After READ (F1) or WRITE (F2) has been pressed, the display will show the first variable
in the list. An example is shown in Figure 12. Each time NEXT (F2) is pressed; the display
will show the next variable in the list. PREV (F1) will show the previous variable. You can
also use the Up and Down Arrow Keys to move through a list.
Automatic wraparound occurs in either direction. When you reach the end of the list, [F1]
will display the first variable again. At the top of the list, [F2] will display the last variable.
E4.1.6 Changing Variable Parameters
From Figure 11, you can change variable parameters by pressing F2 [Write]. Then follow
the directions summarized below (see Note 2).
Note 2: If your display does not contain the legend Write in the legend line, your password
will only allow you to read variables. If you want to change variable values at this
time, you must first log-off and then log-on using the correct password. See your
Systems Engineer for the correct password.
