Bus communication

Application

AS 235, AS 235 H and AS 235 K can only be operated on the CS 275 plant bus, but can also communicate with automa- tion systems and operator systems on the PROFIBUS-TM plant bus via a CS-L2 bridge.

This section only describes bus communication with the CS 275 plant bus. A description of bus communication via the PROFIBUS-TMplant bus can be found in Catalog PLT 112.

When planning TELEPERM M systems with the CS 275 plant bus, please observe the TELEPERM M design guidelines in the manual "Information and guidelines for planning, instal- lation and operation", C79000-G8000-C417 (German) or C79000-G8076-C417 (English).

Application

￿The AS 235, AS 235 H and AS 235 K automation systems are connected together and to other automation systems and oper- ator systems of the TELEPERM M process control system via the CS 275 bus in medium-sized and large plants.

Central process control is carried out using the OS 525 and WinCC/TM-OS operator systems. SIMATIC PC or other AT-com- patible personal computers, PG programming devices and computers from other manufacturers can be connected to the bus system for higher-level tasks.

Sequential transfer of data between the individual participants is in time-division multiplex mode. Participants within a local area or a cabinet group are connected over distances of up to 20 m by a local bus. A remote bus connects distributed systems over distances of up to 4 km.

A redundant design of the bus line increases of the availability of the CS 275 plant bus. The remote bus network can be extended to a maximum length of 3 x 4 km using bus couplers.

• a local bus which is always redundant and

 

 

 

 

 

 

 

 

 

 

• a remote bus which can be either of single or redundant

Local range

4 line signals are used in the local range. The data are transmit- ted sequentially on one data line. A second line transmits the clock, the third is used for synchronization. The fourth line is required to switch over data transmission to channel A or B of the redundant local bus. The wired-OR technique is used with the local bus for coupling.

The interface modules for the local bus have a redundant local bus interface. They are connected together with one cable in which the local bus is redundant.

The max. length of the local bus cable is 20 m.
