Product Description
The ETPort module is a Modbus/RTU to Ethernet & WiFi gateway featuring multiple simultaneous modes of operation. It is an ideal accessory for WattsOn-Mark II devices, as well as any other RS-485, Modbus/RTU slaves.
The ETPort allows instantaneous, real-time register access via its on-board web interface, transparent Modbus/TCP to Modbus/RTU bridging, and the ability to post Modbus Register data to cloud servers via a highly flexibly template structure.
Utilizing the on-board JumpBus header, the ETPort may be instantly connected to the WattsOn-Mark II, sharing the power supply and making data connections to the meter. This relieves the need for additional wiring.
The ETPort provides a dynamic AJAX-enabled web interface. It allows easy addition of multiple Modbus/RTU devices and registers, as well as virtual points which allow the user to specify math operations (add, subtract, multiply, divide) on multiple device registers. The ETPort may send device data to a web server via HTTP(S) POST at regular intervals, using a highly configurable template-based format.
The additional RS-485 terminal provides a pass-through interface allowing for simultaneous communication from RS-485 Modbus/RTU Masters and Modbus/TCP clients via Ethernet or WiFi.
