1. Description

1.1 Introduction

Communicate with Modbus RTU slaves remotely using Modbus TCP, with the advantage of

having various Modbus TCP masters accessing the same RTU slaves simultaneously.

Transparent operation: the Modbus TCP telegrams are converted to Modbus RTU and vice-

versa transparently.

When more than one Modbus TCP master is connected, the queries of each master are

appropriately alternated, handling the waiting queues and RTU bus access.

Simple configuration: only the IP address, Net Mask, EIA232 or EIA485, baud rate, parity

and stop bits are needed. All is done using LinkBoxMB software for windows, provided with

the gateway without additional cost, quickly and easily.

The Modbus TCP port acts as a slave, the Modbus RTU port acts as a master.

1.2 Functionality

This gateway allows communicating with Modbus RTU slave devices from any Modbus TCP

master. The gateway behaves as a Modbus TCP slave device.

The procedure of configuration of IntesisBox is as simple as following these steps:

-Introduction of the communication parameters for Modbus ports

-Once this configuration has been done with the configuration software tool

LinkBoxMB, you have to download this configuration to IntesisBox via a serial or

Ethernet connection and IntesisBox will reboot with the new configuration working.

1.3 Capacity of IntesisBox

Element

Max.

Notes

Number of TCP masters

IntesisBox can handle up to 32 TCP Masters, all of

them connected to the same Ethernet port.

Number of RTU slaves

321

IntesisBox can handle up to 32 Modbus slave

devices

Ref.: IBOX-MBS-TCP2RTU

2. Modbus interfaces of IntesisBox

2.1 Modbus TCP

IntesisBox Modbus TCP communication uses the Ethernet port of the gateway with standard

Ethernet configuration.

2.2 Modbus RTU

IntesisBox Modbus RTU communication can work with both EIA232 and EIA485. The baud

rate, parity and polling time can be configured.

IntesisBox could handle up to 255, but it is strongly recommended not use more than 32 RTU slave devices to

avoid communication problems and to ensure integration stability.

3. Quick Setup

1. Install LinkBoxMB Details in section 5

2. Install IntesisBox in the desired installation site (DIN rail mounting inside a metallic

industrial cabinet connected to ground is recommended).

3. Power up and connect the communication cables. Details in section 4

4. Open LinkBoxMB, open a project or create a new one. Details in section 5.

5. Connect to the IntesisBox (details in section 5)

6. (optional) Configure the IntesisBox. Details in section 5.1

7. Check if there is communication in both Modbus TCP and Modbus buses (section 5).

8. The IntesisBox is ready to be used in your system.

4. Connection

The device uses a standard enclosure allowing DIN EN60715 TH35 rail mounting. Its plastic

meets standard PC UL 94 V0.

Figure 4.1 Device connection diagram

Ensure proper space for all connectors when mounted.

The items supplied by Intesis Software for this integration are:

IntesisBox Modbus Server –Modbus RTU hardware

Console cable. Standard DB9F-DB9M cable 1.8 meter long.

Installation sheet, containing a link to the LinkBoxMB software and this manual.

Console wire 1.8 m long.

4.1 Power device

The first step to perform is to power up the device. To do so a power supply working with

any of the voltage range allowed is needed (check section 6). Once connected the ON led

will turn on.

WARNING! In order to avoid earth loops that can damage the gateway and/or any other

equipment connected to it, we strongly recommend:

The use of DC power supplies, floating or with the negative terminal connected to

earth. Never use a DC power supply with the positive terminal connected

to earth.

The use of AC power supplies only if they are floating and not powering any other

device.

4.2 Connect to Modbus RTU

Connect the communication cable coming from the Modbus RTU network to the port marked

as Modbus RTU of IntesisBox (Figure 4.1). Two methods to connect to the Modbus network

can be used:

The EIA485 port if the network is EIA485 2-wire. Connect the + and the –to the

respective ports in the slave devices (polarity matters)

The EIA232 port if the connection is point to point to one single slave.

How to check if there is communication with the Modbus bus is explained in the LinkBoxMB

Manual (section 5).

4.3 Connect to Modbus TCP

Connect the communication cable coming from the network hub or switch to the ETH port

(Figure 4.1) of IntesisBox. The cable to be used depends on where the IntesisBox is being

connected:

Connecting directly to a Modbus TCP master device: crossover Ethernet UTP/FTP

CAT5 cable

Connecting to a hub or switch of the LAN of the building: a straight Ethernet UTP/FTP

CAT5 cable

Check your Modbus device’s user’s manual provided by its respective manufacturer to know more details about pin out.

In case there is no communication with the IntesisBox IntesisBox, check that the Modbus

TCP devices they are operative and reachable from the network connection used by

IntesisBox. Check the IntesisBox Ethernet interface sending Pings to its IP address using a

PC connected to the same Ethernet network.

4.4 Connect to PC (LinkBoxMB)

This action allows the user to have access to configuration and monitoring of the device

(more information can be found in the LinkBoxMB User Manual [section 5]).Two methods to

connect to the PC can be used:

Ethernet: Using the ETH port (Figure 4.1) of IntesisBox. How to check connectivity is

explained in section 4.3.

Serial cable: To connect the device to the PC the serial cable supplied should be

plugged to the PC console port (Figure 4.1).

The cable is an EIA232 straight cable and its pin out is at explained in Table 4.2.
