GpibSetPPoll

Function

Sets response line of parallel poll of partner apparatus.

Format

Ret = GpibSetPPoll ( Id, AddrArray, DataLineArray, PolarityArray )

Parameter

Id [ VB.NET: Short ][ C, C++: short ][ C#: short ]

Specifies DevID or EqpID.

Whichever it specifies, operation does not change.

AddrArray [ VB.NET: Short() ][ C, C++: short * ][ C#: short[] ]

Sets addresses of slave devices to be Parallel Polled by array. (the Max. of device is 31)

0 to 30	Address of slave device
-1	Must be used at last of array

iPerforms OR operation of the value from 96 to 126(60H to 7EH ) and high-order bits of primary address when secondary address is being usedj

DataLineArray [ VB.NET: Short() ][ C, C++: short * ][ C#: short[] ]

Sets DIO response line of corresponding device.

Up to 8 devices can be identified at same time because that DIO line is 8-bit width.

furthermore, more than 8 devices can be identified as multi-devices are allotted on same bit.

1 to 8	DIO line number
-1	Must be used at last of array

PolarityArray [ VB.NET: Short() ][ C, C++: short * ][ C#: short[] ]

Retrieves corresponding polarity of the device.

0	Out of phase
1	Inphase
-1	Must be used at last of array

Return Value

Ret [ VB.NET: Integer ][ C, C++: long ][ C#: int ]

0	Normality completion
10001	Invalid ID was specified
10002	Driver can not be called
12252	The element of AddrArray is being set out of range, or the number of elements are more than 32
12253	The element of DataLineArray is being set out of range
12254	The element of PolarityArray is being set out of range
12262	Pointer to AddrArray is NULL
12263	Pointer to DataLineArray is NULL
12264	Pointer to PolarityArray is NULL
22273	When device is used as slave (non-controller), functions for master (controller) are execute
22293	The number of AddrArray is different from other array

Initial Value

AddrArray	-1	Not being set
DataLineArray	-1	Not being set
PolarityArray	-1	Not being set

Remarks

Example

Performs following settings. The device with primary address 1 responds on DIO line 1 in phase, the device with primary address 2 responds on DIO line 2 inphase, the device with primary address 3 responds on DIO line 3 out of phase, and the device with primary address 4 responds on DIO line 4 out of phase.
