The following standard DAQBIOS commands are accessible on the diagnostics
port whenever one or more I/O boards are in operating mode:
DQCMD_ECHO // echo
DQCMD_RDCFG // read configuration (new)
DQCMD_RDSTS // read status
DQCMD_WRCHNL (selected)//write channel
DQCMD_RDCHNL (selected)// read channel
DQCMD_IOCTL (selected) // ioctl() - low priority command
DQCMD_SETLOCK // set/release port lock
Commands that are capable of changing the state of the running I/O boards will
not execute.
To switch a port into diagnostics mode, use the DqCmdSetLock API, as
described below:
int DAQLIB DqCmdSetLock(int Iom, uint8 Mode,char Password,uint32 *IP)
Parameters:
int Iom // Pointer to the DQIOME structure
uint8 Mode // Function mode (lock/unlock/check/diagnostics)
char *Password // password string; ignored (and can be NULL)
// if Mode is DQSETLOCK_CHECK
uint32 *IP // returns the IP address of the locking host
// if Mode is DQSETLOCK_CHECK
<Mode> can be one of the following:
#define DQSETLOCK_LOCK0 // Lock IOM to host
#define DQSETLOCK_UNLOCK1 // Unlock IOM
#define DQSETLOCK_CHECK2 // Get locking host IP
#define DQSETLOCK_DIAG4 // Switch to diagnostics
To advance a port into diagnostics mode, call this function with the <Mode>
parameter set to DQSETLOCK_DIAG. To return a port to normal mode, use the
same function call with DQSETLOCK_UNLOCK.
The following table describes the possible states of both ports:
DQCMD_ECHO
This command returns information about the board(s) installed. Use of this
command is described in the PowerDNA API Reference Manual.
