Detailed description
Original instructions
Parameter description MX_IND
If X exceeds the value of MX_HIGH, the function block reports this status with MX_IND = 1.
If X falls below the value of MX_LOW, the function block reports this status with MX_IND = 0.
Formulas:
MX_INDi = 1, if X > MX_HIGH
MX_INDi = 0, if X < MX_LOW
otherwise
MX_INDi = MX_IND(i-1)
If MX_LOW is greater than MX_HIGH, no hysterisis is created and the function block reports this state with MX_IND = 1.
Parameter description MN_IND
If X falls below the value of MN_HIGH, the function block reports this status with MN_IND = 1.
If X exceeds the value of MN_LOW, the function block reports this status with MN_IND = 0.
Formulas:
MN_INDi = 1, if X < MN_HIGH
MN_INDi = 0, if X > MN_LOW
otherwise
MN_INDi = MN_IND(i-1)
If MN_HIGH is greater than MN_LOW, no hysterisis is created and the function block reports this state with MN_IND = 1.
