ADAC Set 5600 Port Struct
This VI sets the digital I/O port settings for the 5600 Series cards. Refer to the 5600
manual for detailed information on each setting. This VI is only used with ADAC 5600
boards.
Device Handle (0) Device Handle is a numeric value that is used to identify the device
subsystem. The default Device Handle is 0.
5600 PORT STRUCT
Port Resolution Port Resolution is a numeric value that represents the desired
number of DIO port bits, either 8 or 16. The DIO ports DIN0 can be either 8 or
16 bit ports and DIN1 can only be an 8 bit port. When DIN0 is set for 16 bit
resolution DIN1 is not available. The DIO ports DOT0 and DOT2 can be either
8 or 16 bit ports and DOT1 and DOT3 can only be an 8 bit port. When DOT0 or
DOT2 is set for 16 bit resolution DOT1 or DOT 3 is not available respectively.
Port Mask Port Mask is a binary value that indicates which bits are to be read
during interrupt transfers. If the associated bit in the Port Mask control is set
="1" the bit is read, unactive bits will return "0".
A5600PORT
Debounce Debounce is a numeric value that indicates if the device's
debounce circuitry is enabled or disabled. When Enabled the Time
Constant value sets the time required for a stable input.
0:DISABLED
1:ENABLED
The default value is 1:ENABLED
Port Mode Specification Port Mode Specification defines the pattern
match condition.
0:DISABLED Pattern match is disabled.
