INTERBUS and INTERBUS Configuration with Momentum 1 Overview Introduction This chapter provides an overview of the INTERBUS and the INTERBUS configuration with Momentum.
General Information about INTERBUS-Configuration General Information about INTERBUS What is INTERBUS? INTERBUS is an open communication standard and is provided by over 200 manufacturers who offer wide range of different products. The high-speed network is used for the connection of I/O modules, sensors, actuators, and control devices to programmable logic controllers or large computer systems. Features of the INTERBUS The INTERBUS is a master/slave network, optimized for efficient I/O data exchange.
General Information about INTERBUS-Configuration INTERBUS Configuration with TSX Momentum General information The INTERBUS consists of remote bus and peripheral bus segments. All bus segments transfer the same signals, but with differing electrical signal levels. Note: TSX Momentum I/O modules can only be used on the remote bus and remote bus branches.
General Information about INTERBUS-Configuration Switching off remote bus branches The INTERBUS can only function properly as a shift register if all bus nodes are present and intact. If one node is switched off or fails, the data transfer is stopped by the bus master. With INTERBUS topologies with branch terminals (see example Construction of a Tree Structure, p.

The ID code provides the INTERBUS master with I/O type data (inputs and/or outputs) and the number of words required by the I/O module in the INTERBUS telegram. After the INTERBUS master has received and evaluated the ID codes from the I/O modules, it automatically begins data exchange in real time.

Data Management and I/O Words Data Management for I/O Units Addressing with digital I/O units The data exchange between the I/O unit and the bus adapter occurs 1:1. With the TSX Momentum digital modules, the I/O points of the peripheral terminals are always mapped according to the following principle: l Only words are mapped to (max. 2 for 32 inputs or 32 outputs). l The most significant word (MSW) is sent or received first.

Data Management and I/O Words Diagnostics Error monitoring 104 The internal voltage supply (Vcc) is supplied by the I/O unit. Vcc is monitored and a reset signal is generated if Vcc is outside the tolerance. The potentially isolated voltage (Vcx) for the INTERBUS interface is generated using a DC/DC converter and is not monitored.
