Description
Determining the Screen Displayed on the PT
1, 2, 3...
The lamp and touch switch displays are processed more rapidly if the PT Status
Control Area is allocated to the general memory. Refer to 3-3 PT Status Control
and Notification for more details. These bits are used in the same way as the
allocated control bits.
Notify bits can be allocated to lamps and touch switches in addition to the control
bits. The notify bits inform the PC whether a touch switch has been pressed. Re-
fer to 4-11 Determining Touch Switch Status.
A touch switch is “lit” by highlighting the displayed touch switch.
This example controls the bits to move a robot arm and turning the lamps on and
off.
Allocate the memory as follows using the Support Tool:
Lamp #0: 00200 (output bit to raise robot arm)
Lamp #1: 002001 (output bit to lower robot arm)
Lamp #2: 00202 (output bit to rotate robot arm counterclockwise)
Lamp #3: 00203 (output bit to rotate robot arm clockwise)
Lamp #4: 00204 (output bit to clamp rotate robot arm)
Lamp #5: 00205 (output bit to unclamp rotate robot arm)
Create a screen as shown below to display Lamps #0 to #5 with the Support Tool
and transfer it to the PT. Set the display attribute to “Light”.
No PC ladder program is required to control the PT. Only a program to control the
robot arm movement is required.
When the ladder program is executed to control the robot arm, the PT lamps turn
on and off in synchronization with the arm movement.
For example, Lamp#0 lights when the robot arm ascends and goes out when it
stops ascending.
The screen displayed on the PT can be determined by reading the Currently Dis-
played Screen from the the PT Status Notify Area allocated in the PC memory.
When the screen is switched, the PT Status Notify Area is notified as follows:
1. Use the Support Tool to allocate the lamp and touch switch Control Bits to
2. Create a PC program to set the Control Bits on or off to light (flash) or extin-
the PC memory. Use the display attributes to set if each lamp and touch
switch flashes or lights continuously.
