Hi, You can control MM440 drives using Profibus-DP or USS protocol. Your CPU has MPI only. So you need communication processor (CP). For Profibus-DP you need CP342-5 and for USS or Modbus you need CP-341 (or CP-340 if you write driver by yourself). If you decide to use profibus, then you can find examples of controlling Micromaster drives here: http://support.automation.siemens.com/WW/view/en/22078757 http://support.automation.siemens.com/WW/view/en/22318171 If you decide to stay with USS or Modbus then don't forget that you need to write driver by yourself (for CP-340, CP-341) or you need it to buy from siemens (for CP-341 only). |
Best regards, |

Okey, thanks all. I decided to use Profibus DP cause i also have to use an ET200 for distributed control. |
