Communication between ctrlX core's

[Yvonne_]

What possibilities are there, for communication between two ctrlX cores (C2C)? Is this just OPC UA, or is there e.g. a possibility for a shared data layer, where core 1 can directly read/write a variable on core 2?

Hello Yvonne

There are several ways for a control - control communication.

++++++++ Update 09.03.2023 +++++++++

• OPC UA (PubSub) - NRT still available, in the future the base of the RT-C2C
• Datalayer connection via remote device - NRT and (as far I have in mind very slow)
• PLC data exchange via
  • socket communication
  • CODESYS net variables
• Ethercat
  • Master is available
  • Slave is planned after 2025 (ctrlX COREplus)
• ProfiNet
  • Device is available since begin of 2023 (for some HW variants - ctrlX COREplus, ctrlX DRIVEplus)
  • Master planned for Q2/2024 (ctrlX COREplus)
• Modbus TCP (since Q3/2022)

Recommendation:Use OPC UA
