1 Introduction
1.1 Overview
The Modbus Gateway is an interface between Modbus Gateway and computer hosts running
Modbus/TCP on Ethernet networks. Fully compliant with Modbus/TCP, the Modbus Gateway offers a
convenient solution to connect existing devices or controllers running Modbus serial protocol
(Modbus/ASCII or Modbus/RTU) to an Ethernet network. The SC10E4IM Series are standard Modbus
Isolated gateways that convert between Modbus TCP and Modbus RTU/ASCII protocols.
The SC10E4IM Series support 16 simultaneous TCP master and 32 simultaneous requests for each
TCP master. Each RS-422/485 serial port can be individually configured for Modbus RTU or Modbus
ASCII operation or even different baud rate, allowing both types of networks to be fully integrated with
Modbus TCP within one package.

3 Configuration and Setup
3.1 Locating and IP configuring using Utility
First, please install our configuration utility program that comes with the Product CD. For more
information on how to install, please refer to the manual that comes in the utility CD. To find the Modbus
Gateway device on your network, press “Scan”, a list of devices currently connected to the network will
be shown in the window.

3.2 Configuration using Web Interface
Every SC10E4IM Modbus Gateway device is equipped with a built-in Web server in the firmware.
Therefore, it can be accessed by using a browser for configuration by entering the device’s IP (see Sec.
2.4 for default value).

3.2.1Configure Automatic IP Assignment with DHCP
A DHCP server can automatically assign addresses to LAN1 or LAN2, the Subnet Mask, and the
Gateway. You can simply check “DHCP” box in the Network Setting dialog using our Utility and then
restart it; once restarted it will be automatically configured.
3.3 Web Overview
In this section, only current information on the device’s status and settings will be displayed.
Fig. 3. 3
Model Name as its name implies, shows the device’s model.
Device Information displays information on the Kernel version, as well as the AP
Network Information here you may find the Mode in which the device is currently working on
(Dual Subnet, Redundancy Mode), and both LANs respective MAC and IP addresses.
Dual Subnet Mode: in which two Ethernet ports have separate IP addresses and subnets
Redundancy Mode: the system will just use one port for data transfer, if this port is
disconnected, the whole system will change to another port automatically.

3.4 Network Configuration
In this section, IP, Subnet Mask and overall connectivity settings can be accessed. When on
Redundancy Mode the device will have the two LAN ports connected1to the Network, but the signal
will flow through one of them. In the case one line is out due to any reason there will still be another
route so the signal can keep flowing.
Fig. 3. 4
Note1: you can still connect only one LAN port to the device, though you can still change the settings in it, there won’t be a
Redundancy function.

When the device is set on Dual Subnet Mode, a set of two IP addresses can be used without having
Redundancy. This is especially useful when using two different networks.

3.5.2Operation Mode
RTU Slave: when working as a slave node, the device will wait and accept request from its
master; data transfer is done under an RTU format.
RTU Master: when working as a master node, the device will issue commands to the slave node;
data transfer is under an RTU format.
ASCII Slave: when working as a slave node, the device will wait and accept request from its own
master; data transfer is under an ASCII format.
ASCII Master: when working as a master node, the device will issue commands to the slave
node; data transfer is under an ASCII format.
3.5.3Serial Settings
This section has the following selections:
RS-422/RS-485 Software Selectable (Default: RS-485)
Baud-rate: 110 bps ~ 921600 bps
Parity: None, Even, Odd, Mark, or Space
Data Bits: 5, 6, 7, or 8
Stop Bits: 1 or 2
Flow Control: None, Hardware CTS/RTS, Software Xon/Xoff
Apply to all Serial Ports Alternatively, the settings can be chosen to apply to all Serial Ports if needed
by checking the last box on the options.

3.5.4VCOM Settings
Generates a virtual Serial (COM) port within the device by the network connection, it is a TCP
connection but the encoding is an SAN’s exclusive private protocol. There is the choice to set your
device as either a Master or a Slave in your network.
You will need a VCOM setting, proceed to go to Basic Settings →VCOM Settings and tick on the
VCOM’s “Enable”box to allow configuration on the port selected.
The options for Master are similar, the only difference being on the device’s function.
Fig. 3. 7
Choose whether your device conforms as an RTU or ASCII, which is the VCOM Mode.
VCOM Port Using the TCP, the device listens whether there are any clients (VCOM clients),
connecting (Serial-IP) to its ports.
VCOM Mode Its definition is analogous to the one in Sec. 3.5.2.
Note: Windows has its own restrictive Serial-IP software installed for use.

VCOM inactivity’s Time Out can be set as well (which is the period of time allowed between
actions), with a maximum of 600 minutes or 10 hours. If no action has been taken after this period,
VCOM connection will be automatically interrupted by the system.
It is important to note that alternatively, these settings can be chosen to be applied to All VCOMs if
needed by checking the last box on the options.

3.5.5TCP Settings
Settings for representing a Modbus TCP connection using the internet are set here. First go to Basic
Settings ↔ TCP Settings, then proceed to choose whether to enable TCP ticking on the “Enable”
box.
Fig. 3. 10
TCP Slave: When on this mode, the device will run on Slave mode and wait to receive Modbus
requests from the Master; data transmission is done under a Modbus TCP format.
Remote IP Address shows the device’s slave node IP address.
TCP Port shows the device’s slave node TCP port.
VCOM inactivity’s Time Out can be set as well (which is the period of time allowed between
actions), with a maximum of 600 minutes or 10 hours. If no action has been taken after this period,
Modbus TCP connection will be automatically terminated by the system.

On Operation Mode choose whether the device is going to be a Slave or a Master. Remote IP Address
refers to the IP belonging to the device that is going to be controlled from SC10E4IM ; this option is not
available when the device is set as a Master. TCP Port is the port through which the signal is going to
be relayed upon. And again, there is a TCP Inactivity Time Out with the same 10 hours maximum value
as stated on the last section. Configuration can be saved as well.

3.5.6Slave ID Map
The system uses the Modbus ID to route Modbus’request commands (from the master node) to the
respective slave node; it is paramount to define ID maps for each slave node. For every slave node,
there must be a correct Virtual ID (Alias ID) and Real ID defined in the maps.
Offset mode can be used when device IDs to be mapped for Modbus master and slaves are
sequential whereas Alias mode can be used when Modbus master and slave IDs are not in
sequence .

Slave Interface
When a port is set to slave mode, a Slave interface will be then created for you. Select the Slave
Interface, which is the COM/VCOM/TCP port; then select Alias Mode or Offset Mode to modify the
range and offset as you needed.
Alias Mode maps a virtual ID to a real ID each at the time.
Alias ID which refers to a Virtual ID for the reading Master node.
Real ID which is the real ID from the slave node.
Offset Mode which refers to a range of defined ID maps.
Slave ID Start Virtual ID’s start number.
Slave ID End Virtual ID’s end number.
Slave ID Offset Real ID range, which is from (Slave ID Start -Offset) to (Slave ID End-Offset).
Fig. 3. 13
Note: on VCOM, TCP and COM, Master and Slave IDs can be set, while on COM and VCOM work only with Serial ports.
