ADS-Write
The ADS-Write block is a polymorphic VI and supports the following ADS communication modes to write data to TwinCAT:
For ADS-Write only one parameter is relevant, which can be set in the Symbol Interface and that is the parameter Timeout.
Sync Single
In this operation mode, the ADS client in LabVIEW™ sends a write request with the type-resolved ADS value to the ADS server in TwinCAT and waits for a response as to whether the value has been written.
