You’ll need to configure analog IO in order to get data into your dashboards.
Setting input modes
By default, all analog IO are configured as current. To make changes, find the IG under Settings > Gateways > click the three dots and select Inputs.
Below the image of the IG are the analog and digital IO. To change them, click on the input and select the desired mode.
The mode needed is based on the sensor or output device. If an analog sensor sends a 0-10V signal to the IG, voltage is the correct mode. If the signal is 4-20mA then current is the correct mode.
Creating data inputs
Once the input channel is configured, you need to make data inputs for use in the dashboard. Navigate to Settings > Data Inputs > +Configure New Data Input
Name: This is an arbitrary name used elsewhere when adding this input to dashboard components
The next section allows you too customize the scale of the input to match your application. With a current source, the input scale is fixed at 4-20mA (listed as microamps on screen).
The output scale is entirely changeable and determines the dashboard value based on current input. Your analog sensor will most likely specify what its output range is and should match these fields. For example, if your 4-20mA pressure transducer read 0-100PSI, you would enter 0 for output min and 100 for output max.
A voltage source is slightly different in that the input range is also customizable. While many devices will output a 0-10V signal, 0-5V or others are also compatible with the IG21.
Alternatively, formula may be selected and is useful for pulling raw data or performing mathematical calculations as the data streams in. An example might be scaling values or creating an offset. Use 'x' for the raw data being measured. Notice the field populates automatically when switching over to this mode.
