IEC 61558-2-6 or equivalent. The CE declaration of conformity of the device can be requested from Eelectron SpA, at the contacts on the website www.eelectron.com In accordance with Directive 2002/96/EC, electronic devices must be disposed of in dedicated facilities and not in the collection of municipal solid waste. -

INTRODUCTION Introduction HORIZONE can use the Modbus RTU and Modbus TCP/IP protocol to supervise one or more slave devices, connected via both RS485 and network connection. Once communication logs are configured with a Modbus slave device, they can be managed as objects on the supervision pages or associated with other objects using logic. - Page 6 ● Press the “SAVE” button and wait for the page to reload Refer to the INSTALLATION MANUAL for further details.

502. Preliminary operations Before starting the configuration of a Modbus device in HORIZONE SERVER, it is necessary to obtain the table (or “mapping”) of the read and/or write logs. You will be able to identify the useful... - Page 8 Eligible addresses on a Modbus network range from 1 to 247. The Master device of the line, which in our case will always be HORIZONE, does not need an address for communication while address 0 is reserved for “broadcast”...
- Page 9 Modbus, whether they are read, write or both. Since they are HORIZONE objects, they can be used for each of the server functions: schedules, logics, conditions, composite objects, etc.
- Page 10 Modbus device, resolving any problems encountered, integration on HORIZONE will be easier and faster. Obviously, this procedure must be followed for each device that you want to insert into a HORIZONE line. You can find lots of free Modbus Master programs on the internet; we recommend the following: http://www.modbustools.com/modbus_poll.html...

It is also possible to manage more than one slave device if connected in a “cascade” to the same RS485 line, thus creating only one line in HORIZONE and differentiating devices through the slave address, as further detailed below. In this case, all devices must operate with the same communication parameters (BAUD rate, parity, etc.) - Page 12 “Download Log” button. This tool can be useful during the commissioning of Modbus devices with HORIZONE but, once the system is operational, it is recommended to activate it only if strictly necessary (e.g. maintenance or software modifications).
- Page 13 The following parameters must be entered for serial communication: SERIAL PORT Determines which communication channel HORIZONE will use to connect to the Modbus devices connected. You can use any of the serial ports of the HORIZONE: ● External RS232 port ● USB port 1 ● USB port 2 When connecting to HORIZONE USB ports, a USB-serial adapter must be provided.
- Page 14 The “CLEAR LOG” button clears the contents of the Log file by deleting all previously logged messages and reducing the size. The “Enable Communication” flag, if not selected, allows you to maintain the configuration of a bus line within the project, but make communication inert.

MODBUS REGISTERS Creation of registers To create one or more registers for each slave connected to the HORIZONE Modbus line: ● Access the Modbus Line ● Type the number of registers to create in the text field next to the “ADD” button under the section title “MODBUS REGISTERS”... - Page 16 ● Preset Single Register (FC06) ● Force Multiple Coils (FC15) ● Preset Multiple Registers (FC16) Allows you to determine the number of registers to be read and/or written simultaneously.
