Hi, you can do this but to change a value via cursor keys requires to press additional the ESC key and this is normaly no what is expected. It's better to use the F-Keys of the LOGO! TD. Here an example which includes both: I hope this helps AttachmentPI via TD F-keys.zip (972 Downloads) |

Hi, look at my solution of a comfort version of key inputs: Cursor key can only used as sort puls inputs, external key can usedas long holded key inputs and so the circuit can workas auto pulser if external key is on a longer time. The input range can set by parameters and over the mux and the amplifivers the input values can scaled od translated... For your application to output a range from 0 to 1000 (for analog output modul) this can used to define Gain = 10 and so you must not input 1000 steps - then the input range is 100 steps for the hole range 0..1000.... The cirkuit at the attachment isbuilded as a complete circuit and can reduced.... I don´t know if the Fi-key can hold and then the program get a longer puls or if the Fi-kes only put a short puls to the circuit - please test it. External key replase with F-keyand in the other case cursor key replace with F-key... Best regards Betel AttachmentDEMO_TasterEingabe_eines_Wertes_aus_einem_Bereich.zip (1324 Downloads) |
