Numerics

Publication 2711E-820 – January 1998

When a Numeric Input Cursor Point is selected, the Numeric Entry
scratchpad prompt

“Enter New Value

or Press Cancel”

appears on the top of the display. The operator then uses the Numeric
Keypad keys to type the new value, and presses the Enter key to send
the value to the Keypad Numeric Input control. If you assign the
Optional Keypad Write Expression, the PanelView terminal can
perform a mathematical calculation or logical operation on the value
the operator enters, and then send the result to the PLC.

If the operator uses the Raise or Lower keys while the scratchpad’s
value field is blank, the Keypad Numeric Input control value is
incremented or decremented directly, without the Enter key being
pressed. The Raise and Lower keys are disabled as soon as a digit is
entered into the Numeric Entry scratchpad. They remain disabled
until the value in the scratchpad has been entered or cleared.

Note: If you assign the Optional Keypad Write Expression, the
Raise and Lower keys are disabled.

The operator can enter up to 16 digits in the window. By default, 5 of
these are displayed. Pressing Enter validates the value. If the value
entered is valid, the window clears. The new value is then sent to the
PLC.

If the value is invalid, an error message appears. The value remains
in the window and is not sent to the PLC. The operator must clear
the error message from the display.

Note: The Numeric Entry scratchpad occupies the full screen width
of the top 60 pixels of the screen. When displayed, the scratchpad
covers any objects in this area. Keep this in mind before you place
objects in this area.

Important:

In Remote I/O applications, the PanelView terminal can
retain the current values for the object’s controls, even
after the terminal is turned off. Depending on how the
Application Startup operation is defined, the retained
value (last state) or initial value (default) is sent to the
PLC when power is re-applied.

For details on configuring Application Startup
operation, see “Application Startup” in Chapter 4 in the
PanelView 1200e and 1400e Operator Terminals User
Manual.
