1 Description
Introduction
This document describes how to route messages between Modbus RTU and Modbus TCP networks using the Intesis
Modbus RTU to Modbus TCP Router.
The aim of this integration is to make accessible data from devices in a Modbus RTU network to a Modbus TCP
network in a transparent way.
Configuration is carried out using the configuration software IntesisTM MAPS.
This document assumes that the user is familiar with Modbus technologies and their technical terms.

Functionality
After the start up process, Intesis helps route Modbus communications from a Modbus TCP to Modbus RTU
networks, allowing Modbus TCP devices to cummunicate with Modbus RTU devices present in another network.
It is not necessary to perfom any mapping as the data from one side is shown on the other side in a transparent way.
The router also has diagnostic signals available trough TCP port 503 to check that all the communication from each
side is working properly.

2 Connections
Find below information regarding the Intesis connections available.
Power Supply
Must use NEC Class 2 or Limited Power Source (LPS) and SELV rated power
supply.
Respect polarity applied of terminals (+) and (-). Be sure the voltage applied is
within the range admitted (check table below). The power supply can be connected
to earth but only through the negative terminal, never through the positive terminal.
Ethernet
Connect the cable coming from the IP network to the connector ETH of the
gateway. Use an Ethernet CAT5 cable. If communicating through the LAN of the
building, contact the network administrator and make sure traffic on the port used
is allowed through all the LAN path (check the gateway user manual for more
information). With factory settings, after powering up the gateway, DHCP will be
enabled for 30 seconds. After that time, if no IP is provided by a DHCP server, the
default IP 192.168.100.246 will be set.
Port Modbus RTU
Connect the EIA485 bus to connectors A (B+), B (A-) and SG (SNGD) of gateway’s
Port. Respect the polarity.
Note for EIA485 port; Remember the characteristics of the standard EIA485 bus:
maximum distance of 1200 meters, maximum 32 devices connected to the bus,
and in each end of the bus it must be a termination resistor of 120 Ω.
Ensure proper space for all connectors when mounted (see section 5).

Powering the device
A power supply working with any of the voltage range allowed is needed (check section 4). Once connected the RUN
led (Figure above) 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.
Connection to Modbus
2.2.1 Modbus TCP
Connect the communication cable coming from the network hub or switch to the ETH port of Intesis. The cable to be
used shall be a straight Ethernet UTP/FTP CAT5 cable.
2.2.2 Modbus RTU
Connect the communication cable coming from the Modbus network to the port marked as Modbus of Intesis.
Connect the EIA485 bus to connectors A (B+), B (A-) and SG (SGND). Respect the polarity.
Remember the characteristics of the standard EIA485 bus: maximum distance of 1200 meters, maximum 32 devices
connected to the bus, and in each end of the bus it must be a termination resistor of 120 Ω.
Connection to the configuration tool
This action allows the user to have access to configuration and monitoring of the device (more information can be
found in the configuration tool User Manual). One method to connect to the PC can be used:

Set-up procedure
1. Install Intesis MAPS on your laptop, use the setup program supplied for this and follow the instructions given by
the Installation wizard.
2. Install Intesis in the desired installation site. Installation can be on DIN rail or on a stable not vibrating surface
(DIN rail mounted inside a metallic industrial cabinet connected to ground is recommended).
3. Connect the communication cable coming from the Modbus TCP network to the port marked as Ethernet on
Intesis (More details in section 2).
4. Connect the communication cable coming from the EIA485 port of the Modbus RTU installation to the port
marked as Modbus RTU of Intesis (More details in section 2).
5. Power up Intesis. The supply voltage can be 9 to 30 Vdc. Take care of the polarity of the supply voltage applied.
WARNING! In order to avoid earth loops that can damage Intesis 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.
6. If you want to connect using IP, connect the Ethernet cable from the laptop PC to the port marked as ETH of
Intesis (More details in section 2).
7. Open Intesis MAPS, create a new project selecting a copy of the one named INMBSRTR0320000.
8. Modify the configuration as desired, save it and download the configuration file to Intesis as explained in the
Intesis MAPS user manual.
9. Visit the Diagnostic section and check that there is communication activity, some TX frames and some other RX
frames. This means that the communication with the Modbus TCP Client device/s and Modbus RTU slave
devices is OK. In case there is no communication activity between Intesis and the Modbus devices, check that
those are operative: check the baud rate, the communication cable used to connect all devices and any other
communication parameter.
