We recommend OPC UA for control to control communication due to the following reasons:
- Generally accepted standard
- 3rd party interoperability
- IT Security integrated
- Roadmap for real-time capability available
Depending on your real-time requirements a solution is possible with ctrlX 01V12 or future releases.
If the criteria above are of less importance the CODESYS network variables are an alternative solution.
What are your requirements?
- Amount of data
- Communication cycle time and latency
- Project roadmap
