Easy-to-use Ethernet to RS-232/485/422 Modbus Gateway
|

|
Seamless Integration for Ethernet and Serial Modbus
Device
|
|
| |
Modbus is one of the most popular automation protocols in
the world. Modbus protocol supports traditional RS-232/422/485 devices
and newly developed Ethernet devices. Many industrial devices, such as
PLCs, DCSs, HMIs, instruments, and meters, use Modbus as their
communication standard. However, the Modbus protocol running over serial
and Ethernet are so different that a communication gateway is needed as
a bridge for integration.
NPort 6110 supports one Ethernet and one software selectable
RS-232/422/485 port that can connect with all kinds of Modbus devices.
By translating Modbus/TCP (Ethernet) and Modbus /ASCII/RTU (Serial)
protocols, a PLC with Ethernet can use the RS-232/422/485 interface to
seamlessly communicate with instruments.

Powerful Operation Modes for Versatile Modbus
Applications
|
| |
For Modbus protocol conversions, it is necessary to
define a Master and Slave device, but unlike other Modbus Gateways,
NPort 6110 allows users to configure Master/Slave for both the Ethernet
and serial sides. Extra address mapping and exception parameters are
supplied to ensure that most situations can be handled.

Windows Utility For Easy Setup and Traffic
Monitoring
|
| |
NPort
6110 is powerful yet very easy to use. An intuitive Windows utility
automatically searches for all available NPort 6110 units on the LAN.
Traffic monitoring within the utility helps you troubleshoot any Modbus
communication problem, such as connection status check, or address
translation error check. |
Typical Applications
Serial Master device talks to serial slave devices
over the Internet
|
| |
Let traditional Modbus serial devices talk over the Internet
Many traditional serial Modbus devices can talk over RS-485, but the
RS-485 network limits the maximum number of Modbus devices to 32, within
1.2 km. By using Modbus Gateway, you can link all Serial Modbus devices
over an Ethernet network. Up to 8 Modbus Gateways can be installed in
the same control network, extending the coverage of a single Modbus
network as far as a TCP/IP network can reach. |

Ethernet master devices talk to multiple serial
slave devices
|
| |
Connect all Modbus devices over the Ethernet network
Most host computers and newly developed PLCs support the Ethernet
interface and run Modbus/TCP. NPort 6110 Modbus Gateway is needed to
link discrete Serial Modbus Devices for data collection and control.
Each NPort 6110 supports Modbus/TCP over Ethernet, which allows up to 7
connections. The software configurable serial interface supports either
RS-232 or RS-422/485. In RS-232/422 modes, NPort 6110 can connect to 1
serial device. One NPort 6110 supports up to 31 serial devices under
RS-485 mode, which is the most popular application for the factory
floor. |

Serial master devices talk to multiple Ethernet
slave devices
|
| |
Link the Serial Master device with Ethernet Slave devices
Many HMI (Human Machine Interface) systems use a serial interface and
are required to access a discrete DCS. These days however, more and more
DCSs support Ethernet and run under Modbus/TCP slave mode. In this case,
NPort 6110 Modbus Gateway is the ideal solution to link the HMI to
distributed DCSs over an Ethernet network. Up to 4 Modbus/TCP slave
devices are supported for each NPort 6110. |

Easy-to-use Windows utility
|
| |
Configure Modbus Gateway Anywhere on the LAN
Once NPort 6110 is connected to the Ethernet, any Windows host computer
running Modbus Gateway Configurator can automatically search for all
installed Modbus Gateways, and then proceed with configuration. DHCP
(Automatic IP settings) and Manual IP settings are both supported. Such
user-friendly features make NPort 6110 one of the most easy-to-use
Modbus Gateways in the world.Online Traffic
Monitoring and Error Log Display
Modbus communication troubleshooting is both fast and easy. NPort 6110's
utility lets you monitor the online configuration and connection status
from anywhere on the network without interfering with operation.
Meanwhile, the system log can be stored as an installation or service
record.

Comprehensive and Powerful Modbus parameter
settings
|
| |
In
addition to working with most Modbus devices, NPort 6110 provides both
basic and advanced communication parameters. For example, in addition to
general configurations, Remote Modbus/TCP device ID, Initial Delay Time
Adjustment, and Character/Message Timeouts are adjustable right in the
Windows utility. Unlike text-based configuration from other vendors,
NPort 6110's comprehensive utility eases installation and saves training
cost for engineers. |
