3 System overview
The UR67-IO-Link modules are IO-Link master modules that
are based on PROFINET. The metal housing (zinc diecast,
completely encapsulated) ensures that they conform to the
IP67 protection class. The UR67-IO-Link modules come in
two designs:
–UR67-PN-HP-8IOL-12-30M: 30-mm width, 8I/O ports
–UR67-PN-HP-8IOL-12-60M: 60-mm width, 8I/O ports
The UR67-IO-Link modules support the IO-Link standard
V1.1. The output current is a maximum of 2A per port. Four
ports have output circuits that are electrically isolated from
the rest of the network and from the sensor electronics.
The modules support a fail-safe function, which can be used
to set how a channel congured as an output is to respond
to an impaired or interrupted PROFINET communication.
All of the module interfaces are equipped with protection
against inverse polarity, short circuits and overloads.
3.1 Port characteristics
All ports are colour-coded and therefore cannot be mixed up:
–PROFINET network (green): D-coded, 4-pole M12 plug-in
connector (IN and OUT). The maximum transmission rate
is 100Mbps.
–I/O ports (black): 8 A-coded, 5-pole M12 plug-in connec-
tors
–Power supply connections (grey): L-coded, 5-pole M12
connector (IN and OUT).
Characteristics of the I/O ports
Each module features 8I/O ports:
–4type-A ports (IO-Link specification classA) with an addi-
tional, hard-wired digital input at pin2.
–4type-B ports (IO-Link specification classB) with different
designs depending on the type of module:
–UR67-PN-HP-8IOL-12-30M:
with an electrically isolated auxiliary power supply con-
nected to pins 2 and 5, respectively, and a total current
of 4A
–UR67-PN-HP-8IOL-12-60M:
with an electrically isolated auxiliary power supply con-
nected to pins 2 and 5, respectively, each with a max.
current of 2A (8A total current). The auxiliary power
supply can be congured as a digital output.
LED
Each I/O port is assigned two status LEDs which change co-
lour and the frequency at which they ash according to the
status of the respective port (seechapter 12).
3.2 Fieldbus characteristics
PROFINET product characteristics
The UR67-IO-Link modules support PROFINET IO device IRT
(Isochronous Real-Time). This allows time-critical process
data to be transmitted between the network components
in real time. The modules conform to the PROFINET speci-
cation V2.3 as well as to the requirements of Conformance
ClassC (CC-C).
The integrated Ethernet switch with two PROFINET ports al-
lows for the PROFINET network to be set up in a line or ring
topology A highly available network infrastructure can be set
up by also implementing the Media Redundancy Protocol
(MRP).
Supported protocols
The UR67-IO-Link modules use the following protocols:
– DCP: for the automatic allocation of IP addresses
– LLDP: for device detection in the immediate surroundings
(neighbourhood detection)
– SNMP: for monitoring network components and the
communication between the master and the device
I&M functions
Identication and maintenance data (I&M) is information sa-
ved in the module.
–The identification data is read-only manufacturer informa-
tion on the module.
–The maintenance data is system-independent information
created during the project planning process.
Modules can be easily identied online using the I&M data.
The following are supported:
–Module-specific I&M functions I&M 0–4 for the network
interfaces (slot0)
–The I&M functions specifically for IO-Link master I&M0
and I&M99 (IO-Link master directory) for the IO-Link
ports (slot1)
Alarm and diagnostic messages
The modules offer expanded PROFINET alarm and diag-
nostic messages.
Conguration and parameterisation
A GSDML le is needed to congure and parameterise the
module in the engineering tool.
The current GSDML le can be downloaded from
the Weidmüller website.
