Look at the interrupts some are cyclic..as for the resolution and accuracy, that would depend on the plc Exactly why you would not use a timer..I dont know Im sure there are other ways of doing it..but thats the first thought that comes to mind....but you will be lookibg at some sort of...

Same package...it has a lots of different protocols...

Ok...sounds like you've used the most obvious resources. Lenze doesnt sound very helpful... Maybe someone can point out a link...sorry I cant help

Wire shark...whenever I need to sniff a network thats what I use never let me down yet...has loads of different protocals.. So you become familiar with one package as apposed to using several different packages... Loads of tutorials on how to use it...and its free

Hi... Ive used this drive moons ago ....also done a course at Lenze. The couse was less than a day it was basically PLC code... Have you tried youtube??..I done a quick search seems to be a lot there. Its been a while since a layed hands on the drive but it was really a matter of hours to get...

There is some info on youtube...let me see Tunning a control loop - the knowledge board. By ABB...the guy is very good. . Used to know it...but its a case of use it or loose it. If I remember correctly you need to know what form the PID is. ..but there is a way to convert..from one form to...

Just of the cuff..you know how many cycles it takes for one revolution...so you can work backwards to calculate ... solve for p...you have encoder you know what one rev is...you have control of the frequency... https://www.engineeringtoolbox.com/synchronous-motor-frequency-speed-d_649.html...

Looks like a third harmonic in the signal...should measure at the star point...to test point... Star point is floating ground...and most likely not a balanced star point. I assume the caps are filtering your pwm ...so you can get sin like wave form For a load rather connect some incandescent...

y = mx + c

Try Rust...I'm having a look at it now. I needed something that is safer than c and c++ Also I dont want to spend years learning a new language.. Things are upfront in the language ...so it needs a certain mindset... but a very doable exercise

It would be data that is deemed safety critical data..who knows what the satellite is doing with your info Usually client request ..because of some past incident Or as is very typical for the offshore industry...its somebody with a very big ego flying the I am in charge flag ... exactly how do...

Hopefully the correct type of cable is being used...

try a lower rate 9600 and connect one drive ....terminated...correct type of cable. That's where I would start, get one going first. In the end, it's going to be something simple...you just have to find it,,, unfortunately, you are dealing with kit that has nuances in how you interpret the...

Thanks for the reply ,,, Sounds like you have a good idea of the direction you are going to take. There are plenty of videos on youtube that will give you some guidance on how to manage plc memory. Keep at it ...it will click. The Mitsubishi was the first PLC I ever used...you had to program it...

Yea I know does it rhyme with wemens
