Helpful Troubleshooting Tips for PROFIBUS Projects (plus 5 common mistakes to avoid at all costs)

How can I find out if a device can be operated with two redundant masters?

This can be easily determined from the GSDML file. If this entry is present, it works:

• NumberOfAR="2"

How can I set up a new IP address?

You can use the PRONETA tool to set up a new IP address.
Take a look here: Configure PROFINET Device

I can’t connect to the device via the IP address. What could be the reason for that?

The reason for the inaccessibility could be that the device is trying to get an address via DHCP (not DCP) because the address configuration via DCP wasn't done with the flag 'permanent'.

Do you provide a PROFIBUS simulator for master-slave communication?

We do not provide any simulator for the PROFIBUS communication

The connection between the control and the PROFINET slave KUNBUS gateway is established. However, no process data is exchanged. What can I do?

Check the address range for communication with the RevPi → Check the offset.
The start address must be set to 0.

I have a PROFINET GW. In PRONETA, I am shown stack version 1.1, but the latest Firmware version is 1.5. How can I update the system?

Stack version ≠ Firmware version. Check the correct version that your device has.
