Block
Mask
Description
This block enables the use and configuration of digital switches present on the OP6227 SwitchModule board (Part # 519-0009).
Parameters
| Controller Name | Each functionality block such as the OpFcn DigitalSwitch block must refer to an OpCtrl block such as the OpCtrl SwitchModule block that will manage the data transfer with the IO board. The binding between OpFcn and OpCtrl blocks is performed via the use of the Controller name that each OpCtrl block uniquely defines. In this case, the controller name could be 'SM' in both blocks. This binding is checked during the initialization phase of the model. If no OpCtrl block is found that defines the same Controller Name as this OpFcn DigitalSwitch block, the OpFcn DigitalSwitch block is simply disabled and returns 0s. |

The image below shows an example of a controller name, here 'SM', used with success.
| Selection of Functionalities | This field is used to determine which digital switch the OpFcn DigitalSwitch block is tied to. For the example above, the block refers to the discrete switch 0 and drives the DS0 output pin, it has a 0 typed in this field. There are specific numbers that refer to the discrete, flexible, and rotary switches. All are explained in the table below. |
|---|
| Switch Type | Pin-outs | Assign number |
|---|---|---|
| Discrete | DS0 to DS29 | 0 to 29 |
| Flexible | FSO0 to FSO4 | 0 to 34 |
| Rotary | RSO0 to RSO7 | 35 to 42 |

| Configuration | From the drop-down list, the user defines the configuration (Unconfigured, Active High, Active Low, Open Drain, Open Source) of the switch. Below is an explanation of the different configurations. |
|---|---|
| A. Unconfigured (1 in RT-Lab parameters panel) | Switch is disabled. |
| B. Active High (2 in RT-Lab parameters panel) | When off, the switch will sink the signal to the ground; when on, the switch will source to Rail. |
| C. Active Low (3 in RT-Lab parameters panel) | When off, the switch will source signal to Rail; when on, the switch will sink to the ground. |
| D. Open Drain (4 in RT-Lab parameters panel) | When off, the switch will be open state; when on, the switch will sink signal to ground. |
| E. Open Source (5 in RT-Lab parameters panel) | When off, the switch will be open state; when on, the switch will source signal to Rail. |
Inputs
State: This signal gives the information to the switch if it should be ON or OFF.
Outputs
State: This signal gives the information from the switch if it is set ON or OFF.
Characteristics and Limitations
Connector Pin Assignments
The user should refer to the documentation of the IO board or he should see the OpCtrl SwitchModule help page.
Note: Characteristics and limitations of the SM can be found on the OpCtrl SwitchModule help page.
