Delay to apear trends in the trend display
I have problems on a link to a controller ( AC450 ) .My trends takes appears on the trend display and the status of the trend is flashing yellow, to begin to appear. the trends take on average 20s to appear and when I connect with ONB , it takes between 3 and 4 minutes. The transceiver in the CS 513 is flashing colision led almost all the time .
Does anyone have any idea what might be going on?
AC450 with 800xA 4.1
If SLTARG takes long time you may have a network communication problem.
Try replacing the transceiver and other equipment connecting the AC450 to the network. All items should be investigated. If you have spare ports, cables, transceivers, etc. try swapping them to see if the problem follows some hardware, or is constant.
Depending on hardware revision, the AC450 might be subject to a problem: See Product Bulletin 3BSE030979
The early PM511 versions have an issue when using SC520 carrier board. Before Revision C, an interrupt could go lost and the SC520 was then in polled in what we could say "limp home mode". In this polling mode, network traffic in/out of the AC450 would slow down significantly.
I have attached a procedure with which you can confirm the problem and also a temporary workaround. Permanent solution is to upgrade to PM511 PR:C or later. Downgrading to SC510 would also workaround the problem; but controller load would rise and the network disturbance protection with SC520 will be lost.
