Hi,
I think bit extension do not work with get/set val.
BLKSTA is a packed long so you will have to bit match it if you want the SE
parameter. If you are only interest in SE then you can use C:B.SE
The ACK parameter is not settable well the UNACK parameter is not settable.
The only way I know how to acknowledge an alarm is via the display manager
command almack C:B

Subject: [foxboro] C code for reading BLKSTA
I need to make a C program to get a value of the BLKSTA parameter. I have this
program from the Sun Compiler installation notes with the modifications
required to get the value of the BLKSTA.SE parameter:
#include <stdio.h>
#include <stdlib.h>
#include <fox/om_user.h>
#include <fox/om_ecode.h>
main()
{
unsigned int value; /* object value */
unsigned int status; /* object data type */
int data_len; /* data length */
getval ("COMPOUND:BLOCK.BLKSTA.SE", VARIABLE, 0, &value, &status,
&data_len);
printf ("The value is = %f\n", value); }
Is this code right?
Also I have to use the setval call to set the SUP_IN.ACK parameter. Does
anybody have some example to accomplish this?
Thanks!
