Keep getting slave timeout error on PLC. TX light on PLC flashes and RX light on slave flashes, but still get time out error and no error response from slave.
- Have re-wired to test setup using a 1m cable.
- Have checked communications of PLC and slave match: RTU/9600/8 bits/no parity/1 stop bit.
- Have tried with and without terminating resistor.
- Have tried with and without connecting the signal ground to a clean earth.
- Have followed programming example in FX5U manual.
If anyone's interested, I can email screenshots of everything and a photo of the wiring. Please email me at

Many thanks!
