AC800 M controller Time sync with 800xA and compact solution

Hi,

We have 10 controller in 800xA system PM866 and PM864.

Out of that 2 are CNCP master and rest of the 8 are synching without any issue.

We have another 4 controller in compact solution which is also configured same as other 8 controller to sync time. But these 4 controller are getting warning 'No Time Sync'.

These 4 controllers are in the network and they are communicating with all other controller in IAC.

On opening Tools/Maintenance/clock Sync Status from the compact controller I can see the time difference is 0ms with first Master and few micro seconds with second master.

But I cannot see or I cannot add theses 4 controller in time sync under tools /Maintenance/timesync.

Attached is the screenshot from 800xA.

IP ends with 203,204,205,206 are the culprits.

Any idea of these behaviour ?

CNCP need RNRP. Verify that all controllers are visible on the same RNRP area in the RNRP Monitor.

CNCP is multicasted = no routing possible (controllers must share same IP-subnet).

Also, verify that IGMP is disabled in the switches.

Cannot see the these controllers in RNRP.

It share same subnet.
How to add those in RNRP ?

1. Read the entire RNRP chapter in the Automation System Network manual
2. Examine / harmonize settings in all controllers
3. Ensure IGMP is DISABLED in physical network

All the controllers are having same settings.
Still not available in RNRP.
Its unmanaged switch .

If settings are the same (remember there are 3 locations: Base(0), Eth.1 and Eth.2) except for node number a lot points to the network not passing thru multicast traffic.

IGMP is a known multicast suppressor; it must be disabled.

Still, haven't heard of any unmanaged switch with IGMP.

Can you try replacing the switch?

Or temporary move a not listed controller to a switch where a listed is currently connected?

Dear Stefan,
I thin it is not Switch Issue as we have Other controller which are in 800xA system and is in RNRP. Since the switches are unmanaged there is no configuration for IGMP.

Any ohter option to add these controller manually in RNRP ?


By Stefan Stromqvist on 7/26/2017 | Like (0) | Report

No.

1) Have Wireshark installed in a portable PC or MAC.


By Stefan Stromqvist on 7/26/2017 | Like (0) | Report

2) Connect portable to same switch as controller
3) RNRP shall send multicast packet to 239.239.239.x on UDP port 2423

Wireshark should notice one such message per second from every node incl controller.

If not, place a hub between portable and suspect controller and check again.

Pay attention to Source IP as each node is sending to 239.239.239.x
This test will tell if RNRP works in controller or not.

An error in Ethernet settings could cause RNRP to not work in controller. Be extra careful when conparing

RNRP Fault Tracer/Utility have option to "Check settings in one node, IP=a.b.c.d". Use it to compare between working and not working controller.

Thanks
It's a solved, we missed the RNRP on the second row of the Controller HW.
THANKS
