Hi, everyone. Our system have two PLC CPU(1515-2PN) and each PLC CPU have their sub-device. Please refer attached file to understand network. To merge two networks, we connect it with cable and set subnet-mask number. #1 PLC IP: 192.168.1.50 subnet mask 255.255.0.0 #1 Sub-device IP: 192.168.1.120 subnet mask 255.255.0.0 #2 PLC IP: 192.168.2.50 subnet mask 255.255.0.0 #2 Sub-device IP: 192.168.2.121 subnet mask 255.255.0.0 Connecting two network is working well after each PLC CPU finish finding their sub-device out. However, when turn on the all system simultaneously, each PLC show error message. The error message says PLC can not find sub-devices. To assign each sub-device to their PLC CPU, we should disconnect two #1, #2 network physically. Then it should be connected after each PLC CPU find their sub-device. How to fix this situation?

Model neme is S7- 1500 1515-2 PN (6ES7515-2AM00-0AB0). Two PLC CPUs have same name (General name and Profinet name) Some each network sub-devices have same name. However, IP address is not duplicated. Should I rename general name or profinet name? |
