AVReporter supports the following OPC data types for logging: - VT_I1 - VT_I2 - VT_I4 - VT_I8 - VT_UI1 - VT_UI2 - VT_UI4 - VT_UI8 - VT_INT - VT_UINT - VT_R4 - VT_R8 - VT_BOOL Every time we set up the tags in our OPC server, we have to make sure we use these data types. This list will give more details about the supported OPC datatypes: VT_I2: Context Description V, S, T Either the specified type, or the type of the element or contained field MUST be a 2-byte signed integer. VT_I4: Context Description V, S, T Either the specified type, or the type of the element or contained field MUST be a 4-byte signed integer. VT_R4: Context Description V, S, T Either the specified type, or the type of the element or contained field MUST be a 4-byte IEEE floating-point number. VT_R8: Context Description V, S, T Either the specified type, or the type of the element or contained field MUST be an 8-byte IEEE floating-point number VT_BOOL: Context Description V, S, T Either the specified type, or the type of the element or contained field MUST be VARIANT_BOOL (see section 2.2.27). VT_I1: Context Description V, S, T Either the specified type, or the type of the element or contained field MUST be a 1-byte integer. VT_UI1: Context Description V, S, T Either the specified type, or the type of the element or contained field MUST be a 1-byte unsigned integer. VT_UI2: Context Description V, S, T Either the specified type, or the type of the element or contained field MUST be a 2-byte unsigned integer. VT_UI4: Context Description V, S, T Either the specified type, or the type of the element or contained field MUST be a 4-byte unsigned integer. VT_I8: Context Description V, S, T Either the specified type, or the type of the element or contained field MUST be an 8-byte signed integer. VT_UI8: Context Description V, S, T Either the specified type, or the type of the element or contained field MUST be an 8-byte unsigned integer. VT_INT: Context Description V, S, T Either the specified type, or the type of the element or contained field MUST be a 4-byte signed integer. VT_UINT: Context Description V, S, T Either the specified type, or the type of the element or contained field MUST be a 4-byte unsigned integer.
