16.2.3 Procedure - Connecting a Two-dimensional Code Reader

Configure settings to store the code data read from a two-dimensional code reader from LS20 in the display unit.

1. From the System Settings, click [Input Equipment] to display the following screen.
   

2. From the [Type] drop-down list, select [Two-Dimensional Code Reader].
   

3. In the [Port] drop-down list, select the port to which you want to connect.

   

   • If the port is also used for other devices/PLCs, displays to the right of the [Port] as above.

   • A two-dimensional code reader can be set in COM1, USB, and USB/SIO. When IPC Series is selected on the Display, only COM1 can be set.

4. Set the [Read Mode].

5. In [Communication Settings], set [Speed], [Data Length], [Parity], [Stop Bit], [Flow Control], and [5V Power Supply].

6. From the [Save Data In] drop-down list, select a data storage location.

7. From the [Internal Device Storage Start Address], set the data storage internal device's start address.
   

   

   • For the internal device's address setting range, refer to 16.2.1 Code Data storage area.

8. Click [Extended] to configure the [Read Completion Bit], [Data Size] and [Initialization Settings].
   

   

   • When [Read Completion Bit] is not set, when data is read continuously the data gets overwritten.

   • If [Read Completion Bit] is set, turn OFF the [Read Completion Bit] when input is complete. The display unit will not read code data without turning the read completion bit OFF.
