Configuring An Ethercat Network; Ethercat Configuration Of The Gateway - How The Data Are Transferred - Leuze electronic MSI 400 Series Manual

You will find further information about how to configure the process diagram here:
• Configuration of gateways with MSI.designer [chapter 5]
• Software manual
Structure of the data block
The input data block consists of 50 bytes (byte 0 to 49) of data that is transferred from the EtherCAT net-
work to the MSI-FB-ETHERCAT gateway. The content of the data bytes does not meet the requirements of
a safety system. The values are only current as long as the gateway to the EtherCAT network is connected
and the gateway status is Operational. As soon as the state machine of the gateway adopts a state other
than Operational, this data is set to zero.

Configuring an EtherCAT network

A device description file (ESI = EtherCAT Slave Information) in XML format is delivered with the MSI-FB-
ETHERCAT. The EtherCAT master integrates this file into the EtherCAT system so that the master has the
necessary EtherCAT configuration data and can establish a connection to the gateway.
Please read the manual depending on your controller to see which steps are required in detail.

EtherCAT configuration of the gateway - how the data are transferred

The following steps are required to configure the communication between the PLC programming system
and the gateway. Configuration in the programming system is done by integrating a standardized ESI de-
scription file.
NOTICE
i
This documentation does not address the installation of the EtherCAT network or the other com-
ponents of the automation system project in the network configuration tool. It is assumed that
the EtherCAT project in the configuration program (e.g. Beckhoff TwinCAT) has already been
set up. The examples presented are based on configurations created with the help of Beckhoff
TwinCAT.
Step 1: Install the EtherCAT slave description file
Before the MSI-FB-ETHERCAT module can be used for the first time as part of the network configuration
tool (e.g. Beckhoff TwinCAT), the gateway description file must first be installed in the hardware catalog of
the tool.
