PC ladder program
No PC ladder program is required to control the NT620S/620C. Only a pro-
gram to control the robot arm movements is required.
S
Program operation
When the ladder program to control the robot arm is executed, the lamps on the
NT620S/620C screen turn ON and OFF in synchronization with the robot arm
movement.
For example, lamp No. 0 lights when the robot arm moves up and goes out
when it stops moving up.
5-3-3 Allocated Bits, and Display, of Touch Switches
Method for PC Notification and NT620S/620C Control
Two types of bit can be allocated to touch switches: notify bits, which serve to
notify statuses to the PC, and control bits, which control the lighting (flashing) of
the touch switches (for other functions, only lamp bits can be allocated). When a
touch switch is pressed the notify bit status changes and, when the control 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”.
S
Types of notification operation
When using Ver.2 or a later version of the direct connection function, it is pos-
sible to select one of four types of notification operation that occur when the
touch switch is pressed (with Ver.1 of the direct connection function, the setting
is fixed as “momentary”).
