6-3-3 Allocated Bits, and Display, of Touch Switches

Method for PC Notification and NT600S Control

Two types of bit can be allocated to touch switches: notify bits - which serve to notify statuses to the PC - and control bits, lamp bit, which control the lighting (flashing) of the touch switches. (For other types of function, only lamp bits can be allocated.) When a touch switch is pressed the notify bit status changes and, when the lamp bit is ON, the touch switch lights (or flashes).

In order to notify the status of a touch switch to the PC, the touch switch must be allocated to a specified PC bit so that it can be managed. Designate the area and bit number.

To use touch switches for notification to the PC, the following settings must be ￿made using the support tool: “touch switch” -- “bit setting” -- “notify bit”.

Types of notification operation

When using Ver.5 of the direct connection function, the notification operation when the touch switch is pressed can be selected from the following four types (with Ver.4 direct connection, the type is fixed as “momentary”):

-Momentary

When the touch switch is pressed the bit comes ON; when it is released the bit goes OFF.

-Alternate

Each time the touch switch is pressed, the bit status changes from ON to OFF or OFF to ON.

-Set

When the touch switch is pressed, the bit comes ON and remains ON even if the switch is pressed again.

-Reset

When the touch switch is pressed, the bit goes OFF and remains OFF even if the switch is pressed again.
