8.1.2 Restrictions on CombinationsAvailable conditions vary by functions. Comparison of functionsItem Capture function Sampling capture functionUsable number of points Max. 2 points Max. 1 pointThe capture function cannot be used when using the sampling capture function.Used unit memory (UM)area (Note 1)Individually usable;Capture 0 register: 1 point (2 words)Capture 1 register: 1 point (2 words)Use Capture 0 register: 1 point (2words)Difference value register (Value of Capture 1 register - Value of Capture 0 register):1 point (2 words)Buffer function (Note 2)Data in the capture registers are shifted to the buffer area in sequence whenexecuting the capture function.For the capture 0 register, capture 1 register, difference value register (whenactivating the capture 0) and difference value register (when activating the capture1), each 60-point (120-word) area is secured.Capture function validcondition(Note 2)The capture function is valid while thecapture enable request signals (Y7, Y17,Y27, Y37) is on using user programs.The capture function is always valid.Capturetrigger(Note 1)Allocated in the configuration menu of tool software.Controlsignal 0Used as a trigger for capture 0 orcapture 1.Used as a tirgger for both capure 0and capture 1.Controlsignal 1Used as a trigger for capture 0 orcapture 1. Not usedCapturetriggersignal validconditionActivated when any of the followingconditions is met. Leading edge of control signal Trailing edge of control signalIt is possible to allocate one controlsignal to different capture numbers asthe signals of leading edge and trailingedge respectively.Activated when any of the followingconditions is met. Control signal (Positive logic) Control signal (Negative logic) Capture enable request by userprograms (Y7, Y17, Y27, Y37)Capture data memoryarea clear (Note 3)Capture 0 register and capture 1 register can be cleared individually using userprograms.Buffer areas can be reset at the same time.Capture done flag clear(Note 3)It is automatically cleared at the time of I/O refresh.Capture 0 register and capture 1 register can be cleared individually using userprograms.(Note 1) Functions and capture trigger signals to be used are set in the configuration menu of tool software or userprograms.(Note 2) The buffer function and capture function valid conditions are available from thei high-speed counter unitVer.1.2.(Note 3) The capture value clear request and capture done flag clear request signals are available from the high-speed counter unit Ver.1.2. They can be set in user programs.Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
