Should the value be greater than the lower limit and less than the higher limit, the instruction will set the output to TRUE. However, if the opposite is the case, the instruction will evaluate to FALSE. Furthermore, the reversal of the two limits will have the opposite logic effect on the instruction effectively resulting in a NOT of the original instruction. The LIM instruction is very commonly used in ladder logic programming. It stemmed from the parallel use of the GRT and LES Instructions. It gives the user a simple way to make sure that the specified value falls between two distinct limits and is often used for setpoints, temperature readings, etc. As briefly mentioned above, the instruction may be inverted by specifying a Low Limit which is higher than the High Limit. This may seem confusing at first, but is the right approach in certain situations. That being said, avoid this practice as much as possible.
