Senih Posts: 10 Rating: (0)	Hi Guys can you please assist i am are experiencing problems with connections between a S7-200 PLC and a S7-1200 PLC to a MP277 8” Touch HMI Panel. Communication from S7-200 to HMI is via Profibus and Communication between S7-1200 and HMI is Ethernet. I can download through Ethernet and the program is loaded to thePanel but as soon as we want to start it losses connection to the S7-200 PLC. But if we break the connection to the S7-1200 it establishes connection to the S7-200 In WinnCC flex all the setting is correct so that the HMI looks at both PLC’s. any ideas please.
