2-14 Module Operation
Rate Range
In a rate range, the outputs are active if the rate measurement is
within the user-defined range. The valid input rate is dependent upon
the operating class. In Class 1, the input rate can be up to 32,767 Hz in
either direction. In Class 4, the input rate can be up to 1 MHz in either
direction. The linear counter example in Figure 2.9 uses Class 1
operation.

Counter Input Data
The format of the counter input data table depends on the module’s
mode and class of operation. The status data formats for Class 1 and
Class 4 are shown below, followed by explanations of the
programming bits and status bytes. Mode 1 is the default for both
Class 1 and Class 4 operation.
