Hallo Talk members,
i have around 80 Raspberry pi running on Codesys Raspberry ML 4.0.1.0. I want to update them to 4.1.0.0 with a script/batch file instead of logging on each device. I think automation server may be a possible solution but not my present choice. Batch file / Script is ideal. Any suggestions???
Thanks in Advance
Singh
