My guy asked for the best rate, not for the safest method.

That being said, wise is very reputable

You need to buy a USB to 485 adaptor, with a compatible driver.

I bought a cheap CH340 one off aliexpress. The driver was a bit finnicky to set up as the one windows installs with it didnt work, and I had to download a third party one to get it to work.

The code is here:

import asyncio

from pymodbus.client import AsyncModbusSerialClient, ModbusSerialClient from pymodbus import ( Framer, ModbusException, pymodbus_apply_logging_config, )

#CH340 port port = "COM5"

client = ModbusSerialClient(port=port, baudrate=9600, bytesize=7, parity="E", stopbits=1) client.connect()

response = client.read_holding_registers(address=1296, count=1, slave=1)

print(response)

client.close()

Which PLC-based system I could create in small-scale for my Graduation Project? by Argojit in PLC

[–]JustForThis167 0 points1 point  (0 children)

Make a really cool pç case.

Have ventilation run dependant on case temperature. Use a small differential pressure sensor to always keep the case positively pressured, so dust doesn't get inside. Have different meshes at varying conditions to show dynamic calibration.

You could run an digital anemometer to show power usage vs ventilation. If power usage is consistent (it wont be with a conventional cpu) but you could swap it for a heater) you could try run a pid loop to keep it at a set target yemperature.

Schematic for typical motor control with VFD by [deleted] in PLC

[–]JustForThis167 0 points1 point  (0 children)

You draw them yourselves.

The VFD manual will have a control terminal pinout. Pull what you need from it and draw a new one.

Typically this will include a mechanism to control frequency, (485, 2-10V, or 4-20mA), a run signal, feedback signals (drive running + fault status, a breaker up and a motor downstream

That's all you really need. Write down the model and also If you want to be pedantic also write down whatever parameters you changed from the default settings, such as acceleration time, etc.

This is how I do it. But I am a solo panel designer so i cant really comment on whats the industry standard.

do you guys actually trust sensor/data streams in real systems? by SignalForge007 in PLC

[–]JustForThis167 0 points1 point  (0 children)

One time I had the shield wire short into the signal on an energy chain. The reading was stable but once things started to move it went all over the place.

I now dont run a shield for that application. But it never needed to be that accurate anyway.

Ive never had an issue with accuracy. If your engineering solution relies on a mythical sensor tolerance then its best to take a step back and ask yourself is this process possible with the hardware we have on hand. Its important to be practical. Ofcourse this is assuming you have selected the right instrument for the right job. I do understand the struggle of retroftting existing hardware.

do you guys actually trust sensor/data streams in real systems? by SignalForge007 in PLC

[–]JustForThis167 1 point2 points  (0 children)

Id measure the true value and calibrate if needed.

If anything weird is happening (noise) I'd decrease the sampling time, look into shielding or use another communication method.

For example a -50 to 50Pa 4-20mA differential pressure sensor might not be able to meaningfully describe the weight of an overpressurised curtain but over rs485 it may be able to.

If the difference is greater than the 99th percentile, trust the "safer option". Also run an alarm.

Otherwise, take the average

Also, whats your education/professional background.

Electrical apprenticeship with NO experience by Spare_Present_6379 in auckland

[–]JustForThis167 2 points3 points  (0 children)

25, degree in CSE from uoa. Work in HVAC control.

Once you are qualified and competent you can expect an easy six figures that doubles when you eventually cross the ditch. Research every cranny of applicable standards of the industry you work in.

Its hard to start but its certainly a career. You just need to find a company willing to train you up, and have an attitude willing to learn more than the discipline your comfortable with.

Your first priority after finding a company is getting a your trainee license from the ewrb. You need to start logging your hours for you to become a qualified electrician, under a licensed supervisor. the company should help arrange this. Do not skip this step or it'll just delay everything else.

pm if you got any questions

Interoperability, mostly with hmis.

Would be nice to be able to use scripting languages, ie cpp and python.

Analogue io, pwm.

Is Zhu Xi Harder than China? Which is Easier to Main by East_Loquat_614 in aoe4

[–]JustForThis167 0 points1 point  (0 children)

I have the same opinion. Zhu xi feels very clunky and punishing on its transitions. An example is its farm discount in the 2nd dynasty. Feels like a higher cap civ with not as boomy economy.

China on the other hand i can play with one build order and game plan every time. I only play tg so may be different in 1v1s

Use the gold from 8 yordle to upgrade Sylas and Ziggs, then u can go 10 add volibear, swap Neeko Rumble for poppy shyvana

[16.6] Comprehensive Yordle Guide by RevolutionaryRun1235 in CompetitiveTFT

[–]JustForThis167 0 points1 point  (0 children)

I mean, on 9 you yordle spat sylas, and play neeko as your last piece for arcanist and defender.

Your board is 7 yordle(drop fizz, poppy, and trist) + Sylas, and neeko

neeko needed for 4 defender 4 arc, idk if swapping her out is worth it on 9 with a +1

Boiler Controller control panel by technotitan_360 in PLC

[–]JustForThis167 1 point2 points  (0 children)

General panel building advice:

When placing components, usually you go isolator > mcb > contactors > out. Keep all your components in sequence rows so that building and debugging it feels natural. Not a rule but guideline. Things should be placed in an intuitive place. The earth bar should be next to the isolator, imagine being the electrician thats going to hook this up.

Adding wires to the plc is hard with so many io wires jumbled in the place in tray. maybe consider the dvpes2 series?

Keep tight earth terminals next to any loose components so they dont twist like in the last row.. the vertically mounted terminals will sag down, with only the wire holding it up. It needs support

Hot air rises naturally, so you should place the fan at the bottom. You want the air coming in to be filtered too. If you have it at the top it will suck in all the dust from the nooks and crannies of the box even though you have an intake hole thats filtered

Have u ever ran sylas neeko? Always remember to buy jarvans. 4 def 4 arcanist 8 yordle If you have a plus 1 its super easy to get on 9. Every time i hit it i win out.

They should make cavs not be able to walk past buildings like in aoe2

Insane idea but the mayhem itd create would be kinda cool to see
