sNetID                      : Is a string containing the AMS network identifier of the target device to which the ADS command is directed.

hDBID                       : Is the ID of the database to be used.

hAdsID                     : This is the ID of the ADS device to be used.

sVarName              : Provides the name of the variable.

nIGroup                   : Index group of the variable (optional, only on the BC9000).

nIOffset                   : Index offset of the variable (optional, only on the BC9000).

nVarSize                 : Size of the variable in bytes (optional, only on the BC9000).

sVarType                : Data type of the variable (optional, only on the BC9000).

Possible variable data types:     "BOOL" / "LREAL" / "REAL" / "INT16" / "DINT" / "USINT" / "BYTE" / "UDINT" / "DWORD" / "UINT16" / "WORD" / "SINT"

sDBVarName         : Variable name to be used in the database.

eDBWriteMode      : Determines if the new records will be added or if the existing records will be updated.

tRingBufferTime    : Contains the maximum age of datasets in a table. (only at Ringbuffer_WriteMode)

nRingBufferCount : Contains the maximum count of datasets in a table. (only at Ringbuffer_WriteMode)

bExecute                 : The command is executed with the rising edge.

tTimeout;                 : States the time before the function is cancelled.

END_VAR

bBusy          : The command is in the process of being transmitted by ADS. No new command will be accepted as long as "bBusy" remains TRUE.

bError          : Becomes TRUE, as soon as an error occurs.

nErrID          : Supplies the ADS Error Code or the TcDatabaseSrv_Error_Codes when the bError output is set.

sSQLState : Supplies the SQL error code of the specified database type.
