Hello to all,
I'm testing 4Diac since a few days, and I've built a Program with Ethernet Connection.
That means two Forte-PC's in one Network, if I press a button on the first one, a led lights up on the second one. index.php/fa/33530/0/

(this is the 4Diac program).
Now my questions:
I want to get the same results but over CAN-Bus. Is it wright, that I can use the same "schematic" as in my Ethernet program and what do I have to write at the ID-Pins?

hi,

for that you would need to write a CAN driver for FORTE. FORTE has a very flexible communication architecture allowing you to easily expand the supported protocol. Please have a look into the communication development documentation on our web-page for that. But with that you can have the same FB network and just change the paramters of teh publish and subscribe blocks to switch between netowrks.

Similar for the IOs you also need to write a driver. Unfortunately we don yet have good docs for that. You can have a look at the code in the sysfs model for getting started with a very simple IO driver.

Cheers,
Alois
