  1. TIMERS When and how to use them Dott. Ing. Alessandro Paganin - I.T.I. Malignani UDINE

  2. In process controls the timing is often really important; a stable time basis is necessary to sincronyse all the steps of signalling plants (e.g. traffic light plants) Dott. Ing. Alessandro Paganin - I.T.I. Malignani UDINE

  3. Traffic light simulation system Dott. Ing. Alessandro Paganin - I.T.I. Malignani UDINE

  4. it is sometimes possible to measure a quantity, controlling the length of time the action requires (e.g. the radius lift arm which takes the inert materials necessary to produce concrete) Dott. Ing. Alessandro Paganin - I.T.I. Malignani UDINE

  5. Radius lift arm Dott. Ing. Alessandro Paganin - I.T.I. Malignani UDINE

  6. it is sometimes necessary to verify that a certain action is over within the given time or to stop it (time out alarm) Dott. Ing. Alessandro Paganin - I.T.I. Malignani UDINE

  7. Automatic gate Dott. Ing. Alessandro Paganin - I.T.I. Malignani UDINE

  8. TIMERS are tha macro instructions available in every PLC (programmable logic controller) in order to control the processes mentioned before. Dott. Ing. Alessandro Paganin - I.T.I. Malignani UDINE

  9. S_VIMP = timer typeS = set inputTW = time constantR = reset inputT no. = timer numberQ = output timerDUAL = time missing to the end, in Binary codeDEZ = time missing to the end, in BCD code Dott. Ing. Alessandro Paganin - I.T.I. Malignani UDINE

  10. S_EVERZ = timer typeS = set inputTW = time constantR = reset inputT no. = timer numberQ = output timerDUAL = time missing to the end, in Binary codeDEZ = time missing to the end, in BCD code Dott. Ing. Alessandro Paganin - I.T.I. Malignani UDINE

  11. S_SEVERZ = timer typeS = set inputTW = time constantR = reset inputT no. = timer numberQ = output timerDUAL = time missing to the end, in Binary codeDEZ = time missing to the end, in BCD code Dott. Ing. Alessandro Paganin - I.T.I. Malignani UDINE

  12. S_AVERZ = timer typeS = set inputTW = time constantR = reset inputT no. = timer numberQ = output timerDUAL = time missing to the end, in Binary codeDEZ = time missing to the end, in BCD code Dott. Ing. Alessandro Paganin - I.T.I. Malignani UDINE
