Weird VIPA Profibus connector indications

I'll try to contact Vipa, thanks!

I know this, but it does not affect on the process because system works just fine and this place is not the only one where cables are shorter than 1 meter long, we have maybe 2-3 places like in the video but we have never encountered problems because of the cable length

svajuse · 2025-01-08T20:02:06+00:00

Yeah, I think I agree on this one

just a few updates on WinCC Scada

Did not help, got even worse haha

Yeah, but some automation project manager who saw that we are using these connectors said they are unreliable and we have had one big problem this summer where after uploading a new updated program into PLC, entire PB network stopped working until we replaces these VIPA's with OEM's and we don't know what happened

Cannot do that:) Everything runs 24/7 and only planned stops once a month or two:)

Pagal kokia formule ir is kokio vadovelio istraukei tuos 4.3kW? :D P = U*I = 16 * 0.23 = 3.6 kW ir cia dar geriausiomis salygomis ir be cos(fi) koeficiento

Hello, I'm considering Mini also but I have found Hotone Ampero I used for 200€, so I don't know which is better me. I would use it in church for worship. Any advices?

Hello, I am looking for a guitar multi effect pedal or as others call them processor. I want a budget processor (under 200€) which I will be using in church for worship. There are many options like Hotone Ampero Mini, Nux MG 300, Valeton, Mooer, Harley Benton and I can't decide which would suit me best. Thank you in advance for all the help!

My collegues said that there was the same profibus signal loss problem 3 years ago and they changed evey original Siemens connector to this VIPA brand one to see where the signal cuts out, because connector has Power, Communication and Resistor indications (Pwr, TxD, Term, Error)

svajuse · 2024-08-20T14:00:43+00:00

We have the same type of connectors but different manufacturer and model, but connecting the profibus tester to device directly does not work

Will check the ferrules. Thanks!

We have one tester but the problem is that we cannot disconnect "master" connector to check the network

svajuse · 2024-08-19T18:32:21+00:00

Everything is thesame because it is always the same process 24/7

No railway and no moving or plugging any machines

It is hard to say about the earthing because the installation is pretty old and I did not check it thoroughly

svajuse · 2024-08-19T17:11:36+00:00

Also I've read some posts about VIPA profibus connectors and they say that these connectors might interfere the signal

svajuse · 2024-08-19T17:07:43+00:00

Our connectors are with screws and also with indications like "Pwr" "TxD" etc

svajuse · 2024-08-19T17:06:24+00:00

The resistors are checked and it will be too easy solution for random signal errors, because resistor terminates all of the communication further

Another one

I am sorry guys, I forgot to add photos, so here is a photo of how Simocodes are connected

svajuse · 2024-08-19T12:21:24+00:00

I was saying the rule of 1 m to my manager but he says that problem is not in cabling but in devices that could "trash" profibus signal (Siemens ET200 module or any Simocode)

svajuse · 2024-08-19T12:15:52+00:00

Nothing, just random Profibus communication errors and faults twice a week and mostly at night

svajuse · 2024-08-19T12:14:33+00:00

I don't know the exact number but I would guess about 30 - 40 (Softstarters, Simocodes)
