8.7.1 Editing Parts
When the communication scan of device addresses on the screen is stopped, the special relay LS2032 (bit 1) and LS2033 (bit 1) do not automatically turn OFF.
You cannot stop the communication scan of a device specified with the System Area Start Address. However, if you are not using the System Data Area, you can stop the communication scan.
5.4.6 System Settings [Display Unit] - [System Area] Settings Guide
When communication is interrupted (communication scan is stopped), an error occurs when a switch, script, logic program, Pro-Server EX, or other function attempts a write operation to the corresponding device/PLC. To remove the error, restart communication with the corresponding device.

To control communication with the device/PLC using touch operations, create a switch for each bit in the communication scan control address that corresponds to a device/PLC. When bit is ON, stop scan. When bit is OFF, start scan.

On the [Parts (P)] menu, point to [Switch Lamp], and select [Bit Switch (B)], or click to place a switch on the screen.

Double-click the placed Switch part. The following dialog box appears.

In [Select Shape], select the Switch shape.

In [Bit Address], set the address to start and stop communication scans.

Use internal device addresses LS9550 - LS9557 to control the start or stop of the communication scan.

For example:
By using LS9550, you can control communication scans for 1 to 16 units in Driver 1.
LS9550

Bit 0: Turns scan ON or OFF for Driver 1, PLC 1.
Turn ON Bit 0 to stop communication scans for Driver 1, PLC 1. Turn OFF Bit 0 to resume the scan.
If you designate a 32-bit device in [System Area Start Address], you can set 32 bits in the LS area. However, you can use only the lower 16 bits to control the communication scan.
When you stop the communication scan, the displayed device/PLC data will remain. However, if you change screens and then display the screen again, the device/PLC data will not be displayed.

From [Bit Action], choose [Bit Invert].

As needed, set the color and display text on the [Color] tab and [Label] tab, and click [OK].

Depending on the shape, you may not be able to change the color.
When you select a switch and press the [F2] key, you can directly edit the text on the label.
