SAMPLE RATE CLOCK F UNCTION I CON
The Sample Rate Clock icon generates the Update signal/command used throughout
Nets to set Sampling Rates of the different input type icons. (The icon derives its clock
rate from a OMP-MODL internal clock.)
When the Sample Rate Clock generates an Update command, it causes the connected
icons to read their inputs, process the signal accordingly, then Update their Outputs.
Sample Rate Clocks within a Net set the pace at which the various branches of the
Program Net sequence.
Multiple Sample Rate Clocks can be used within a single Program Net to provide different
sampling rates.
INPUTS:
Alternate Rate Input: Logic type input. The Sample Rate Clock has a Logic
Input terminal that is used to control which of two clock rates will be output
(see Sample Rate Clock Configuration Dialog below) .
If the Alternate Rate Input is left unconnected, Update pulses will be output
at the standard rate. If connected to a Logic type (True/False) Output from
another icon (as shown in the Net below), the state of this signal will
determine which of two rates will be used. When the Input is LOW, the
Standard Update rate will be output. When the Input is TRUE (in the Net
below, when an overtemp condition occurs) , the Alternate faster Clock
Update rate will be output.
