The return value has the signal state "1" if the time atparameter DT1 is greater (younger) than the time at parameter DT2. The function doesnot report any errors.Parameter Declaration Data type Memory area DescriptionDT1* INPUT DATE_AND_TIME D, L Input variable in format TDDT2* INPUT DATE_AND_TIME D, L Input variable in format TDRET_VAL OUTPUT BOOL I, Q, M, D, L Comparison result*) You can assign only a symbolically defined variable for the parameter.15.2.16 FC 15 - GT_STRNG - Compare STRING for greater thanThe function FC 15 compares the contents of two variables in the data format STRING tofind out if the first is greater than the other and outputs the result of the comparison as areturn value. The return value has the signal state "1" if the string at parameter S1 isgreater than the string at parameter S2. The characters are compared by their ASCIIcode (e.g. 'a' is greater than 'A'), starting from the left. The first character to be differentdecides the result of the comparison. If the left part of the longer string is identical to theshorter string, the longer string is considered as greater. The function does not report anyerrors.Parameter Declaration Data type Memory area DescriptionS1* INPUT STRING D, L Input variable in format STRINGS2* INPUT STRING D, L Input variable in format STRINGRET_VAL OUTPUT BOOL I, Q, M, D, L Comparison result*) You can assign only a symbolically defined variable for the parameter.ParameterDescriptionParameterDescriptionParameterVIPA SPEED7StandardIEC > FC 15 - GT_STRNG - Compare STRING for greater thanHB00 | OPL_SP7 | Operation list | en | 18-30810
