Mode of operation Siemens PLT 130 . 1994 2/2 Transfer control, data protection and transfer Transfer control Sequential data transmission systems require a transfer controlunit for organization of the data traffic on the line. This unit orga-nizes and coordinates the data traffic so that only one su...

Mode of operation Siemens PLT 130 . 1994 2/3 Addressing, transmission modes This method has the following important advantages: There is far less loading on the bus system since only theinformation is read from the automation system which is cur-rently displayed on the monitor channelsData need only...

Mode of operation Siemens PLT 130 . 1994 2/4 Redundant operation mode, transmission reliability, synchronization Redundant operation mode The CS 275 bus system can be redundant in order to increasethe availability. The interface modules for the local bus are al-ready designed for a redundant local b...

Mode of operation Siemens PLT 130 . 1994 2/5 Configuring of communication Configuring of communication Since the communication via the CS 275 bus system is handledlike the automation functions via function blocks, they can alsobe configured in full-graphic mode on the screen by means ofthe configuri...

Design Siemens PLT 130 . 1994 3/2 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 enablebus communication,...

Design Siemens PLT 130 . 1994 3/3 Remote range, bus components The following therefore applies:In the case of electrically isolated local bus interface modules,the ground potential of the bus interface is decoupled from theground potential of the subrack system. In addition, the 0-Vlevel of the inte...
