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]].

| Reading the input values for all modes is the same. Once you set the correct mode, you can just simple read a real value from the variable. The variable is called AI_X.Y depending on the Group (number X) and the position in the group (number Y). To include this variable into the program, you need to **[[en:sw:01-mervis:autogen-hidden|Set Autogen]]**. After that, you will see the variable in **Variable Browser** and you will be able to read it in the **Debugging** mode. | Reading the input values for all modes is the same.
