Schneider Electric 140-CRP-811-00 Profibus DP Master Module

Schneider Electric 140-CRP-811-00 Profibus DP Master Module is a Class 1 Profibus DP master card for the TSX Quantum automation family, designed to connect a Quantum CPU to Profibus DP slaves. The module provides an RS-485-based Profibus DP master interface via a bus tap and is intended to install in a Quantum backplane to drive DP communications across the network. In Profibus DP networks, this master module can operate as the primary master, coordinating cyclic data exchange with connected DP slaves; networks can be configured with either a single master or multiple masters depending on the system design. The 140-CRP-811-00 is documented as a Profibus DP master option within Quantum configurations, and Schneider notes that the maximum number of communication option modules (including the CRP family) depends on the CPU/backplane used. Typical use cases include integrating factory automation field devices and modular I/O into a Schneider Quantum control scheme, with configuration performed via Schneider’s System Configurator/Concept software and with a station address assignment as part of the DP master setup.
