Is there anyway to trigger a safeguard reset using dashboard server?
I am using dashboard server from my PLC to do things like start/stop programs and reset E-Stops, but I can’t find a straight forward way of reseting safeguard stops.
Here are some things I did find:
1: If I change the operation mode to automatic, and then immediately clear the mode, it resets the safeguard reset. This seems kind of “hacky” way of doing it, and I worry about changing it to automatic mode and it getting stuck in that state when I don’t want it to. But from my test it does get my end result in a round about way.
2: I am also using profinet, although I haven’t tested it, I believe I could wire two digital outs into the configurable Inputs and set those inputs as safeguard reset. This also seems “hacky” and anyone looking at the wiring would have some serious questions.
Can someone point me to a better way of doing this? I imagine its not intentionally left off based on safety concerns since dashboard server can be used to reset E-Stops and Protective stops… So is there something I am missing?
The correct way is your 2nd method. You should indeed connect two 24V signals from the PLC to the Configurable Inputs assigned to Safeguard Reset.
There’s nothing hacky about that.
I don’t think there’s a way to reset safeguard with the dashboard or PROFINET protocols.
I realize I didn’t describe #2 very clearly. I meant that I could use two outputs from the UR robot, and wire them to two config Inputs of the UR robot. Then use Profinet to pulse the two outputs.
I basically want to avoid running additional wire from my PLC to all of the UR robots we are using on this project. I am hoping to use my ethernet network for all of these resets and control.
After better describing #2, does it feel like a good solution still?
I have used the dashboard server to reset safety; the command ‘restart safety’ causes a restart. Use ‘close safety popup’ then 'restart safety, ‘power on’ and ‘brake release’. At least you can use existing network without additional wiring. Obviously for non regular occurring events.
Wiring two outputs from the UR to the reset inputs does indeed sound a little hacky.
But I guess that’d be the only way to do it, if you want to reset the safeguard without wires from the PLC.
I would reconsider wiring from the PLC to the robot, though. Above is too hacky for me, too.
Alternatively, if you are using an e-series robot, they now support PROFISAFE which lets you do everything safe-related through the PROFINET connection. It requires a paid license, though.
