If I wanted another application to also read from it I would be going through all of that again.
#WHAT IS KEPWARE DRIVERS#
Now if I wanted to talk directly to a PLC I can get the drivers for it, read through the documentation, find out how it works and use that to talk to the PLC, but I would have to do that for every device I get, if I have two different brands I would have to deal with all of that twice if not more. OLE is the thing that allows you to drag and drop between microsoft word and excel for example I don't have to worry about how the application actually works if I want information from it, I use an interface to link it to my application, and with that I can pull information from it, and send information to it. Now OLE is this, but between applications. Or if you send a package using the postal service, you don't have to worry about exactly how it works, you just put an address on it and send itĪ COM port is this type of thing for hardware
Just like a operator using an HMI presses start and doesn't have to know exactly how it works physically.
#WHAT IS KEPWARE SOFTWARE#
A com port is great because if I want to write software that uses that converter for example I can define a com port, link it to the hardware and send/receive data to it without worrying about send and receive buffers, when the clock is initiated and how it physically sends the information, I have this nice "interface" that I deal with instead
#WHAT IS KEPWARE SERIAL#
If you have had to use a usb to serial converter you have had exposure to a com port. OPC is OLE for Process control, or at least that is how it started out, OLE is object linking and embedding, and is based off window's COM technology, and this is where COM ports come in.īare with me here, I know the above part is all gibberish Please click "report" on spam Related sub-reddits: (*) At mods' discretion, certain self-promotion submissions from people who contribute to this sub in other ways may be allowed and tagged with the "Self-promo" flair Job offers and requests go to the weekly thread.No shit posts (memes - pictures with superimposed text - are OK).If asking a question, ask the actual question, fully yet concisely, right in the title.Be civil: do not insult no all-caps, no excessive "!" and "?", please.Job announcements (oustide the monthly job thread).Single Board computers: r/Raspberry_pi, r/Arduino, r/linux_devices, r/linuxboards.
