2 Introduction

1. Overview

The ModGate Plus devices are designed to connect serial connection lines running Modbus protocol

to networks running Modbus/TCP. The network interface of ModGate Plus is implemented as Fast

Ethernet 10/100 Mbit/s. The ModGate Plus Gateways are also available with a second network

interface as WLAN (802.11b/g/n), this will be used in parallel with the standard Ethernet.

The network transport is implemented via TCP/IP protocol. Therefore control is available via

WLAN, Ethernet, Intranet and Internet. The serial data transmission uses Modbus/RTU and

Modbus/ASCII, physical on RS232 and RS485 connection lines. As an extension to the standard

RS422 is also available.

2. Introduction

This manual covers several models of ModGate Plus devices, in particular the ModGate Plus 113.

In general the operation is the same on all models, except where explicitly noted otherwise.

The devices come with a steel case well suited for industrial environments. The models provide

one, two, four and eight serial ports. Power-over-Ethernet may be ordered on the four and eight

port models.

The ModGate Plus Gateways support serial speed up to 115200 bps, which is a restriction of

Modbus. In RS232 mode the technical limit is 1000 kbps, used as RS485 the serial port can

operate up to 3 Mbps. In RS485 mode the serial ports use the Automatic Receive Transmit (ART)

control logic to follow the RS485 speciﬁcations for transmitting data.

2.1. Features

•Single power supply

DC 9-54V, 300-500 mA@12V

•Wireless LAN 802.11b/g/n (optional with integrated module or USB expansion)

•Ethernet 10/100BaseT/Auto-MDI(X) for auto-conﬁguration

•Serial port interfaces: RS232, RS422 and RS485

•Max. 115.200 bps, half- and full-duplex

•TCP/IP conﬁguration ﬁxed or by DHCP

•Easy remote conﬁguration via HTTP (browser)
