Description

The SIEMENS 6ED1057-1AA00-0BA0 is the official PC programming cable for the Siemens LOGO! family of intelligent logic modules, designed to establish a reliable physical communication link between a PC (or programming device) and the LOGO! controller . This 2.5-meter cable serves as the essential “handshake” between engineering software and the hardware, enabling program transfer, online monitoring, and system parameterization .

The SIEMENS 6ED1057-1AA00-0BA0 features an RS-232 serial interface (DB9 female connector) on the PC side and a proprietary programming port connector on the LOGO! side . While Siemens now offers a USB version (6ED1057-1AA01-0BA0), the 6ED1057-1AA00-0BA0 remains a crucial accessory for maintaining and servicing legacy LOGO! installations that rely on traditional serial communication .

Application Scenarios

In a food and beverage packaging line in the Midwest United States, an OEM panel builder was commissioning a new conveyor control system based on a Siemens LOGO! 24RC module. The engineer needed to download a ladder logic program from their laptop to the controller but discovered the USB cable was left at the office. A spare SIEMENS 6ED1057-1AA00-0BA0 cable from the maintenance kit was deployed, instantly restoring connectivity. Within minutes, the program was downloaded, the conveyor timing sequences were adjusted online, and the line was running at full speed. The site manager noted: “The SIEMENS 6ED1057-1AA00-0BA0 saved us from a four-hour delay waiting for the right cable. It’s the unsung hero of our LOGO! commissioning work.”

The SIEMENS 6ED1057-1AA00-0BA0 also proves invaluable in legacy system support. Many building automation systems, HVAC damper interlocks, and street-lighting controllers installed in the 1990s and early 2000s still use LOGO! 0BA0–0BA6 modules . When these systems require parameter updates or troubleshooting, the SIEMENS 6ED1057-1AA00-0BA0 is the only reliable way to connect, as newer USB cables may not be fully compatible with older LOGO! firmware revisions .
