I have a Schneider M340 PLC with a modbus processor BMXP342000 and a ethernet NOE110 card. The modbus port is used as Master to communicate with several modbus slave drives and softstarts. My ethernet NOE110 is used to communicate with several schneider OTB's deported IO with IO scanning. Now I have a GEfanuc Quickpanel HMI that I need to hook up to this equipment. Since the HMI is master can I communicate between the quickpanel and the ethernet NOE110 passing through a schneider 174 cev 300 10 bridge?
 
Yes that will work. It is only modbus serial that can have only a single master, that restriction does not apply to the ethernet port
