Gateway
For Connecting EnDat
Encoders to PROFINET IO
June 2016
PROFINET gateway
For connecting EnDat encoders
Encoders with EnDat interface for
connection via gateway
Absolute encoders from HEIDENHAIN
with EnDat interface are suitable for
PROFINET IO. The encoder is electrically
connected through a gateway. The complete
interface electronics are integrated in the
gateway, as well as a voltage converter for
supplying EnDat encoders with DC 5 V ±5 %.
This offers a number of benefits:
• Simple connection of the field bus
cables.
• Encoder dimensions remain small.
• No temperature restrictions for the
encoder. All temperature-sensitive
components are in the gateway.
• No bus interruption when an encoder
is exchanged.
Besides the EnDat encoder connector, the
gateway provides connections for PROFINET
and the power supply.
Since the gateway is a bus member, the
cable to the encoder is not a stub line,
although it can be up to 40 meters long.
PROFINET IO
PROFINET IO is the open Industrial Ethernet
Standard for industrial communication. It
builds on the field-proven function model
of PROFIBUS-DP, but uses fast Ethernet
technology as physical transmission
medium and is therefore tailored for fast
transmission of I/O data. It offers the
possibility of transmission for required
data, parameters and IT functions at the
same time.
Physical characteristics
HEIDENHAIN encoders and the gateway
are connected to PROFINET in accordance
with 100BASE-TX (IEEE 802.3 Clause 25)
via one shielded twisted pair of wires per
direction. The data transfer rate is 100 Mbit/s
(Fast Ethernet).
PROFINET profile
HEIDENHAIN encoders and gateways
fulfill the definitions as per Profile 3.162,
Version 4.1. The device profile describes
the encoder functions. Rotary encoders
support the functions of class 4 (full range
of scaling and preset functions). The
functions supported by the gateway vary
depending on the connected encoder.
More information about PROFINET can
be obtained from the PROFIBUS user
organization (PNO).
Commissioning
To put an encoder with PROFINET interface
into service, a general station description
(GSD or GSDML) file must be downloaded
and imported into the configuration
software. The GSD or GSDML contains the
execution parameters required for a
PROFINET IO device.
Encoders or gateway with PROFINET
Encoders with integrated PROFINET
interface or the gateway are directly
integrated in the network. Addresses are
distributed automatically over a protocol
integrated in PROFINET. A PROFINET-IO
field device is addressed within a network
through its physical device MAC address.
The encoders feature two double-color
LEDs for diagnostics of the bus and the
device.
