Options needed for connecting s7200cpu226 & mm440

RICII Posts: 34 Rating: (0)	Hello, I need to connect a s7200 cpu226 to a micromaster 440 drive, what options are available? I need to change speed and initiate stop / run conditions. I have read through various documents and I'm a bit puzzled because some say I can use a profibus connection, some say I can't. I must use the CPU226 and the MM440 as this is specified in the brief. Anyone? Thanks, Ricii

A S7-200 can only be used as an Profibus slave. You can use USS protocol, see this link: http://support.automation.siemens.com/WW/view/en/12462284 Or this link: http://support.automation.siemens.com/WW/view/en/6042107 Best regards, Wizard
