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.

Testing of conveyor & agitator

On 24th march 2011 we tested conveyor and agitator by changing the contacts manually means without command from slave PLC.   Steps are given below for our existing plant:

1.We traced out the proper wiring ,which MCB(Miniature circuit Breaker) is connected through contactor circuit .Wiring diagram will be soon displyed.
2.  3 cables from the motor are connected to contactor n contactor also got connected to cables from R2 ralay and NO ,NC contacts are 11 & 14 in our panel..
3.contactor has supply from the source through MCB.when operator gives command,command from realys comes to contactor and contacts cganged means star to delta & supply get connected to motor/agitator.This is the logic behind wiring diagram
4.This will more understand when we will disply the wiring diagram of our panel.
conveyor motor was 3 phase,so we have to check safety aspects while working in plants.

Batch reactor daily progress report

1) SOV (Solenoid coil for double acting cylinder which acts as stopper for bottle |& lift the bottle for filling) tested by providing external 230 V A.C..Found OK.

2)Both Cylinders are working properly.

3)Master slave cable tracing done & proper termination done,its tagging is remaining.

Major work to be done in coming days:

1) Conveyor motion to be checked.

2) Limit switch checking

Procedure for checking proximity switch

1.Provide 24 v D.C. supply between 2wires ot of 3(in our case between brown & blue colur cable).
2. On proximity sensor it is clearly mentioned from which cable we get feedback (i.e. digital in) & whre we have   to give 24 v DC.
3.Any metal at specific distance it cheks & gives the feedback..

Batch process field work

Work done on 16/03/2011
1.Today we tested two proximity sensors which are used for position sensing  of bottles on conveyor in batch process loop
2.we noted its connection in B & R PLC panel.

Work to be done :
1.Solenoid coil for air supply of double acting cylinder,if solnoid valve is working then by giving air supply we have to check both solnoid valves workining
(we can check both cylinder by giving direct air supply)
2.Conveyor checking
3. Limit switch
4.Master slave connection
