Ethercat : Control mode ("init", "OP"...) via JSON/Node red or PLC

[Franck_FR]

One example why we need to control the Ethercat's modes :

Configuration EFC5610 + CtrlX CORE (Ethercat)

When we power the devices on, The EFC stays in Pre-OP, so we need to set "init" state and then "op" state to make it work.

So we need to make it automaticaly with PLC or JSON code when we start the devices.

Firstly I try to do it directly from the datalayer (JSON) but I don't find the right syntaxe.

Do you have tips to do it from Node Red or PLC ?

Thank's in advance,

Hi Franck_FR,

from the PLC you can take the function block "IL_ECATMasterSetBusState" from the library "CXA_ETHERCATMASTER".

See screenshot or example project:

And here attached an example flow for NodeRED with two different types how to change the Master State.

Thank's, both ways work well 😃
