5.5 Hints regarding TcVirtualComDriver
In case the EL60xx is to cooperate with the TwinCAT Virtual Serial COM Driver, here are a few hints:
Usually the customer-specific higher-level Windows application sets the desired feature of the COM interface
according to the application, e.g. 2400 baud and 7N2 coding. Therefore, the customer-specific entries made
before parameterization in the CoE StartUp entries, the Settings dialogue, the VirtualComPort or the device
CoE are usually irrelevant.
Fig.147: Each higher level (if available or activated) dictates the communication features to the level below
it.
NOTE
TcVirtualComDriver version
Check whether the desired Baud rate/coding combination of the TcVirtualComDriver version and EL/EP ter-
minal used by you is also supported. If this is not the case:
●it may not be possible to open the COM port
●an ADS error message may appear in the ADS logger in the System Manager
●a CoE error message may appear in the ADS logger
The TcVirtualComDriver supports ExplicitBaudrate (CoE 0x80n0:1B) from version 1.18.
If the COM application has then set the features (such as baud rate) during the runtime, the correct setting
can be checked against it in the Online CoE, see fig.
