Kinetix 5700 Networking Issue

[maexio]

Hey VoteCoffee - we were using Ntrons, and had to move away from them due to CipSync issues, we have eventually settled on PlanetTechUSA as they are gigabit, managed and support CipSync. Even Had the AB guys at our office for a test of one to verify it supported CipSync.

Nice! I liked their IGS-20040MT, and at $700 it's half the price of some of the other IEEE 1588 switches (such as stratix 5700 1783-BMS10CGP, NTron NT24K-DR16-DC-PT).


One of the benefits of a IEEE 1588 switch is that you can use VLANs without screwing up the CIP Sync.


AB's got a decent article that covers some of the gotchas though.

One of the big issues I run into is that if the PLC can see a grandmaster clock that the drives cannot, then it refuses to be the master clock for the drive.


I found out that on a dual port PLC, you can individually enable and disable cip sync for the port using a message instruction. This allows you to create a local cip sync network for motion that is isolated from the broader network.
Seems like an ideal way to create local time sync isolation without having to add an expensive switch with cip sync capabilities to act as a boundary clock.

Hi, folks!
If the question are actual, A-B made firmware 11.003 and fix annoying connection problem. You just need to update your Kinetix drive.
