[MAX8_R] Maximum of 8 real values

Function block MAX8_R calculates the maximum value of up to 8 valid, real values.

MAX8_R calculates the maximum value of up to 8 valid, real values.

Functioning

MAX8_R calculates the maximum value for inputs [In1]...[In8] and issues it at output [Out]. Only unlocked input values are considered. Inputs are unlocked if [EnIn1]...[EnIn8] = 1.

The input that presently determines the output value is available in [PrInNo] = 1..8.

Unused inputs [In1]...[In8] are disabled by setting the corresponding parameter [EnIn1]...[EnIn8] = 0.

If all inputs are locked EnIn1]...[EnIn8] = 0, [DefVal] is issued.

0: All inputs are locked [EnIn1]...[EnIn8] = No; [Out] = [DefVal].
1...8: Number of input whose value is issued on output [Out].

Troubleshooting

If all inputs are locked EnIn1]...[EnIn8] = 0, [DefVal] is issued and [PrInNr] = 0 is set.
