I need help with an ASEM HMI130TF with a SCADA program on it works on Windows 7. it is connected with LAN network TCP/ip with a PLC and another HMI, and it has a static ip.

the problem is it sometimes loses connectivity to this...
ok, while i was i figured another configuration it just simple modification i hope it work, Q1 is IRF5305 p channel mosfet Vgs1 need to be 12 or 0 and this the job of Q2 n channel , Q2 is controlled by the opto with 5 volts on so Q2 won't be completly open but will deliver the required volt to...
i was making a simple buck converter using an AVR as a controller and 6n137 optocoupler as a highspeed isolator
datasheet : https://pdf1.alldatasheet.com/datasheet-pdf/view/30862/TOSHIBA/6N137.html
and in last minute after i bought the chip just discovered that the output voltage is only 5...
My goal is it to control one mosfet with pwm from ATMEGA32A.
after watching some tutorial and codes on internet i got this code
#ifndef F_CPU // if F_CPU was not defined in Project -> Properties
#define F_CPU 1000000UL // define it now as 1 MHz unsigned long
#endif
#include <avr/io.h>...
hey, i am new to the AVR world, just got an ATMEGA32A, and started to watch tutorials on youtube and surfing on avrfreaks.net but most of tutorial doesn't mention any thing about "fuses of avr" but found some single videos is talking about burning the fuses of avr before starting and warning...
Re: need help with choosing inductor for a buck conveter.
@Akanimo I am only designing this to learn I will not use it in a real application so I trying to lower the current for the safety of me and the components.
@FvM, as I said the average for the first 150 microseconds, is about 3 watt but...
need help with choosing inductor for a buck conveter.
I am designing a very simple buck converter but the simulator is showing that the inductance average power is 3 watt in only first 150 microseconds then it goes to to mW the rest of the time, if i used the usual 0.5 watt available...
i know there are many explanations on the internet for the difference between n,p channel mosfets, i read many of them but still can't decide which is best to use in a simple buck converter circuit? will dopping of mosfet will have major difference in the behaviour of voltage and current or it's...
i am a new to power electronics field and trying to design a simple buck converter, i started with simulation before real acting but i noticed something wired in diode current, it reaches 28 amps in first 200us is that usaul? is this just a transint wave that won't affect the circuit? will 4 amp...
