Real-time refresh for 4 serial ports and strong loading capacity.
Bridge mode support for PLC data collection without affecting PLC and HMI communication.
Watchdog function with adjustable time, IAP download for firmware updates, and one-button reset for factory settings.
35mm standard rail installation and compliance with EN 55022:2010 & EN55024:2010 standards.

Technical Parameters
Environmental parameters include a working temperature range of -40 to 85℃ and storage temperature range of -55 to 125℃. The device supports a working humidity of 5% to 95% (non-condensing). Power input is 9-36V DC with a maximum power consumption of 200mA at 24V. Ethernet parameters include two RJ45 ports with 10M/100M adaptive rate and support for ETHERNET, ARP, IP, TCP, ICMP, and MQTT protocols. The device supports up to 5 TCP connections and 4 serial ports with various communication modes and baud rates.

Hardware Description
The device features a 16Pin 3.81mm pitch plug-in terminal block for RS485/RS232/RS422 interfaces. It includes 6 LED status indicators for power, network, and communication status. The RS232/RS422 dial setting allows configuration for different communication interfaces. A system reset button is available for restoring factory settings.

Usage Instructions
The gateway's serial ports can operate in General or Bridge mode for data collection. Ethernet ports support Modbus TCP and MQTT publish channels. Configuration involves setting up the software interface, creating projects, and configuring information bars for data collection and network communication.

Modbus TCP Publish Channel

The data area includes 4K (bit) DO (Coil), DI (Discrete Input), and 1K AO (Hold Register) and AI (Input Register) for storing acquired data.
Users can configure the Modbus publish channel to set up a Modbus server, allowing data exchange with up to 5 clients simultaneously.

MQTT Publish Channel

MQTT is used for lightweight publish/subscribe message transmission, supporting various cloud platforms.
The gateway supports 10 themes and up to 50 data points per theme, with options for binary and JSON message formats.

Configuring Software Usage

Instructions for using "Odot Configuration Software" to scan and configure IoT gateways on the network.
Details on setting network and serial port parameters, including IP address, baud rate, parity, and stop bits.
Guidance on adding collection channels and configuring collection points with parameters like register area, start address, and data type.

Publish Channel Configuration

Steps for configuring Modbus TCP and MQTT channels, including setting parameters like port, connection mode, and encryption.
Instructions for adding publish points and configuring parameters such as topic name, QoS level, and data format.

Configuration Management

Procedures for downloading, uploading, importing, and exporting configurations.
Emphasis on ensuring the computer and gateway are on the same network segment for successful configuration.

IP Address Modification

Steps for changing the gateway's IP address and ensuring network compatibility.
Instructions for updating configuration software settings to reflect new IP addresses.

Test Application for Collecting SIEMENS S7-200/200 Smart PLC Data

Details on implementing PPI Protocol to Modbus TCP data exchange.
Configuration steps for Smart 200 PLC and MG-IOT01 gateway.

PLC Configurations

Smart 200 PLC: Connect using RS485, set parameters, and configure channels for Modbus TCP.
Mitsubishi FX Series PLC: Connect using RS422, set parameters, and configure for Modbus TCP and MQTT.
Omron PLC: Connect using CP1W-CIF11 in RS485 mode, set parameters, and configure for Modbus TCP and MQTT.
Delta PLC: Connect using RS232, set parameters, and configure for Modbus TCP.

Key Points

Default IP address for the IoT gateway is 192.168.1.254.
Modbus TCP communication port is 502.
MQTT server IP is 192.168.1.50 with port number 1883.
Ensure all configurations are downloaded to the gateway for successful data exchange.

Implementing Modbus RTU Protocol to MQTT Data Exchange
Configuration involves using "Odot Configuration Software" to search for devices on the local network. The default IP address is 192.168.1.254, and the PLC is connected to serial port 1 with specific parameters set for communication. The collection channel uses ASCII encoding with a slave ID of 1. A manual addition of the MQTT channel is required, with the port number set to 1883 and the server IP as 192.168.1.50. After configuring collection and publishing points, the settings are downloaded to the gateway for data publishing.

Appendix
Detailed wiring instructions for various PLCs including Siemens S7-200/200 SMART, Mitsubishi FX series, Omron series, and Delta DVP series are provided, specifying terminal connections and necessary adjustments for communication.
