Module 2 cổng Ethernet Modbus TCP 16 kênh đầu ra số DO Sink-type ICP DAS ET-2242U CR

Providing various digital I/O functions, the ET-2242U module is an Ethernet I/O monitoring and control module. The module can be remotely controlled through a 10/100 M Ethernet network by using Modbus TCP/UDP protocol. Modbus has become a de facto standard communications protocol in industry and is now the most commonly available means of connecting industrial electronic devices. This makes the ET-2242U module perfect integration with the HMI, SCADA, PLC, and other software systems.

The ET-2242U provides 16 sink- or source-type digital output channels by wire connection and each channel can drive a 500 mA load. There are configurable power-on and safe values for digital output. With 2 Ethernet ports, the ET-2242U allows a daisy chain connection which permits flexibility in locating devices, eases installation, and lowers infrastructure costs. It features 8 kV ESD protection, 4 kV EFT protection, 3 kV surge, and 3000 VDC I/O isolation are also provided to enhance noise protection capabilities in industrial environments.

The module can be used to create DI to DO pair-connect through the Ethernet. After configuration, the ET-2242U module can poll the status of remote DI channels via the Modbus TCP protocol and write data to local DO channels.

It is equipped with a removable terminal block connector for easy and robust wiring in industrial situations and features a powerful 32-bit ARM MCU to handle efficient network trafficking.

ET-2242U module supports MQTT protocol and can act as a message publisher and subscriber. After connecting to the server MQTT Broker, the I/O status of the module can be published in the form of a topic, and can also receive messages from the same subscription topics. In communication, when the ET-2242U module is disconnected from the broker, the module has a reconnection mechanism that can automatically reconnect with the broker. In addition, there is a Keep-Alive Interval mechanism to ensure that the connection with the Broker is always maintained.

The ET-2242U supports the standard SNMP V2c specification. Through this specification, ET-2200 can transmit module information and I/O information to SNMP network management equipment or software (SNMP Network Management Software) to help administrators monitor the status of ET-2242U in real time. If the Trap function is enabled, when the module I/O status changes or reboots, it can send a message to the manager to keep track of the channel status at any time.
