Welcome back. Currently, the stage has stopped at the set value. It seems to be, but not stable. It appears at various intervals. I transfer data via SDO. PDO somehow doesn't want to transfer data. As I wrote, bit control is still there. I'm still fighting, although I'm slowly running out of ideas. If you have any ideas, I'd love to try them out. As for PDO, I don't know why it doesn't react at all. On no channel.
The assignment format is ok.

I fixed the NMT
Kratmel, do you have a description of the C0520 code? Described in the manual as service code LENZE and no information. By setting its parameter (10000), he switched it to verbal ordering of signals from the module
INTERBUS or PROFIBUS function. -
As for PDO addressing, it is the same as in the Unitronics program. Data transfer doesn't trigger anything. I started sync. when sending SDO to the same address, I run the inverter with respect to the set bits, but I have a problem with the set value.
according to the instructions, the process channel is C0395 - input data,
C0396 - output data.
Where the first 2 bytes are the inverter status bits, e.g.
unlocking, JOG speed etc. And the next two are the set value. And that's what I have a problem with.It is possible that I sent NMT stop to the inverter by mistake and that is why it does not want to switch to network start.

I put in variables. It didn't help. Some settings have disappeared and I cannot put the inverter into operational mode, as if the NMT plc was not sending. I've set the status of the bits that disappeared, but I'm still struggling with the set value. If anyone has any ideas, they're welcome. Thanks for the help.

I'm changing my tactics, I'm trying to use PDO, maybe it will work better. At the moment, I do not want to change the inverter settings because I will be creating software for the existing Can setup. A total of 3 inverters and a servo drive.

Coś nie idzie dobrze, gdzie popełniłem błąd? Zgodnie z instrukcją za odblokowanie dysku odpowiada bit 10 w pierwszych bajtach. Ustawiłem więc bity i wysłałem je przez SDO i działa. Dodam, że korzystałem z kanału synch. W tym telegramie ustawiając bajty 2 i 3 ustawiana jest ustawiona prędkość, więc dodaję blok struct i pierwsze bajty działają, ale nie ma ustawionej prędkości.
Kratmel, dziękuję za pomocne pliki, mam E82ZAFC kartę komunikacyjną.

Witam serdecznie. Mam kilka pytań odnośnie CanOpen. Czytanie pomocy i przeglądanie projektów pomogło mi zrozumieć niektóre z nich, ale nadal mam następujące:
1. Jaka jest różnica między PDO a SDO?
2. Czy wszystkie kroki konfiguracji wysyłania i odbierania muszą zostać wykonane?
3. Jeśli wysyłam SDO, które w zawartości ma 4 bajty słowa sterującego i 4 wartości zadanej to jak je połączyć?
4. Czy falownik zapamiętuje ostatnio wysłane polecenie? Czy jego bufor wejściowy powinien zostać zresetowany?

Kratmel, thank you for your help. SDO and PDO are finally working, now I'm still struggling with receiving the status
NMT, to control the network, I did as in the example, but something does not work. Will the inverter itself respond to the status inquiry sent? Do I need to set any parameter again?
This is this part of the program.
