There is a profibus master card available for the ocmpactlogix PLC. The mettler toledo IND560 communicates profibus also. Woodhead makes a gteway capable of going profibus to ethernet.
Yeah I was hopeing I could accomplish this without buying an additional comm card for the MT or the PLC, MT makes an Ethernet/IP card for that IND560 (found out yesterday). its less than $500, worth the investment.
