There are 4 types of data value that you can use in your expressions. For more information, see the topics that are listed in the gray footer section at the bottom of this topic. Select the relevant entry to display the topic that you require.
Many functions have arguments that need to be of a certain data type. If you use the wrong data type for an argument, Geo SCADA Expert will try to convert the argument into the correct data type. For example, if you define a REAL value when a BOOL is required, Geo SCADA Expert will try to convert the REAL into a BOOL. In the case of a string argument, the content of the string determines whether the conversion is successful. For example, if the required data type is Integer, but you define a string argument as "1234", the argument will work successfully. This is because Geo SCADA Expert can convert the content of the string into an Integer value successfully (the content of the string matches a valid value for the required data type).
