M340 Onboard Ethernet Communications


Thread Starter

M. Quintana

I have a number of M340 processors that I need to connect together through a dedicated Ethernet network. Can this be done with the onboard Ethernet ports?

We are passing values and states from one master PLC to other PLC's on the network.

Does anyone have any examples of logic built to do this?
You can use the onboard ethernet for comms but then you must use read/write blocks for communications and if not managed properly could cause hangups on the network.

A lot better to fork out extra money and buy NOE cards for each processor. Then you can I/O scan easily from and to every PLC. Even better (for me) is using the global data functions where you publish and subscribe to different plcs. Bmx noe 0100 supports the global data function.
