This catalog is out of date, see note on page 2 Summary The TELEPERM M process control system consists of functionally different components which are optimized for the various problems encountered in process automation. Because of their modular design, these components are also referred to as systems. The TELEPERM M process control system is divided into AS automation systems, OS operation and monitoring systems and CS 275 bus system.
This catalog is out of date, see note on page 2 Summary The bus system can be designed in redundant form if extremely high demands are placed on the availability. This does not result in additional configuring requirements. Events are always recorded with the exact time since the individual bus participants can synchronize their clocks via the bus system. The simple configuring is one of the most important characteristics of the CS 275 bus system.

This catalog is out of date, see note on page 2 Mode of operation Transfer control, data protection and transfer Transfer control Sequential data transmission systems require a transfer control unit for organization of the data traffic on the line. This unit organizes and coordinates the data traffic so that only one subscriber transmits data on the bus at a time. This transfer control function is decentralized in the CS 275 bus system.
This catalog is out of date, see note on page 2 Mode of operation Addressing, transmission modes This method has the following important advantages: There is far less loading on the bus system since only the information is read from the automation system which is currently displayed on the monitor channels Data need only be stored at one position as a result of the distributed data base principle.
This catalog is out of date, see note on page 2 Mode of operation Redundant operation mode, transmission reliability, synchronization Redundant operation mode Time synchronization The CS 275 bus system can be redundant in order to increase the availability. The interface modules for the local bus are already designed for a redundant local bus line. A bus converter UI and a connector board AF are required for connection of a redundant remote bus per remote bus cable.

This catalog is out of date, see note on page 2 Design General notes, local range The CS 275 bus system is physically divided into -- a local range up to 20 m (local bus) and -- a remote range up to 4 km, or up to 12 km with bus couplers. Each participant requires a local bus interface module to enable bus communication, redundant systems such as the AS 235 H automation system require two modules.
This catalog is out of date, see note on page 2 Design Remote range, bus components Bus components Local bus interface modules non-floating The following therefore applies: In the case of electrically isolated local bus interface modules, the ground potential of the bus interface is decoupled from the ground potential of the subrack system. In addition, the 0-V level of the interface logic is matched to the potential of the coupling partner via the local bus cable.
This catalog is out of date, see note on page 2 Design Bus components Connector board AF Bus coupler The remote bus cable is connected to the bus converter via the connector board AF. Autonomous buses are connected together via a bus coupler. Data transfer is then possible between several systems or system areas over larger distances (> 4 km) with decoupling of the data traffic on the buses. The board is provided with a terminating resistor which can be activated using a jumper.
