I5049 Data Gathering Period
Range:
0 - 8,388,607
Units:
Servo Cycles
Default:
1
I5049 controls how often data is logged from source addresses when data gathering is enabled, in units of
servo interrupt cycles. If I5049 is set to 0, data is logged only once per data gathering command (single-
shot mode).

Normally, this parameter is set automatically by the PMAC Executive Program’s
gathering and tuning routines.

I5050 Data Gathering Selection Mask 1
Range:
$000000 - $FFFFFF
Units:
Individual Bits
Default:
$000000
I5050 controls which of the 24 potential data sources specified by I5001 to I5024 will be gathered when
data gathering is performed. It is a 24-bit value and each bit controls one potential data source. A 1 in the
I5050 bit enables the gathering of the data source; a 0 in the I5050 bit disables the gathering of the data
source.
