a different interface or project basis can cause issues during commissioning, transfer and communication. For reliable identification, the nameplate, project file, bus topology and PLC connection should always be checked together. In legacy systems, this detailed verification often determines whether replacement takes hours or several days.
