Omega Vehicle Security OMP-MODL manual Time Integration Function Icon, 11-61

11.. . APPENDIX A: MASTER ICON REFERENCE

TIME INTEGRATION FUNCTION ICON

FUNCTION:

Calculates the time integral of data type input over a User defined integration period. The Time Integral icon can only be used with DATA type inputs.

NOTE: For LOGIC type input time integration, refer to the Duty-Cycle icon.

For example, the Integral icon can be used in a Net (see above) to determine the hourly flow total of oil through a pipe. The oil flow RATE is sampled every minute by a 4-20mA flow transmitter and the signal is converted to GPM via a Math icon. This flow rate is then connected to the Integral icon which calculates the hourly volume flow by integrating the flow rate over time. The Sample Rate Clock connected to the Integral icon Update terminal determines the integration period.

INPUTS:

Data/Logic Signal: Data

Update Clock: Yes, specifies the time period over which the input signal is integrated

Enable:None

OUTPUTS:

Output Signal: Data type. The Integral icon updates its output with the new integral value after receiving an Update Command from the connected Update Clock.
