Product Overview

The 6AV6645-7AB10-0AS0​ is Siemens’ SIMATIC Mobile Panel 177 PN — a 6-inch portable HMI pendant designed for machine-level remote operation where the operator needs to leave the fixed control cabinet and walk along the equipment. As the PROFINET variant of the Mobile Panel 177 family, the 6AV6645-7AB10-0AS0​ brings a 6″ TFT display (64 K colors, QVGA 320 × 240), an analog resistive touch layer, 8 freely assignable soft keys, a numeric keypad, cursor keys, a 3-position enable switch and a red emergency-stop mushroom — the classic European machine-tool pendant ergonomics, engineered into a Siemens HMI running Windows CE 3.0 / WinCC Flexible firmware. The “0AS0” suffix indicates the version with integrated rechargeable Li-ion battery pack, enabling cordless operation during a shift before docking back into the transfer box for charging and wired PROFINET continuity.

In the automation stack, the 6AV6645-7AB10-0AS0​ acts as a PROFINET IO device, meaning it slots directly into a SIMATIC S7-1200, S7-1500, S7-300 or S7-400 PROFINET controller project inside TIA Portal (or STEP 7 + WinCC Flexible 2008 SP3 for legacy). The panel talks HMI tags over PROFINET IO cyclic data, not just a passive display — the soft keys, E-stop and enable switch are wired through the panel’s safety/IO mapping so the controller knows exactly which pendant button was pressed and whether the enable is depressed. The spiral tether connects the 6AV6645-7AB10-0AS0​ to a separately ordered transfer box (6AV6671-7AB00-0AX0 for PN), which supplies 24 V DC and breaks out the PROFINET RJ45. When docked, the panel charges and runs wired; when undocked (battery version), it runs cordless for ~8 hours typical, letting the operator walk the ~2.5 m tether slack or fully wireless if the cell permits. Though the Mobile Panel 177 line has transitioned into the newer Mobile Panel Comfort / Unified path, the 6AV6645-7AB10-0AS0​ remains a heavily specified spare on installed machine-tool, press-brake and assembly lines where requalifying a new pendant triggers a CE/validation cycle the OEM prefers to defer.

Technical Specifications

Main Features and Advantages

The 6AV6645-7AB10-0AS0​ is purpose-built for the “walk-the-machine” operator scenario that a fixed TP700 on a swivel arm cannot serve. The 6″ TFT at 64 K colors is deliberately modest — enough to render tag values, alarm lists, small P&ID snippets and soft-key legends crisply under workshop lighting, without the cost or power draw of a 16 M-color Comfort screen. The analog resistive digitizer registers through industrial gloves and survives the occasional bump against a machine-frame edge; the 6AV6645-7AB10-0AS0​ is meant to be handled, not just viewed.

Ergonomics are where the panel differentiates from stationary HMIs. Eight soft keys sit below the screen, dynamically labeled by the WinCC Flexible project so the same pendant can serve a press-brake setup screen one moment and a servo-homing screen the next. The numeric keypad with sign and decimal lets the operator enter setpoints without opening a full-screen pop-up keyboard — a small detail that shaves seconds per adjustment on busy lines. The 3-position enable switch (dead-man style) and red E-stop mushroom are hard-wired through the panel’s IO mapping to the PROFINET IO bundle, meaning the controller sees enable release and E-stop actuation in the same PROFINET IO cycle that carries HMI tag updates — not a separate safety circuit, though for full ISO 13849 / SIL ratings many integrators still duplicate the E-stop onto a safety relay. The 6AV6645-7AB10-0AS0​ itself is not a safety-rated device, but the wiring path is there for the integrator to use.

Battery vs. tether balance matters. The “0AS0” battery version of the 6AV6645-7AB10-0AS0​ gives roughly a full shift of cordless runtime (Siemens quotes ~8 h typical, depending on backlight level and PROFINET traffic). When the operator returns to the transfer box, the panel docks magnetically/mechanically, charging resumes automatically and the PROFINET link stays alive through the box’s RJ45 uplink. For plants that prefer never-untethered (continuous charging, zero battery aging concern), the “0AE0” no-battery sibling exists — but the 6AV6645-7AB10-0AS0​ is the one that shows up on most BOMs because the cordless minute at tool-change or die-setup pays for itself daily. The spiral cable from transfer box to pendant gives ~2.5 m reach; the operator can walk the full length of a press brake or around three sides of a test rig without the panel leaving hand.

PROFINET IO integration is straightforward: the 6AV6645-7AB10-0AS0​ GSDML drops into TIA Portal or STEP 7, the HMI tags map to the controller’s DB/PII/PQW exactly like a fixed Comfort panel, and WinCC Flexible 2008 SP3 handles the screen project. The pendant supports scriptable VBScript subsets, alarm buffering, recipe storage in the panel’s user memory, and multi-language projects — 5 online languages typical, expandable via WinCC Flex licensing. For S7-1200/1500 greenfield, Siemens nudges toward the newer Mobile Panel Comfort (6AV2125-…), but the 6AV6645-7AB10-0AS0​ remains the drop-in spare for hundreds of S7-300/400 machines where the project is WinCC Flex and the transfer box is already mounted.
