4. GENERAL INFORMATION ABOUT ModBus ARCHITECTURE
4.1 System overview
ModBus is a serial communication protocol created by Modicon in 1979 . It became standard in industrial
communication , and is currently one of the most popular connection protocols in the world between industrial
electronic devices. The main reasons for such a high usage compared to other ModBus communication
protocols are:
•It is a protocol openly published and royalty-free
•Move raw bits and words without placing many restrictions on producers
The protocol defines the format and the communication mode between a "master" who manages the system
and one or more "slaves” that respond to the master. The Protocol defines how the master and the slaves and
disrupt communication, such as transmitter and receiver must be identified, such as messages need to be
exchanged and how the errors detected.
Only the master can start a transaction that can have the question/answer format directly to a single slave or
broadcast when the message is sent to all devices on the line that give no response. A transaction consists of
a single structure question/single answer or a single broadcast message/no answer. Some features of the
protocol are:
•Baud rate
•Parity
•Number of stop bits
•and size RTU (binary)
As mentioned above the transactions always involve the ModBus master, which operates the line, and one
slave at a time (except in the case of broadcast messages). To identify the recipient of the message is sent as
the first character a byte containing the numeric address of the selected slave device. Each slave will then be
assigned a different number of address that uniquely identifies it. Admissible address are from 1 to 254 , while
the address 0, which can’t be assigned to a slave, place on top of the message sent by the master indicates
that it is "broadcast", that is directed to all slaves simultaneously.
Below is showed a standard architecture for the physical connection of n ModBus devices.

than 110)
•Netmask: 255.255.255.0
•IP allocation: Static
•To change the IP address of the computer network adapter, refer to the user manual of the Operating
System of your PC
•In the event that the PC and the RTU are connected via an existing LAN (company or domestic
network), make sure not to allocate the IP address of the RTU or of the PC
•For instructions on how to change the IP address of your PC, refer to your current OS
5.4 Connection to a GPRS-UMTS modem/router
A data connection to access the Internet ensures remote consultation of the webserver, sending of
consumption reports, and monitoring of the system. Should a LAN/ADSL connection not be available, you must
use a modem/router supplied as an option of the RTU.
The default settings of the RTU and SIN.ROUTER allow the connection of the two devices without having to
change their network parameters. The router is configured to use a TIM (Telecom Italia Mobile) SIM. In this
case, the user must carry out the following operations:
•Power off the router.
•Remove the front panel where the place to insert the SIM is indicated
•Ensure that the SIM PIN is disabled
•Insert the data SIM in the right direction
•Close the front panel
•Fasten the two GSM MAIN and AUX antennas to ensure sufficient transmission signal
•Wait for the router to connect to the mobile network
•Use a network cable to connect port LAN1 of the router to port ETH1 or ETH2 of the RTU
•Verify that the Internet connection is OK from the display (section RTU INFO, Chapter 8.3)
Should a TIM SIM not be available, the operator will have to change some router settings:
•Verify whether it is a Machine-To-Machine (M2M) SIM
•It is enabled for GPRS/UMTS traffic
•Check with the operator that it is bidirectional. i.e. that it allows access to port 80 for webserver
consultation
•Change the APN of the router with the one provided by the operator (e.g. ibox.tim.it /
m2mbis.vodafone.it)
Refer to the Appendix (Chapter 20) for in-detail information on router settings.

9. CONNECTING THE RTU TO THE PC
Connect the RTU either to ETH1 or ETH2 using a T568A or T568B (straight through or crossover) Ethernet cable
as shown in Figure 12
Figure 12 - LAN connection
Set the network adapter of your PC in such a way as to allow communication between the two devices. Below
is a description of a possible configuration of the LAN between the two devices in the event that the RTU IP
address has not been changed, as shown in Chapter 5.3, 8.3
Carefully read the following notes
In order for the RTU and PC to communicate, the two devices must have an IP address within the same subnet.
The default RTU network settings are:
•IP address: 192.168.1.110
•Netmask: 255.255.255.0
•IP allocation: Static
In order for the computer to communicate with the RTU via Ethernet, the IP address of the computer’s network
adapter must be set as follows:
•IP address: 192.168.1.XXX (With XXX being a number ranging between 1 and 254 and different than 110)
•Netmask: 255.255.255.0
•IP allocation: Static
To change the IP address of your computer’ network adapter, refer to its Operating System user guide.
In the event that the PC and the RTU are connected via an existing LAN (company or domestic network),
make sure not to allocate the IP address of the RTU or of the PC.
In the event that the default IP address of the RTU has been changed, you can consult the current IP address
as described in Chapters 5.3, 8.3.
