GT(_E), GE(_E), EQ(_E), LE(_E), LT(_E)
These functions output the data comparison result of input values.
*1 The input variable "s" can be changed in the range of 2 to 28.

■Operation processing
• These functions perform a comparison operation of input values of (s) and output operation results from (d) in the BOOL
type.
• A data value of the INT, DINT, REAL, BOOL, WORD, DWORD, TIME, or STRING type can be input to (s).
