2.4.2.1
Ethernet Connection
Please refer to 2.1 Device-specific Documentation to connect the Service Software over Ethernet. The
Device Address (Device to be addressed) can be found on the LTR-1200 Menu or on the Built-in web
site. It usually is the same as the Terminal Number. The LTR-1200 provides a total of six connections
(TCP/IP, Port 50000, Timeout: 10s) to control the LDD/TEC Drivers over Ethernet. For Third Party
Software communication please refer to the MeCom communication protocol specifications (See chapter
2.1 Device-specific Documentation).
2.4.3 Service Software Default Address
In some cases it may be helpful to configure a default LDD/TED driver as standard device. This can be
done by setting the 'Service Software Default Device' parameter to a specific LDD/TEC Device Address in
the Display menu. In this case the Device Address 0 will be routed to the 'Service Software Default
Device'.
2.4.4 Access over Third Party Software
For Third Party Software communication please refer to the MeCom communication protocol
specifications (See chapter 2.1 Device-specific Documentation).
2.4.5 Communication Fault Management
2.4.5.1
For RS485, RS232 and USB Interfaces
A received MeCom-Package with a wrong CRC is not being processed, no error is generated.
If a MeCom-Package is being forwarded to a device (LDD/TEC) and no answer is received from the
device, no error is generated. The sending host must repeat the MeCom-Package.
2.4.5.2
For Ethernet Interface
A received MeCom-Package with a wrong CRC results in closing the corresponding TCP connection.
If a MeCom-Package is being forwarded to a device (LDD/TEC) and no answer is received from the
device, the MeCom-Package is being sent to the device two more times. If still no answer is received, the
TCP connection is closed by the LTR-1200.
