EM58 – HS58 - HM58 MODBUS TCP/IP

6 MODBUS® TCP/IP interface

Lika MODBUS TCP/IP encoders are Slave (Server) devices and implement the
MODBUS application protocol (level 7 of OSI model) and the “MODBUS
messaging on TCP/IP” protocol (Ethernet: levels 1 & 2 of OSI model; TCP/IP:
levels 3 & 4 of OSI model).
For any further information or omitted specifications please refer to “MODBUS
Application Protocol Specification, Version V1.1b3” and “MODBUS messaging on
TCP/IP implementation guide, Version V1.0b” available at www.modbus.org.

6.1 MODBUS protocol principles

MODBUS is an application layer messaging protocol, positioned at level 7 of the
OSI   model,   which   provides   Client/Server   communication   between   devices
connected on different types of buses or networks. In particular, the MODBUS
TCP/IP   messaging   service   provides   a   Client/Server   communication   between
devices connected on an Ethernet TCP/IP network.
The   Modbus   protocol   was   developed   in   1979   by   Modicon,   for   industrial
automation   systems   and   Modicon   programmable   controllers.   It   has   since
become an industry standard method for the transfer of discrete/analogue I/O
information   and   register   data   between   industrial   control   and   monitoring
devices.

MODBUS devices communicate using a Master-Slave (Client-Server) technique
in which only one device (the Master/Client) can initiate transactions (called
queries). The other devices (Slaves/Servers) respond by supplying the requested
data to the Master, or by taking the action requested in the query. A Slave is any
peripheral device (I/O transducer, valve, network drive, or other measuring
device) which processes information and sends its output to the Master using
MODBUS.
Masters can address individual Slaves, or can initiate a broadcast message to all
Slaves. Slaves return a response to all queries addressed to them individually,
but do not respond to broadcast queries. Slaves do not initiate messages on
their own, they only respond to queries from the Master.

MODBUS TCP/IP (also MODBUS-TCP) is simply the MODBUS RTU protocol with a
TCP interface that runs on Ethernet.
The MODBUS messaging structure is the application protocol that defines the
rules for organizing and interpreting the data independent of the data
transmission medium.
TCP/IP refers to the Transmission Control Protocol and Internet Protocol, which
provides the transmission medium for MODBUS TCP/IP messaging.

Among the significant advantages of MODBUS TCP/IP are:

•

MODBUS TCP/IP simply takes the MODBUS instruction set and wraps
TCP/IP around it;
