Multiple Ethernet/IP connections

philhoward

I'm not sure how or why I have this problem, or even if my fix is correct but it seems to work..

 

I have 6 slave devices (from 3 different manufacturers, Hilscher, HMS and Allen Bradley) on Ethernet/IP (on an IRC5) and the only way I can get them all talking at the same time is stagger the startup of (at least) one unit - set to Disabled on startup, then enable the unit 30 seconds after the background task has started.

 

Question 1 - Why do I need to do this in the first place

Question 2 - Is there a better way to do this - should I start all the devices one by one?

 

This isn't a problem i've seen before - IO tends to work or not!

 

Any suggestions welcome as the full systems may require upto 20 units (the maximum)!
