On the second lower rung, if the box already EQuals 150 units, then it cannot contain even another small bottle (150 + 10 = 160). If the box only has 145 and the next is a small broken bottle, no problem, it will fit in exactly, so do not move the box and it will fill to 100%. Welcome to the PLCS net File Manager The Silo Lab Exercise 3 pdf Just started learning ladder logic and this is my attempt BLS PLC WIZZAAHD rsl LOGIXPRO BOTTLE LINE SIM. The reason is that the encoder should be used to determine the timing for most functions.

Only 3 or 4 timers should be used for entire project, including Exercise 6. If so, the box must be moved because the incoming large broken (= 15 units) will overfill (145 + 15 = 160). RichB, Here are some more tips for the Bottle Line Simulator: 1. Elme Online 605 subscribers Subscribe 3.4K views 2 years ago LogixPro Student Exercises Here we look at how to determine where the bit you want in the table is located. The other B3:7/x bits on the rung determine if the next broken bottle is large AND if the box already contains '145' units or more of glass. The attached picture shows a way to compute the broken glass, then use only 2 comparisons to always fill the scrap box to 93.5% or 100% full. You must multiply your Small and Large multipliers (1 and 1.5) by 10 to come up with an integer value for the broken glass. Because your LogixPro (and the Allen Bradley SLC 5/02 that it simulates) does not have Floating-Point decimal numbers, you cannot divide by 0.6666 and you cannot multiply by 1.5. You cannot just add them together because the small is only 2/3 the quantity of the large (or Large = 1.5 times the Small).

So first you create a value ('BROKEN GLASS' in N7:2) that is composed of both the Small and Large Broken bottles. As in many programming applications, the key is to recognize that you need a simple way to compare the total of 2 unequal items. 510 subscribers Subscribe 4.4K views 1 year ago LogixPro Student Exercises In this exercise we fill and cap the bottles on the Logix Pro bottle line simulation. For your 'Botle Boxing' program, your Rung 009 with 11 rung branches and 22 comparisons is way too complicated, but still it does not maximize the amount of broken glass going into each scrap box.
