Dear All:
There are two PLC devices with NOE 771 0x Ethernet module. One is responsible to collect data from I/O sensors, the other is redundant.
After I send a packet with function code 0x10 (WriteMultipleRegister) to PLC which collects data from I/O sensors via Ethernet, I receive a normal response. Then, I use the web utility to watch the I/O address which I want to write a value into, but there is nothing changed. That I/O address doesn't be used.
