Chapter 4 Module Configuration, Output, and Input Data
Inv - Range Invert (Range12To15[ n ].Invert)
Indicates the active portion of Range
n. When Range12To15[n].Invert = 0, the
outputs are activated when the range value is at or between the
Range12To15[
n].LowLimit and Range12To15[n].HiLimOrDirWr. When
Range12To15[ n].Invert = 1, the outputs are activated when the range is at or
outside the range limits.
Input Array The input array, which consists of 35 words, allows read-only access to the
module’s input data via word and bit access. The input array is described below.
The functions are described in more detail in the sections following the table.
Object Value (Current Count or Current Rate)
Low Limit High Limit or
Direct Write Value
INACTIVE ACTIVE INACTIVE
ACTIVE ACTIVE INACTIVE
Invert Bit = 0
Invert Bit = 1
IMPORTANT During the non-run states (program and fault), the module continues to
update the input array (continues counting). Depending on the bus
master, you may not see this.
TIP Status bits for a particular counter reflect the configuration settings for
that counter. To receive valid status, the counter must be enabled and the
module must have stored a valid configuration for that counter.
