7.3.2 Procedure - Confirming the Communication State

Create a lamp to acknowledge when a communication scan is running.

1. From the [Parts (P)] menu, point to [Switch Lamp (C)] and select [Lamp (L)] or click to place a lamp on the screen.

2. Double-click the placed lamp. The Switch/Lamp dialog box appears.
   

3. Use [Select Shape] to define the frame of the lamp.

4. Set the bit address to acknowledge the exclusive state of the communication scan in [Bit Address].

   

   • Use the internal device address LS9560 - LS9567 to acknowledge the execution or stop of the communication scan.
     
     For example, you can acknowledge up to 16 communication scans of driver 1 using LS9560.
     [LS9560]
     
     Bit 0: OFF when the first I/O Driver1 is scanning. ON when the scan is stopped.

   • If you designate a 32-bit device in [System Area Start Address], you can set 32 bits in the LS area. However, you can only use the lower 16 bits to acknowledge the execution of the communication scan.

5. Click the [Color] tab and set the Lamp display colors. Set a [Display Color], [Pattern] and [Border Color] for each case where the [Select State] is ON or OFF.

   

   • Depending on the shape, you may not be able to change the color and pattern.

6. Click the [Label] tab. Define the label to appear on the Lamp. Specify the font type and size, and then in the rectangular field type the text to display. Click [OK].

   

   • When you select a switch and press the [F2] key, you can directly edit the text on the label.
