7.3.1 Procedure - Stop Communications

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.

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

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

  3. In [Select Shape], select the Switch shape.

  4. 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.

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

  6. 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.
