Design the Wiring for Loop F-201 - Intergraph Smart Instrumentation - Training - Intergraph Process, Power & Marine Documentation

You will now create all the required wiring that constitutes loop 101-F-201. The wiring for this loop is a little more complicated than for the previous example. In particular, you will learn how to create jumpers and how to adjust a signal path definition manually.

1. In the Domain Explorer, create a new junction box 101-JB-PLC-001 by duplicating 101-JB-DCS-001.

    1. On the Terminal Configuration dialog box, configure the terminal strip to have 8 channels with 3 terminals per channel.

    2. Name the new terminal strip TS 1/3 (8A/I).

       When expanding the hierarchy of the terminal strip in the Domain Explorer, the terminals should be numbered as shown:

       

14. In the Domain Explorer, right-click the new I/O card 1/3 (8 A/I) Card, then on the shortcut menu, click Actions and click I/O Assignment.

15. In the I/O Assignment window, assign tag 101-FT-201 to I/O card 1/3 (8A/I), channel #1. Name the CS tag BFT201.

    If Tag 101-FT-201 is not on the list in the Tag List pane of the I/O Assignment window, click and select the Uncoupled tags check box.

16. Create a new marshaling rack and name it 101-IR-002.

17. Add a new terminal strip for the field side of 101-IR-002 using the following definitions:

    1. Create a new terminal strip configuration as shown.

       

19. Create a new terminal strip and name it TP-AI-1/3.

20. Expand the terminal strip in the Domain Explorer and ensure that the terminals are numbered as shown.

    

21. Make the following connections in junction box 101-JB-PLC-001, strip TS-1:

    1. Connect cable C-101-FT-201 starting at terminal 6+ at the left side of the terminal strip using 3 in a row as the connection type.

    2. Connect cable C-101-FI-201 starting at terminal 7+ at the left side of the terminal strip using 3 in a row as the connection type.

    3. Connect multi-cable C-101-JB-PLC-001 starting at terminal 1+ at the right side of the terminal strip. Connect all the cable sets on the JB cable side using 3 in a row as the connection type.

22. View the connections at terminals 6+ to 7- and note the signal propagation in the wires at the right side of the terminal.

23. Select cable set Pr 7 with wires connected on the right side of the strip and disconnect this set.

24. Select the wire connected to the right side of terminal 6- and drag it to the right side of terminal 7-.

    

    Note that the signal propagation changes for this wire after reconnection. You will later change the signal definition for this wire manually.

25. Add a jumper between terminals 6- and 7+ on the right side of the terminal strip as follows:

    1. Click .

    2. On the Connect Jumpers dialog box, enter values as shown.

       

    3. Click OK.

       The connections should appear as shown:

       

26. Change the signal definition as follows for the wire you have moved:

    1. Double-click a screw head on terminal 7- to open the Terminal Connection dialog box.

    2. From the Signal list on the right side, select 101-FT-201.

       

    3. From the Signal Level list on the right side, select 2.

    4. From the Sequence list on the right side, select 3.

    5. Click Save.

       The right side of the Terminal Connection dialog box should appear as shown:

       

    6. Click Close on the Terminal Connection dialog box.

27. Close the Connection window and then reopen it for marshaling rack 101-IR-002, terminal strip FT-JB-001.

28. Connect the other end of cable C-101-JB-PLC-001 to terminal 1+ at the left side. Connect all the cable sets on the MARSHALING cable side using 3 in a row as the connection type.

29. On the Connect Options dialog box, click OK.

30. View the connections at terminals 6+ to 7SH.

    

31. When done, close the Connection window.

32. In the Domain Explorer, create cable C-101-IR-PLC-003 by duplicating cable C-101-MR-DCS-001. Rename End 1 Location as Instrument Rack and End 2 Location as PLC.

33. Add an overall shield to the cable as follows:

    1. Select the cable and add a new cable set to it named Overall Shield.

    2. Select the new cable set and add a new cable wire to it.

    3. Under Wire, type Overall Shield.

    4. Under Polarity, select Overall Shield.

       

34. Connect cable C-101-IR-PLC-003 between marshaling rack 101-IR-002, terminal strip TP-AI 1/3 and PLC 101-PLC-001, terminal strip 1/3 (8A/I) with connection definitions as follows:

       The connection should appear as follows:

       

    3. Open the Connection window for PLC panel 101-PLC-001, terminal strip TS 1/3 (8A/I).

    4. Connect cable C-101-IR-PLC-003 to terminal 1+ at the left side. Connect all the cable sets except for OVERALL SHIELD, using 3 in a row as the connection type.

       The connection should appear as shown:

       

       A signal for tag 101-FT-201 appears for the first two wires because of the I/O assignment you made in step 15.

    5. Disconnect the shield wire connected to terminal 3-v.

35. When done, close the Connection window.

36. Select marshaling rack 101-IR-002 and cross-wire terminal strip FT-JB-001, terminals 6+ and 6- (right side) and terminal strip TP-AI-1/3, terminals +1 and -1 (left side) respectively.

    When done, the cross-wiring connections should be completed as shown:

    

This completes the wiring design for loop 101-F-201.

This completes all the wiring required for this tutorial. We would like to draw your attention to the fact that some functions of the Wiring module were omitted because the examples in the Tutorial do not use them; nevertheless, you are encouraged to familiarize yourself with the following functions:

• Connection Type can be defined by clicking . Simple and complex versions of connection types can be created in a plant related list and reused as required for further automation of the wiring design. For details, read the Define a Connection Type section in the Smart Instrumentation Detailed Engineering Users Guide document.

• General Signals and Tag Signals allow the creation of signals that do not originate from field devices. General Signal refers to a signal that may be associated with several tags, for example, a common power supply. Tag Signal is a unique signal, for example, the digital signal from a cabinet mounted trip amplifier. It will require this device to be listed in the Instrument Index and its profile will have the wiring check box selected, however, without defining a device panel or an instrument cable.
