7.3.8.20 NSW (numeric change-over switch)
Brief description
This function block switches one of two numeric input variables (REAL type) to the output.
Mode of operation
If input I = 0, X0 is switched to output Y.
If input I = 1, X1 is switched to output Y.
7.3.8.21 LIM (limiter)
Brief description
● Function block for limiting
● Adjustable upper and lower limit
● Indication when set limits are reached
Mode of operation
This function block transfers input variable X to its output Y. The input variable is limited
depending on LU and LL.
If the input variable reaches the upper limit LU, output QU is set to 1.
If the input variable reaches the lower limit LL, output QL is set to 1.
If the lower limit is greater than or equal to the upper limit, output Y is set to the upper limit
LU.
