Curve Access - ABB RVT Serie Instrucciones De Instalación Y De Funcionamiento

It has the following prototype:
int CommandClient_ApplyParameterChanges();
6.2.4.4 CommandClient_ConvertRVTtoVB
This helper function allows retrieving a single parameter value from a parameter group.
It has the following prototype:
int CommandClient_ConvertRVTtoVB(unsigned char *ParamGroupValue,
The ParamGroupValue are the parameter group value as returned by the
CommandClient_GetParameter command. This is a buffer of unsigned char values.
The Offset and ValueType are specifying where to find the wanted data and what is the
type of the wanted value.
The OutputString and OutputStringSize are specifying where the string should be placed
and what its size is.
One should make sure that there's enough space in the output buffer for the string.
Currently, the biggest parameters defined for the RVT are 180 bytes big and are of the
string type. Numbers are converted into much smaller strings.
6.2.4.5 CommandClient_ConvertVBtoRVT
This helper function allows setting a single parameter value into a parameter group.
It has the following prototype:
int CommandClient_ConvertVBtoRVT(char
The InputString is the value to be converted and stored in the parameter group.
The ParamGroupValue is the parameter group value as returned by the
CommandClient_GetParameter command. This is a buffer of unsigned char values.
The Offset is specifying where to store the converted data and the ValueType is
specifying what type of data should be written to the parameter group.
One should make sure that the Offset and ValueType will not cause writing out of the
ParamGroupValue buffer.
