Interfaces
In DASYLab you also can request data over the DDE, TCP/IP, OPC, ODBC,
RS232 and IEEE interface from other programs or external devices.
Using Online DDE
You can exchange data with other programs that run parallel on the same
computer via the DDE interface (Dynamic Data Exchange). The modules for
these interfaces are on the Modules tab of the browser under Inputs/
Outputs»DDE. DASYLab can request data as a DDE client or, as a DDE
server, can provide data and execute commands.
If DASYLab acts as a DDE server, you must enter the address in the module:
•
Application: Name of the DDE server or of the executing program.
Enter
DASYLAB .
• Topic: Data area the client accesses. Enter SetData .
• Name: Module name of the DDE input module.
To establish the communication, the server must start first and then the client.
DASYLab transfers the data in ASCII format.
Exchanging Data over TCP/IP
TCP/IP stands for Transmission Control Protocol / Internet Protocol and is
the basis for the internet and also the intranet. The data source (server) can be
a DASYLab installation that provides data to a higher-ranking application
(client). The modules for these interfaces are on the Modules tab of the
browser under Inputs/Outputs»ICOM.
The Host IP address specifies the communication partner in the network. You
can enter the IP address as a number, such as
111.100.101.111 , or as the
name of the client such as the computer name or web address. The transport
protocol, such as
WWW , POP3 , or FTP , determines the port address. DASYLab
appends the value of the port address to the IP address with a colon. For
example, if you select
WWW , DASYLab displays the IP address as
111.100.101.111:80 .
