Switch Screens
This operation needs 2 consecutive word addresses. When the [Read Address] is switched to
a valid screen No., the current screen will be closed and the specified screen will appear.
Specify the number in the destination screen in the [Read Address]. The number after
switching will be written in [Read Address + 1]
For example, set the address to “LW0”, Data Format to “BCD” and the current screen to Frame
0. If LW0 is changed to 10, the current screen will be switched to Frame 10, and 10 will be
returned to LW1.
Note Each time the [Change Screen] Function Key is pressed, the current screens is closed and the destination
screen is displayed. The function of [Switch Screens] of the PLC control is similar to the [Change Screen]
function of the Function Key. Their difference is the respect whether function is operated by touching the
screen or it is performed by the PLC memory control. When the value of Read Address is modified to an
available screen No., the current screen will be closed and the screen specified with the Read Address
will be displayed. Then the content of the Read Address in written in the Read Address + 1. This
operations can be executed only when the Read Address is modified.
