Quantum 140 NOE771 00/01 Communications with Dual Port Client Device
AP7311 replied to AP7311's topic in Modicon / Telemecanique / Schneider ElectricHi Sir, Are you referring to the 192.168.10 domain subnet? It should fine on the device end. I am suspecting on the NOE IP config instead as the same config on another project but with Premium Unity PLC with different IP:192.xx for 2 different NOE is working fine. However, will need a Schneider expert to verify this. Thanks for the advise.
Hi, First of all, thanks in advance for those who support and advises. I have a Modbus/TCP operational network as shown below. However, at any 1 time only 1 LAN is able to communicate instead of both LAN networks of the device. In another system with S.E Premium Unity PLC, both LAN networks are able to communicate at the same time. Thus, I would like to enquire if this is a limitation of Quantum NOE 771 whereby only 1 LAN can communicate at any one time or whether I have missed out any parameter/configuration settings? Any issue on the IP address configurations? Please advise. Thank you very much for the advise and assistance.
Quantum 140 NOE771 00/01 Fault
AP7311 posted a topic in Modicon / Telemecanique / Schneider ElectricHi, First of all, thanks in advance for those who support and advises. I have a Modbus/TCP operational network. Last week a NOE 771 01 on one of my Hot Standby PLC System, Standby PLC stopped communicating. On its display the indication Fault, Kernel and Appl were illuminated. I replaced the card with a new one. It normalized but after a while it happened again on the same PLC. I tried with 3 new NOE cards but the fault remains. When I tested the card on a test system on my desk it seemed to be ok. The firmware and configuration is checked to be correct. What can cause this fault? Appreciate very much your advise. Thanks.
