1.4 Main features
●EtherNet/IP™ – interface with CIP Safety™ protocol, used to transfer a safe position and a safe
velocity
●Fast process data channel via EtherNet/IP™, non-safety-related
●Variant 1 only:
Additional incremental or SIN/COS or SSI interface, non-safety-related
●Two-channel scanning system, for generation of safe measured data through internal channel
comparison
– Variant 1:
Channel 1, Master system:
Optical single-turn scanning via code disc with transmitted light and magnetic multi-turn
scanning
Channel 2, Test system:
Magnetic single- and multi-turn scanning
– Variant 2:
Channel 1, Master system:
Magnetic single- and multi-turn scanning
Channel 2, Test system:
Magnetic single- and multi-turn scanning
●One common drive shaft
The untested Channel 1 Master System data and the Channel 2 Test System data are separately
provided in the non-safety-related process data channel with normal EtherNet/IP™ protocol and short
cycle time.
The inspection system is used for the internal safety check. “Safe data” obtained through two-channel
data comparison are packed into the CIP Safety™ protocol and transmitted to the controller via
EtherNet/IP™.
The optional incremental interface in Variant 1, or its alternative SIN/COS interface, are derived from
the master system and are not evaluated with respect to safety.
Instead of the incremental interface, a synchronous-serial absolute-value interface (SSI) is available,
which is also not evaluated with respect to safety.

1.5 Principle of the safety function
System safety is established as follows:
– Each of the two scanning channels is largely fail-safe thanks to individual diagnostic
measures.
– The measuring system internally compares the positions detected by both channels in two
channels and determines the velocity in two channels and transfers the safe data in the CIP
Safety™ protocol via EtherNet/IP™.
– In the event of a failed channel comparison or if another error is detected through the internal
diagnostic mechanisms, the measuring system switches the CIP Safety™ channel to error
status.
– Initialization of the measuring system and execution of the preset adjustment function are
appropriately safeguarded.
– The control additionally checks whether the obtained position data are within the position
window expected by the control. Unexpected position data are, e.g., position jumps, tracking
error deviations and incorrect direction of travel.
– In case errors are detected, the control introduces appropriate safety measures defined by the
system manufacturer
– The system manufacturer ensures, through correct attachment of the measuring system, that
the measuring system is always driven by the axis to be measured and is not overloaded.
– The system manufacturer performs a safeguarded test during commissioning and whenever a
parameter has been changed.

2.2 Safety-related requirements when using CIP Safety™ devices
●Exchanging the measuring system requires the backup device to be configured correctly and the
user to verify its correct function by a test run in safe mode before recommissioning the replaced
measuring system. See also Safety Manual TR-ECE-BA-GB-0142, Chapter 6 “Replacing the
measuring system”.
●The user must ensure the originator and measuring system are correctly configured when a safety
connection of the measuring system has been configured with a safety configuration ID
SCID = 0. However, we strongly advise against this operating mode, as it bypasses an
automated security check. See Chapter 4.5 from Page 36.
●Unique SNN numbers must be assigned for each safety network or safety subnet across the
entire system. See Chapter 3.5 on Page 29.
●The transmitted SCID and configuration data must be compared with the SCID and configuration
data originally displayed on the PC if the measuring system is configured using a PC
(workstation). See Chapter 4.5 from Page 36.
●The user must validate all downloads to the measuring system. See Chapter 4.5 from Page 36.
●A user test is required to ensure a signature is verified (and the configuration locked). See Chapter
4.5 from Page 36.
●Connection data and measuring system configuration data must be downloaded to the measuring
system first for an originator configuration to be tested and verified with such data. This is the only
way to confirm the measuring system SCID. See Chapter 4.5 from Page 36.
●The lock attribute can be set in the measuring system only after the user has verified the correct
function of the measuring system by a test run in safe mode. See Chapter 4.5 from Page 36.
●A configuration received by the measuring system from a Safety Network Configuration Tool
(SNCT) must afterwards be uploaded from the measuring system to the SNCT tool and be
compared. The lock attribute can only be set if the data match perfectly. See Chapter 4.5 from
Page 36.
●An existing configuration must be deleted before installing a measuring system in a safety
network. See Chapter 4 on Page 32.
●A measuring system must be programmed with the intended Target Unique Network Identifier
(TUNID) before it can be installed in a safety network. See Chapter 3.5 on Page 29.
●A safety function user must carefully consider the effects of mixing different SIL level devices in
the network. See Chapter 9.1.26 on Page 71.
●Safety connection configurations must be verified after they have been applied in an originator to
confirm that a target connection is working as intended. See Chapter 8 from Page 49.

●The measuring system status LEDs are not reliable indicators and no guarantee can be given that
they will provide accurate information. LEDs may thus only be used for the purpose of general
diagnosis during commissioning or troubleshooting but may not be used as an operational display.
See Chapter 4.3 on Page 34.
●The automatic SNN setting function of originator devices may only be used if the safety system
does not rely on it. See Chapter 3.5.2 on Page 30.
●The measuring system must always be locked after the configuration data have been verified. See
Chapter 4.5 from Page 36.
●As part of the final verification process, users must verify that the measuring system has received
its ownership assignment from the relevant originator if the measurement system has been
configured via a Type 1 SafetyOpen.
●Visually verify that all configuration data have been correctly downloaded to the measuring
system. See Chapter 4.5 from Page 36.
The measuring system cannot receive configuration data
from another originator in
the presence of an ownership assignment by another originator. In this case you
must reset the measuring system to remove the ownership assignment. See Chapter
“Resetting the safety-related device parameters“ on Page 39.

2.3 Safety functions of the fail-safe processing unit
The originator connected to the measuring system must perform the safety checks listed below.
To ensure the appropriate measures can be taken in the event of an error, the
following applies:
1.
The CIP Safety™ data channel is automatically put into the fail-safe state if
the measuring system detects an error and a safe position cannot be
output. In this state, so-
called “passivated data” are output via
CIP Safety™.
Passivated data as seen by the measuring system:
CIP Safety™ data channel: all outputs are set to 0
CIP Safety™ Device Status: in ABORT state
CIP Mode Byte: Run/Idle-Bit is set to Idle
CIP Safety™ CRC: valid
TR Safety status: Safe State-Bit 24= 0
Upon receipt of passivated data, the Originator must put the system
into a safe state. The error state can be terminated only by eliminating
the error and exiting the ABORT state!
2.
The CIP Safety stack is stopped if a safe position cannot be output due to
a critical error (memory error) recognized by the measuring system. This
state doesn’t permit any safety-
related communication; a connection
timeout error is output.
Again, the Originator must put the system into a safe state if this
occurs. To exist this error state, try switching the supply voltage off
and then on again. The measuring system must be replaced if this
doesn’t work.
This does not necessarily affect the process data channel that can be addressed via
EtherNet/IP™. The process data continue to be output if an internal non-safety-
related channel diagnosis does not detect an error. However, these data are not
safe in terms of a safety standard.

3 Installation / Preparation for Commissioning
3.1 Basic rules
The safety function may be deactivated by wire-
based disturbance
sources!
All CIP Safety™ devices used on the bus must be EtherNet/IP™ and
CIP Safety™ certified.

All safety devices must also have a certificate from a “Notified Body”
(e.g., TÜV, BIA, HSE, INRS, UL, etc.).

The 24 V power supplies used must comply with the requirements of
IEC 60364-4-
41 SELV/PELV and be NEC Class 2 compliant for UL
applications.

The shielding effect of cables must also be ensured after installation
(bending radii/tensile strength!) and after connector changes. In cases
of doubt, use more flexible cables with a high
er current carrying
capacity.

Only use M12 connectors for connecting the measuring system, which
ensure good contact between the cable shield and the connector
housing. Connect the cable shield to the connector housing over a
large area.
Compensating curre
nts caused by differences in potential across the
shield to the measuring system must be prevented.

A shielded and stranded data cable must be used to ensure high
electromagnetic interference stability of the system. The shield should
be connected to protective ground in a well-
conducting manner using
large-
scale shield clips, if possible on either end. The shielding should
be grounded in the switch cabinet on one end only if the machine
ground is heavily contaminated with interference towards the switch
cabinet ground.

Equipotential bonding measures must be provided for the complete
processing chain of the system.

Power and signal cables must be laid separately. During installation,
observe the applicable national safety and installation regulations for
data and power cables.

Observe the manufacturer's instructions for the installation of
converters and for shielding power cables between frequency
converter and motor.
Ensure adequate dimensioning of the energy supply.

Upon completion of installation, a visual inspection with report should be carried out. Verify the
network quality with a suitable bus analysis tool whenever possible.
To ensure safe and fault-free operation, do observe
- the ODVA directive “Media Planning and Installation Manual” (Pub 148)
- the ODVA directive “EtherNet/IP™ Network Infrastructure Guide” (Pub 35)
- and the publications referenced therein!
In particular, do observe the EMC directive 2014/30/EU as amended!

3.2 EtherNet/IP™ transmission technology, cable specification
EtherNet/IP™ networks generally use an active star topology where a point-to-point connection links
the devices to a switch. One star topology advantage is that star topology supports devices with a
transmission rate of 10 Mbit/s as well as 100 Mbit/s. Devices using either of the two transmission rates
can also be combined, as most Ethernet switches automatically negotiate the transmission rate.
The measuring system also supports the Line (daisy chain) and Ring (DLR, optional) topologies.
Use category STP CAT5e patch cables (2 x 2 copper wire cables twisted in pairs and shielded) for
transmissions using the 100Base-TX Fast Ethernet standard. The cables are designed for bit rates of
up to 100 Mbit/s. The transmission velocity is automatically detected by the measuring system. The
shield needs to be earthed on one side only.
Transmit in full duplex mode. We recommend using switches with the following properties when
setting up the EtherNet/IP™ network:
•for the I/O communication:
- full duplex capability, on all ports
- IGMP snooping – restricts multicast data traffic to ports with an associated IP multicast group.
- IGMP Query – Routers (or switches) with active IGMP function periodically send queries to
find out which IP multicast group members are connected in the LAN.
- Port Mirroring – allows data traffic on one port to be mirrored to another port, important for
troubleshooting.
•other switch functions:
- e.g. redundant power supply
- Remote diagnostic capabilities
The EtherNet/IP™ Node ID can be set either via two rotary switches, flash configuration or DHCP.
The cable length between two nodes may be max. 100 m.
