Delta v explorer
Following are the steps for making 'Control module class' and 'Area in control strategies' :
1. open delta v explorer
2.go to library
3.enter into advance definitions
4.there are many class like equipment module class,control module class,etc
5.right click on it n create new class-eg valve and open it with control studio and take whichever input you required.
Benefits: 1. if u need valve that is DO in area for many times then just darg valve from its class n rename it .
Steps for making area:
1. go to system configurations
2. enter into control strategies
3.right click and make new area.

Discussion regarding DCS and PLC in our case
1.DCS- master
2 PLC- slave
these combination we are going to use to run the plant.
- bottle filling application is on PLC which we are doing
- the major parr as tank level,temparature,mixture content,agitator,mass are controlled through DCS
-so suggest your control strategies.
-regarding basic information or quries post here

Conveyor running on B & R PLC
1.After sucessfuly testing of conveyor by taking its perticular contactor in delta mode manually..now it was time to check it through 24V DO out and relay.
2. Pannel layout is sucessfully done.so we can trace the command cables coming from DO card of B & R PLC through perticular relay.
3. When 24V dc is provided by making force on perticular relay,contactor changes from star to delta and 3 phase supply provided to motor.
4. All Digital Inputs (DI) are tested.They are as follows:
a. Limit switch
b. Proximity switch 1
c. Proximity switch 2
5.Angle valve is tested by providing 24vdc to solnoid coil.
6.Stopper- both cyilnder recive air through 5/2 pilot which pass air when solnoid coil energized by 230 V A.C. supply.It is given through another realy which is not present in panel.Tested it,found ok.
7. Now discussion is running on how should logic work,wheather conveyor should stop when bottle filling is there or it should be continously running.
