any of the P.L.C. boffins out there I have 3 machines that I must get Going trouble is the control system is via a Siemens LOGO 230RCL they are approx 10 yrs old and I know that contacting Siemens would be futile as they will only want to sell me a new system what I need is the software ( program) and the dongle to connect the unit up to my computer so that I can read the program to see what the heck is going on as there are timers switching solenoids and a pump, fans and lights.I have tried to download the software from the net but Siemens obviously dont allow it I can only get an explaination on the operation of the unit,also the programming is in list or statement wich I am not familier with I have done some programming but in ladder. I will attach a picture of the plc it has 12 IPs and 8 OPshttp://www.theforumsa.co.za/forums/attachment.php?
I didn't find the right solution from the Internet.
I think that P.L.C. can be useful in the machine learning. However, I do believe that even more valuable would be the products of Anegis UK who work on the machine learning professionaly. One of such incredibly useful programs is dynamics 365 - ax-dynamics. Did you ever try it out?

I did not intend to make any spam, sorry. It's just that they're working on machine software as well and it might be that some differences between those two have eluded me. I'm still pretty new to the IT market and I've a lot to learn. I just thought that I would share something I found interesting.

Hi wakrzen: Yes it is eluding you. They specialize in ERP (Enterprise Resource Planning) business software systems, like SAP is. PLCs control Industrial machines, they are an industrial microprocessor that uses specific industrial programming languages like Ladder Logic (and PACs using Structured Text) for example. Even HMI/SCADA which is just software, controls industrial machines. Just to a lessor extent than PLCs do.
In recent years, more focus has been towards PLC/HMI/SCADA interfacing with ERP software programs. Which is basically the same as those industrial systems sending data to a MS excel spreadsheet or any other computer software. They don't control industrial machines.
You can not replace a HMI or SCADA software, or a PLC with ERP software(Your brand or SAP), it won't do the job of controlling the industrial equipment.
A typical configuration might be PLC sends and receives data from SCADA, SCADA also sends data to plant ERP software for business management, accounting etc. PLC <-> HMI/SCADA -> ERP
(Extra warning note: If ERP = Cloud, then ERP Data <-> World via Internet)
Hope this gives you a better understanding of the difference between industrial PLCs and ERP software.
