LED (and Display) Control
series4x (Display) supports three modes for controlling its LEDs (and Display):
- Automatic Scene Selection
- Scene controlled by IO-Link-Process Data
- Advanced Control by IO-Link Process Data
The control mode can be selected via IO-Link parameter LED Control Mode (see ISDU Indices).
Automatic Scene Selection
The LEDs (and Display) behave like the selected Scene. Scene n is selected by the state of Touch (Sensor actuation) and the state of the input pins E1 and E2:
| LED Scene | Actuation Flag | E1 | E2 | None | Pin2 (E1) | Pin2 (E1) and Pin5 (E2) |
|---|---|---|---|---|---|---|
| 0 | 0 | 0 | 0 | ✓ | ✓ | ✓ |
| 1 | 1 | 0 | 0 | ✓ | ✓ | ✓ |
| 2 | 0 | 1 | 0 | ✓ | ✓ | |
| 3 | 1 | 1 | 0 | ✓ | ✓ | |
| 4 | 0 | 0 | 1 | ✓ | ||
| 5 | 1 | 0 | 1 | ✓ | ||
| 6 | 0 | 1 | 1 | ✓ | ||
| 7 | 1 | 1 | 1 | ✓ |
The number of applicable scenes depends on parameter Active Inputs:
| Active Inputs | Applicable Scenes |
|---|---|
| None (3 pin mode) | 0, 1 |
| Pin2 (E1) (4 pin mode) | 0 ... 3 |
| Pin2 (E1) and Pin5 (E2) (5 pin mode) | 0 ... 7 |
Scene Controlled by IO-Link Process Data
The active Scene is set to the value written to the LED Scene field of the Process Data. For LED Scene = 255, the active Scene is selected by inputs like "Automatic Scene Selection" (LED Control Mode = 0).
LEDs always act like described in the active Scene. The Display behavior depends on the Display Mode field of Process Data: It can show the Display Text of the selected Scene, or a number or a text given in the respective field of Process Data.
Advanced Control by IO-Link Process Data
The LED pattern, color, brightness, effect, and effect frequency is controlled by IO-Link process data. For more information see Process Data.
The LED indexing is clockwise starting from the top left LED (LED 1).
Output Locking
The "Output Locking" was designed for applications without IO-Link only. The sensor needs to be set to LED Control Mode "Automatic Scene selection". It locks the Pin 4 output signal but has no impact on the Actuation Flag.
The "Output Locking" has no influence on the scene or scene change. This means touching/inputs on E1/E2 will change the scene accordingly.
For locking, the inputs must be set active (Active Inputs parameter).
Output locking can be used to interrupt an infinite timer / terminate an output signal.
