_7256_DO_Read_Back

Reads data back from digital output port control for all relay
SET or RESET status.

Syntax

U16 _7256_DO_Read_Back (U16 boardID, U16
*doReadBackData)

Argument

boardID

 : Board ID to the specific board.

diReadBackData

 : value read back from digital output ports,

with 0 indicating RESET condition and 1 SET.

Return Code

ERR_NoError
ERR_BoardNoInit

_7256_GET_IRQ_Status

Acquires current interrupt status.

Syntax

U16 _7256_GET_IRQ_Status (U16 boardID, U16
*COS_Status, U16 *CH0_Status, U16 *CH1_Status)

Argument

boardID

 : Board ID to the specific board.

COS_Status

: COS interrupt status, where 1 indicates inter-

rupt assertion, and 0 interrupt de-assertion

CH0_Status

: Digital input channel 0 interrupt status, where

1 indicates interrupt assertion, and 0 interrupt de-assertion

CH1_Status

: Digital input channel 1 interrupt status, where

1 indicates interrupt assertion, and 0 interrupt de-assertion.

Return Code

ERR_NoError
