RReset (a Boolean operand)
Depending on the content of the accumulator, the operand defined in the operand field is reset or kept. TRUE in the accumulator resets the operand, i.e. the operand is set to 0 (FALSE).
Valid operands for this operator must be of one of the following data types:BOOL
Operator only available in IL programming language.
All input and output variables used for programming this function have been declared in the POU header.
var_1 and var_2 can be of any valid data type, var_3 and var_4 have to be of type BOOL.
var_3 is only reset (set to 0 or FALSE) if the accumulator is TRUE, i.e. if var_1=var_2.
