AllenBradley PLC Polling Driver (Ethernet)

KpLibPlcTag

The first one went. Tested on MicroLogix 1400 PLC.
So far it works only on Windows, tested it on x64 architecture, but it should work on 32-bit too.
For Linux, you need to do a separate build.

Cool!
Should I add the driver to the repository?

[manjey73]

Yes, you can add it. I give out keys for free without a time limit. Perhaps I’ll post the source code later.

Hi
is it possible to use this driver on raspberry?
Thank you.

Possible. The developer has experimental builds for libplctag_2.3.4_linux_arm6hf_EXPERIMENTAL.zip and libplctag_2.3.4_linux_arm7l_EXPERIMENTAL.zip
If any of the builds are suitable for Raspberry, I can try to rebuild the driver for them. But I unfortunately have nothing to test on. I have already returned the PLC and I do not have access to it. If you can arrange remote access to the PLC, I can try to check this possibility.

My Raspberry uses a BCM2835 processor which is an ARMv7 Processor rev 4 (v71) I used the cat /proc/cpuinfo command

Hi,
i have the same version of raspberry.
I tried to run an example contained in the library, I have this error:

pi@raspberry:~ $ ./simple
./simple: error while loading shared libraries: libplctag.so.2.3: cannot open shared object file: No such file or directory

The libraries libplctag.so.2.3 is in the same directory as simple.

Thank you for your help.

[manjey73]

libplctag.so this library should be located either in the /lib folder and probably should be registered in the system (I don’t remember the nuances now) But that’s not all, in my library there should be a call to the libraries of Linux versions, the build should be under Linux

[fedex]

Hi,
I solved with:
export LD_LIBRARY_PATH
Thank you.
For windows LibplctagWrapper.dll uses plctag.dll.
What needs to be changed to use libplctag.so.2.3.
Thank you.

[manjey73]

For Linux, I will need to rebuild the library KpLibPlcTag.dll I’ll try it this weekend.
If possible, I’ll post a link to the Raspberry version here

Ok.
Thank you.

KpLibPlcTag_for_Linux

I can’t check it, because I don’t have a PLC on my hands. I downloaded version 2.3.4 And renamed it libplctag.so.2.3.4 v libplctag.so and put on the path /usr/lib I do not know how true this is for working on Linux. Version 2.3.5 has already appeared on the developer’s website

https://github.com/libplctag/libplctag/releases

The library calls exactly libplctag.so Please write, will it work or not ? And if anything, write to the mail with the computer code, so that I can make a key.

[fedex]

Hi,
it worked by only copying the libraries to the /usr/lib directory.
Thank you.

[manjey73]

Do you need a key for the driver or do you do without it ? 🙂
