Adding I/O Modules

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

Although I/O modules can be added to almost any equipment item, it is more usual to group modules together on rails. In 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

• Do one of the following:

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

  • 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 Global tab window.

  The I/O Module Definition window opens.

  

To create a new I/O Module:

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

   Select an I/O Module definition from the Wiring Manager I/O Module catalog by clicking the Select from Catalog button. For further information, refer to Selecting an I/O Module from the Catalog.

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

3. Enter a First Point/Channel No.

   This defines how Wiring Manager numbers the points/channels for I/O assignment reports.

4. 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, for example, 001, 002.

5. Optionally enter a Start Address.

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

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

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

   

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

6. 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 catalog at any time.

   Note: Assigning tags to I/O is done from the Terminations window. See Terminations User Interface and Assign Tags to I/O Modules.
