modbus RTU vis RS485 timeout error 6101.

[igohilandi]

Hello,

i have the same problem of timeout (6101) when i use the modbus query write single register.

the setting of the parity are the same and the library is up to date.

when i am using query read or write only no problem at all.

Any ideas?

thank you

Do you know if the device supports that command? Perhaps it will only support Write Multiple Registers.

[igohilandi]

Yes it support it because when i only write without reading no problem at all and when i only read without writing no problem at all. but the problem occur when i am reading then writing or vise versa.
