Hi Sittner,
I know you're very busy, I've been looking at the example but I can't understand how your mod-bus code works, can I connect to a device using mod-bus ethernet ?, thanks

• I've been looking a little where I get, and if I can hear a TCP port

manual device configuration

supports slave (server) operation of Modbus TCP communication protocol. Modbus
TCP compatible devices on the network can read the values from the device and set the outputs. To
elevate the security, user can define which peripherals are accessible via Modbus TCP.
Modbus TCP uses TCP protocol on port 502 (default),I change 1502, which can be changed in Modbus settings
(accessible from the menu Device – Modbus configuration...). The Modbus TCP connection is
disconnected after 3 seconds of inactivity (this default value can be changed in the Modbus settings).
