Format READ_GC_AI(GC_ID, N)
GC_ID: Analyzer ID (1 to 240)
N: AI number (1 to 16)
Return value: Integer
Return 0.0 to 1.0 in case of single precision real number.
Return –1.0 × 1038 in case of invalid (failed acquisition due to communication
failures, unregistered, etc.)
Explanation Omitted
READ_GC_DI Command
Function Acquires the DI ON/OFF specifi ed by the specifi ed analyzer ID.
Format READ_GC_DI (GC_ID, N)
GC_ID: Analyzer ID (1 to 240)
N: Dl number (1 to 32)
Return value: Integer
Return 1 for ON, 0 for OFF.
Return –1 in case of invalid (failed acquisition due to communication irregularities,
unregistered, etc.)
Explanation Omitted
READ_NV_DBL Command
Function Reads the data in double precision real number from the element number
specifi ed by the double precision real number-type nonvolatile memory.
Format READ_NV_DBL(N)
N: Element number to read out data (0 to 255)
Return value: Double precision real number type
Return double precision real number data read out from specifi ed address.
Explanation Omitted
READ_NV_INT Command
Function Reads data in integer from the element number specifi ed by the integer nonvolatile
memory.
Format READ_NV_INT(N)
N: Element number to read out data (0 to 1023)
Return value: Integer
Return integer data read out from specifi ed address.
Explanation Omitted
READ_NV_SNG Command
Function Reads the data in single precision real number from the element number specifi ed
by the single precision real number type nonvolatile memory.
Format READ_NV_SNG(N)
N: Element number to read data (0 to 511)
Return value: Single precision real number type
Return single precision real number-type data from specifi ed address.
Explanation Omitted
WAIT Command
Function Suspends script execution for N seconds.
Format WAIT(N)
N: WAIT time (1 to 864000, Unit: 0.1 sec)
WAIT time = in order to set to 1 second, set parameter to 10.
Return value: None
Explanation When the WAIT command is called in the script, it will remain in standby mode
until N elapses. After N elapses, the lines following the executed WAIT command
in the script will be executed.
