Objective: Add three components to the container. The amount of each component is set by the operator at the beginning of the batching cycle. I don't understand how to keep the amount of one component without affecting the others. To move through the components, I use the left-right arrows, and to select the dose of each up and down. How do I keep the selected value when switching to another component?

I am sending the source for now, figured out how to save the values of the counters. But now another challenge is how to use the TDE arrow buttons without pressing ESC.

Each of the component is dosed by individual dosing pump. The system can be operated in two modes: 1. Automatic. The pumps are to be operated by LOGO in the following mode: The authorized personell sets the required dose of each component in KG from a TDE screen/ The operator presses START by external contact. LOGO converts the required dose into dosing time, using a correction coefficient K (K1, K2, K3 individual for each component and set in the program) and starts timer 1 (to operate dosing pump 1), than timer 2 and 3. The delays (t1, t2,t3) befor start, between timers 1 ,2 and timers 2and 3 should be also programmed. So we have 3 sets of variables: Doses (D1, D2 and D3), correction coefficients (K1, K2, K3) and delay times (D1, D2, D3). These parameter can be changed 2. Manual. Operator can add a required dose of any component, setting values D1x, D2x and D3x. Values D1, D2 ,D3, K1, K2, K3, t1, t2, t3 can be changed only by authorized personell (using a password) Values D1x, D2x, D3x can be set by an operator. Modes are selected by an externa selector. A program is started by external START button and can be PAUSED/RESUMED by this BUTTON. A program can be stoped at any time by an external STOP button.

I solved this problem, but now I cannot solve the problem of using arrows on TDE, without pressing ESC ...
