1. You may use a DB9 to DB9 cable to connect your serial device to NPort 6110. Plug one end of the cable into the port on the back panel of NPort 6110 and plug the other end into your serial device’s serial port. -
Page 16: Ethernet Installation
There are two ways to use the 10/100BaseT Ethernet jack located on NPort 6110’s front panel: 1. For most applications using NPort 6110, you will simply plug one end of an Ethernet cable into NPort 6110’s 100BaseT jack, and plug the other end into an Ethernet hub/switch connected to your network. - Page 17 2. You will be greeted by the Welcome window. Click on Next to continue. 3. Enter your Name and Company name in the spaces provided, and then click on Next to continue. 4.

Page 23: Typical Modbus Applications
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. NPort 6110 Ethernet NPort 6110 RS-232... -
Page 24: Ethernet Master Devices Talk To Multiple Serial Slave Devices
The software configurable serial interface supports either RS-232 or RS-422/485. In RS-232/422 modes, NPort 6110 can be connected to 1 serial device. Under RS-485 mode, NPort 6110 supports up to 31 serial devices, which is the most popular application for factory floor applications. -
Page 25: Serial Master Devices Talk To Multiple Ethernet Slave Devices
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 by each NPort 6110. -

Configuring Modbus Gateway We discuss the following topics in this chapter: Starting Modbus Gateway Configurator Searching for NPort 6110 " Broadcast Search " Specify by IP Address Modify Configuration " Network Settings " Modbus Settings " Advanced Modbus Settings " Modbus Serial Settings "... -
Page 28: Starting Modbus Gateway Configurator
Starting Modbus Gateway Configurator To start Modbus Gateway Configurator, click on Start # Programs # NPort Modbus Gateway Utility # Modbus Gateway Configurator. The Modbus Gateway Configurator window will open as shown below. -
Page 29: Searching For Nport 6110
Broadcast Search is used to locate all NPort 6110s connected to the same LAN as the host, and Search by IP is used to locate a specific NPort 6110, particularly if it is located outside the LAN and can only be accessed by going through a router. -
Page 30: Modify Configuration
If the search is successful, information related to the NPort 6110 will be displayed in the Modbus Gateway Configurator window. NOTE If using the Search by IP Address function fails to locate the NPort 6110, one possible reason is that the IP address you entered to conduct the search is incorrect. -

Master types. Choose the Modbus protocol of the attached serial device to determine the complementary Modbus protocol for the NPort 6110 Modbus Gateway. Four different types of serial Modbus device can be used. Since the Modbus protocol is used on a Master-Slave network, there are two steps to consider before starting the configuration process. - Page 34 = 502 1 to 247 Notes Set the Modbus type of the serial device attached to NPort 6110’s serial port. NPort Modbus Gateway provides this setting for those PLCs that need a longer time for their system to be initialized.

except that the data format is Modbus/ASCII. 5. When the NPort Modbus Gateway receives a command from the serial port, the ID No. range table is used identify which IP address to connect to (e.g., if ID No. = 15, then according to the table in the Modbus Settings page shown above, the command is sent to the device that has IP of 192.168.127.3. - Page 36 Setting Auto Slave Unit ID Character Timeout Message Timeout Modbus/TCP Exception Additional Information 1. Modbus/TCP protocol contains a “Unit ID” field to identify multiple Modbus slave devices accessible at a single IP address. When the Modbus/TCP command contains a Unit ID, the Modbus Gateway can pass the Unit ID to Modbus serial devices.
- Page 37 when Auto Slave Unit ID is “Disabled.” 2. When the Modbus serial protocol is set to Modbus/RTU, each message packet is determined by a character timeout. An incorrect character timeout might cause a CRC checksum error. NPort Modbus Gateway allows a variable character time out setting, ranging from 10 to 3000 ms, when the attached serial device is set to Modbus/RTU.
