30+ Ethernet nodes
Hi guys…looking for some insight here. We are quoting a line that will use 12 different pumps to dispense product. 2 servo Axes per pump (1 for pump and 1 for rotary cutoff noddle) so 24 servo axes there. There are times that all of these pumps could need to run at the same time. Add in a few more servos for conveyor, traveling head, etc and we are looking at about 30 servo axes.
We’ve had good experience with Kollmorgen with CIP Sync. There will also be (3) different ABB 6-axis robots used along the line to move product around. Various I/O here and there, maybe some IO Link on the EOATs.
Customer has specified Allen Bradley and Kollmorgen as our options. The 5069 L330 or L340 can handle this number of Ethernet nodes per the data sheet (CIP sync doesn’t actually require an -M motion controller)
I’m not the best-versed in Ethernet traffic, RPI, etc…..does this much Ethernet stress a 5069 more than it would a 1756? The pump/cutoff combo will always be cammed together. I would think managed switch would be a must here.
Should I split this out between controllers? It would be 4-5% of the overall cost to add another controller.
