Your MIO has eight analog inputs. These inputs can be used as a voltage input. Here you can connect sensors such as proximity or level sensors with analog outputs. The maximum common mode voltage per input may be between 0 and 10 V.
To ensure your configuration works it’s important that your devices are connected to the right input pins.
- You have installed a web browser on your PC (e.g. Chrome or Firefox).
- Your RevPi Core and RevPi MIO are connected via the PiBridge.
- Your RevPi Core is in your network.
- Open your web browser.
- Enter the IP address of your RevPi Core in the address bar of your browser.
- The login window opens.
- Log in with the username “admin”.
- Enter your password. You will find this on the sticker on the side of your RevPi Core.
- Click on “Login”.
- You will now see the current device status of your RevPi Core.
- Click on the “Apps” tab.
- Click on the start button behind the entry “PiCtory” to open PiCtory.
- Select your RevPi Core from the Device Catalog.
- Drag and drop your RevPi Core on to the Configuration Board.
- Open the “I/O Devices” folder in the Device Catalog.
- Select the RevPi MIO.
- Drag and drop the RevPi MIO into the empty slot, to the left of the RevPi Core .
- Define the basic settings for your adapters in the “Device Data” area. This entry is optional. If you use a lot of devices and wish to process the data in another program later, then this entry can be very helpful.
- Configure the outputs in the Value Editor. You will find the detailed setting values and descriptions of how to set the individual operating modes at the end of this chapter.
- Click on “File>Save”. This saves your configuration.
- Click on “Tools>Reset Driver”. This activates the changes for the adapter.
- Do you want to continue using the settings in logiCAD3, Python or C? Then click on “File>Export”.
- A window opens. Here you can specify the format of the file and enter the file name.
Setting and Configuring Operating Mode
You can use the analog inputs in either one of the following operating modes.
Using Analog Input for Voltage Measurement
In the following example we will configure the first analog input to use for voltage measurements. To do this you will need to set the following values in the Value Editor in PiCtory:
AnalogInputMode1 = analog input
→ In the field Analog Input 1 you will see which input voltage is present at the analog input. The value is output in mV.
Using Analog Input for Level Detection
In the following example we will configure the first analog input to use for level detection. To do this you will need to set the following values in the Value Editor in PiCtory:
AnalogInputMode1 = LogicLevelInput
InputLogicLevelVoltage_1= Required switching threshold in millivolts.
→ In the field AnalogInputLogicLevel_1 you will see whether or not the switching threshold has been exceeded.
List of the Setting Values for the Analog Inputs in PiCtory
This is a summary of all the setting values for the analog inputs.
Analog input: Connection is used for voltage measurement.
LogicLevelInput: Connection is used for level detection.
Here you can define whether you wish to use the respective connection for level detection or for voltage measurement.
o: Switching threshold has not been exceeded.
1: Switching threshold has been exceeded.
This value indicates whether the switching threshold has been exceeded.
Analog Input 1-8
Here you will see which input voltage is present at the respective analog input. The value is output in mV.
Here you can define the switching thresholds for the analog inputs.
