Software
6.2.6.2 Configuration with UDDC - Universal Device Description Composer
For quick configuration the esd software
UDDC
(“Universal Device Description Composer”) can be
used to generate a complete EtherCAT ESI file that already includes the variables. UDDC
additionally generates a C header file that might be helpful for the configuration of the UDP remote
station.
This minimizes the configuration effort at the EtherCAT side for the file import into the EtherCAT
configuration tool and, if applicable generating the CoE initializing commands for the CoE object
0x2030 – “UDP Gateway”.
INFORMATION
The esd software tool
UDDC
(“Universal Device Description Composer”) is included on
the enclosed ECX-EC-CD.
For further information read the UDDC Software Manual on the ECX-EC-CD.
UDP Gateway Quickstart with UDDC:
1. Start new UDDC project for “EtherCAT UDP Gateway”.
2. Create the respectively required
output
variables for both sides.
(Outputs are the variables that can be written.)
3. Copy the respective output variables to the respective input side
(e.g. by click to arrow between the sides).
4. Export device description.
→ Now a matching “.xml”-ESI file and a “.h” file are available
5. Import the .xml ESI file into the EtherCAT Master/-Configurator and write it in the ECX-EC
as EEPROM ESI (primary site).
6. In order to bring the ECX-EC to “operational” state, start the EtherCAT Master with the
ECX-EC.
→ Now the UDP-Gateway is active, transmits UDP frames and is ready to process
received UDP frames.
7. The “.h” file is ready for use with the Windows example UDP remote station – for other
systems a special UDP remote station has to be developed according to the protocol
description.
