Using PLC I/O Modules (4:43 min)
Prerequisites
Completion of the Using PLC I/O Modules Lesson
Objective: Â 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: Â Insert and Break the Parametric PLC Module
Instructions
1: Â If the Project Manager is not displayed, on the Project tab, Project Tools panel, click Manager.
2: Â 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: Â In the Project Manager, click Open Project.
4: Â Browse to where you installed the exercise files. Select PLC_Modules_NFPA.wdp. Click Open.
5: Â From the Projects list, click the expansion node next to PLC_Modules_NFPA to expand the drawing list.
6: Â Right-click PLC_Modules_NFPA_05.dwg. Click Open.
7: Â Zoom into rungs 514-519.
8: Â On the Schematic tab, Insert Components panel, Insert PLC (Parametric) flyout > click Insert PLC (Parametric).
9: Â 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: Â Select the insertion point for the module on rung 513, below the existing PLC module.
11: Â In the Module Layout dialog box, click Allow Spacers/Breaks. Click OK.
12: Â In the I/O Point dialog box, do the following:
â– For Rack, type 1
â– For Slot, type 2
â– Click OK.
13: Â 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: Â In the Custom Breaks/Spacing dialog box, click Add Spacer. A red X appears, marking the spacer location.
15: Â In the Custom Breaks/Spacing dialog box, click Insert Next I/O Point.
16: Â Click Insert Next I/O Point again.
17: Â Click Add Spacer.
18: Â Click Insert Next I/O Point.
19: Â 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: Â Press ESC.
21: Â In the Data Saved dialog box, click OK.
22: Â 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: Â 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: Â Select the insertion point at approximately 16,21
25: Â On the Schematic tab, Insert Components panel, click Insert PLCs > Insert PLC (Parametric).
26: Â In the Continue "Broken" Module dialog box, click Continue Module.
27: Â Select the insertion point for the broken module on rung 522 near the right side.
28: Â In the Module Layout dialog box, click Insert All. Click OK.
29: Â 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.

5: Â From the Projects list, click the expansion node next to PLC_Modules_NFPA to expand the drawing list.
6: Â Right-click PLC_Modules_NFPA_06.dwg. Click Open.
7: Â 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: Â On the Schematic tab, Other Tools panel, click Drawing Properties.
9: Â In the Drawing Properties dialog box, Components tab, select the Search for PLC I/O Address on Insert check box.
10: Â On the Wire Numbers tab, select the Search for PLC I/O Address on Insert check box. Click OK.
11: Â On the Schematic tab, Edit Components panel, click Retag Components.
12: Â In the Retag Components dialog box, click Active Drawing (All). Click OK.
13: Â If prompted, in the Create Zip Back-up? dialog box, click No Backup.
14: Â 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: Â On the Schematic tab, Insert Wires/Wire Numbers panel, click Wire Numbers.
16: Â In the Wire Tagging dialog box, click Drawing-wide.
Â
Component tags and wire numbers are updated to the PLC I/O address-based tag format.
