Connection of a serial bar code scanner
In this example a bar code reader is connected to the EL6001. Characters will be read by the reader until the
ASCII character 0x0D (13
dec
, CR) is received.
Data:
• Quick task for executing the serial communication: 1 ms cycle time
• Standard PLC task: 10 ms cycle time
• Barcode scanner on channel 1
• TwinCAT 2.11 required
• “TwinCAT PLC Serial Communication” supplement is required
A detailed description for the use of the serial communication library is stored in the Beckhoff Information
System.

Starting the example program
The application examples have been tested with a test configuration and are described accordingly.
Certain deviations when setting up actual applications are possible.
The following hardware and software were used for the test configuration:
• TwinCAT master PC with Windows XP Professional SP 3, TwinCAT version 2.11 (Build 1528) and
INTEL PRO/100 VE Ethernet adapter
• Beckhoff EK1100 EtherCAT coupler, EL6001 terminals
• Serial barcode scanner with 9-pole sub-D connector
Procedure for starting the program
• After clicking the Download button, save the zip file locally on your hard disk, and unzip the *.TSM
(configuration) and the *.PRO (PLC program) files into a temporary working folder
• Run the *.TSM file and the *.PRO file; the TwinCAT System Manager and TwinCAT PLC will open
• Connect the hardware in accordance with fig. 1 and connect the Ethernet adapter of your PC to the
EtherCAT coupler (further information on this can be found in the corresponding coupler manuals)
• Select the local Ethernet adapter (with real-time driver, if one) under System configuration, I/O
configuration, I/O devices, Device (EtherCAT); on the “Adapter” tab choose “Search...”, select the
appropriate adapter and confirm (see Fig. 2a + 2b)
