hi
Do you know which PLCs support MQTT?
What can be done if they dont support MQTT - would kepware with Direct Drivers be the only
option for the 4.0 connectivity?
Regards

 

PLCnext - Pheonix Contacts
Some Siemens (s1200)
Any Codesys PLC - so Wago, Beckhoff etc

Anything that supports node-red so some of the HMI Screens such as J-Mobile or Maple

thanks for reply - i really need to catch up on the new hardware types and brands

 

Hi hewking,
you can use IndigoSCADA as a gateway. On one side modbus client polling the server on the PLC and on the other side
MQTT client publishing to the cloud with sparkplug B payload.
Best regards,
apa

 

forgot to ask if PLC supports mqtt does it mean it will support spark plug b as well ? i hope my question make sense

 

opto22 groov epic supports MQTT sparkplug B payload encoding
