CI855 as Clock Master on MB300
Hello.
I have time sync issues.
My system (how I want it):
Controller 1, PM891:
- receives time from SNTP
- sends CNCP-time as CNCP-master 1
- CI855 as MB300 ClockMaster on MB300-net 12
Controller 2, PM864:
- receives CNCP (CNCP-master 0)
- CI855 as MB300 ClockMaster on MB300-net 12
Controller 3, PM866:
- receives CNCP (CNCP-master 0)
- no CI855
Controller 4, PM891:
- receives time from SNTP
- sends CNCP-time as CNCP-master 2
- CI855 as MB300 ClockMaster on MB300-net 11
800xA system 1:
- combined AS/CS
- AC800Connect
- AC400Connect
- RTA CLS1-setting 0,2,0
- Reverse_sync_mode = false
- two AC450, both CLS1-setting 0,2,0
800xA system 2:
- two AS + two CS + IM
- AC800Connect
- AC400Connect
- RTA CLS1-setting 0,2,0
- Reverse_sync_mode = false
- three AC450, all with CLS1-setting 0,2,0
The two 800xA systems are independent from each other.
One Control network for all CS/AC800M in both systems.
One ClientServer network for all AS/CS/Clients in both systems.
MB300 nets 11 and 12 is totally separated.
800xA system 1 works. Time diff between PC:s is < 20ms, and AC800M seems to have the correct time.but AC450 does not seem to receive the correct time.
800xA system 1 does NOT work. When I set CI855 on Controller 1 to be MB300 ClockMaster (on MB300-net 12), nothing happened. I could NOT see that AC450 adopted correct time.
When I set CI855 on Controller 2 to be (second) MB300 ClockMaster, all AC450 (on MB300-net 12) got their clocks set to 1985-07-08/19:49:XX!!!
Is it wrong to have two CI855 as masters on the same MB300?
Book (System 800xA NetworkConfiguration System Version 5.1 3BSE034463-510 E page 16+0) says "it is recommended to use a CI855 in AT LEAST ONE AC800M so that the time can be distributed from the Control Network to MB300 via CI855"
Why wont the AC450's get synced?
Anyone has a clue?
Thanks

This is a problem. By Definition Net12 is the Redundant network for Net11. If this is a totally separate network it should be Net21. If the system time will not synch on Network 12 I'd be very suspicious that this is related.

Minor correction,
It should say: 800xA system 1 does NOT work.

What is the CI855 setting made in Control Builder M?
With ”No sync” you could theoretically push a wrong time if you are able to startup the clock sync task (see next section)...
1. Use a valid sync direction setting (800M -> CI855) in CBM project
2. SLTARG to CI855 from CS node after DFTARG -1,-1 followed by TSESS, then CTRL-B
3. Check CI855 time with RDATIME. Abort if wrong and go back to step 1.
4. Check CLS1 (FINS 218,1 followed by GINS)
5. Check sync state with: LOCPSET CMDS:TP02.CT followed by LCLKP
6. If necessary, wake up master with RET CXAE000,10
7. Repeat step 5.
8. Check all other nodes with respect to steps 4 and 5. LOCPSET does not need to be repeated.
Two CI855 can have 1,2,1 setting per network. One will act master, the other backup. Do not issue step 6 in more than one node per network. KIT/ACT can be used to bring down an undesired master.
Be very observant on system messages, revert with full detail if you should see clock related messages.
