Inputting Numeric Values

For a numeric key type numeral setting input field, the check is executed when
an attempt is made to confirm a numeric value. If the value is higher than the
upper limit or lower than the lower limit, the buzzer sounds three times and the
input value is cleared (the status returns to that before input was attempted).
Note When the numeral values entered are confirmed, upper/lower limits are
checked.
serve the following upper/lower limit settings at the Support Tool when numbers
are being input in hexadecimal with its unlimited input range.
• The following values are recognized internally in the PT.
1 word: 8000
H
2 words: 8000 0000
(–2,147,483,648 ↔ 0 ↔ 2,147,483,647 decimal)
• In the Support Tool, the upper/lower limits are set in decimal. (The $ prefix can
be added to input hexadecimal values.
Using the figures above, the following table shows the upper/lower limits to be
set at the Support Tool.

Interlock Function
A numeral input can be controlled (enabled/disabled) from the PC by setting the
interlock function for the numeral input and allocating an interlock bit in a PC data
area. The status of the allocated interlock bit is read and its status determines
whether the input is enabled or disabled.
The following table shows how the PT operates when the interlock function is
used or not used.
Interlock
function
Used Numerical values can be input only while the interlock bit is ON.
If you attempt to input a value while the interlock bit is OFF, the buzzer
will sound and the input field will not change. When an input is made
from a temporary input field to the interlocked numeral input while the
interlock bit is OFF, the buzzer will sound when the value in the
temporary input field is confirmed and the destination numeral input
field will not change.
Not used Values can be input and confirmed at any time.
The PT continuously reads the status of the corresponding interlock bit while a
numeral input field that uses the interlock function is being displayed on the
screen. if the interlock bit's status changes, the numeral input field is disabled or
enabled according to the interlock bit's status.
switch setting, the buzzer won't sound when you attempt to input a value in an
interlocked input field.
Interlock Bit Allocation
Interlock bits can be allocated to the following host (PC) areas.
