EK280
i
Whilst both of these parameters are available in two instances, they both contain the same value.
The last described parameter overwrites the parameter in the other instance.

8.2.5 Connection parameters

The connection parameters which shall be set for the respective applications will be explained in the
examples below:

8.2.6 Modbus master via the terminal device (RS232 directly, RTU or ASCII format)

8.2.6.1 Connection
The connection of the RS232 interface is described in  chapters
8.2.6.2 Parametrization of the EK280
n) Parameterization of the functions of the RS232 interface is described in  chapter 7.5.1.3.
a) Send the parameter file for Modbus parameterization
− Send the following parameter file to the EK280 ( chapter
EK280_xvx. – RS-232 & Modbus-Master RTU (via connection 8 & ext. power supply) (*)
o) The following Modbus parameters are preset in the file stated above:
− The first 24 tasks on the task list are processed.
− A task list is parameterized which writes several Modbus addresses from the standard Modbus table
( chapter 8.1.1) to the client.
− Telephone book entries are filled with dummy data.
− Link 8 is set up for Modbus master communications via the terminal device
− "Always" is proposed as the supply type (battery operation and external power supply)
− Reference is made to instance 7 of Modbus master information
