Siemens 6ED1057-1AA00-0BA0: 2.5 m PC Programming Cable for LOGO! 0BA0–0BA8

Description

Technical Specifications

Main Features and Advantages

One cable, all LOGO! generations.​ The 6ED1057-1AA00-0BA0​ is intentionally backward-forward compatible: it talks to the oldest 0BA0/0BA1 grey-cased LOGO! units still running staircase lighting in 1990s European social housing, and equally happily enumerates a current 0BA8 (12/24 RCE or 230 RCE) on a small-machine OEM skid. That matters because many panel builders keep a mixed fleet—new LOGO! 8 for current orders, legacy 0BA6/0BA7 spares for older service calls—and the 6ED1057-1AA00-0BA0​ covers both without swapping leads. LOGO! Soft Comfort auto-detects the CPU generation on connect, so the cable is genuinely plug-and-play once the USB driver (bundled with Soft Comfort) is installed.2.5 m reach for real-world cabinet geometry.​ Siemens also offers a 0.8 m version of the same cable, but the 6ED1057-1AA00-0BA0​ at 2.5 m is the one field techs actually prefer. Cabinets rarely oblige by placing the LOGO! at the top corner near the door; it’s usually mid-rail behind a contactor bank, and the laptop ends up on a trolley or folding shelf. That extra 1.7 m prevents having to unbolt the LOGO! just to get a notebook close enough, and it keeps the bend radius gentle on the 6-pin header side where the fragile pins live. For service vans that stock one cable per technician, the 2.5 m version is the default choice.USB bus-powered, no wall wart.​ The 6ED1057-1AA00-0BA0​ draws what it needs from the LOGO! programming header and the PC USB port; there is no barrel-jack inline brick, no “don’t forget the 24 V supply” step. On a live panel the LOGO! is already powered from the DIN-rail PSU, so the cable just works. On a bench-test setup with a LOGO! on the workbench, the USB side still powers the cable transceiver while the LOGO! runs off its own 24 V bench supply—no extra clutter.Clean integration with LOGO! Soft Comfort workflow.​ Once the 6ED1057-1AA00-0BA0​ enumerates as a COM port (Windows Device Manager sees it as a Siemens LOGO! USB Cable), Soft Comfort’s “Online / Offline” toggle lets you go from editing ladder/FBD to live monitoring in one click. Variable forcing, I/O state watch windows, and the small-animation mode that blinks the LOGO! LCD remotely all flow through this cable. For commissioning engineers who live in Soft Comfort for three days straight wiring a small-machine sequence, the 6ED1057-1AA00-0BA0​ is effectively part of the IDE.Ruggedized for van-and-panel life.​ The overmolding at both connector ends, the strain relief where the 6-pin pigtail meets the main jacket, and the 2.5 m jacket grade are all spec’d for the tug-and-snag reality of panel-shop floors. The 6-pin female that mates the LOGO! header is the wear item—after a few hundred inserts the latch loosens—but the 6ED1057-1AA00-0BA0​ is cheap enough to rotate as consumable rather than nurse along.

Application Field

The 6ED1057-1AA00-0BA0​ lives wherever LOGO! lives, which is to say everywhere Siemens small-automation footprint reaches: OEM packaging machines, conveyor zone controls, pump alternation panels, small press safety interlocks, HVAC damper/fan sequencing, lighting control (astronomical clock, staircase timer, garden/park switching), door/gate logic, irrigation scheduling, small-boiler burner management, compressor star-delta with timer extension, and the endless stream of “too small for an S7-1200, too smart for a relay” applications that LOGO! was born for. In each of those, the 6ED1057-1AA00-0BA0​ is the commissioning link—downloading the first project, tuning the timer presets on site when the machine builder guessed 3 s and the customer wants 4.2 s, then handing over the laptop and saying “next one.”Building-services contractors are a particularly dense user cluster: German-speaking markets alone have hundreds of thousands of LOGO! units in stratified heating pumps, solar DHW prioritization, stairwell lighting with motion override, and small wastewater lift-station alternation. Every one of those gets touched at least once in its lifecycle by a 6ED1057-1AA00-0BA0—whether at original commissioning, at a tenant-change reprogram, or during a retrofit where the old 0BA4 program gets exported to 0BA8 and re-downloaded. Facility maintenance teams in hospitals, schools, and municipal depots typically stock two or three 6ED1057-1AA00-0BA0​ cables because they migrate between buildings and the cable lives in the laptop bag, not on a fixed bench.Panel shops and OEM skid builders are the other big constituency. A small-machine OEM shipping ten bread-ovens a month will burn through 6ED1057-1AA00-0BA0​ cables on the test bench (one per station) plus keep a spare in each field-service kit. Since the cable is cross-generation, the same part number works on the 0BA6 spares they keep for a 2012 design and the 0BA8 units going on next month’s order—no need to split inventory.
