Re: [foxboro] AW: CP Load

Andeas,

Could you fill in more details here?  I've used the CP station monitor
display on CPs with 0.5, 0.2, and 0.1 second BPCs and found the information
presented to be helpful in balancing phase loading.  One issue I am aware of
is that the IO scan loading is not necessarily correctly synchronized with
the other loads measured.  If there's a significant number of FBMs on the
station (i.e. 30+), the "total control cycle load" tends to artificially
shift from scan to scan, making it tough to determine which phase the load
is coming from.  There's also a resolution issue with 0.1 second BPC
stations, making it tough to distinguish load fluctuations less than 10% if
I remember correctly.

The CP station monitor shows the right load only when you choosed a =
station BPC of 0.5 seconds.
