If the PanelView terminal does not receive acknowledgement
(transition from 0 to 1) within 4 seconds, it displays a Minor Fault
message in the Fault Window and resets the Enter bit. If the Enter
Key Handshake is unassigned, the Enter bit will remain set for as
long as the button is pressed or for the duration of the button hold
time, whichever is longer.
IMPORTANT: When the Raise or Lower button is pressed, PanelView
sets the Enter Key Control bit (after a 400 ms delay) and ignores the Enter
Key Handshake bit. After the button is released, PanelView delays 400 ms
and then monitors the Enter Key Handshake bit for a false to true
transition. If the Enter Key Handshake bit is already set to 1 when the
Raise or Lower Button is released, the minor fault will occur if the bit does
not make another transition within 4 seconds.
IMPORTANT: All function keys are disabled while the terminal is
waiting for handshake acknowledgement.
Display opens a menu with two items:
Displayed Value Address—opens an address definition window.
If you have not defined the Enter Key Control and Enter Key
Handshake addresses, you can enter the same input address
assigned to the Keypad Numeric Input. Whatever value appears in
that address will be displayed.
If you are using the Enter Key Control And Enter Key Handshake
addresses, you must assign an output address to have the value
transferred to the terminal and displayed in the Numeric Input
Cursor Point. Program your PLC to read the value at the Keypad
Numeric Input Address and copy it to the Displayed Value
Address.
Decimal Point Position Address—this option is linked to the
Format option in the Object menu. If you chose PLC Controlled as
the decimal point format for your Numeric Input under Format,
you must assign a Decimal Point Position Address, a PLC input or
output address. This three-bit binary code indicates the number of
digits to the right of the decimal.
Program your PLC to transfer the value from the Decimal Point
Position Address assigned to the Numeric Input into the address
assigned here.
