4.4 Fieldbus Interface
The fieldbus interface connects the Modul to EtherCAT.
It also enables access to the fieldbus specific Memory Register.
You can find the overview of the available Modbus registers in the
section "Overview of the Memory Register".

4.5 CDI - Configuration and Debug Interface
At the application interface, serial cables are available (RS232
interface with 3.3 V logic levels). You can connect these cables to a
terminal or PC with terminal simulation (e.g. PuTTY) using an
interface IC on the main board (see the application sample circuit
diagram, Appendix 2). You can read and change parameters using
structured menus. The CDI is also used for downloading scripts and
firmware updates.
The CDI is suitable for configuration during the development and for
diagnostic purposes. To configure several modules automatically, we
recommend performing the settings with "Modpoll". "Modpoll" is
freely-available software. You can find an introduction and example
of this in the Appendix Configuration via Modpoll [
}
134].
The serial interface is located at the application interface. The
respective cables are provided there with 3.3 V logic levels. To
connect these cables, you have the following options:
– Connect the cables directly with the UART inputs of the microprocessor
on the main board
– Convert the cables to standardised levels using level converters or
interface ICs. Afterwards, place the converted levels onto connectors for
connecting a PC or terminal.
We deliver the Modul to you with the following default settings to
enable access via the CDI :
• 115200 bit/s
• 8 data bits
• 1 stop bit
• Even parity (Even)
In section CDI Menus [

description of the menus for you.
