Mery Christmas,
Althought the profile and script works fine i get an "Read failed: Operation time out" on modbus error log.
I have tried with just 2 registers on profile but i still get the same error.
The slave (DSE7320) is configured at 19200mbps / 2 stop bits / Half duplex and master inactivity timeout 10s
The LM RTU settings for RS485 are as above and also on profile i have poll interval 30s and timeout 10s.
There are only two devices connected on the BUS LM and DSE7320 at ~30m distance. I also have fitted both ends with 120 ohm resistors and connected the ground on each other.
Cable is a multicore unshielded 4x0,16mm usualy used in alarm systems, could that be a problem?
