Counter Mode

–

Applies to WBK17 Only

WaveView supports several counter modes and can receive input

from up to two encoders (in 1X, 2X, or 4X modes).

All WBK17 modes are detailed in the WBK17 Document Module.

Note

The Encoder Mode can only be selected on WBK17

channels x-1 and x-5. Inputs “B” and “Z” must be

connected to the next consecutive channels.

Counter Mode Pull-Down List

Reference Note:

Refer to the WBK17 Document Module (in the WBK

Option Cards and Modules User’s Manual,

p/n 489-0902) for additional information regarding the

following counter modes.

•

Counter

The counter makes use of a 16-bit counter (Counter Low), or a 32-bit counter (Counter High). While

in this mode, the channel’s input increments the counter. The counter is cleared at the beginning of

each scan, and the value [just prior to clearing] is latched and returned to the WaveBook/516, /512A,

or WaveBook/516A. See the upcoming Programmer Note.

•

Totalize

The totalize mode makes use of a 16-bit counter (Counter Low), or a 32-bit counter (Counter High).

While in this mode, the channel’s input increments the counter and rolls it over, resulting in a

cumulative total for the counter value. (see the following Programmer Note)

Programmer Note:

In regard to programming, the “Counter Mode” involves selecting the “Clear on Read” option

within a single “Counter/Totalize Mode;” and the “Totalize Mode” involves selecting the

“Totalize” option. In WaveView, the Counter and Totalize modes are treated as two distinct

modes.

Note that the “

Clear on Read

” mode is not available when using an external clock.
