Ethernet and World wide web Primarily based Industrial Valve Control Systems

Ethernet or World-wide-web primarily based valve handle systems are hassle-free since they allow you to access your control program at any time. They are straightforward to set up considering the fact that Ethernet cabling is now normally pre-installed in most buildings. You may well need to open or close a valve primarily based on a schedule or conditions. You can set up the valve manage program to open or close primarily based on logic or you can access the program remotely and manually open or close a valve. There are different approaches you can implement such a program.

Ethernet and Modbus TCP based valve handle 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 means of data acquisition over the Modbus TCP driver. ET-7017 has eight analog input channels and supports ±150mV, ±500mV, ±1V, ±5V, ±10V, ±20mA, ~20mA, and four~20mA input sorts. Control Valves -7017 also has 4 digital output channels that can output 5 to 50 VDC to manage a valve.

With Pc based cost-free EZ Information Logger software program, the valve handle technique 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 control logic like if AI_2 > 15mA then DO_2 = 1 which implies if analog input channel quantity two is greater than 15mA then turn digital output channel number two on. You can set up email alarms to get sent out when the tank is above a desired 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 program to log the information so you can track the level in the tank and the status of the valves for analysis.

A more advanced valve handle technique can be set up with KingView SCADA software. KingView is Pc based SCADA (Supervisory Handle and Data Acquisition) software that can be made use of to set up a handle and monitoring program. With KingView, you can add graphical animation, publish the method to the net for access more than the web, display data acquisition facts with extra sophisticated trend graphs, information logging, comparison curves, x-y charts, and implement program redundancy. It comes with an hour of cost-free net based coaching.
