Hey, simaticmanager ! For energy meters on Modbus (at least those, that I have allready worked with) you normally need RS485 net and Modbus Master functionallity on your side. For direct connection to WinCC you then need at least: - RS485 interface on your OS (or at least 232-485 converter or USB- 485 converter)... - Running Modbus master, which can than provide your WinCC application with data from Modbus slaves (OPC or something like that). In my applications, I have allways did in on PLC! (communication procesor, CP 341 or CP 441-2 and then also a "loadable driver for Modbus Master" (code: 6ES7870-1AA01-0YA1) ). Then you have to write some code to communicate and prepare interesting things from energy meters on PLC and then send them to WinCC as all other tags!. have fun! uel123 P.S.: if any body knows any better (or cheaper!) sollution, please tell us! |
