Since all the CVM1/CV-series AR area bits are allocated to the system, they
cannot be used for applications not related to the system.
The range of each memory area differs according to the PLC type.
Note (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.
When making a data memory (DM) specification, specify the bit number (00 to
15) following the word number.
5-3-4 Lit (Flashing) and Unlit Touch Switch Status
(Changing the Status of Allocated Bits)
This section describes how to change the status of allocated bits and thereby
the status of the touch switches displayed by the NT20.
The status of touch switches displayed by the NT20 is changed by switching
the control bits allocated in the PLC memory ON and OFF.
The status of the lamp bit reflects the touch switch status, as follows:
0 (OFF): Unlit
1 (ON): Lit (inverse display) or flashing
1,2,3... 1. Use the Support Tool to allocate the touch switch lamp bits to the PLC
memory.
2. When creating the screen data using the Support Tool, register the touch
switch for a screen.
3. Create the PLC program to switch the lamp bit of the touch switch ON and
OFF.
Set whether the lamp lights continuously or flashes when the bit comes ON
by setting the touch switch display attribute with the Support Tool.
