Standardized CANopen communication for industrial automation networks
The CANopen interface of the UC-CANOPEN-DIO8 is based on the internationally established CiA® specifications 301, 305, and 401 and enables reliable and standardized integration into industrial fieldbus environments. By supporting CAN 2.0A and CAN 2.0B, a high level of compatibility with a wide range of control and automation systems is ensured. Galvanic isolation of the bus connection provides robust signal transmission and reliably protects communication against interference in harsh industrial environments. Device addressing is conveniently carried out via integrated rotary coding switches, allowing the node ID to be set directly on the device at hardware level, which enables fast commissioning without additional configuration software. In addition, the baud rate can be flexibly adapted to the respective network, ensuring easy integration into existing system architectures. Furthermore, the interface on the module supports data rates of up to 1 Mbit/s as well as features such as auto-baud detection to further simplify commissioning. This results in a powerful, stable, and standards-compliant communication solution that supports both fast installation and reliable operation in industrial environments.
Flexible control via CANopen for easy system integration
The control of the UC-CANOPEN-DIO8 is fully based on the standardized CANopen protocol, enabling seamless integration into existing automation and control systems. By supporting the object-oriented communication model according to CiA 301, all functions are addressed and controlled via the Object Dictionary. Configuration is conveniently performed using standardized communication objects such as SDOs, while cyclic process data exchange via PDOs ensures fast and deterministic response in real-time operation.
In addition, the CANopen digital I/O (DIO) module supports typical CANopen Network Management (NMT) functions, enabling defined start, stop, and error states of the device within the network. Flexible assignment of node ID and baud rate simplifies adaptation to different network topologies and control environments. Thanks to this consistent implementation of the CANopen standard, the module can be efficiently integrated into existing automation architectures and centrally operated via the control system.
Compact DIN rail design with modular system integration
Das CANopen digital I/O (DIO) module ist für die Montage auf der DIN-Hutschiene ausgelegt und verfügt über ein kompaktes, industrietaugliches Gehäuse, das auf den Einsatz in rauen Automatisierungsumgebungen optimiert ist. Die elektrischen Anschlüsse sind über robuste, steckbare Klemmsysteme realisiert, die eine vibrationssichere Verdrahtung und eine schnelle Installation ermöglichen. Ein zentrales Merkmal ist der integrierte T-Bus, der als interner Systembus sowohl die Kommunikation als auch die Versorgungsspannung zwischen mehreren Modulen ohne zusätzliche Verdrahtung durchreicht. Dadurch entsteht eine durchgängige Backplane-Struktur, bei der Module mechanisch auf der Hutschiene verbunden und elektrisch automatisch gekoppelt werden. Der T-Bus reduziert den Verkabelungsaufwand erheblich und sorgt gleichzeitig für eine saubere, EMV-optimierte Systemarchitektur mit geringem Störpotenzial. Über die modulare Steckmechanik lassen sich weitere Teilnehmer einfach ergänzen, ohne das bestehende System neu verdrahten zu müssen. Die CANopen-Kommunikation des UC-CANOPEN-DIO8 wird dabei nahtlos in diese T-Bus-Struktur eingebettet, wodurch eine skalierbare und systematisch aufgebaute Netzwerktopologie entsteht.
Zusätzlich verfügt das CANopen digital I/O (DIO) module über integrierte Drehkodierschalter zur schnellen und einfachen Parametrierung direkt am Gerät. Über diese lassen sich zentrale Einstellungen wie beispielsweise die Node-ID ohne Softwarezugriff konfigurieren. Dies ermöglicht eine besonders schnelle Inbetriebnahme sowie eine eindeutige Geräteadressierung im Feld. Die Einstellung erfolgt dabei robust und manipulationssicher, auch im spannungslosen Zustand.

Digital inputs
Digital signal states can be recorded with our optocoupler inputs. Input and output circuits are electrically isolated from each other up to 2.5 kV.
Digital-in input filter
With our digital-in modules, an input filter can be set in a time interval of 1 ms...255 ms for filtering interference pulses.
Counter
Each input has a 16-bit counter.
Detection of state changes
Status changes that occur between readout cycles are reliably recorded by internal status change flip-flops and can be read out separately via software. In addition, such an event is signaled by a status LED.
Relay
Our digital outputs use power relays with normally open (NO) function.
All our relays are equipped with a software-based timeout protection function to protect against damage caused, for example, by contact breakage to the control PC.
Plug connector
A screwless system from the manufacturer WAGO® Kontakttechnik is used as the connector. The 1-wire female connectors are 100 % protected against mismating and have an ejection and locking mechanism.
Easy installation thanks to DIN rail bus
Thanks to the practical bus connector, which is clipped into the DIN rail, individual modules of a system can be added or replaced very easily. This Plug'n Play principle makes commissioning easier for you and eliminates the need for tedious wiring.
LEDs
Each digital input and output has a separate LED that lights up when the signal status is active. The status of the operating voltage, communication with the interface, error events or the occurrence of a timeout can also be displayed.

Configuration of CANopen modules
The CANopen interface is configured via the CANopen bus of the module and via three rotary coding switches located on the front of the module.
The upper and middle rotary coding switches determine the node ID, the lower one the baud rate.

Handling:
Steps 1-5
Step 1
See the scope of delivery for the operating tool.
Step 2
Insert the operating tool firmly into the side opening in the direction of the conductor connection.
Step 3
Now insert the stripped conductor into the open clamp contact.
Step 4
