SAMPLE RATE CLOCK FUNCTION ICON
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
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.
