we have a plant with this specification:
1) 4 Redundant controller unit of PM864a
2) with ASpect, connectivity and Domain Server in redundancy
3) 800xa v5.0.1
so there is lag problem in operator monitoring between pages
and there isn't automatic system backup
can you help me?
- The upgrade procedure is not simply plug and go. There will be some engineering required. More or less according to your current system configuration. Probably you also need new Windows server hardware.
- The upgrade is not "free". You need to already have or purchase a software upgrade or support agreement of some kind.
Exact answers for your individual system are not possible in this forum. You should contact your local ABB agent or Channel Partner to discuss in detail.
if your system was working fine before, then no need to just go upgrade because you are having issues.
1. Defrag your aspect system
2. Defrag your hard drives
3. make sure DNS is resolving correctly.
4. check Windows memory usage - sometimes these systems run for months on end without a reboot
5. check your network traffic
6. check your network cards are connecting at the highest speed available (NIC config and network switch port config)
7. Use good CAT5 or CAT6 cables on your network connections - this can have a serious impact - you will only see the difference once you install decent cables
8. Disable LLMNR on your control networks using domain policy (google will show you) - this can cripple control networks - this has a remarkable impact
9. Check IGMP snooping is disabled on switches
if you are running PG2 graphics, then motion items (like conveyors) can slow displays down - i have a SV5.1 system that was slow until i removed motion items.
V5 has a built in system backup - it is a combination of service structure and maintenance structure aspects you need to configure.
i run this backup on each aspect server once a week, AS1 sunday, AS2 tuesday and AS3 thursday. I pull these files to a NAS the day after using syncback.
Only thing is you need to maintain the older backups (delete) about once a month because the storage grows.
Maybe yes, maybe no. Can't say for sure. If the system USED to be fast enough, then probably it can be fixed.
Right Click on the graphics and check the diagnostics. Open the timings tab to get an idea of where the lag comes from.
Increasing I/O count increases CPU load ( actually its more complicated ) but should not slow down the graphics update time.
Without a site survey and some engineering time it really is not possible to say why YOUR system is slower now.
An upgrade to version 6 might, or might not fix the lag problem. But even so this is still a good idea. There are other equally good reasons for upgrading.
