Susanne_D Posts: 7 Rating: (0)	Hi everybody Do you where i could find the MODBUS_TCP_CP library, i need to configure a Modbus connection between a CP443-1 and an external system which supports the Modbus protocol. Is it necessary to get the S7- open/Modbus licence ? Thanks for your Help Regards Suzanne

A demo version you can download here: www.siemens.com/s7modbus => S7 OpenModbus/TCP, tab "Downloads". Wüstenräuber
