USBMPI Magnetic Isolation Cable — Industrial Grade (Model 6ES79720CB200XA0) — Black Why this cable matters Designed to provide a stable, noiseresistant link between a PC and Siemens S7 series PLCs and OP/TP touch panels. Magnetic isolation helps protect both your programming device and the control network from electrical interference and ground loops common on industrial floors. Ideal for commissioning, programming, diagnostics, and HMI configuration where reliable communication and equipment protection are essential. Key benefits Protects equipment: Magnetic isolation reduces the risk of damage from transient voltages and ground potential differences during data transfer. Improves communication reliability: Industrialgrade construction and interference suppression deliver more consistent connections in electrically noisy environments. Broad compatibility: Works with S7200, S7300 and S7400 PLC families and supports OP/TP touch panel HMI connections for programming and troubleshooting. Easy to use: Connects a PC to the MPI network for software tasks such as programming, parameter changes, and diagnostics. Main features and attributes Model: 6ES79720CB200XA0 Functionality: USBtoMPI communication cable with magnetic isolation to separate PC host from MPI network electrically. Compatibility: Supports Siemens S7200 / S7300 / S7400 PLCs and OP/TP touch panel HMI devices that use an MPI interface. Build quality: Industrialgrade construction suitable for factory and workshop environments; finished in black for discreet, professional installation. Performance: Designed for stable data transfer and noise suppression in industrial control setups. Connectors: USB connector on the PC side and MPI connector on the PLC/HMI side (cable configured for standard MPI communication). Typical applications and use cases Commissioning and programming: Use during PLC program upload/download, firmware updates, or parameter setting on S7200/300/400 controllers and connected OP/TP HMI units. Maintenance and diagnostics: Connect a laptop to the MPI network on the machine floor to run diagnostics, read diagnostic buffers, monitor variables, and troubleshoot communication issues while minimizing interference risks. Factory integration and testing: Ideal for system integrators and technicians who need a reliable, electrically isolated link when testing or integrating control systems with sensitive equipment nearby. Why choose this cable Targeted for industrial environments where electrical noise and grounding differences are common. Provides an efficient, safer way to connect programming devices and HMIs to Siemens MPI networks without adding complex isolation equipment. Keeps installation straightforward while improving protection and reliability during critical programming and maintenance operations. What to expect in use Clear, repeatable connections for programming and diagnostic sessions. Reduced communication errors related to electrical interference. Durable performance in typical industrial and workshop settings when used as a direct MPI programming/communication cable. Note: Cable is specified for MPI communication with S7200/300/400 PLCs and OP/TP touch panel HMIs under model number 6ES79720CB200XA0. Ensure device compatibility and software settings for MPI communication prior to use.
