Scalability / I/O

Hello everyone
I have a question about the scalability of ProView, how much input and output can ProView manage? On this point, is it as efficient as Yokogawa?

Hi Benito,

Yokogawa's most powerful controller, the CENTUM VP, is designed to handle up to 15360 data points. It remains unclear how much control logic can still be processed and what cycle times can be used. So the question is not so easy to answer in general terms. BUT:
I am sure that ProviewR can easily exceed this performance – even with one runtime/controller. My largest project to date (building automation) has 4279 data points (Wago remote I/O), all of which are connected via Modbus TCP and processed with a cycle time of 500 ms. The entire system, including 16 operator stations that are accessed remotely and are always active, and including database recording in MySQL (approx. 2500), runs on an Advantec Uno 137 with an Intel® Atom® E3940 processor. The system's idle time is between 90–95%, with the ProviewR-Plc process occupying 10% on one core.
So there is a lot of unused capacity left here, and the performance of the hardware could easily be increased further.

Thank you for the feedback, I have more peace of mind, because I am deploying Proview for industrial processes and I want an extensible system with a large number of points.
Impressive your project. Without indiscretion, which country are you based in?

Hi Benito,
I live and work in Germany. I worked for Foxboro/Invensys/Schneider Electric in industrial automation for 17 years. Most recently as PLS development manager. In the course of this work, I came across ProviewR and, after evaluating it for many years, I realized that there is nothing else like it on the market. In 2016, I therefore started my own business to promote ProviewR in Germany and sell ProviewR-based solutions. In 2019, the state capital of Munich took notice of me. Since then, I have also been working in building automation, and we are trying to establish an open library for building automation (version 1 at proviewr.se/index.php/extern-modules ). This involves more than 1,000 buildings operated by the city of Munich. I have now introduced six MSR companies in the Munich area to automation with ProviewR, which are either working with me or independently implementing ProviewR projects for the LHM.
But of course, I am also continuing to work in the process and manufacturing industry and already have some interesting pilot projects there as well. I'm not sure, but I hope I can share my website here: www.ing-bs.de . If the entry is deleted, you can access the contact details via the “Martin's video” link if necessary.

Hello,
In the last year I did my first "big" system on Proviewr. This consists of a waste water management system, injectorwater supply for  pumps and other monitoring functions for the decontamination of 2 nucleair power plants.
The system has for about a 600 IO's, all et200sp, a few Grundfos pumps with a cim500 and a few Xylem pumps. The process nodes (redundant) are running on dell7010's which are way too heavy for the job, but it was the clients decission due spare parts and knowledge of the hardware. The same system load is copied and has a simulation (so all the pump curves, freq drives, water flow calculation etc.) and is coupled to the power plant simulator to train the operators.
The simulator runs on a VM and is even tested on a raspberry pi with a system load of max 4%. The pi isn't used just again to the fact of maintanence issues, When having a problem, a VM is a very fast way to recover the system without knowledge of the system, so an IT guy can handle this without the need of a service ing.
Since the system started only with the part of water treatement and grew towards the system today, I can say that scalability isn't far from an issue. The only thing that's missing is a good comparisation feature so when doing upgrades you can show that other parts aren't affected, but that's more a software qualification thing. Also I'm looking for ways to upgrade the system without the need for a full reload so the system won't go down when changing the logic in 1 PLC. But that looks to me practicly not possible (or every PLC would be anothe node).

Thank you for your feedback, I was able to visit your site and it is incredible. I also work to promote proview in France. I will take advantage of your expertise in the matter to have an opinion on the redundancy of proview. Is the redundancy of a process station mature? , I currently work in a single process station.
