MODBUS TCP / IP
System architecture
The connection between Elfocontrol2 (EC2) and the home automation system is done using a device called "Sten".
The home automation system must implement a modbus communication TCP/IP over ethernet connection
The registers are NOT retentive, ie a possible reset voltage implies that the system update again all necessary records.
The settings determined by the external system does not change local ones to EC2 (all the user configuration keeps the values stored in the
configuration XML file); in the case of an external system disconnection, EC2 will use the values in the configuration file.
Communication mode
Deafult parameters Modbus TCP/IP side connection:
Address IP: 10.0.0.141
Doors TCP: 23
Modbus address: 190
By connecting to the address http://10.0.0.141:8680 You can change these settings (password required). Caution: changing settings RTU side will
cause the lack of communication between EC2 and Sten. The DHCP client is not active, do not enable it.
Currently Sten only accepts commands modbus 03 in reading and 16 in writing.

Heart bit for communication timeout handling
The register address 0 is used by EC2 to determine if the external system is properly connected. The system will have to write at least every minute, a
value other than 0. EC2, once read a value other than 0, consider the system connected and will use the data read on Sten in those "local" to thermo-
regulate system.
Just read the value, EC2 puts it back to 0, and if within a minute the system not puts it to a value different from 0, EC2 one considers disconnected
and back to work in stand-alone mode, using its own local settings.
