Modbus ethernet baud rate AC700F
Hello !
I have a data transfert problem between my AC700F and my Panel 800.
There sometimes are timeouts with the connection. I think it's the baud transfer wich is not correct.
Do you know how to change the baud rate for the communication with modbus ethernet between AC700F (CBF 2013) and a Panel 800 (Panel Builder 800 Version 5)
Thanks

Hello,
Baudrate setting is for Modbus rtu not in Modbus TCP, But you can try changing timeout value. by default it is 15s for both master/slave object. you can try 20s or 25s value....
OR can keep modbus read/write blocks in slower task cycle task. OR if you are a master them for read/write block can avoid autorequest and can use REQ pin by providing a pulse...

Thanks for your answer !
I notice that sometimes, a variable can take 30s to change, between the panel and the AC700F. I check the "slow down send cycle", and it's better, but the problem is always here. I will change the timeout value.

Yes my problem is solved !
I used the pin REQ, and not the Auto request. There is no timeout anymore !
Thanks
Simon
