Q: If you change the preset while the timer is running will it affect the timer?
A: Nice Question! No, it will not! In fact when you start the timer, it loads the preset value to current register and then it counts down to zero. If you will change the preset value, it will be loaded on the next start.

Q: If there are multiple screens, let’s say 8, how can you jump from 1 to 7 to 3 to 8? Is scroll though the only way?
A: Under each screen you can define many conditions to jump. So – pressing one “button” – you jump to display 2, with another condition you can jump to another display… In addition, you can add jump conditions in ladder.

Q: When the operator changes the timer (Keypad Entry) on a HMI. In a new HMI, I have set the display timer “Elapsed Time” does not update the value that the operator changes. Shows the old value. Why?
A: The Current value is updated in the moment the timer starts to run! You will not see updated Preset value in Current mode until the timer starts running

Q: I tried using the same MB to jump to a new screen and to simultaneously perform another function (programmed in the ladder). Does not work. This wrong?
A: I don’t know what exactly you did in ladder. In general, when you define MB as “touch”, it starts to operate as “hardware”. If you use it for jump, it operates as positive transition.
