Using PLC I/O Modules (4:43 min)

Prerequisites

Completion of the Using PLC I/O Modules Lesson

Objective:  In this project you insert a PLC module, adding empty spaces and breaking the module for continuation a few rungs later. Next, you break the module and continue inserting it on a different ladder.

Process:  Insert and Break the Parametric PLC Module

Instructions

1:  If the Project Manager is not displayed, on the Project tab, Project Tools panel, click Manager.

2:  If PLC_Modules_NFPA is the active project, skip to step 6. If it is open but not active, in the Project Manager, do the following:
â–  Right-click PLC_Modules_NFPA.
â–  Click Activate.
â–  Skip to step 6.

3:  In the Project Manager, click Open Project.

4:  Browse to where you installed the exercise files. Select PLC_Modules_NFPA.wdp. Click Open.

5:  From the Projects list, click the expansion node next to PLC_Modules_NFPA to expand the drawing list.

6:  Right-click PLC_Modules_NFPA_05.dwg. Click Open.

7:  Zoom into rungs 514-519.

8:  On the Schematic tab, Insert Components panel, Insert PLC (Parametric) flyout > click Insert PLC (Parametric).

9:  In the PLC Parametric dialog box, do the following:

â–  In the upper-left tree view, expand Allen-Bradley.
â–  Expand series 1771.
â–  Select Discrete Input.
â–  In the Table: Allen- Bradley_1771_Discrete_Input (lower) list box, select 1771-IAD.

â–  Under Graphics Style, click 2.

â–  Click OK.

10:  Select the insertion point for the module on rung 513, below the existing PLC module.

11:  In the Module Layout dialog box, click Allow Spacers/Breaks. Click OK.

12:  In the I/O Point dialog box, do the following:
â–  For Rack, type 1
â–  For Slot, type 2
â–  Click OK.

13:  In the I/O Address dialog box, select I:12/00 from the Quick Picks list. Click OK.

The PLC information symbol and the first I/O point symbol are inserted and exploded.

14:  In the Custom Breaks/Spacing dialog box, click Add Spacer. A red X appears, marking the spacer location.

15:  In the Custom Breaks/Spacing dialog box, click Insert Next I/O Point.

16:  Click Insert Next I/O Point again.

17:  Click Add Spacer.

18:  Click Insert Next I/O Point.

19:  Click Break Module Now.
AutoCAD® Electrical combines the inserted symbols in a single PLC module block and prompts you to select an insertion point for the remainder of the module.

20:  Press ESC.

21:  In the Data Saved dialog box, click OK.

22:  Insert a Ladder and the Remainder of the PLC Module:

On the Schematic tab, Insert Wires/Wire Numbers panel, Ladders flyout, click Insert Ladder.

23:  In the Insert Ladder dialog box, do the following:
â–  For Width, type 10.0
â–  For Spacing, type 0.75
â–  For Rungs, type 26
â–  Click OK.

24:  Select the insertion point at approximately 16,21

25:  On the Schematic tab, Insert Components panel, click Insert PLCs > Insert PLC (Parametric).

26:  In the Continue "Broken" Module dialog box, click Continue Module.

27:  Select the insertion point for the broken module on rung 522 near the right side.

28:  In the Module Layout dialog box, click Insert All. Click OK.

29:  In the I/O Addressing dialog box, click Decimal.
AutoCAD Electrical assembles and combines the remainder of the PLC module into a single block as a child component of the initially inserted parent.

 

Prerequisites

Completion of the PLC I/O Address-Based Tagging Lesson

Objective:  In this project, you add wire numbers to your drawings, automatically assigning wire numbers that match the attached PLC I/O address.

Instructions

1:  If the Project Manager is not displayed, on the Project tab, Project Tools panel, click Manager.

2:  If PLC_Modules_NFPA is the active project, skip to step 6. If it is open but not active, in the Project Manager, right-click PLC_Modules_NFPA. Click Activate. Skip to step 6.

3:  In the Project Manager, click Open Project.

4:  Browse to where you installed the exercise files and select PLC_Modules_NFPA.wdp. Click Open.

5:  From the Projects list, click the expansion node next to PLC_Modules_NFPA to expand the drawing list.

6:  Right-click PLC_Modules_NFPA_06.dwg. Click Open.

7:  Zoom in to rungs 602-608. Notice the existing referenced-based component tags and wire numbers. You change these to PLC address-based tags.

8:  On the Schematic tab, Other Tools panel, click Drawing Properties.

9:  In the Drawing Properties dialog box, Components tab, select the Search for PLC I/O Address on Insert check box.

10:  On the Wire Numbers tab, select the Search for PLC I/O Address on Insert check box. Click OK.

11:  On the Schematic tab, Edit Components panel, click Retag Components.

12:  In the Retag Components dialog box, click Active Drawing (All). Click OK.

13:  If prompted, in the Create Zip Back-up? dialog box, click No Backup.

14:  In the Update Other Drawings? dialog box, click Task to store the update operation in the Project Task list (which is run at a later time from the Project Manager).

15:  On the Schematic tab, Insert Wires/Wire Numbers panel, click Wire Numbers.

16:  In the Wire Tagging dialog box, click Drawing-wide.

 
Component tags and wire numbers are updated to the PLC I/O address-based tag format.
