You use 20 if you have exceeded twice, and so on.īinary numbers are quite the same. In decimal, you use 10 if you have exceeded counting through all representations (0 to 9) once. The Decimal number system-which we are familiar with, has 10 (prefix Deci-) representations: 0, 1, 2, 3, up to 9.īecause you are an intelligent human being, you may have guessed that more digits can represent more values. Quarter(four)nary means four possible outputs. Confused? For a single digit, BI (two)-nary means two possible outputs. What is Binary?īinary is part of the M-ary system of representation when M is the total number of results. Therefore, it is much simpler to use the Binary concept in Number Systems to represent the outputs. The result may also vary by the tiniest amount and it is already considered a different output. The “Maybe” in between the “Yes or No”, or the “Medium” in between “High or Low”. Instead of 0 or 1 only, we have values in between. In analog, we consider an INFINITE number of values. This simplifies input-output relationships as compared to the analog side of things. This means that it’s either “True or False”, “High or Low”, “Yes or No”, “0 or 1”. Logic circuits are digital, so they produce outputs that are discrete in nature. PLC Programming was based on Relay Logic, and Relay Logic was based on-well, the fundamentals of logic. The next step is actually designing a program for your controller to execute the steps required to perform your automated control system.īut first, you have to know some logical fundamentals that will allow your system to create decisions on its own.

I found this helpful video that actually shows a control problem to solve: Lastly, you would want to control an input valve to regulate the flow of water into your tank.

In this case, because there are water levels involved, you must use level sensors: One for the Full level and one for the Near Empty level. What do you do?īecause you have clearly identified what outcomes you want along with the conditions, you now have to think the appropriate types of sensors and output devices that you must use. You want the tank to fill up until it is full and then automatically refill one the water level is near empty just to maintain the pressure. This means that the final outcomes must be determined clearly along with the conditions that determine the outcome.Īlso, the input and output devices must be clearly identified.įor instance, you want a control system for your water tank.

It was based on the time-proven system structure of the AC31 series 90 variant. The Advant Controller AC31-S was available for safety-related applications. AC31 series 90 utilized the 907 AC 1131 programming software, also developed in accordance with IEC61131-3.

Ethernet, PROFIBUS DP, ARCNET or CANopen.īoth AC31 series 40 and 50 utilized the same AC31GRAF software which conformed to the IEC61131-3 standard. The combination of integrated communication fieldbus allowed to connect the PLC to several protocols like e.g. The PLC provided 60 I/Os internally and could be expanded decentrally. The Advant Controller 31 series 90 offered powerful PLCs for challenging applications with various configuration options and up to five communication interfaces. The Advant Controller 31 series 40-50 offered small and compact PLCs with central and decentralized extensions. Sigmatronic, Procontic) are obsolete and were replaced by the AC500 PLC platform.
