I have a beckhoff EL7041-1000 rev 21 in my ethercat bus but it wont correctly create a softmotion axis unless i manually insert the device. scan for devices gives me an el7041-1000 without an SM3 axis.

The structure should be the same independent of which runtime version. Im using Codesys control for linux SL. Ie, add an ethernet device, then profinet controler then phoenix PN bus coupler.

is the bus running.? what type of values/IO is the adaptor providing? do you have a map of the data layout? are you actually looking at the right offset?

Ja, Gerätebaum ist grün/orange (siehe Bild). IO-Variablen sind gemappt und im Programm verwendet. Ich habe mal noch ein paar Bilder zum Status angehangen.

CODESYS Control for Raspberry Pi MC Does CODESYS use its own native driver for I2c? I have a python script communicating with a device simultaneously with a CODESYS doing the same. The bus is not saturated. But I get many read errors

Es funktioniert nun. Ich hatte die SYNC-Erzeugung im CANOpen-Manager vergessen. Mit dessen Aktivierung empfange ich die Daten in der Soft-SPS. Vielen Dank für die Hilfe bis hierhin :) Btw: Die PDO's waren standardmäßig als Übertragungstyp zyklisch-synchron eingestellt.

I am curious if there is a function block or function that will allow me to monitor the J1939 CANBus and pull out all of the SAs that are on a particular bus, without having to have them loaded in the J1939 manager?

yes I think you need to build the kernel drivers for the CCAT driver for the backplane ETC networkcard https://github.com/Beckhoff/CCAT/

256MB for the protocol yes, but the default value for this library parameter limits the library to 6kB per task scan.

if this does not work, you could install the 3.5.20.0 Gateway from the CODESYS Store. https://store.codesys.com/de/codesys-edge-gateway-for-windows.html then it is possible to enable it by righclick inthr task tray

"Save Cyclic" is set to 30s, but in my log I can see my variables are logged every 500ms which equals the cyclic time for my Task. Why is "Save Cyclic" ignored

Thanks everyone for your input, I am using persistent variables to retain the timer value after machine shutdown, and main task to be as low as possible for the seconds TON to be accurate.

Hi arundara, I'm also experimenting with Redundandcy. Is the sync variable function the following: "RedundancySynchronizeData()" ? Does the Task time increase a lot when you activate the sync function?

the project has only one OneWire Master - so if you add the setting "PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ to the config file it will fail and the Ethercat task will be blocked by the OneWire Master readings?

I can't answer why it's not resetting, but from the description of g_udiMaxReceiveBufferSize, I would guess the sum of sizes of the mqtt packets received in one cycle exceeded this value. So the answer may be to increase that parameter. https://content.helpme-codesys.com/en/libs/MQTT%20Client%20SL/Current/MQTT-Client/Common/Params/MQTTParam.html https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_dlg_library_parameter.html

OK, that makes sense. Because the FB is provided a specific interval period, it would change the target position accordingly based on the time it "thought" elapsed. If it has the wrong interval provided, it updates the target positions every cycle incorrectly so the axes will end up moving faster or slower. Thanks!

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
