Data Transferred Into The Network; Data Set 1 - Leuze electronic MSI 400 Series Manual

Important information
• Use of hubs:
Hubs are not permitted in EtherCAT networks.
• Use of switches:
Switches in EtherCAT networks are only permitted between EtherCAT master and the first EtherCAT
slave (100 Mbit/s, full duplex). Leuze electronic GmbH offers its own switches under the product family
name "Ethernet Switch".
• Terminator:
If the gateway is the last device, the EtherCAT topology does not require a terminator.
• Recommendation
Take appropriate measures to protect the data cables and connectors against high mechanical load.
We recommend a fixed installation in conjunction with tension relief.

Data transferred into the network

Available data
The MSI 400 EtherCAT gateway can provide the following data:
• Operating data
• Logic results from the MSI 400 (see Routing Table [chapter 5.1.3])
• Input values (HIGH/LOW) for all MSI 400 input expansion modules in the system
• Output values (HIGH/LOW) for all MSI 400 input/output expansion modules (see Module state / in-
put and output values [chapter 3.3.1])
• Output data from another network, i.e. data received from a second gateway in the MSI 400 sys-
tem (see Transmission of data from a second network [chapter 3.3.3])
• Diagnostics
• Test values (CRCs) (see Configuration test values (CRCs) [chapter 3.3.4])
• Error and state information for all modules (see Error and state information for modules [chapter
3.3.5])
Data sets
The physical MSI 400 modules are not presented as typical hardware modules in the network. Instead, the
data provided by the MSI 400 system have been arranged in three input data sets.

11.5.1 Data set 1

Data set 1 (50 bytes) contains the process data. It can be compiled with the aid of MSI.designer. In the
form in which it is delivered, the content of data set 1 is preconfigured; it can be freely modified.
Note: Not allocated means that the byte value is equal to 0x00. However, the user can freely assign these
bytes.
