Standard Mode
The value of the variables is loaded from the controller when the mask
is accessed.
If you select the attribute Cyclical, the system constantly updates the
value of the variables, based on the interval specified in the polling
time.
Before input, the operator must press the Data Release key. The oper-
ator can only change the value of the variables once the status LED for
the data release is lit. Use the Enter key to write the value to the con-
troller. The operator must then press the Data Release key. The status
LED for the data release switches off.
5.5.4.2 Output
Select the field type Output to only display the value of the variables,
but not allow the operator to change the value.
The value of the variables is loaded from the controller when the mask
is accessed.
If you select the attribute Cyclical, the system constantly updates the
value of the variables, based on the interval specified in the polling
time.
5.5.4.3 Password
You can use the additional attribute Password to determine for an
alphanumeric variable that the password is not visible on the operating
device when it is entered.
Instead of displaying the values entered, the system displays the oper-
ator a string of “X“ when the password is entered.
5.5.4.4 Cyclical
The operating device always polls the controller for the value of a vari-
able when the operator goes to a mask in which a value is to be dis-
played. However, to display actual values, the value must be
continuously updated. Therefore, always select the field type Cyclical
for displaying actual values.
The system will then continuously update the value of the variables,
based on the interval set as the polling time.
