Reminder
A page consists of text and fields. A field may correspond to values which have to be filled in (write) or modified (read/write) by the user or to values written by the PLC.
Ex.
Text Temperature = Field
Entry request
By the operator
Entry mode is accessed with the MOD key.
By the PLC
The PLC writes the number of the field in the word "Field to enter" in the dialog table.
Entry principle
- If the field contains more than 1 digit, the digit to be entered is displayed in steady mode, whilst the other digits blink.
- If the field contains 1 digit, the digit to enter blinks.
- The LEDs of the arrow keys blink. Note : when the LEDs are off, the corresponding keys are inactive.
Entry via numeric keypad
Keys 0 to 9 and +/- (toggle function, + is the default sign) are used to enter data.
- Select the digit to be entered using the arrow keys.
- Enter this digit, the following digit (to the right) stops blinking.
