Hi,
I want to control a MM440 frequency drive from siemens. The Master is a 315-2DP PLC. The drive is coupled on profibus.
I have Simatic Net installed and The WOrkstation is configured, but I didn't check the data yet in OPC Scout.
I want to connect my laptop on profibus and use some scada with visual basic and the OPC server.
I have tried to program something, but now; how can I throw my value 0-100 to a DBx.DBxx.x or Merkerword and how can I send the start bit ?
How can I get the actual speed; same problem; I need to read to a DB, but does anyone has an example of how it's done ?
