Is MODBUS®
Protocol ?
MODBUS® Protocol is a messaging structure
developed by Modicon in 1979, used to establish
master-slave/client-server communication between intelligent
devices. It is a de facto standard, truly open and the most widely
used network protocol in the industrial manufacturing environment.
It is literally implemented by hundreds of vendors on thousands of
different devices in order to transfer discrete/analog I/O and
register data between control devices. It's really a lingua franca
or common denominator between different
manufacturers.
What
Is MODBUS®
TCP/IP Protocol ?
In order to move MODBUS® protocols into the 21st
century, an open MODBUS® TCP/IP specification has been developed
in 1999. Combining a versatile, scaleable, and ubiquitous physical
network (Ethernet) with a universal networking standard (TCP/IP)
and a vendor-neutral data representation (MODBUS® ) gives a truly
open, accessible network for exchange of process data. It is also
extremely simple to implement for any device that supports TCP/IP
sockets. Modbus/TCP basically embeds a Modbus frame into a TCP
frame in a simple manner. This is a connection-oriented transaction
which means every query expects a response. This query/response
technique fits well with the master/slave nature of Modbus, adding
to the deterministic advantage that Switched Ethernet offers
industrial users. .
ISEP
MODBUS® RTU to MODBUS® TCP/IP CONVERTER
TS502RTU is an intelligent and cost effective
protocol converter. TS502RTU facilities data communication between
MODBUS® RTU and MODBUS® TCP/IP. It
does this by sending MODBUS® TCP/IP queries to MODBUS® RTU
and vice versa. The MODBUS® RTU data are transmitted through
RS232/RS485 port and MODBUS® TCP/IP are transmitted through
ethernet port on the converter itself. It
also comes along with a extreme rugged casing and a din-rail
fitting which allows it to be used in any industrial applications.
