Problem Statement
This solution frames a short procedure on how to Connect the DMC3 controller Tags to existing Tags inside the IP21 Database (In this case IP21 will simulate the OPC/DCS system)
Solution
The controller used in this example is a controller from the DMC3 example library. The controller name is COL5X3Local and it contains 5 MVs and 3 CVs. This controller can be found under the following path on the Online Server:
C:\ProgramData\AspenTech\APC\Online\app\col5x3
Consider that this
is originally a CCF controller and need to be imported into DMC3 Builder.
The procedure is the following:
1.- Go to deployment on the controller. You will see the connection grid where are listed all Controller variables and their required parameters. In this case we are going to connect only the MV FIC-2001.SP Measurement Parameter which represents the Reading from the field instrument.
On the IP21 administrator we have already created a tag, named FIC-2001.SP (In the Case of the OPC the parameter should created as well in order to have a connection, otherwise when testing Connection DMC3 Builder will fail showing that the target tag does not exist)
2.- Select the IO device that will be use for the Connection in the case of this example I will use device IOIP21
3.- On the Connection Grid type down all the required information that every field require. In this case for the parameter measurement of the variable FIC-2001.SP we will use the following information:
IO Source: IOIP21
IO Tag: FIC-2001.SP
IO Datatype: Double
4.- If the IO source is correct and the Tag name is correct, we can proceed to do a Test Connection. This feature can be found on the top ribbon of the Deployment node (refer to the previous picture highlighted on yellow).
5.- If the Test connection is successful it will bring back a value (whether it is a numeric value or string) on the Test Value field from the grid and highlight the connection with a green connection marker. In this particular case, we can observe that the value is 2.5, this is because DMC3 builder is reading the default value from IP21 database which is 2.5
6.- Finally, we can deploy the controller and do one more change on the IP21 value just to verify that the Online Controller is taking the correct values from the IP21 Database (OPC).
