Module I/O Web-based Ethernet MQTT ICP DAS MQ-7200M


The MQ-7200M series is a web-based Ethernet I/O module equipped with a built-in web server allows the user to configure module and control/monitor the status of digital I/O by simply using a regular web browser. Support for MQTT protocol makes it easy to connect sensors to Industrial Internet of Things (IIoT) system via the MQ-7200M series module. Users can simply and effectively control/monitor remote sensors with MQTT client tools on the PC/NB or mobile devices.

1. Support for MQTT Protocol

MQTT stands for Message Queuing Telemetry Transport. It is a machine-to-machine (M2M)/”Internet of Things” connectivity protocol with extremely lightweight publish/subscribe messaging transport. It is useful for mobile applications because of its small size, low power usage, minimized data packets, and efficient distribution of information to one or many receivers.

2. Built-in I/O

Various I/O components are mixed with multiple channels in a single I/O module, which provides the most cost effective I/O usage and enhances performance of the I/O operations.

3. Daisy-Chain Ethernet Cabling

The MQ-7200M Series has a built-in two-port Ethernet switch to implement daisy-chain topology. The cabling is much easier and total costs of cable and switch are significantly reduced.

4. LAN Bypass
LAN Bypass feature guarantees the Ethernet communication. It will automatically active to continue the network traffic if any one of the MQ-7200M looses its power.

5. Dual Watchdog

The Dual Watchdog is consists of a Module Watchdog and a Communication Watchdog. The actions of digital output are also associated to the Dual Watchdog.
Module Watchdog is a built-in hardware circuit to monitor the operation of the module and will reset the CPU if a failure occurs in the hardware or the software. Then the Power-on Value of digital output will be loaded.
Communication Watchdog is a software function to monitor the communication between the MQTT broker and the MQ-7200M. When the MQ-7200M is disconnected from the MQTT broker for a while, the watchdog forces the digital output to pre-defined Safe Value to prevent unpredictable damage of the connected devices.

6. Highly Reliable Under Harsh Environment

Wide Operating Temperature Range: -25 ~ +75°C
Storage Temperature: -30 ~ +80°C
Humidity 10 ~ 90% RH (Non-condensing)

7. Power-on Value and Safe Value

Power-on value and Safe Value are designed to improve system safety:
Power-on Value: The Power-on Value is loaded into the digital output when the module is powered on or reset by Module Watchdog.
Safe Value: When the Communication Watchdog is enabled and a Communication Watchdog timeout occurs, the “safe value” is loaded into the digital output.

8. LED indicators for DIO status

The LED indicators are used to indicate the status of digital I/O on the MQ-7200M.

9. Two pair of power input pins

The MQ-7200M has 4 pins as two pairs for power input to ease the wiring.
