devices and Modbus/TCP Client.
The SDD ES ETH sends telegrams to the connected safety devices via a ring protocol.
The following types of data are transferred to the fieldbus and read in.
}Process data
– Information and commands on safety functions (OSSD, guard locking, …)
}Device data
– Material number, serial number, product version, actuator ID, …

SDD ES ETH

1003824-EN-06 | 12
}Configuration data
– Behaviour of the control of safety devices with guard locking (control of the guard
locking via SDD can be switched on and off on PROFINET, EtherNET/IP and ETH
using Autoinit)
Communication with connected control systems or control elements is via the bus interface
Modbus/TCP.
The IP address is set on the display with the multifunction switch.
Data structure
The input and output data is divided into the following data areas:
}Data for the overall system and for the SDD ES ETH
}Data for the connected safety devices
}List of specified changes of state and events
}Control system telegrams for the safety devices and responses from the safety devices
The data structure, including a list of the possible events, is described in detail in the Sys-
tem Description "Safety Device Diagnostics".

before touching the product, e.g. by touching an earthed, conductive sur-
face or by wearing an earthed armband.
Commissioning
General wiring guidelines
Please note:
}Information given in the Technical details [ 32] must be followed.
}Use copper wiring with a temperature stability of 75 °C.
}External measures must be used to connect the terminal to the functional earth.
}The device must be supplied from the same power supply as the connected safety
devices.
}The power supply must meet the regulations for extra low voltages with protective elec-
trical separation (SELV, PELV).
Ethernet interfaces
RJ45 interfaces ("Ethernet")
Two free switch ports are provided as Ethernet interfaces via an internal autosensing
switch. The autosensing switch automatically detects whether data transfer is occurring at
10 Mbit/s or 100 Mbit/s.
INFORMATION
The connected subscribers must support the autosensing/autonegotiation
function. If not, the communication partner must be set permanently to "10
Mbit/s, half duplex".

SDD ES ETH
Operating Manual SDD ES ETH
1003824-EN-06 | 14
The switch's automatic crossover function means there is no need to distinguish on the
connection cable between patch cable (uncrossed data line connection) and crossover
cable (crossover data line connection). The switch automatically creates the correct data
line connection internally. Patch cable can therefore be used as the connection cable for
end devices as well as cascading.
Both Ethernet interfaces use RJ45 technology.
Requirements of the connection cable and connector
The following minimum requirements must be met:
}Ethernet standards (min. Category 5) 10BaseT or 100BaseTX
}Double-shielded twisted pair cable for industrial Ethernet use
}Shielded RJ45 connectors (industrial connectors)

NOTICE
With the plug-in connection please note that the data cable and connector
have a limited mechanical load capacity. Appropriate design measures
should be used to ensure that the plug-in connection is insensitive to in-
creased mechanical stress (e.g. through shock, vibration). Such measures
include fixed routing with strain relief, for example.
Process data exchange
The RJ45 interfaces on the internal autosensing switch enable process data to be ex-
changed with other Ethernet subscribers within a network.
The product SDD ES ETH can also be connected to Ethernet via a hub (hub or switch).
