The range of each memory area differs according to the PC type. Refer to
Appendix B PC Memory Map for more details.
All unallocated bits are 0 (OFF) in the word to which the touch switch notify bits
are allocated. Do not use this word for any other purpose other than allocation of
touch switches.
Be sure to allocate each touch switch on a single screen to different bits.
touch switch notification than allocating the bits to other areas of the memory.
Refer to 3-3 PT Status Control and Notification for details. These bits are used in
the same way as notify bits allocated to other parts of memory.
The screen attributes are ignored when Direct Connection is used. The attrib-
utes are permanently set as a Touch Switch.
In addition to the notification function, the following two other functions can be
allocated to touch switches with the Support Tool. When one of these functions is
specified, the allocated bits are not notified of the touch switch status.
Refer to the appropriate PT Operation Manuals for details about these functions.
This example uses the touch switches as normal switches for use as a PT oper-
ating panel.
Allocate the touch switches as follows using the Support Tool:
Set the touch switch function to Notify Bit.
Create a screen which displays touch switches numbers 10 and 11 as shown
below and transfer it to the PT. Set the display attribute to “Light”.
Allocating the bits to the PT Status Notify Area general memory achieves faster
1. Use the Support Tool to allocate the touch switch notify bits to the PC
2. Write a PC program to read and check the allocated notify bits.
