Profisafe watchdog timeout with PLC

Robot Controller OmniCore
1

Hey looking to get some help on an issue we’re running into setting up a new omnicore controller with profinet/profisafe to a siemens PLC. Using robotware 7.18.2. Both PLC and robot have the GSDML-V2.43-ABB-Robotics-OmniCore-20240821.xml file which we located in the robotware folder as per the manual instructions.

Using 32 byte DI/DO and 8 byte SDO/SDI. Set up the network on the LAN port, correct IP, same name as it’s set on the PLC, correct source and destination addresses. PLC can recognize the DI/DO, but getting watchdog timeouts on the SDI/SDO. At one point the SDO was working and just the SDI was timing out.

Anybody run into something similar or have any tips/pointers? Kind of spinning our wheels here. Thanks in advance.

Hi Droman92,

We are having a similar problem here. Did you manage to fix it?

What I found was the IO Engineering tool doesn’t fully write the safety configuration so you need to write with IO engineering and then also in the SafeMove configuration. So my workflow was to to do a write with IO Engineering tool, restart, immediately go to SafeMove and do a Write Configuration, restart, and that did the trick.
