00:00Today I present the work related to instrumentation, which deals with the following exercises
00:05Part 1. Two-way traffic light, where the activation of the sequence is visualized by means of LED indicators.
00:12IO factor.
00:13And part 2. Create a program to control the start of an AK motor using two different methods.
00:20Part 3. Perform two six-lamp lighting sequences in IO factor.
00:26For this purpose, it will have two pushbuttons, where if P1 is activated sequence 1 will be executed, if P2 is
00:33Once activated, sequence 2 will be executed.
00:36If P1 and P2 are activated simultaneously, the lamps will turn on until this condition is removed.
00:45In the description of the variable table, we declare the respective inputs and outputs for the respective programming.
00:53The programming is as follows: I start with a normally open contact, first 0, 1, which will be 1, followed by
01:01a timer called red time 1 with a time count of 5S, 2.
01:06Before the timer I set an output Q0, 0 with the name red 1.
01:11When I start with contact NAI 0, 1, the timer gives me a count of 5S and the
01:16output and will also be blocked with an NC contact on the ROV timer.
01:26The rest of the programming is described in detail in the written work.
01:38Once the programming is done, I move on to the simulation.
01:49Here we can see the connection of the PLC S71200 with Factor I.
02:03Okay, this is the 2B traffic light sequence.
02:30Now I'm going to simulate the lamp lighting sequences in Factor I.
02:37In the description of the variable table, we declare the respective inputs and outputs.
02:50Now I will describe part of the programming.
02:53I start with an NC contact first 0, 0 which will be 1, then an NC contact Q0, 2, and a
03:00NC contact Q0, 1, of a timer called time with a 5S time count.
03:06Before the timer I set an output Q0, 0 with the name time.
03:10When I start with the NC contact first, 0, 0, the timer gives me a count of 5S and activates
03:17The output will also be blocked with NC contacts on the timer.
03:25Similarly, the same sequence is established as in the previous exercise.
03:45Now I'm going to simulate the lighting of lamps and their two sequences.
04:13Here we can see how the Enceptor sequences work.
04:46The final exercise deals with reversal of direction.
04:57The following applies to the reversing mechanism of a motor.
05:00A cable is run from the line and connected to an NC push button, which will be used as
05:05The stop button for this circuit is used as a protective element in the control circuit.
05:11minus one of them to avoid problems when there is a failure.
05:15Observe the phase and neutral lines in the connection to be made to PLC-S7-1200.
05:26In the control programming, it was done like this: one.
05:29I define the negative and positive lines.
05:322. I establish the normally open and closed contacts and at the output goes M0-0.
05:383. Contact M0-0 is connected, then in a closed contact to contact KM1, and the motor will rotate
05:47in one sense in the power diagram of the normally open contactors of the motor power diagram.
05:534. Contact M0-0 is connected to a time on the line which, once 5 seconds have elapsed, will activate
05:59to contact U5.
06:01The U contact will activate the second time on the line which will establish the KM2 contact.
06:06And the motor will rotate in the other direction.
06:10Now I'm going to simulate the braking of a three-phase motor with an on-line timer.
06:144. The process was developed according to exercise 2 proposed for both KM1.
06:26PLC logo has inputs and outputs; the input would be from I1 to I8, the output would be from Q1, Q4.
06:332. The logo power supply is wired to P1, P2, and a NAR push button is connected to input I1 from
06:40the phase and neutral lines together at input I4 with an NAR push button.
06:443. The NAR button which will be the stop or stop button.
06:47At the output it would be Q1, Q2 with phase and neutral lines to a ruin called KM4.
06:53In the power circuit, we activate the circuit breakers together with the contactors named KM for activation
07:00of the 5th engine.
07:01In the control stage, its programming is with LAR 6.
07:05The control stage begins with a NAR contact, called STAR, followed by another NAR contact,
07:12Stop at the exit of M1 which corresponds to engine 7.
07:15The interlock is M1 on an NAR 8 contact.
07:19M1 in a NAR contact to KM output that corresponds to both the contactors and the spool in the PLC.
07:27Well, that's all, thank you for your time.
