*1 LR 00000 to LR 00199 are converted to CIO 01000 to CIO 01199.
*2 The EM Area is supported only by the C200HX/HG/HE(-Z)E PLCs.
The Auxiliary Area of the CVM1 and CV-series PLCs is allocated to system
functions, and cannot be used for purposes other than system use.
The range of each memory area differs according to the PLC. Refer to Appen-
dix D Making the Cable on page 153.
1. Use the support tool to allocate the PT status control area (PLC to PT) to
the PLC memory.
2. Create a PLC program to write the number of the displayed screen to the
"screen switch setting word" in the PT status control area.
Use a 4-digit BCD (binary-coded decimal) value to set a screen number.
If a screen has been switched by operating the PT status control area (PLC to
PT), the contents of the "currently displayed screen word" in the PT status
notify area (PT to PLC) also change.
• Screen switching timing
The NT11 screen switches when the contents of the "screen switch setting"
have changed. To re-specify the number of the currently specified screen,
first write the value 0000 to clear the screen before writing the appropriate
screen number.
