EtherCAT Gateway
Wieland Electric GmbH | BA000970 | 07/2019 [9855]
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). Wieland Electric 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
79543435
Available data
The samosPRO EtherCAT gateway can provide the following data:
• Process data
– Logic results from the samosPRO (see Routing Table [ch. 5.1.3, p. 43])
– Input values (HIGH/LOW) for all samosPRO input expansion modules in the system
– Output values (HIGH/LOW) for all samosPRO input/output expansion modules (see Module
state / input and output values [ch. 3.3.1, p. 24])
– Output data from another network, i.e. data received from a second gateway in the sa-
mosPRO system (see Transmission of data from a second network [ch. 3.3.3, p. 25])
• Diagnostics
– Test values (CRCs) (see Configuration test values (CRCs) [ch. 3.3.4, p. 25])
– Error and state information for all modules (see Error and state information for modules
[ch. 3.3.5, p. 26])
Data sets
The physical samosPRO modules are not presented as typical hardware modules in the network.
Instead, the data provided by the samosPRO system have been arranged in three input data sets.
