Hello All,

I have bought two raspberry pi based plc units sometime back. Last month I bought a runtime license 'Codesys Control for Raspberry Pi SL' and got an activation ticket from the team. I activated the license and installed it in one of the raspberry units which was successful. Now this morning I tried to load the same license in the other unit but I got an error '10957 [10957] - Ticket contains no open licenses for this firmcode'
Can anyone tell me what it means or what am I supposed to do? Does it mean I need to buy a runtime license for every raspberry unit? Can't load the same license in several units?
