CHAPTER 3: USING THE SNAP ETHERNET I/O DRIVER TOOLKIT SetDigPtCounterState V [in] long nPoint [in] long nState Return values are shown on page 61. Digital Bank Methods Use the following methods to read and write information in the digital bank area of the IEEE 1394-based protocol. For more information, see “Mask Data” on page 41, “Digital Bank Read—Read Only” on page 119, and “Digital Bank Write—Read/Write” on page 120. 66 SNAP Ethernet-Based I/O Units Protocols and Programming Guide Sets the specified digital point's counter state. v The OptoSnapIoMemMapX ActiveX component has a variant-only version of this method.

Retrieves the on-latch state of the entire digital bank as a mask. Retrieves the off-latch state of the entire digital bank as a mask. Retrieves the active counter state of the entire digital bank as a mask. Retrieves the point state, on-latch state, off-latch state, and active counter state of the entire digital bank. Uses a structure to retrieve the point state, on-latch state, off-latch state, and active counter state of the entire digital bank. V The OptoSnapIoMemMapX ActiveX component has a variant-only version of this method.

Analog Point Methods CHAPTER 3: USING THE SNAP ETHERNET I/O DRIVER TOOLKIT Write Methods Description SetDigBankDeactCounterMask V [in] long nPts63to32 [in] long nPts31to0 Uses the bitmask to turn digital points on. Uses the bitmask to turn digital points off. Sets the state of the digital bank from the nPts63to32 and nPts31to0 parameters. Only those points set in the nMask63to32 and nMask31to0 parameters are affected. Uses the bitmask to activate counters. Uses the bitmask to deactivate counters. v The OptoSnapIoMemMapX ActiveX component has a variant-only version of this method. Use the following methods to read and write information about individual analog points. For more information on analog point features, see page 20, “Analog Point Read—Read Only” on page 123, “Analog Point Write—Read/Write” on page 124, “Analog Point Calculation and Set—Read Only” on page 131, and “Analog Read and Clear/Restart—Read Only” on page 133. GetAnaPtValue V [in] long nPoint [out] float pfValue GetAnaPtCounts V [in] long nPoint [out] float pfValue GetAnaPtMinValue V [in] long nPoint [out] float pfValue GetAnaPtMaxValue V [in] long nPoint [out] float pfValue GetAnaPtTpoPeriod [in] long nPoint [out] float pfValue Read Methods Description Retrieves the value of the specified analog point. Retrieves the counts of the specified analog point. Retrieves the minimum value of the specified point. Retrieves the maximum value of the specified point. Retrieves the TPO period for the specified point. See the SetAnaPtTpoPeriod() method below for more information. SNAP Ethernet-Based I/O Units Protocols and Programming Guide 67
