PFE - Program to Fault Enable (ProgToFaultEn)
This bit indicates what should happen when the bus controller indicates a change
from one condition (Program mode) to another (Fault mode). If this bit is set (1),
the safe state operation of all four real outputs changes to that identified by the
Fault State and Fault Value words. If this bit is reset (0), the module continues
with the operation identified by the Program State and Program Value words.
Number of Counters (NumberOfCounters)
This 2-bit value indicates whether the module uses 1 counter, 2 counters,
3 counters, or 4 counters. The default value is 1 (2 counters).
Filter Selection
This value indicates the nominal filter frequency as shown in the table.
Bit 01 Bit 00 Counters
0 0 1
0 1 2
1 0 3
1 1 4
IMPORTANT Do not set this value while a counter or range is enabled (Ctr0En, Ctr1En,
Ctr2En, Ctr3En, or RangeEn set to 1). Attempting to do so will result in a
BadModConfigUpdate error.
See page 120 for a list of prohibited settings.
