ENOCEAN remote controls with 750-940 gateway connected to a 750-652 module (RS485) on pfc200 8212

I am currently stuck because card 642 is no longer available. I therefore wish to retrieve the validation of a 4-button ENOCEAN remote control button via gateway 750-940. This gateway is wired to a 750-652 RS485 card. Two questions: how should I connect the gateway to the card? 1) Is the following schematic diagram correct? 2) Which function block can I use to interpret the encapsulated ESP3 data circulating via Modbus?

I think you should connect it like this:


And since you are used to the 750-652 i would recommend to use the ESP3 mode and the WagoAppEnocean library with the 640 function block.

Hello WagoIcard. Thank you for the wiring advice. Regarding the functional block, are we talking about the FbModule_750_642 or FbEnocean_750_642?

Oops I mean since you are used to the 750-642.

Under codesys 2.3 you should have in the library “Enocean_06.lib” the function block: “FbEnOcean_750_940_RS485”
And under codesys 3.5 you should have in the library “WagoAppEnocean” the function block: “FbEnOcean_750_940_RS485”

With those function blocks the EnOcean gateway should work like with the 750-642.

Using the FbEnocean_750_642, I successfully receive frames on my buffer, but I have no frames in the FbEnocean_750_940_RS485. My baud rate is set to 115200, data bits to 8, and parity to none.

Also, when I’m not online with the controller, the C LED on the 750-652 card flashes green when I press a button on the soft remote. When I switch to online mode, it flashes red as if the frames were becoming incomplete. I’ve tested many functional blocks from the WagoEnOcean library, but nothing works.

Are we really sure about the hardware compatibility?

First you can’t use 2 function block on the same hardware.
Please delete the 642 function block and try only with the 940 function block.
The main reason why the 940 is not working is: the com port (652) is already taken by the 642 function block and can’t be opened again. (like if your configuration cable, the USB or serial cable to configure the 750-3xx or 750-8xx, if you have a I/O check communication, you can’t use the same port for the Ethernet setting without disconnecting from I/O Check.)

I tested everything. The recbuffers vary, but I never see 246 (decimal) pass through. The 750-940 gateway does not work properly with Nodon soft remotes.

Hello,
Took me some time to find the gateway.

Here is how I set it:

You can see what cable goes where.

For the program:

And the data came without any problem.
Can you share the cabling you have done, dip switch settings and program ?
