Excuse me, please. I’m using Groov Server for win.
1、 How can I update the license file if the MAC address of this PC has changed?
2、 Will it cause HMI to be unusable for this reason?
3、Are there any emergency solutions?
I hope it doesn’t happen.
Could you explain what you mean by: “the MAC address of this PC has changed”? You can contact support@opto22.com for license issues/updates.
In general, though, if you’re running groov Server for Windows w/out a license (e.g. the “free trial” version), the only thing that stops after 2 hours is the communications to your various devices, e.g. Modbus, SNAP PAC. You can simply stop/re-start the server to get another 2 hours.
I mean, if the PC hardware is bad, or the network card must be replaced. Does this have to be associated with Opto22 technical support engineers? Or can I log in to the OPTO22 website to update the license?
Thank you
