F165_HighSpeedCounter_Cam
Cam control
Create your own DUT using the following DUT as a sample:
F165_HighSpeedCounter_Cam_8_Values_DUT
The following parameters can be specified in the DUT:
 Control code
 Word address for output relays
 Number of target values
 Target value 1
 ...
 Target value n
 Maximum target value

 Whenever the elapsed value is in the target value area n to n+1 (incremental
counting) or n+1 to n, (decremental counting), the corresponding output relay n is
TRUE.
 In the example above, maximum target value control has been enabled. When
the elapsed value reaches the maximum target value, the elapsed value is reset
to 0 and counting restarts.
 Specify the word address of the output relays in an overlapping DUT, e.g.
BOOL32_OVERLAPPING_DUT, and apply this DUT at dutBitOutputs.
Description
This instruction performs cam control according to the parameters in the specified DUT with a
maximum of 31 target values for the high-speed counter. An interrupt program can be executed
whenever the elapsed value matches one of the target values.
