Question
What is the difference between output.content and output.telnet in DataMan scripting in my Edge Intelligence setup?
Answer
- DataMan - Edge Intelligence (Standard Results)
- Edge Intelligence Essentials gets the DataMan results from output.telnet.
- output.telnet will get the value of output.content if it’s not set.
- If output.telnet and output.content both are set, Edge Intelligence will get whatever is set on output.telnet.
DataMan - Edge Intelligence (Tunnel Trigger Results)
- Tunnel Manager systems doesn't use output.telnet for the "Tunnel Trigger Result".
- Tunnel Manager gets its data through port 47777.
Dataman - PLC
- DataMan also interacts with PLC using a variety of factory floor protocols, That communication goes through output.IndustrialProtocol.
- If PLC communication is configured to be sent via output.telnet, then that will also be fed to Edge Intelligence's "Standard" Trigger results.
Types of protocol use for PLCs
- If you're using a Mitsubishi PLC, then you'd probably use SLMP.
- If you're using a Siemens PLC, then Profinet.
- If you're using Rockwell/Allen-Bradley, then EtherNet/IP
