Siemens SIMATIC HMI 6AV3607-1JC20-0AX1 (OP7 DP) – Compact Operator Panel for PROFIBUS/MPI control

The Siemens 6AV3607-1JC20-0AX1 is widely recognized as the SIMATIC HMI OP7 DP variant—typically used as a compact keypad operator panel on S7‑300/400 lines over MPI/PROFIBUS DP. It’s a straightforward, durable text HMI with a monochrome backlit display and hard keys that operators can use with gloves. One thing I appreciate is how easily it drops into legacy panels as a like‑for‑like spare, while still being simple to back up with ProSave and maintain over years of service.

Our Order Process & Guarantees

• Warranty: 365 days
• Lead time: In‑stock items ship in about 1 week; no more than one month at the latest
• Payment: 50% advance; full balance prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• PROFIBUS DP / MPI connectivity – Suits S7‑300/400 cells; stable RS‑485 physical layer, typically up to 12 Mbit/s on DP.
• Rugged keypad operation – Tactile keys for setpoints, mode selection, and acknowledgment; operators don’t need a touchscreen.
• Text display with backlight – Clear alarm and status messages in low‑light environments; practical on older cabinets.
• ProTool/Pro configuration – Projects are usually built in ProTool/Pro; backup and restore via ProSave keeps downtime low.
• Front IP65 ranking – When correctly panel‑mounted, the front withstands wash‑down splashes and dust in most shop‑floor conditions.
• 24 V DC power – Common industrial supply; easy to integrate with standard cabinet power buses.
• Maintenance‑friendly – Typical spares strategy: keep one programmed unit on the shelf and swap within minutes if needed.

Technical Specifications

Application Fields

You’ll typically find the OP7 DP on legacy or cost‑sensitive machines where reliable keypad entry is preferred over a touchscreen:

• Packaging and labeling machines (format changeovers, counters, alarm resets)
• Material handling, conveyors, and palletizers (mode selection, diagnostics)
• Pumps, compressors, and utilities skids (start/stop, setpoint entry)
• HVAC/process auxiliaries around S7‑300/400 control islands

A maintenance manager at a food plant told us they swapped this exact model into an S7‑300 line and were “back in production within the hour” after restoring the ProSave backup—no PLC changes needed.

Advantages & Value

• Procurement continuity – Ideal as a direct spare for installed OP7 DP fleets, minimizing engineering rework.
• Compatibility – Works with SIMATIC S7‑300/400 via MPI/DP; straightforward message‑based HMI.
• Low total cost – No need to redesign cabinets; existing wiring and cutout are typically retained.
• Serviceability – Projects can be archived, restored, and migrated with standard Siemens tools.
• Operator acceptance – Physical keys are preferred in many cases where gloves, dust, or vibration are present.

Installation & Maintenance

• Cabinet & mounting – Panel‑mount on a flat, rigid door; ensure gasket compression for IP65 at the front. Allow clearance at the rear for wiring and heat dissipation.
• Power & protection – 24 V DC supply, SELV/PELV; use a dedicated fuse or circuit protection and proper grounding to reduce noise.
• Fieldbus wiring – Use shielded PROFIBUS cable with correct 150 Ω impedance; terminate the segment at both ends and keep stubs short.
• Commissioning – Load or back up projects with ProSave; configuration projects are typically created in ProTool/Pro.
• Routine care – Keep the keypad and bezel clean; check fieldbus connectors and terminators; schedule backups after any project change.
• Firmware/backup – Maintain a verified image on a service laptop; test restore on a spare unit when possible.

Recommended Accessories & Compatible Parts

• 6ES7901-0BF00-0AA0 – PC Adapter (RS‑232) for MPI/DP access; handy for service and backups on classic systems.
• 6XV1830-0EH10 – PROFIBUS DP cable (violet) for reliable RS‑485 networking in cabinets and on machines.
• 6ES7972-0BA52-0XA0 – PROFIBUS connectors with built‑in terminator; simplifies on‑site diagnostics and service.

If your process requires point‑to‑point serial (PPI/TTY) instead of DP/MPI, the OP7 PP variant is usually the better match; the 6AV3607-1JC20-0AX1 here is the DP‑focused model.
