Configure I/O

The Configure I/O dialog has two main functions: register or synchronize the controller with the list of modules and to configure the modules.

This dialog is always invoked from a parent dialog. The controller is determined by the parent dialog. For example, the Setup Wizard asks you to select a controller before this dialog is displayed.

Registering (Synchronizing)

The dialog displays a list of modules currently connected to the controller. Use the “Rescan” button to refresh the list. For example, if you add another module to the network, you should “rescan” so that its name appears in the list. In some cases, a module may be busy and not aswer the scan. In this case, you may use “rescan” to refresh the list.

Click the “Synchronize” button to register the modules in the list with the controller. This saves information about the modules on the controller. Afterwards, the controller expects to see the registered modules in its network. Only the input and outputs of the registered modules may be logged, or used in automated tasks.

Configuring the Modules

Once modules are registered, they may be configured. First, select a module from the list. Click on the modules name to select it. Module configuration depends on the specific module. In general, you select the inputs and outputs that are used. In some cases, further information may be needed. For example, you may specify the units of a temperature input (as Fahrenheit or Celsius). Each input and output has a name. Naming the variables is a key concept (see “Named Variables” in the section “Concepts”). Controllers access the inputs and outputs by their assigned names when logging data or performing automated tasks. Module inputs and outputs have default names. However, if you use more than one module, you should rename the variables so that the names are unique.

Reset Module

The selected module may be reset. Click on the modules name to select it. There are two reset options. The module may be reset, as if the power were cycled, or the module may be reverted back to its original settings. This typically disables all inputs and outputs, and reverts the variable manes to their defaults.
