Selection of I/O functions
The signal interfaces of the EP8601-0022 are multifunctional. You can select the I/O functions of the signal interfaces in TwinCAT.
The I/O functions are selected by assigning so-called ModuleGroups to SlotGroups. A SlotGroup comprises one or more signal interfaces. A ModuleGroup is a predefined set of I/O functions for these signal interfaces.
Further information on modules and slots can be found in chapter Basics of the "Modules/Slots" procedure.
The following example shows how to assign a ModuleGroup to a SlotGroup in TwinCAT.
Example
Notice | |
Links with PLC variables are removed If you assign another ModuleGroup to a SlotGroup, all links between the inputs and outputs of this SlotGroup and PLC variables are removed. |
- Prerequisite: TwinCAT 3.1, Build 4024.50 or higher.
- 1. Start TwinCAT in Config Mode.
- 2. Click on the "Slots" tab.
- 3. Select a SlotGroup, e.g. SlotGroup 4
- 4. Select a ModuleGroup that you want to assign to the SlotGroup.
- 5. Assign the ModuleGroup.
- 6. Assign the ModuleGroup "EMPTYn" to all unused ModuleGroups.
SlotGroups without an assigned ModuleGroup lead to an error message when activating the configuration, see chapter Diag Messages.
- 7. Click on "Reload Devices".
- From TwinCAT 3.1 with Build 4024.59, you can check the resulting connection in the "Product View" tab.
(if you are working offline, you must save the project to update this view)
The state of the status LEDs is also displayed live in this view.
In chapter SlotGroup directory you will find an overview of the SlotGroups and ModuleGroups with cross-references to the corresponding chapters for the connection and configuration of the selected I/O functions.
