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
Regards
Jochen
