Counter Module
Output Array
The Output Array, which consists of 34 words, allows you to access
the module’s real-time output data to control the module. The
default value is all zeros.
IMPORTANT
The Output Array contains dynamic configuration
data. The settings in the Output Array must be
compatible with the settings in the Configuration
Array.
For example, do not attempt to set Counter Control
Bits for a given counter in the Output Array unless
NumberOfCounters in the Configuration Array
indicates that the counter is declared to be used.
IMPORTANT
All Not Used bits (shaded in the table below) must be
set to 0 or the InvalidOutput bit in the Input Array
will be set. When the InvalidOutput bit is set, the
entire Output Array is rejected until an Output Array
that does not have this error is sent.
