Testing Individual Modules:

  1. Open the Device Detail view.
  2. Click a module.
  3. Click the [Create] button in the “IO-CHECK” tab of the menu ribbon
  4. A tab is opened in the workspace, in which the selected module is displayed.
  5. Display of an I/O Module for the Input/Output Test
  6. To add additional modules to this test, repeat steps 1–3.

Testing an Entire Node:

  1. Open the Network view.
  2. Click a device.
  3. Click the [Compile] button in the “IO-CHECK” tab of the menu ribbon.
  4. Display of a Node for the Input/Output Test
  5. An overview of input/output channels of the corresponding modules is displayed in both cases.
  6. Click the [Connect] button in the menu ribbon.
  7. The monitoring function is active first. The current values are displayed. If required, the “Result” column can be switched on/off via the button of the same name in the menu ribbon.

  12. Besides value monitoring, you can also write or read them.
  13. Switch to manual override mode by clicking [Manual override mode] in the menu ribbon.
  14. Change the individual values. For this use, the slide adjuster and entry fields for analog output terminals; for digital output terminals click, the LED symbol.
  15. Changing Analog and Digital Values
  16. Changed values are indicated with an asterisk (*) and the number of prepared changes shown as a number in the menu ribbon (here: 3) if “Collect” is active (blue background).
  17. To load all changed values to the I/O module click the [Write now] button in the menu ribbon. The write operation is performed once.
