Have you looked for an open source ladder editor that could be re-used?
I googled "open source ladder logic editor" and got a few hits.
Have you seen this project? Apparently this was derrived from the
Puffin PLC project that was started years ago.

pyprofibus is not restricted to any hardware.
It has a shim PHY layer that can be adapted to anything.
It currently ships with

I've written and debugged my fair share of AWL... but I can program logic a lot
faster in LAD.

I agree. Being able to use Profibus with LinuxCNC would be very

Authur of pyprofibus used an ET200S module.
I tried pyprofibus with RS485 and an Siemens ET 200L-SC, I get answer in first
step but in second step for request diagnostic module does not send answer. I
have several other profibus devices and they are very common but it is not top
priority to get
I downloaded the Windows version of awlsim.
Its very impressive.Regarding the Profibus interface; Are you
using a RS232/ RS485 converter to connect to the Profibus I/O block?
Is the methods of configuring a Profibus drop documented some where?
I do Step7 programming but mostly in Lad/Ladde

Then trying to get raspi-profibus to work on an ordinary PC I discovered there
is an awlsim hal module suitable for PLC programming. It would be good to know
if anyone are working with awlsim? Or profibus right now?
The raspi-profibus software is divided in two. The higher level is written in
