Siemens 6ES5712-8AF00 Interface Cable

Engineered for SIMATIC S5 Programmer Connections

This cable connects an S5 CPU to a programming device. It provides reliable data transfer for the Siemens 6ES5712-8AF00 assembly. You will find this interface cable in legacy SIMATIC S5 systems. Unlike standard serial cables, this version uses fully shielded construction. It maintains error-free communication over the entire length.

Technical Specifications & Physical Dimensions

We designed this interface cable for industrial programming environments. The table below presents all verified technical specifications.

Functional Architecture and Signal Routing

This cable transfers RS232 signals between CPU and programmer. It uses nine conductors for full handshaking support. You cannot extend the cable beyond 15 meters total length. Moreover, the cable includes a braided copper shield around all conductors. This component blocks external electromagnetic interference effectively. Consequently, the cable delivers error-free data at 9600 baud.

Installation and Operational Guidelines

The Siemens 6ES5712-8AF00 maintains signal integrity up to 60°C ambient. It introduces less than 5 nanoseconds of signal skew. You must align the D-sub connectors with the port orientation. Always secure both ends with locking screws. This practice prevents accidental disconnection during operation. Furthermore, the cable supports both programming and monitoring modes. This feature allows online program changes without reconnecting.

Physical Characteristics and Environmental Limits

This interface cable has a gray PVC outer jacket. Its 24 AWG stranded wires provide excellent flexibility. The layout follows Siemens standard S5 programming specifications. Therefore, it fits any S5 CPU with a 15-pin programming port. The cable requires a 75mm minimum bend radius. In addition, it maintains stable operation between 0°C and 60°C ambient temperature. You can store this cable safely between -25°C and 70°C.
