PiLC based on the Raspbian distribution and runs on the Raspberry Pi 1B+, 2, 3 and Raspberry Pi Zero devices.
PiLC supports digital I/O (I/Q, E/A operands) on the Raspberry GPIO. The BCM-GPIO-I/O is handled via Awlsim's rpigpio hardware module. See the example project raspberrypi.awlpro for a usage example.
Experimental support for PROFIBUS-DP is provided via the pyprofibus hardware module. This can be used to read data from and write data to PROFIBUS-DP slaves via the PiLC PROFIBUS-DP header.
Just extract the SD-card image and raw-copy it to an SD-card.
Note that it does not work to copy the image into a pre-formatted SD-card's filesystem. The image brings its own partition table and filesystem, so it needs to be copied directly to the raw SD-card.
On a Linux host this can be done as follows:
7z x pilc-x.y.img.7z # Extract the image using 7-Zip dd if=pilc-x.y.img of=/dev/mmcblk0 bs=8M # Copy the image to the SD card
Where x.y is the PiLC version number and
/dev/mmcblk0 is the raw SD card device.
Note that on some systems you will have to use /dev/sdX instead of /dev/mmcblk0.
Communication via PROFIBUS-DP can be achieved using the pyprofibus PROFIBUS software stack and the corresponding Awlsim hardware module.
In the photo to the left hand side you can see a prototype setup of a Raspberry Pi 2 driving the digital inputs and outputs of a Siemens ET 200S PROFIBUS-DP slave. The Raspberry Pi controls the ET 200S via the PiLC example AWL program that runs in Awlsim.
- Q: How is PiLC pronounced?
A: It's pronounced like the English letters P L C. So just omit the i when pronouncing PiLC.
I am fully aware that this pun does not really work in English. But a native German speaker might get it. :)
- Q: Where can I find the schematics for the
Raspberry Pi Hat board?
A: The schematics and the full source code of the firmware is included in the Awlsim git repository and the release files.
- Q: Do you sell the Raspberry Pi Hat board?
A: No, I don't. But it is easy to build one by yourself. Just see the schematics. The RTC chip can also omitted, if an RTC is not required.
The PiLC scripts are part of Awlsim. A PiLC SD-card image can be built by running the pilc/pilc-bootstrap.sh script from the Awlsim package. Note that pilc-bootstrap.sh does only run on a Debian Linux host system (or another system that has debootstrap).
Latest bleeding edge awlsim can be downloaded using the Git version control system as follows:
git clone https://git.bues.ch/git/awlsim.git
|or via http:||
git clone http://git.bues.ch/git/awlsim.git
|or via git:||
git clone git://git.bues.ch/awlsim.git
or by downloading the
awlsim snapshot archive.
To browse the Git repository online, go to the git web interface.
A mirror of the repository is available on GitHub, GitLab, Bitbucket and on NotABug.org.
