Publication 1746-UM006B-EN-P - August 2005
Module Overview 1-3
Operating Modes The module operates in 3 modes:
•
Range mode
•
Rate mode
•
Sequencer mode
Specific operating mode information is contained in Chapter 2,
Module Operation. The following information summarizes the
module’s operating modes.
Range Mode
In the Range Mode, you define a group of count ranges and define
the outputs to be active when the Accumulated Count value is within
each range. In this mode, the module offers:
•
up to 12 ranges
•
dynamically configurable ranges
•
ring or linear counter operation
•
input rate calculation
•
direct SLC processor control of unused outputs
Rate Mode
In the Rate Mode, you define a group of rate ranges and
corresponding outputs. When the Rate Measurement is within each
defined range, the corresponding outputs are active. In this mode, the
module offers:
•
Rate Periods from 10 ms to 2.55 seconds
•
input rates up to 32,767 Hz in either direction
•
up to 12 ranges
•
ring or linear counter operation
•
dynamically configurable Rate Period and range values
IMPORTANT
Appendixes D and E contain blank worksheets to
assist you when configuring your module. Appendix
D contains worksheets for Range and Rate Mode
operation. Appendix E contains worksheets for the
Sequencer Mode operation.
