VT library version 1.4.9 or later is required for ISOBUS AUX-N support. See also ISOBUS_AUX_FunctionHandler (FB) and How to use AUX Functions
Supported platforms: CODESYS 2.3
This function block is the main block for the ISOBUS VT library. It is used to handle the connection and object pool download to the VT.
Library version 1.4.9 or later supports ISOBUS AUX-N Functions. Due to AUX-N support VT client needs to handle up to two VT client-server connections at same time.
If UI is connected to primary VT, then only primary VT connection is needed
If UI is connected to secondary VT, then two VT connections are used (AUX to primary, when AUX objects are used by object pool)
The AUX-N communication is handled automatically by library. See also How to use AUX Functions and ISOBUS_AUX_FunctionHandler (FB).
