When the user chooses to create a new program using the File | New command
or when, during program editing, the user wishes to modify the controller capable of receiving this program using the "Options | Choose the type of controller..." command
The controller category is selected in the first window.
The controllers are grouped into categories based on the number of inputs/outputs, the presence or absence of a display unit and the possibility of adding eXTensions. Finally, category >> groups all the controllers which do not belong to the above categories.
The controller is selected in the second window.
If the user selects an XT type controller, extensions can be added by pressing the "XL", "XC", "XD1", "XD2" or "XD0:XT20" buttons in the following dialogue box:
The Change button is used to modify the controller selected and the related selections.
Important note:
If the user already has a program in the edit window and accesses this function using the Option/Choose the type of controller command, if the inputs of the new controller and its extensions are compatible in terms of number and type with those of the original controller/extensions combination, the IN and OUT function blocks will remain in position on the initial input/output units. However, if the number and type of the inputs/outputs of the original controller are not compatible with those of the controller which has just been selected using the Change button, the inputs/outputs which were on the units which do not exist in the new configuration are moved on the programming area and are therefore disconnected from the inputs and outputs of the controller or the extensions. The programmer must simply select the new slot for these function blocks.
Pressing the "XL", "XC", "XD1", "XD2" and "XD0:XT20" buttons accesses a
list of extensions:
Note:
To access XD0, XD1 and XD2 type extensions, start by selecting an XL REMOTE type extension, press one of the buttons which appears in the Choice of an extension window and then select each remote extension from those which appear. For example, to set up an M2-M2 link, first select an XL_01REMOTE extension then press the XD0-XT20 button which appears. The edit window then appears indicating at the top XL: XL01 LOCAL LINK M2-M2.
Each type of controller has a corresponding background displayed in the Edit window with the I/O specific to the chosen type around the edges. The names of the controller and the extensions are displayed above the wiring sheet.
