Network Monitor Software being used on you 800xA and or Control Network
Our system is transitioning from Infi-90/800xA HMI to AC800M/800xA HMI. As such the network requirements are growing rapidly. Up until now we have been using Lansweeper to monitor our 800xA HMI network as it works well and is free. However with the addition of the AC800M Control Network and other supporting networks we are wondering what other users are using and whether they would recommend what they are using. What sort of alerts and reports are generated?
We are aware of ABBs PNSM software and it's integration wit the system as a whole, but is it worth it? Bang for buck?
AC 800M control networks mainly exchange telegrams of MMS type and occasional clock synchronization telegrams.
A network monitor like Lansweeper will probably work, but the amount of information brought out will be less (eg. ping response times). I've seen a handful projects using PingPlotter to record presence and response times on large networks.
Don't forget to have a look at RNRP which is onboard the AC 800M and most computers running Microsoft Windows in System 800xA; shortly a new RNRP tool will be released that will bring a few more network health details than the current RNRP Monitor can present. Currently, these counters can only be read on a per-node basis using the RNRP Fault Tracer command line tool.
PNSM Basic Computer monitoring is a complimentary service supervising the most critical resources in Microsoft Windows (CPU, disk and memory).
Some of the switches and routers in the ABB NE800 network equipment range have the possibility to monitor packet loss on all ports, incl copper connections. At a preset threshold, an asset monitor will trigger an alarm in System 800xA.
Regardless the choice of network monitor(s), the biggest problem (according to myself) is who shall receive and monitor the alarms fired from the monitors? I have plenty of examples where the alarm was properly raised but no one saw or reacted upon it.
