hello popciprian; Do you mean that you have 2 TD 200 on your S7-200 CPU, both occupying a different portÉ? If this is the case, you should know thatcan setup both on a single network, under certain conditions (using Profibus cable and connectors, providing external power for the TDs, modifying addressing in the PLC...). The following FAQ will guide you through the process: http://support.automation.siemens.com/WW/view/en/22723014 This would free one of the ports so you can use it for USS communications with your drive, as Profibus control is not possible using the EM 277 (it cannot act as a master on the bus, therefore cannot read/write to the drive). This FAQ will show youhow to purchase the S7-200 USS protocol, and where to locate documentation on the subject: http://support.automation.siemens.com/WW/view/en/17470979 Hope this helps, Daniel Chartier |
