ctrlX PLC offers a scalable PLC control solution and combines the advantages of classic PLC automation with the communication and functional requirements of the Internet of Things – a perfect combination for the Factory of the Future. ctrlX AUTOMATION is embedded into the open automation platform and based on the innovative Embedded Linux Ubuntu Core operating system with real-time extension and enables problem-free extension of functions via apps. ctrlX PLC can be individually adjusted to the respective task at hand. For this, apps from the ctrlX Store as well as third-party apps can be used. Security is always top priority starting with the configuration of ctrlX AUTOMATION, the security-by-design approach down to dedicated security apps for firewall and VPN which can be individually added and are certified according to IEC 62443.

Already the entry-level version offers more program and retain data memory than most comparable solutions. Ready-made function modules, program templates and automatic code generation via one REST interface increase effectiveness and efficiency in engineering. The ctrlX Data Layer centrally provides the data selected by the user for seamless integration with other apps. Via established standards like OPC UA or MQTT, the data can be exchanged with other systems. For control of servo drives, E/A and other field devices, ctrlX AUTOMATION mostly uses the proven performance and reliability of EtherCAT. Networking with other control systems is possible via OPC UA, PROFINET and Ethernet/IP. For networking via OPC UA, Bosch Rexroth promptly implements the definitions of the Field Level Communication Initiative in the OPC Foundation to offer sustainable solutions to its users. This means that ctrlX PLC can be integrated in the most varied automation environments. Via the ctrlX Device Portal, ctrlX PLC system can be centrally managed.

The ctrlX PLC app offers a scalable PLC runtime system based on CoDeSys V3, which is completed by comprehensive technology libraries by Bosch Rexroth.

Notes on PLC licensing
  • ctrlX PLC Basic (01VRS) Single license (SWL-XC*-PLC-PLC**********-BANN)
    enables the PLC for Single Core, Single Task usage.
  • ctrlX PLC Standard (01VRS / add-on) Single license (SWL-XC*-PLC-PLC**********-NNNN)
    is the upgrade to Single Core, Multitask usage (ctrlX PLC Basic required).
  • ctrlX PLC Advanced (01VRS / add-on) Single license (SWL-XC*-PLC-PLC**********-ADNN)
    is the upgrade to Multicore, Multitask usage (ctrlX PLC Standard required).
  • ctrlX PLC Performance (01VRS / add-on) Single license (SWL-XC*-PLC-PLC**********-PRNN)
    is the upgrade for ctrlX CORE X7 (ctrlX PLC Advanced required).
PLC 02VRS+ (announcement | available with ctrlX AUTOMATION 2.06 LTS)

With the new license model, ctrlX PLC licenses can be selected independently of the hardware used. Scaling factors are now consistently the usable tasks, CPU cores and new - the number of IO data used. This means that the new license model is hardware-independent and allows the consistent use of ctrlX CORE through to 3rd party hardware with ctrlX OS.

  • ctrlX PLC Basic (02VRS+) Single license (SWL-XC*-PLC-PLC*XOS******-BANN) - IEC 61131
    PLC runtime with support for single core, single task and 256 byte IO data.
  • ctrlX PLC Standard (02VRS+ / add-on) Single license (SWL-XC*-PLC-PLC*XOS******-NNNN) - IEC 61131 PLC runtime with support for single core, multiple tasks and 1 kByte IO data - upgrade of PLC Basic license.
  • ctrlX PLC Advanced (02VRS+ / add-on) Single license (SWL-XC*-PLC-PLC*XOS******-ADNN) - IEC 61131 PLC runtime with support for multiple cores, multiple tasks and 2 kByte IO data - upgrade of PLC Standard license.
  • ctrlX PLC Performance (02VRS+ / add-on) Single license (SWL-XC*-PLC-PLC*XOS******-PRNN) - IEC 61131 PLC runtime with support for multiple cores, multiple tasks and max. IO data - upgrade of PLC Advanced license.
License parameters IO data

The license parameter IO data has been newly introduced as a scaling parameter and refers to the IO data that is processed in the PLC. Exactly, that means all IO data that is configured below a CODESYS fieldbus or below the EtherCAT Master Data Layer RT node and used in the program is taken into account by the license parameter. This includes all IOs used in the PLC program below the following nodes:

  • CODESYS ProfiNet Controller / Device
  • CODESYS EtherNET/IP scanners / adapters
  • EtherCAT masters

Latest features in version 0120.4
  • Library CXAC_Diagnostics - Registering or sending diagnostic;
    managing individual diagnostic messages 
  • Support of ctrlX CORE X7
  • PLC method call - Parameter of type ENUM
  • Updated PLC Web UI - Project information
  • Integration of CODESYS runtime
