Ethernet or World wide web primarily based valve manage systems are easy due to the fact they let you to access your manage program at any time. They are uncomplicated to set up given that Ethernet cabling is now commonly pre-installed in most buildings. You may possibly require to open or close a valve primarily based on a schedule or circumstances. You can set up the valve control program to open or close primarily based on logic or you can access the method remotely and manually open or close a valve. There are diverse approaches you can implement such a program.

Ethernet and Modbus TCP based valve manage devices like ET-7017 can take a 4-20mA measurement from a float sensor in a tank and output 40 VDC to manage a valve. ET-7017 can bring the level of the tank into the valve manage system by way of data acquisition more than the Modbus TCP driver. ET-7017 has eight analog input channels and supports ±150mV, ±500mV, ±1V, ±5V, ±10V, ±20mA, ~20mA, and four~20mA input types. ET-7017 also has 4 digital output channels that can output five to 50 VDC to control a valve.

With htvietnamvalve based no cost EZ Information Logger application, the valve manage method can be set up such that the valve can open or close primarily based on the level of the tank. EZ Information Logger supports VB Script so you can implement manage logic like if AI_two > 15mA then DO_2 = 1 which implies if analog input channel number two is higher than 15mA then turn digital output channel quantity two on. You can set up email alarms to get sent out when the tank is above a preferred variety. You can also set up buttons that you can click which can manually turn the valves on or off. You can set up bar graphs that can show you the level in a tank. With EZ Data Logger you can also set up trend graphs. You can also set up the technique to log the data so you can track the level in the tank and the status of the valves for evaluation.

A far more sophisticated valve manage method can be set up with KingView SCADA application. KingView is Pc based SCADA (Supervisory Manage and Information Acquisition) software that can be utilized to set up a manage and monitoring system. With KingView, you can add graphical animation, publish the technique to the internet for access over the world-wide-web, show information acquisition information and facts with a lot more advanced trend graphs, information logging, comparison curves, x-y charts, and implement method redundancy. It comes with an hour of absolutely free internet primarily based training.
