Chapter 4 Module Configuration, Output, and Input Data

Inv - Range Invert (Range12To15[n].Invert)

Indicates the active portion of Rangen. 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 ACTIVEINACTIVE

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.
