Create snapshot of monitor values
You can back up the current values of the technology object on the CPU (monitor values)
and display them in the Parameter view.
● There is an online connection.
● The technology object is downloaded to the CPU.
● The program execution is active (CPU in "RUN").
● The Parameter view of the technology object is open.
● The “Monitor all” button
is selected.
To show the current parameter values, follow these steps:
1. In the Parameter view, click the “Create snapshot of monitor values" icon
.
The current monitor values are transferred once to the "Snapshot" column of the parameter
table.
You can analyze the values "frozen" in this way while the monitor values continue to be
updated in the "Monitor values" column.
With the Parameter view, you can modify values of the technology object in the CPU.
You can assign values to the parameter once (Modify value) and modify them immediately.
The modify request is executed as quickly as possible without reference to any particular
point in the user program.
Danger when modifying:
Changing the parameter values while the plant is operating may result in severe damage to
property and personal injury in the event of malfunctions or program errors.
Make sure that dangerous states cannot occur before you use the "Modify" function.
