You will now create all the required wiring that constitutes Loop 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 Plant Panel Manager, create new Junction Box 101-JB-PLC-001 by duplicating 101-JB-DCS-001.

2. In the Plant Cable Manager, create new Multi-Cable C-101-JB-PLC-001 by duplicating Cable C-101-JB-DCS-001/1.

3. In the Plant Panel Manager, create a new PLC with one I/O rack and name it 101-PLC-001. (See Task 4 on page 151 and Task 5 on page 155 for further details of how to do it.) On the Control System tab, from the System I/O type list, select AI.

4. Add a new I/O card to the PLC using the following definitions:

a) In the Strip Terminal Configuration dialog box, configure the I/O card to have 8 channels with 3 terminals per channel.

b) Name the new I/O strip 1/3 (8A/I).

When expanding the strip in the Panel Manager, the terminals should be numbered as shown.

5. Assign Tag 101-FT-201 to I/O card 1/3 (8A/I), Channel #1. (See Task 9 on page 179 to learn how to do it.)

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

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

a) Using the 2 TERMINALS+SHIELD configuration, configure the strip to have 16 blocks of terminals with 3 terminals per block.

b) Name the new strip FT-JB-001.

When expanding the strip in the Panel Manager, the terminals should be numbered as shown.

8. Add a new strip for the PLC side of 101-IR-002 using the following definitions:

a) Configure the strip to have 8 blocks of terminals with 2 terminals per block.

Create the following configuration as a basis:

b) Name the new strip TP-AI-1/3.

c) Delete the superfluous terminals that you created by using the 16-pair configuration.

When expanding the strip in the Panel Manager, the terminals should be numbered as shown.

9. Make the following connections in Junction Box 101-JB-PLC-001, Strip TS-1:

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

b) Connect Cable C-101-FI-201 starting at Terminal 7+ at the left side of the strip using 3 in a row as the connection type.

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

10. Scroll down to view the connections at Terminals 6+ to 7- and note the signal propagation in the wires at the right side of the terminal.

11. Select Cable Set Pr 7 with wires connected on the right side of the strip and disconnect this set.

12. 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.

13. Add a jumper between Terminals 6- and 7+ on the right side of the strip as follows:

a) Click .

The Connect Jumper dialog box opens.

b) Enter information as shown.

c) Click OK.

The connections should appear as shown.

14. Change the signal definition as follows for the wire you moved in step 12:

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

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

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

d) From the Sequence list on the right side, select 3.

e) Click Save.

The dialog box should appear as shown.

f) Click Close to close the Terminal Connection dialog box.

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

16. 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.

17. In the Connect Options dialog box, click OK.

18. Scroll down to view the connections at Terminals 6+ to 7SH.

The window appears as shown.

19. When done, close the Connection window.

20. In the Plant Cable Manager, create Cable 101-IR-PL003 by duplicating Cable C-101-MR-DCS-001. Rename End 1 Location as Instrument Rack and End 2 Location as PLC.

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

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

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

c) In the Wire field, type Overall Shield and under Polarity, select Overall Shield.

In the Plant Cable Manager, the overall shield appears as shown.

22. Connect Cable C-101-IR-PLC-003 between Marshaling Rack 101-IR-002, Strip TP-AI 1/3 and PLC 101-PLC-001, Strip 1/3 (8A/I) with connection definitions as follows:

a) On the marshaling rack side, connect all the cable sets except for OVERALL SHIELD at the right of the strip, using 2 in a row as the connection type.

b) On the PLC side, connect all the cable sets except for OVERALL SHIELD at the left of the strip, using 3 in a row as the connection type.

Note that a signal for Tag 101-FT-201 appears for the first two wires because of the I/O assignment you made in step 5.

c) Disconnect the Shield wire connected to Terminal 3-v.

23. When done, close the Connection window.

24. Select Marshaling Rack 101-IR-002 and cross-wire Strip FT-JB-001, Terminals 6+ and 6- (right side) and 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 FI-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 workout

examples in the tutorial do not use them; nevertheless, you are encouraged to familiarize yourself with these 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 effort. For details, see the relevant section of the Wiring module documentation.

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 checkbox selected, however, without defining a device panel or an instrument cable.
