- | The different analog inputs have different modes of operation, see [[en:automation:02-glossary:analog-inputs-hidden|Analog inputs]]. Change between modes in Mervis is done by configuring the UniPi module, therefor the **changes in modes cannot be done in the program** and the program has to be stopped during the configuration. | + | The different analog inputs have different modes of operation, see [[en:automation:02-glossary:analog-inputs-hidden|Analog inputs]].

- | When reading the value of AO_X.Y in Voltage mode, the value is in volts (value 1.234 = 1.234V). When reading the value in Current mode, the value is in miliampers (value 3.145 = 3.145mA). When reading the value in Resistance mode, tha value is in ohms (value 1012 = 1012Ω) | + | When reading the value of AO_X.Y in Voltage mode, the value is in volts (value 1.234 = 1.234 V⎓).
