I agree with m.prestel. As you didn't write with which PLC you tried it, I would recommend to test it with the Control Win Soft PLC under windows. This way you can prove, that you did everything right in your project. If it doesn't work on the target, it would be interesting, which target that is. Cheers, Ingo
No tutorial I know of. But AFAIK the GPIO driver, which is included fits for all analog and digital GPIOs, which are accessible through the sysfs. And other external busses, like ethernet or CAN should also work, when there is a linux driver for the device. Cheers, Ingo necatibilgin firstname.lastname@example.org schrieb am Sa., 11.

Hi! Those events are scanned in the Scheduler interval, which is by default 1ms on most systems. But those events are not useful for fast reactions. Some systems provide so called "external events". Those can be better compared with " interrupt handlers". But the raspi has no support for that. Your only chance is a quick cyclic task, in which you execute your code. Cheers, Ingo
Currently I know no real successor. But (as a teaser) for SP18 I saw already concepts for defining constants per FB instance. With this it will be possible to scale buffers for each FB instance. I believe that this will substitute most uses for library parameters in a much better way.
