KEBA DI260/A Digital Input Module

Product Details

DI260/A Product Description

The KEBA DI260/A is a high-performance digital input module engineered for seamless integration within the KeControl C5 PLC platform. Operating over the EtherCAT real-time fieldbus protocol, the DI260/A delivers deterministic signal acquisition from field-level sensors and actuators directly into the controller's process image — forming a critical node in the smart factory data chain. Whether deployed in machine automation, process control, or energy management applications, this module bridges the gap between physical I/O signals and the digital intelligence layer of modern industrial networks.

In a connected factory architecture, data integrity begins at the field device level. The DI260/A captures discrete digital signals — from proximity switches, limit switches, push-buttons, and safety interlocks — and transmits them with sub-millisecond cycle times across the EtherCAT network to the KeControl C5 controller. This real-time data path ensures that the PLC's logic engine always operates on current, accurate field states, enabling precise sequencing, rapid fault detection, and reliable closed-loop control across the entire production line.

Beyond raw signal acquisition, the DI260/A plays a pivotal role in the broader data flow architecture that connects field devices to supervisory systems. Once digital input states are captured and processed by the KeControl C5, the data is made available upstream to SCADA and HMI platforms via OPC-UA or Modbus TCP gateways, enabling operators to monitor machine states, track alarm histories, and visualise production KPIs in real time. This transparent data path — from sensor to screen — is the foundation of effective remote diagnostics and predictive maintenance strategies.

The KEBA DI260/A sits at the foundation of a layered industrial data architecture. At the field level, discrete sensors — including inductive proximity sensors, photoelectric switches, and mechanical limit switches — feed their binary states into the DI260/A's input channels. The module aggregates these signals and transmits them over the EtherCAT network to the KEBA KeControl C5 controller, which executes the programmed IEC 61131-3 logic in real time.

Within a typical smart factory cell, the KeControl C5 may also communicate with a KEBA CP260/A CPU module or coordinate with KEBA AO260/A analogue output modules to drive variable-speed drives and servo actuators. The DI260/A's input data — representing machine states such as door-open, part-present, or cycle-complete — feeds directly into the controller's process image, where it influences output commands sent to KEBA DO260/A digital output modules controlling solenoid valves, indicator lights, and relay outputs.

As the data moves upstream, an OPC-UA gateway or Modbus TCP bridge translates the EtherCAT process data into a format consumable by SCADA platforms such as Wonderware, Ignition, or WinCC. Operators at the HMI level — using KEBA KeView panel PCs or third-party touch panels — can monitor the live status of every digital input channel, review historical alarm logs, and configure threshold-based alerts. This end-to-end visibility transforms raw field signals into actionable operational intelligence.

For multi-axis or multi-zone production lines, the DI260/A integrates naturally alongside KEBA KeMotion motion controllers and KEBA KeTop handheld terminals, enabling coordinated control across robotic cells, conveyor systems, and assembly stations. Industrial Ethernet switches — such as managed switches supporting EtherCAT topology — ensure network redundancy and deterministic data delivery across the factory floor. Edge computing nodes can further aggregate DI260/A data streams for local analytics, anomaly detection, and cloud-based reporting, completing the digital thread from sensor to enterprise system.

Many industrial sites face persistent challenges: fragmented I/O architectures, protocol mismatches between legacy field devices and modern controllers, and limited visibility into machine states at the supervisory level. The KEBA DI260/A directly addresses these pain points within EtherCAT-based KeControl C5 environments.

Protocol Unification: By standardising digital input acquisition on the EtherCAT protocol, the DI260/A eliminates the need for protocol converters between field sensors and the PLC. All input data arrives at the controller in a single, coherent process image, reducing integration complexity and potential points of failure.

Eliminating Data Silos: When combined with OPC-UA or Modbus TCP gateways, the DI260/A's data becomes accessible to SCADA, MES, and ERP systems — breaking down the information barriers that prevent production managers from making data-driven decisions. Real-time dashboards can display machine uptime, cycle counts, and fault frequencies derived directly from DI260/A input states.

Remote Monitoring and Diagnostics: EtherCAT's built-in diagnostic capabilities, combined with the KeControl C5's remote access features, allow maintenance engineers to interrogate individual input channel states, identify wiring faults, and diagnose intermittent sensor failures without physical site visits. This capability is particularly valuable for geographically distributed production facilities or unmanned night-shift operations.

Production Line Transparency: By mapping DI260/A input channels to SCADA alarm tags, operators gain immediate notification of abnormal machine states — whether a safety gate has been opened, a conveyor jam has occurred, or a sensor has failed. Alarm histories provide the audit trail needed for root-cause analysis and continuous improvement initiatives.

Scalable Expansion: The modular architecture of the KeControl C5 platform allows additional DI260/A modules to be added as production lines expand, without redesigning the control architecture. New input channels are automatically recognised by the EtherCAT master and integrated into the existing process image, ensuring a future-proof I/O infrastructure.

Q1: What is the communication latency of the KEBA DI260/A over EtherCAT? The DI260/A operates within the EtherCAT real-time protocol, which supports cycle times as low as 100 microseconds. In typical KeControl C5 configurations, digital input data is refreshed within the PLC scan cycle — generally 1–10 ms depending on the application — ensuring deterministic, low-latency signal acquisition suitable for high-speed machine control and safety-critical applications.

Q2: Is the DI260/A compatible with third-party EtherCAT masters or only KEBA KeControl C5? The DI260/A is optimised and validated for use with the KEBA KeControl C5 EtherCAT master. While EtherCAT is an open standard (IEC 61158), compatibility with third-party EtherCAT masters depends on the ESI (EtherCAT Slave Information) file support of the master controller. For guaranteed interoperability and full diagnostic support, deployment within the KeControl C5 ecosystem is recommended.

Q3: How does the DI260/A support remote diagnostics and network stability monitoring? The KeControl C5 platform provides integrated EtherCAT network diagnostics, including frame error counters, link status monitoring, and slave device health reporting. These diagnostics are accessible via the KeControl engineering environment and can be exposed to SCADA systems via OPC-UA, enabling remote monitoring of network stability, early detection of cable degradation, and proactive maintenance scheduling — all without interrupting production.

Q4: What warranty and pre-shipment testing does the DI260/A include? Every KEBA DI260/A supplied by NANKMOS is covered by a 12-Month Warranty from the date of shipment. Prior to dispatch, each unit undergoes functional verification to confirm correct EtherCAT communication, input channel integrity, and electrical compliance. In-stock units are available for immediate shipment, minimising downtime for urgent replacement or new installation projects.
