Hi Nicolai,
thanks for your reply.
The PiBridge has RS485, some sniffer pins and Ethernet as far as I know. Do you know which pins are used for communication with the gateway?
Are there any schematics for the PNIO gateway?

Hello, can anyone tell me what the physical interface between the Gateway (PROFINET) and RevPi Core looks like? Specifically, the aim is to isolate the Ethernet side from the PLC from security purposes, i.e. get data from the PLC without exposing it to the network that the RevPi is in. Therefore, if...

Works! sudo chmod 222 /sys/class/gpio/export /sys/class/gpio/unexport echo "41" > /sys/class/gpio/export cat /sys/class/gpio/gpio41/direction echo "out" > /sys/class/gpio/gpio41/direction echo 1 > /sys/class/gpio/gpio41/value Changes the resistance between the A/B pins from ~ 200...

Thanks Dirk, pins it is then.

I will give it a try soon, expecting 120Ohms or high impedance on the A/B pins depending on the output settings of GPIO 41.

Hello, I'm no security expert, however I assume in an industrial setting (particulary a remote industrial setting) that it would be quite easy to read out the image, mount it on another machine, play with a bit and reinstall it. Is there some way to prevent the image being read out (I only known loc...

Hello, RS485 seems to work easliy between two RevPi Cores using the PiBidge. I notice the termination resistance is connected to GPIO40 and I assume contolled by software. Given that I have disabled piControl in /etc/modules on all RevPi Cores, is there a good (recommended) way to control the termin...

Hi lukas, thanks for the answer! I guess I now have the problem that the Ethernet connection via PiBrige works *too* well. The original idea of isolating the two networks will not work because I have a chain of Ethernet connections between the internet and the cusomer network. I guess one optoin wou...

Hi, I suppose this is a software question. The idea is to isolate the cutomer network from the internet (LTE router), but still log data from it. On the left side, you have the Edge device, connected to the cloud via LTE, on the right side, you have a data logger, communicating with the local networ...
