Add I/O Modules

An I/O Module component is defined in the I/O Module Catalogue. This can be for any control system (DCS, SIS, PLC etc.).

Although I/O modules can be added to almost any equipment item, it is more usual to group modules together on rails. In Electrical Wiring Manager DIN Rails offer a convenient method of grouping devices and/or terminal strips together in a user defined sequence.

To add an I/O Module:

• In Equipment Layout window, right-click on any DIN Rail or existing component and click Add I/O Module from the pop-up menu.

• Or, in the Equipment View context-sensitive right-click menu (after right-clicking on an appropriate equipment node), click Add I/O Module menu option.

I/O Modules can also be added from the Cable Block Diagrams window by right-clicking on any Equipment and selecting the Edit Detail option to display the Equipment Layout window.

The I/O Module Definition window is then displayed:

To create a new I/O Module:

1. Enter an I/O Module Tag No or Description.

2. Select an I/O Module definition from the Wiring Manager I/O Module catalogue, by clicking the Select from Catalogue button. Refer to Select an I/O Module from the Catalogue.

3. Optionally select a Status (new, existing etc.) from the Status list.

4. Enter a First Point/Channel No. This defines how Electrical Wiring Manager numbers the points/channels for I/O assignment reports.

5. Enter or select the number of leading zeros for channel numbers in the Leading Zeros field. For example, if you specify 2, channels will be numbered with 2 leading zeros,: 001, 002.

6. Optionally enter a Start Address. This will define how Electrical Wiring Manager creates each point/channel Address (only if a value is entered: for example, %AI00201).

7. The Properties tab is optionally used to enter data for I/O module properties such as Rack/Slot, System etc. that can be viewed in the I/O Allocation Gridview/Report and added to drawings produced with Electrical Designer.

8. Once an I/O Module is selected, the Catalogue Information fields display the I/O Type, Model No, Manufacturer, Description, No of Points etc. and the graphic is updated to show the terminal arrangement of the selected device as described below.

   

   Note:
   I/O Catalogue information is fixed for each specific catalogue entry. Users cannot edit I/O Module information from project equipment. Users can only edit /add modules from the Wiring Manager I/O Module Catalogue. Also, if a catalogue definition is changed in the I/O Module catalogue all the project instances are changed to the new definition.

9. Click Save to save the new device to the parent equipment (or DIN Rail).

An I/O Module can be edited by selecting a different I/O Module from the catalogue at any time.
