port that can connect to many types of Modbus device. By translating Modbus/TCP (Ethernet) and Modbus/ASCII/RTU (Serial) protocols, a PLC with Ethernet can use the RS-232/485 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

Plug the power adapter’s DC plug into NPort 6110’s DC-IN jack. 2. Plug the power adapter into an electrical outlet. Note that there is no on/off switch. NPort 6110 automatically turns on when plugged into the outlet, and the red PWR

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. In this case, use a regular straight-through Ethernet cable. 2. When configuring NPort 6110, you may connect NPort 6110 directly to your computer’s Ethernet connector. To

Housing DIN-Rail For many industrial applications, you will find it convenient to use the DIN-Rail attachments, as shown below. STEP 1: Use 2 screws per ear to attach DIN-Rail mounts to each of NPort 6110’s two ears. ⇒ STEP 2: Insert the top of the DIN-Rail STEP 3: Push the bottom of NPort into the top slot of the 6110 so that the bottom of the DIN-Rail mount. DIN-Rail snaps into DIN-Rail mount’s bottom slot. NOTE: The DIN-Rail mounting kit is an optional accessory. To remove

Wall Mount For many industrial applications, you will find it convenient to mount NPort 6110 on the wall, using two screws, as indicated below. STEP 1: Screw two screws, separated by 7.8 cm, into the wall. The heads of the screws should be no greater than 6.5 mm in diameter, and the shafts should be no greater than 3 mm in diameter. Do not screw the screws in all the way—leave a space of about 2 mm to allow room for sliding the NPort 6110 unit’s ears between the wall and the screws.

3 3 3.Typical Modbus Applications In this chapter, we introduce three typical Modbus 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, provided the transmission distance does not exceed 1.2 km. By using Modbus Gateway, you can link all Serial Modbus device

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 R
