Modbus Gateway Solution

Overview
The M-Odbus protocol is a common language applied to electronic controllers. Through this protocol, the controller
By the Network (example
such as Ethernet) and other devices can communicate. It has become a general industry standard. With it, different manufacturers produce the
Control equipment can be
Centralized monitoring with a connected industrial network. However, the M-Odbus protocol is very difficult to run between the serial and Ethernet
This will require a
Communication gateways as a bridge to help integrate them.
The gateway supports an Ethernet and r s-232/422/485 port to connect various types of devices that support the M Odbus protocol. Pass
M odbus/tc P and M ODBUS/ASC I i/r TU Protocol conversion, PLC with Ethernet can use R s-232/422/485
interface to Real
Seamless communication with the instrument.
Networking Scenario One:
Network Scenario Description:
Traditional serial devices that support the M O D BU S protocol can communicate via R S-232 or R S-485, while the R S-485 network limits
Can have a maximum of 32 m O D BU s devices and can only have a maximum transmission distance of 1. 2KM. Through M O D BU s Communication Gateway, you can
Wildcard
Ethernet will connect all M o D bu s serial devices to extend the single m o d bu s network to the TC p/i P network.
To
Reach the place.

Networking Scenario Two:
Network Scenario Description:
The main device is an Ethernet interface and uses M O D BU S/TC p main mode. Through the gateway to connect the scattered m O D BU S
Serial port from the device, so as to achieve data acquisition and control purposes. (R s-232/r S-422 mode, a gateway can be connected to a
A serial device.
R S-485 mode, a gateway can support a maximum of 31 serial devices)
The Network diagram is:

Networking Scenario Three:
Network Scenario Description:
The main device uses serial communication, from the device has an Ethernet interface, and runs in M O D BU s/tc p slave mode. Gateway through the
Too
The network connects the serial main device and M o d bu s/tc p from the device, a maximum of 4 m o d bu s/tc p from the device.
