Input Function; Communication Function; Logging Function Of Measurement Data - Omron KM1 User Manual

Input function

The input functions include the following functions.
• Event input 7 points
PMU1A PMU2A
(Electric power) (Power two-system)
× ×
A pulse output from external equipment is counted as an input pulse.
Using the event input can achieve the 3-STATE function, whose target for judgment includes
the following: a power original unit calculated by dividing the total power consumption, which is
measured with PMU1A (electric power) and PMU2A (power two-system), by the total value of
two input count numbers (event inputs 1 and 2, event inputs 3 and 4, and event inputs 5 and 6),
a pulse input ON time measured by using OR judgment, and an event input.
The power original unit and the pulse input ON time are used for measurement of tact power in
a production line and for calculation of operating time of equipment, respectively.
* The 3-STATE function using power original unit and event input are available only when the
product is connected to PMU1A (electric power), PMU2A (power two-system).

Communication function

The communication function using CompoWay/F and Modbus (RTU) is available.

Logging function of measurement data

PMU1A PMU2A
(Electric power) (Power two-system)
Model KM1 has a data logging function. Log data is divided into the three types: data that is backed
up every 5 min, data that is backed up at arbitrary timing (5 min, 10 min, 30 min, 1 hour, 2 hours, 6
hours, 12 hours, or 24 hours), and alarm history that is backed up when an alarm is generated.
1) Data that is backed up every 5 min
This data includes the following items.
Total active power consumption, total regenerated energy, and total reactive power
3-STATE HIGH total power consumption, 3-STATE MIDDLE total power consumption,
3-STATE LOW total power consumption
3-STATE HIGH total time, 3-STATE MIDDLE total time, 3-STATE LOW total time
Pulse input ON time, pulse input count
2) Data that can be saved as log data at arbitrary timings
Log data is saved in conjunction with the time of the main body.
For the items, refer to "List of log data to be saved" on Page A-15.
3) Alarm history
Histories of alarms generated in the past can be confirmed via communication.
Data is saved every 5 min.
For details, refer to Page 3-12.
