The guideline is right if the try out worth is among the high and low values. The programmer needs to supply 3 items of information to the LIM guideline whilst programming. the 1st is a low restrict, that are a relentless or an handle that comprises the specified worth. The deal with will comprise an integer or floating-point price. the second one is a attempt price, that's a relentless or the tackle of a cost that's to be demonstrated. If the attempt worth is in the diversity special, the rung could be actual. The 3rd worth is the excessive restrict, which might be a relentless or the handle of a price. determine 7-18 exhibits using a LIM guide. If the worth in Cycle_Timer. ACC is larger than or equivalent to the Low restrict price (0) and no more than or equivalent to the excessive restrict worth (10000), the rung may be actual and the output Fan_Motor might be energized. be aware that tags might have been used for the Low restrict and excessive restrict parameters. bankruptcy 7—MATH directions determine 7-18 161 Use of a LIM guideline in RSLogix 5000. now not equivalent To (NEQ) guideline The NEQ guideline is used to check values for inequality. The values verified will be constants or addresses that comprise values. An instance is proven in determine 7-19. If resource A (Var_1) isn't really equivalent to resource B (5), the guideline is correct and the output Fan_Motor (
