Rockwell Automation 1747-PCINT API Software for 1746 I/O - Manual (Page 93)

OC_GetStatusFile Library of Routines 6–39
Publication 1747-6.5.3 June 1998
Return Value:
Considerations:
Supported in the DOS API library and the Windows NT API library
Example:
HANDLE Handle;
STSFILE stsfile;
int retcode;
retcode = OC_GetStatusFile( Handle, &stsfile );
17 dynamic configuration
DII preset
When this value is 0 or 1, an interrupt is generated each time the bit
transition comparison is satisfied (see words 15 and 16). When this value
is 2-65535, a count occurs each time the bit transition comparison is
satisfied. When the total number of counts equals the DII preset value, an
interrupt will be generated.
This word is applied upon detection of the DII reconfigure bit 11/10 and
at the end of each I/O scan.
18 status
DII accumulator
The DII accumulator contains the number of count transitions that have
occurred (see word 17). When a count occurs and the accumulator is
greater than or equal to the preset value, a DII interrupt is generated.
19 status
Scanner firmware series
This word indicates the scanner firmware series number. The series and
revision numbers are used to identify versions of firmware.
20 status
Scanner firmware revision
This word indicates the scanner firmware revision number. The series and
revision numbers are used to identify versions of firmware.
21 status
1746 I/O PCI Interface hardware series
This word indicates the 1746 I/O PCI Interface hardware series number.
The series and revision numbers are used to identify versions of firmware.
22 status
1746 I/O PCI Interface hardware revision
This word indicates the 1746 I/O PCI Interface hardware revision number.
The series and revision numbers are used to identify versions of firmware.
23 status
Scanner RAM size
This word indicates the size of RAM in 16-bit K words. For example, a
value of 64 indicates 64K words, or 128K bytes.
24 status
Scanner flash ROM size
This word indicates the size of flash ROM in 16-bit K words. For example,
a value of 64 indicates 64K words, or 128K bytes.
