Fieldbus: EtherCAT
Auto-configuration of I/O modules
I/O configuration and firmware update via the fieldbus (FoE)
Full support of the modular slice concept via CoE (CANopen over EtherCAT)
Configurable I/O cycle (0.2 to 4 ms)
Synchronization between the fieldbus and X2X Link
EtherCAT is an Ethernet-based fieldbus developed by Beckhoff. This protocol is suitable for both hard and soft real-time requirements in automation technology. In addition to a ring structure, which becomes logically necessary because of the summation frame telegram used, the EtherCAT technology also physically supports topologies such as line, tree, star (limited) and combinations of these topologies. B&R's X20BC80G3 (expandable bus controller module) and X20HB88G0 (standalone junction base module) are available for implementing these topologies.
EtherCAT slave devices take the data designated for them from a telegram as it is passing through the device. Input data is also added to the telegram as it is passing through. The bus controller allows X2X Link I/O modules to be coupled to EtherCAT and operated on any EtherCAT master system. A transition between IP20 and IP67 protection outside of the control cabinet is possible by arranging X20, X67 or XV modules one after the other as needed at distances up to 100 m.
Master systems without FoE (File access over EtherCAT) support require an appropriate configuration tool to transfer the configuration (optional).


20 safe digital inputs 4 pulse outputs Sink circuit Software input filter configurable for each channel This module is equipped with 20 safe digital inputs. It is designed for a nominal voltage of 24 VDC. The module can be used to read various digital signals in safety-related applications up to PL e or SIL 3. The module is equipped with filters that are individually configurable for switch-on and switch-off behavior. The module also provides pulse signals for diagnosing the sensor line. This module is designed for X20 12-pin terminal blocks.

Integrated motor detection
256 microsteps
Stall detection
Complete integration in Automation Studio and CNC applications
2x 3 inputs, 24 VDC, configurable for ABR incremental encoders
Integrated short-circuit proof encoder power supply
Function model 3 ("Ramp") based on CANopen communication profile DS402
NetTime timestamp: Position change, trigger time
The stepper motor module is used to control up to 2 stepper motors with a nominal voltage of 24 to 38.5 VDC ±25% at a motor current up to 3 A (5 A peak).
In addition, this module has 6 digital inputs that can be used as limit switches or encoder inputs.
Due to the individual adjustment of the coil currents, the motor is only operated with the current it actually needs. This simplifies the selection of the available motors and prevents unnecessary heating. Because this affects energy consumption and thermal load, the effects are positive on the service life of the complete system. Complete flexibility is achieved through the use of independently adjustable holding, boost and nominal current values. The current for microsteps is automatically adjusted to the configured current values.
The automatic motor identification system is an enormous help during standstills. The stepper motor modules can identify the connected motors using their coil characteristics and generate feedback in the form of an analog value. This makes it possible to detect not only wiring errors, but also incorrect motor types being used mistakenly. A stall detection mechanism is integrated to analyze the motor load. Detection of the stall is defined via a configurable threshold. This allows an overload or motor standstill to be detected precisely in many different types of applications.

Programmable logic controllers are ruggedized industrial computers that execute control logic for machine and process automation, handling digital and analog I/O, motion coordination, and network communication in real time across manufacturing and infrastructure environments. PLC Direct supplies programmable logic controllers as an independent supplier, carrying surplus sealed, refurbished, and used hardware for maintenance and replacement in installed automation systems.
Where Are Programmable Logic Controllers Used in Industrial Environments?
Programmable logic controllers are used wherever automated machine or process control requires deterministic, scan-based logic execution across digital and analog field signals. These controllers are installed across virtually every sector of industrial operations, from individual machine control panels to plant-wide distributed automation architectures.
Facilities and operations that depend on programmable logic controllers include:
-
Discrete manufacturing plants running assembly line automation, machine sequencing, and multi-axis motion control.
-
Food and beverage processing facilities managing conveyor systems, batch recipes, and filling line control.
-
Water and wastewater treatment plants controlling pump stations, dosing systems, and distributed process equipment.
-
Automotive and metal fabrication operations requiring high-speed discrete I/O and coordinated production line control.
-
Packaging, material handling, and logistics operations where flexible, modular control architectures support high-mix production environments.
Maintenance engineers and procurement teams sourcing replacement programmable logic controllers depend on the availability of both current-generation and legacy hardware to keep installed systems running without redesigning existing control architectures.
Which Brands of Programmable Logic Controllers Does PLC Direct Stock?
PLC Direct stocks programmable logic controllers across the major control platform brands deployed in installed automation systems worldwide.
-
Siemens SIMATIC S7 series: S7-300 and S7-400 modular controllers confirmed in stock, covering mid-range and high-end machine and process control applications across manufacturing and process industries.
-
Schneider Electric Modicon M340 and M580: Mid-range and high-end PAC platforms for machine and process control, with Modicon Quantum 140CPU series also stocked for larger installed process automation environments.
-
Mitsubishi Electric MELSEC iQ-R, Q Series, and FX5: Controller hardware spanning high-performance iQ-R CPUs, modular Q Series processors, and compact FX5 units for machine control applications across discrete manufacturing.
-
Omron Sysmac NX Series: NX1P2 CPU modules and associated I/O for Omron's machine automation platform, suited to packaging, assembly, and process control installations using EtherCAT and EtherNet/IP communication.
PLC Direct carries programmable logic controllers as surplus sealed, refurbished, and used hardware, giving maintenance teams and procurement managers options across condition grades and budget requirements.
What Should You Know Before Ordering Programmable Logic Controllers?
Hardware condition options: PLC Direct supplies programmable logic controllers in surplus sealed, refurbished, and used condition. Surplus sealed units are factory-sealed stock that has not been previously installed; refurbished controllers have been inspected and tested to confirm operational functionality; used hardware is sourced from decommissioned systems and suits facilities managing lifecycle replacements under budget constraints.
Compatibility and part identification: Programmable logic controllers are platform-specific, and CPU modules, I/O expansion, power supplies, and communication modules must be matched to the correct rack, backplane, and firmware environment for the installed system. Confirm the CPU part number, series designation, and any firmware or version requirements from existing system documentation before ordering. For legacy platforms such as the SIMATIC S7-300 and S7-400 or Modicon Quantum, verify rack slot and power supply compatibility as part of the identification process.
Warranty: All programmable logic controller hardware purchased from PLC Direct carries a standard 1-year PLC Direct warranty covering defects and functionality, applicable to surplus sealed, refurbished, and used products.
PLC Direct supplies programmable logic controller hardware for replacement and maintenance purposes and does not provide system design, programming, or integration services.
