Module Configuration, Output, and Input Data
General Configuration Bits
These configuration bits apply to the 1769-HSC/B module and the CMX 5370
L2 packaged controller embedded HSC.
OCLO - Overcurrent Latch Off (OverCurrentLatchOff)
When set, this bit causes the module to make any overcurrent activity latch the
corresponding output off, simulating a physical fuse. When OCLO = 0, it
automatically resets. The rising edge of RBF resets the output.

(1) For the 1769-HSC/B module only. Bit 12 is Counter 0 reset disable; Bit 13, Counter 1 reset disable; Bit 14, Counter 2 reset disable; Bit 15, Counter 3 reset disable.
Counter reset function = 0: reset enable (default), 1: reset disable. The 1769-HSC/A module does not use bits 12…15 in the configuration array. See
page 73
for details.
IMPORTANT
Do not set this bit 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
for a list of prohibited settings.
