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.
