Example

void query_groups(CF_SERVER server)

{

char names[CF_MAX_GROUPS][CF_MAX_GROUP_NAME_LEN]; int starts[CF_MAX_GROUPS];

int sizes[CF_MAX_GROUPS];

cfGetGroups(server, names, starts, sizes);

}

cfGetInstIdentify

Syntax

int cfGetInstIdentify(CF_HANDLE server, char *idstring);

Description

This command returns a description of the instrument. The string begins with the model number, then the product name, followed by the firmware version number, followed by instrument option descriptions or abbreviations. The idstring is a maximum of CF_MAX_ID_LEN characters in length and is returned as a null-terminated C string.

cfGetInstStatus

Syntax

int cfGetInstStatus(CF_HANDLE server, int *status);

Description

Returns the instrument status. Individual bits within the status word are defined to indicate various status conditions. The following constants can be used to test different status conditions:

CF_EXT_FAULT_IN_STAT

An input configured to the CF_EXT_FAULT_IN function was

 

asserted since the last time cfProtectClear was called.

CF_EXT_INTERLOCK_STAT

An input which was configured to the CF_EXT_INTERLOCK

 

function is true

CF_SERIAL1_SWITCH_STAT

True when serial port 1 is set as the configuration terminal port

 

by a hardware switch

CF_LOW_RAIL_STAT

The rail voltage got too low since the last time cfProtectClear

 

was called.

CF_HIGH_RAIL_STAT

The rail voltage got too high since the last time cfProtectClear

 

was called.

CF_OVERTEMPERATURE_STAT

The internal temperature got too high since the last time

 

cfProtectClear was called.

CF_CALIBRATING_STAT

The instrument is calibrating

CF_POWER_ON_STAT

The instrument has not finished its power-on initialization

CF_POWER_FAIL_STAT

True whenever the CF_POWER_FAIL_IN signal is true.

CF_RAIL_NOT_READY_STAT

There is no dc voltage on the power bus

CF_RESTART_STAT

True whenever there is a saved shutdown state that can be

 

restarted with cfRestart().

CF_SELFTEST_STAT

True when a selftest is in progress

CF_SELFTEST_ERROR_STAT

True when a selftest is in progress

CF_SHUTDOWN_STAT

True when either an automatic power fail shutdown occurred or

 

cfShutdown() was called since the last time cfProtectClear() was

 

called.

CF_CAL_ERROR_STAT

True when a selftest is in progress
