Universal Library Virtual Instruments (VIs) Counter VIs

C8536Cfg.VI

Configures an 8536 counter for desired operation. This VI can only be used with 8536 counters.

Summary:

Inputs: BoardNum [U32] - The board number assigned when installed with InstaCal. Can

be 0 to 100.

CounterNum [U32] - Counter number to configure

OutputControl [U32] - Specifies counter output signal used.

Recycle [TF] - Execute once or reload and re-execute until stopped.

Retrigger [TF] - Enable or disable retriggering.

Outputs:

ErrCode [I32] - Error code. See ErrMsg.VI

BoardNum [U32] - The board number assigned when installed with InstaCal. Can

be 0 to 100. Can be used to pass

BoardNum parameter to another VI.

Arguments:

BoardNum (input) The board number associated with a board when it was installed with InstaCal. The

specified board must have an 8536 counter

CounterNum Selects one of the counter channels. An 8536 has three counters. The value can be

1-n, where n is the number of 8536 counters on the board.

Refer to board-specific information contained in the Universal Library User's

Guide (available on our web site at www.mccdaq.com/PDFmanuals/sm-ul-user-

guide.pdf).

OutputControl Specifies one of the following the actions of the output signal.

HIGHPULSEONTC - Output will transition from low to high for one clock pulse on

terminal count.

TOGGLEONTC - Output will change state on terminal count.

HIGHUNTILTC - Output will transition to high at the start of counting then go low on

terminal count.

RecycleMode If set to RECYCLE (False, as opposed to ONETIME), the counter will automatically

reload to the starting count every time it reaches 0, then continue counting.

Retrigger If set to ENABLED (True), every trigger on the counter's trigger input will initiate

loading of the initial count. Counting will proceed from initial count.

BoardNum (output) The board number used when installed with InstaCal. This parameter can be used

to serialize VIs such that this VI precedes the next VI whose

BoardNum is attached

to this output.

ErrCode Error code returned from the Universal Library. Zero if no error occurred. Use the

ErrMsg VI to convert

ErrCode into a readable string.
