Lamps, Touch Switches, Numeral Setting
Section 6-4
Cautions when bit input is permitted
If the touch switches are set in the following positions using the support tool while
the setting is “bit input permitted”, the following operations will occur due to the
configuration of the touch switches.
Take this into consideration when setting touch switch areas.
Example 1:
Touch switches are set at positions A, B, C, and D using the minimum switch set-
ting unit.
S
If switches A, B, and C are turned ON at the
same time, switch D is also set ON.
S
Similarly, if switches A, B, and D are turned ON
at the same time, switch C is also set ON.
A
C
D
B
Example 2:
Touch switch areas E, F, and G are set.
S
If switches E and F are turned ON at the same
time, switch G is also set ON.
E
F
G
Touch switch notification/control and attributes
Inverse and normal display states can be set as attributes of touch switches by
using the support tool. There are slight differences in the operation when a touch
switch is pressed depending on whether bit input is permitted or not permitted.
Bit input not permitted: Touch switch notification by number
The touch switch is lit for 0.2 seconds when pressed and then returns to the
unlit status.
Bit input permitted: Touch switch notification by bit information
The touch switch is lit while pressed and returns to the unlit status when re-
leased.
When a touch switch which is currently lit or flashing is pressed, it is continuously lit
while pressed and returns to its original state when released.
Simultaneous pressing of multiple touch switches
Two or more touch switches can be simultaneously pressed if their statuses are
notified by bit information or if they use different host notification methods. Howev-
er, two or more switches cannot be simultaneously pressed if their statuses are
notified to the host by their numbers.
