Using 1756 EN4TR in 1756-L7 Processor backplanes?

PreLC · Jan 7, 2021

Hi PLCs.net!

I was wondering if anyone has been able to leverage the bandwidth advantages of EN4TR Network cards with L7 processors?

PCDC says they are compatible, but just wanted to know if it's truly going to work:

If it can be added to an L7 tree, it should work.

Thanks for the response,

While that is true, I just wanted to know if the bottleneck for the communication lies with the overhead timeslice value in the controller properties?

Would it really give results?

EN4TR is fully supported in all L7/L8 chassis except local Redundancy chassis.
It gives you better packets per second values for I/O and HMI

Awesome!

Do you think upload/download times are improved too?

I don't know, most likely not.

Haha I'll report back if I find out.
