Description Tank Process

This is a tank-based machine with proportional solenoid valves to fill and empty the tanks at the required speed.

In general, it uses the Tank Process UDC.

Each tank must be configured according to the following parameters:

Tank capacity (for example, 100,000 liters)

Liquid color (Red, Green, and Blue, from 0 to 1)

Initial value (Liters in the tank at machine startup, from 0 to the tank capacity)

We must configure the analog input number where we will read the level.

In addition, the analog output numbers where we will set the speeds:

Input speed Output speed

The machine has three groups of tanks:

1 Storage tanks:

We have 4 nurse tanks, that is, where the liquid is accumulated so that it can be dosed from these tanks to the dosing tanks.

 2 Weighing tanks:

We have 4 weighing tanks, where the liters of each component to be mixed are controlled.

Each weighing tank is fed by the corresponding storage tank.

All weighing tanks are destined for the mixing or mixing tank.

 3 Mixing tank:

We have a single tank where the quantities dosed in the weighing tanks are mixed.

This mixing tank has blades that mix or stir the liquid.

These blades operate automatically, meaning that when the mixing tank contains liquid, the blades rotate, while if it is empty, the blades stop.

The process is as follows:

1. Sufficient material is stored in the storage tanks.

2. The quantity of material for each liquid to be prepared is decided.

3. The weighing tanks are filled while the storage tanks are emptied at the same speed so that the liquid is transferred to the required amount in each tank.

4. As each liquid is dosed, the corresponding tank is emptied into the mixing tank.

5. Once all the weighing tanks have been emptied, the mixture is allowed to homogenize in the mixing tank.

6. After this time, the mixing tank is emptied.This machine does not use any digital signals, only analog ones.

To perform this process, we have the following analog inputs and outputs:

a. Analog Outputs:

1. Stockpile 1 Filling Speed

2.Stockpile 1 Emptying Speed

3.Stockpile 2 Filling Speed

4.Stockpile 2 Emptying Speed

5.Stockpile 3 Filling Speed

6.Stockpile 3 Emptying Speed

7.Stockpile 4 Filling Speed

8.Stockpile 4 Emptying Speed

9. Weighing 1 Filling Speed

10.Weighing 1 Emptying Speed

11.Weighing 2 Filling Speed

12.Weighing 2 Emptying Speed

13.Weighing 3 Filling Speed

14.Weighing 3 Emptying Speed

15.Weighing 4 Filling Speed

16.Weighing 4 Emptying Speed

17. Mixer Filling Speed

18. Mixer Emptying Speed

b. Analog Inputs:

1. Storage Tank Level 1

2. Storage Tank Level 2

3. Storage Tank Level 3

4. Storage Tank Level 4

5. Weighing Tank Level 1

6. Weighing Tank Level 2

7. Weighing Tank Level 3

8. Weighing Tank Level 4

9. Mixer Tank Level

By acting on each analog output, we must control the process externally.

For example, we have the demo program, created in script code in Machines Simulator, which includes data collection of the levels to be dosed from each tank, as well as a button to start loading.

Please note that the number of analog inputs must be configured in the configuration.
