Modbus Master Controller
The X-404 module functions as a web-based Modbus master controller and monitor for third-party RS-485 modbus sensors and devices. It can monitor up to 32 modbus devices/sensors. The X-404 is also a fully-featured, web-enabled temperature and humidity module with a 1-Wire Bus that allows for monitoring up to 16 sensors.
Sensor values can be monitored over any TCP/IP network including private networks, IP-based industrial control networks, and the Internet. Users can operate the X-404 using a web browser, the CBW Mobile app, or custom applications written for a computer, PLC, or other automation controller.
The X-404’s built-in interface allows you to create custom “Tasks” for simple and advanced control logic. Create tasks based on time, or sensor status. The X-404 also has a builtin BASIC interpreter. Other features are email notification and logging. The X-404 can control and monitor up to 32 remote devices, graph logged data, FTP logged data, email logged data, send encrypted emails, and monitor its power supply voltage.
The X-404 supports a number of Ethernet protocols including: HTTP/ HTTPS, Modbus/TCP, SNMP V1,V2 & V3, NTP, SMTP (Encrypted), and FTP/FTPS. The status of the device can be retrieved in human readable formats XML and JSON. The X-404 supports TLS V1.2 encryption as well as cloud integration (not required) for easier configuration and access.
The required power supply is 9-28Vdc.
