-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]].

-During the configuration,​ the PLC will be switched to "​Commissioning mode", which means it will stop running the previously deployed solution. After the configuration,​ the PLC will return to its previous state. Make sure, that the connected technology is prepared for this blackout. +

-===== Voltage and Current ​input ===== +===== Reading the input values ​===== 
-Reading the input values for both Voltage and Curent ​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.
