2 FIELDBUS DS00 / DS200 : WIRING ECONOMY AND INSTALLATION FACILITY. A remote control of actuators or any type of equipment based on a two-wire control cable system. The fieldbus DS00 / DS200 is the overall solution which allows a centralised control and monitoring of multiple actuators. The DS00 / DS200 fieldbus was developed with the idea that a data transmission to a field needs a simple and sturdy system which is reliable. Functional and economic, it ensures work safety ; the DS00 / DS200 is the most suitable solution and the most economic. The control station of the DS00 / DS200 fieldbus acts as an interface for systems of upper level : PLC, control rooms, maintenance positions ; it also monitors the connection to actuators. Each actuator is equipped with a bus interface module. LOW COST INSTALLATIONS Reduction of the number of starting lines : one per actuator in conventional installations ; one for a group of actuators with the fieldbus system. Results in important reduced cable installation costs on site. DS00 / DS200 - FIELDBUS FLEXIBILITY The two-wire connection on actuators is simple and fast. Locally, the system may be extended by connecting a supplementary unit on the line. Easy installation and low cost connection. Long lengths of lines is possible without loss of response time (up to 0 km from starting line). TEST AND SERVICING FACILITIES Small pocket sized controllers make it possible to either monitor the commands which circulate in the bus system or to fit a field unit on an actuator. Signs are alphanumeric without necessary programming and may be used by non specialists.
4 VARIOUS POSSIBLE CONNECTIONS A COMPACT INTERFACE FOR ACTUATORS Each actuator is equipped with a bus interface. This compact sized module transmits open, close, commands as well as signalling valve open and valve closed. The motorised valve is permanently under control ; any eventual malfunctioning is immediately reported. The bus interface module takes up very small space and can be fitted in all of our integral version actuators. MULTIPLE CONNECTIONS These modules are easy to accommodate so as to create personalised connections. All sensors or motors may be connected : pressostat, pump controls, actuators already installed on site, etc.. The field modules are widely diffused and may be acquired from an independent source other than L. BERNARD thus the bus system is an «OPEN» fieldbus easily available. Examples of modules directly connected to fieldbus : ON-OF duty module, to 8 inputs (potential-free contacts) ON-OFF duty module, to 8 outputs per relay Analogue module 4-20mA input Analogue module 4-20mA output Control boxes with pushbuttons and signalling devices may be integrated and connected anywhere on the bus so as to pilot a unit belonging to the same bus loop.
5 A MEDIA PROTOCOL FOR DIALOGUE WITH PLC Communication between the controller DS00/DS200 and the PLC of higher level are assured through RS422 or RS485 links. The media protocol is MODBUS with a transmission speed of 9600 baud. Selection of address on the controller by miniswitches offers the possibility of connecting various controllers on the same media line (multidrop). Emergency shut down (optional) : By opening an external switch, a choice of motorized valves is driven in fail safe position. Each actuator can be configured to open or close the valve. OPTIMUM SECURITY WITH REDUNDANT FIELDBUS Owing to its construction technics, the fieldbus DS00 is liable and robust. However, to guaranty a continuous functioning of the system, even inspite of a line break, the use of a double command technic is the most efficient. The controller DS200 is the solution and works in the following manner : All circuits - the bus controller, the starting line fiber optic connections and each bus line - are doubled. MODBUS MODBUS 2 CONTROLLER To the start of line A CONTROLLER 2 To the start of line B The bus controllers may receive one or two MODBUS protocols. Each controller is separate and has a permanently updated data base. Mutual surveillance of each controller is achieved through optocoupled connections. Each actuator receives information either from line A or line B. ACTUATOR The surveillance of each bus line A or B is permanent and in case of malfunctioning, actuators are automatically commuted to the operational line. The malfunctioning is immediately reported on the front side of the principal rack and unto the PLC. LINE A LINE B
6 RAPID PERFORMANCE The processing system s speed allows for high safety while monitoring and controlling all information statements treated in a particularly short lapse of time. The fieldbus DS00 / DS200 response lapse time is independent of the length of the loop. The time lapse depends only on the number of bus lines connected to single or redundant control type. The time lapse specified in the chart corresponds to the number of lines and takes into consideration the whole of the system from the time an order is sent through the MODBUS protocol to the actuator s actioning itself. For example, an installation equipped with a controller DS200 including 00 actuators installed on 5 fieldbus redundant loops over a distance up to 0 Km, will require,2 seconds for updating of all data.
