How can I see if the communication network is overloaded?
Use "CX-Supervisor Performance Monitor Tool" to see if the network is
overloaded
This tool is available in the CX-Supervisor run-time by right clicking and
selecting Performance… ( if security privileges allow). It can be used to
see how much of the available bandwidth is in use. You can also see how
many points are waiting to be processed and the latency of actual
communications. To improve responsiveness try to reduce the bandwidth
used, the latency and the number of active messages.
Note that performance begins to reduce well before 100% saturation is
achieved. For example it is rare to achieve more than 70-80% for a serial
connection. This is analogous to a motorway where cars slow down long
before they are touching bumpers, and might only achieve a maximum of
50% capacity (i.e. each car has a car length space behind it).

How does the Operating System affect performance?
On the same specification machine Windows NT provides the best overall
performance. It is understandable that newer, larger Operating Systems
run slower on the same specification machine. This is not usually a
problem as newer operating systems are usually delivered on newer
specification machines.
FINS Gateway drivers for particular networks operate consistently across
all operating systems.
OMRON recommend Windows 2000 and Windows XP Professional for
the following reasons:
- Better security
- Better stability
- Better multitasking
