15 ASCII Inputs
Publication 2711E-6.15 – November 1998
Field Meaning
Control The ASCII Input object uses the following controls.
ASCII Input identifies which PLC location the string will be
written to.
Note: This must be a string tag.
Enter Key Control and Enter Key Handshake must be used
together to provide handshaking between the PLC and the
terminal. You can assign a tag only to the Enter Key Control.
You can assign a tag or expression to the Enter Key
Handshake.
When the operator presses the ENT button to send the value to
the PLC, the terminal sets the Enter Key Control value to 1
(after the Enter Key Control delay, as specified in the Timing
Parameters tab of the Terminal Setup dialog box). To inform the
terminal that the handshake has been received, put a line in
your PLC program to cause a 0 to non-0 transition in the Enter
Key Handshake. When the terminal sees this value change
from 0 to non-0, it changes the Enter Key Control value back
to 0.
Control
(continued) If the terminal does not receive acknowledgment (transition
from 0 to non-0) within the Enter Key Handshake Time (as
specified in the Timing Parameters tab of the Terminal Setup
dialog box), it displays an error message in the Fault Window
and resets the Enter Key Control. If the Enter Key Handshake
is unassigned, the Enter Key Control remains set for the
duration of the Push Button Hold Time or for as long as the
button is pressed, whichever is longer.
Because this control uses only two values, a digital tag is
recommended.
Important: If the Enter Key Control is assigned, all keypad
and touch screen input is disabled when the Enter Key is
pressed, until the Enter Key Control is reset to 0.
You can adjust the size of the scratchpad and format the ASCII Input
object’s foreground color, background color, font style, and border
style. For details on formatting objects see “Changing Object
Appearance” in Chapter 9, Creating Objects, in the
PanelBuilder 1400e Configuration Software for Windows User
Manual.
