8.1 Module Overview
Introduction
“SIMATIC TOP connect” denotes components for wiring digital modules.
“SIMATIC TOP connect TPA” denotes components for wiring analog modules.
Wiring
Wiring with SIMATIC TOP connect/... TPA is a fast and cost-effective alternative to
conventional wiring of the actuators and sensors directly at the front connector of
the module. When using these components, you wire actuators and sensors “in
situ” on one more terminal blocks. You establish the connection to the module by
means of a connecting cable (round-sheath ribbon cable).
Configuration of SIMATIC TOP connect with a S7-300
A SIMATIC TOP connect and a SIMATIC TOP connect TPA always consist of:
• A front connector module with flat ribbon connection ,
• One or more terminal blocks and
• One or more connecting cables with plug-and-socket connectors at ends
