Slave devices
Slave devices do not support the display of Numeric Entry variables
in messages. Numeric Entry variables are removed from a message
by the master MessageView terminal before the message is slaved.
Although slave devices do not display Numeric Entry variables in a
message, the master terminal does display them whenever it displays
the message.
ASCII Triggering devices
Tag Node Name and Address attributes are ignored by an ASCII
Triggering device. They may be omitted when creating applications
for use with such a device.
An ASCII Variable Entry allows the terminal operator to change to
change or enter a value stored at a controller address. This variable
may be used in an application designed for a terminal that has both a
daughterboard (Catalog No. 2706-M1D1, -M1N1 or -M1F1) and
firmware that can support an ASCII Input device.
An ASCII Variable Entry allows the entry of:
•
numeric values from the front keypad
•
alphanumeric characters from an ASCII Input device; input
devices are listed on Page 5–6.
If the ASCII Entry variable is defined as:
•
an integer (signed or unsigned) the entered data is displayed in
numeric format. It may be scaled like data in a Numeric Entry
variable.
•
a character array, the entered data is displayed in alphanumeric
format. It cannot be scaled.
To create the variable, set the insertion pointer in the Message Edit
box where the variable should be placed.
•
Click the Embedded Variable tool on the Message Edit toolbar
and select Numeric Variable Entry on the dialog.
•
Or select the ASCII Variable Entry command on the Format
menu.
To edit the variable, highlight the variable placeholder in the
message.
•
Click the Embedded Variable tool.
•
Or select the Edit Variable command on the Format menu.
