  This function block has 6 inputs. For more convenient debugging it is advisable to create some variables that are connected to these inputs. The first is the **channel** input, which is of the string data type. When defining a variable, it is possible to choose a name identical to the name of the input, but it is necessary to choose the same data type, i.e. string. The initial value is the name of the alarm channel, where the default value is the string **alrchannel**:  This function block has 6 inputs.

-Typically, this function can be used to report alarms. Sending an email is triggered by the occurrence of an alarm. Another email will be sent if the alarm went off, was reset and subsequently occurred again. The alarm is active when the value of the variable ''temperature'' exceeds the value of the variable ''temperature_limit'' (with hysteresis).+Typically, this function can be used to report alarms.  Email being sent is triggered by the occurrence of an alarm, in our case variable ''temperature'' exceeds the value of the variable ''temperature_threshold'' (with hysteresis). Another email (with different message content) is sent after the value of ''temperature'' variable is  lowered below the value of ''temperature_threshold'' variable (with hysteresis).
