Hi!
I have a working modbus RTU routine, but I get some errors sometimes so I wanted to add some delays between REQs. I didnt get it to work so I scaled the FB down to minimum but it still doesn't work. Shouldnt the two programs act the same? I get error 8200 (the port already in use with another request. So I get almost constant errors.
The FB has the same logic as when I dont use the FB. Is it processed some other way?
1. working
2. FB
3. Not working
