8-ch Digital Input IoT Wireless I/O WISE-4051 Module with RS-485 Port Features 8-ch digital input with 1-port RS-485 for Modbus devices 2.4GHz Wi-Fi reducing the wiring cost during big data acquisition Easily extend the existing network by adding APs, and share existing Ethernet software Configured by mobile devices directly without installing any software or Apps Zero data loss using the log function with RTC time stamp Data can be automatically pushed to Dropbox or computer Supports RESTful web API in JSON format for IoT integration RESTful Web Service with Security Socket Introduction As well as supporting Modbus/TCP, the WISE-4051 series also supports IoT communication The WISE-4051 is an Ethernet-based wireless IoT device, integrated with IoT data protocol, RESTful web service. Data can be polled or even be pushed automatically from acquisition, processing, and publishing functions. As well as various I/O types, the WISE- the WISE-4051 when the I/O status is changed. The I/O status can be retrieved over the 4051 provides data pre-scaling, data logic, and data logger functions. Data can be accessed web using JSON. The WISE-4051 also supports HTTPS which has security that can be via mobile devices and be securely published to the cloud anytime from anywhere. used in a Wide Area Network (WAN). Features IEEE 802.11 b/g/n 2.4GHz Wi-Fi with AP Mode The Wi-Fi interface is easily integrated with wired or wireless Ethernet devices, users only need to add a wireless router or AP to extend existing Ethernet network to wireless. The limited AP mode enables the WISE-4000 to be accessed via other Wi-Fi devices directly as an AP. Data Storage The WISE-4000 can log up to 10,000 samples of data with a time stamp. The I/O data can be logged periodically, and also when the I/O status changes. Once the memory is full, users can choose to overwrite the old data to ring log or just stop the log function. Modbus/RTU to Web Service or Modbus/TCP The RS-485 port of the WISE-4051 supports Modbus, which can be used to poll the data from Modbus/RTU devices, like ADAM-4000, or ADAM- 5000/485. Then you can access the data by Modbus or REST from the WISE-4051. The data can also be logged. Cloud Storage Data logger can push the data to file-based cloud services like Dropbox using pre-configured criteria. With RESTful API, the data can also been pushed to a private cloud server in the format of JSON. Users can setup their private cloud server using the provided RESTful API and their own platform.
