Hi folks,

I have a question about TCP keep alive intervals. According to everything I've read, for CompactLogix it's supposed to be 8 seconds. However, everything I've seen from wireshark captures show 13 seconds. Has anyone seen a similar time?

It doesn't seem like a big deal on a device with an 20ms RPI or 50ms RPI, but for a device with a 1 second! RPI (don't ask), it is a big deal, since the keep alive interrupts about 2 seconds of data..

Thanks in advance...
