Entering and editing numerical values
Introduction
You enter numerical values depending on a type of HMI device, either with the system keys
or the screen keyboard. You can also connect an external keyboard.
Note
When the screen keyboard is open, job mailbox 51, "Select screen" has no function.
●
With key HMI devices, only the numbers on the system keys are available.
●
With touch HMI devices, a numerical screen keyboard opens.
Date and time
Date and time are entered in the same way as numerical values.
Note
When entering the date and time, note that their format is determined by the configured
project language.
Entering hexadecimal values
If the configuration engineer has configured the I/O field as "Hexadecimal display", the letters
"A" to "F" are available in addition to the numbers.
With touch devices, the alphanumeric screen keyboard appears in this case. The keys "G" to
"Z" are not used. When you press the keys, a beep is emitted.
Limit test of numerical values
Tags can be assigned limits. If you enter a value outside these limits it will not be accepted,
for example, "80" is rejected if the configured limit is "78". When an alarm window is
configured, a system alarm is generated on the HMI device. Regardless of this, the original
value is displayed again.
Decimal places for numerical values
The configuration engineer can specify the number of decimal places for a numerical text
box. The number of decimal places is checked when you enter a value in this type of I/O
field.
●
Decimal places in excess of the limit are ignored.
●
Empty decimal places are filled with "0".
