TypeResolver
The TypeResolver block is a polymorphic VI and supports the following operation modes to convert data types:
- To TC (for writing from LabVIEW™ to TwinCAT)
- From TC (for reading from TwinCAT to LabVIEW™)
To TC
The TypeResolver block in operation mode To TC initializes the TypeResolver, compares the LabVIEW™ data type with the TC3 data type, and converts the LabVIEW™ data to ADS raw data. The block then releases the TypeResolver from the memory.
Further information can be found in the section Resolving ADS data stream for TwinCAT 3.
Input/output | Meaning |
|---|---|
[0] Handle | Handle to the ADS client |
[5] SymbolName | ADS symbol consisting of AMSNetId and symbol name |
[9] WData | Raw data for ADS-Write |
[4] Handle | Handle to the ADS client |
[6] bHasMatched | Flag (TRUE if TwinCAT 3 and LabVIEW™ data type are identical, otherwise FALSE) |
[10] ADSWData | Type-resolved ADS write value |
From TC
The TypeResolver block in operation mode From TC initializes the TypeResolver, parses and converts the ADS data read by TwinCAT using ADS-Read into the LabVIEW™ data type Variant. The Type Release block releases the TypeResolver from memory.
Further information can be found in the section Resolving ADS data stream for TwinCAT 3.
