1. Which components are required? Hardware components: • 1 x bar code scanner (Metrologic IS6520 incl. power supply unit with connector and cable) • 1 x basic unit (07 KT 96, 07 KT 97, 07 KT 98) • 1 x power supply unit 24 V DC (e.g. 07 NG 34) • 1 x adapter between scanner and PLC • 1 x programming cable for the basic unit (07 SK 90) For configuration with terminal (not absolutely necessary) • 1 x terminal (MT45 with ARCNET driver) • 1 x programming cable for the terminal (VB30) • 1 x ARCNET cable incl.

2. Possible configurations 2.1. Minimum variant: PLC and scanner The minimum variant provides a complete configuration for testing the scanner functions. The scanned texts are directly read from the PLC via the programming software 907 AC 1131. The example program is prepared in a way that it is intended for the connection of a terminal via ARCNET. Nevertheless, it is fully functional even without an adaptation.

2.2 Comfort variant: PLC, scanner and terminal The comfort variant also provides a complete configuration for testing the scanner functions. Additionally, the scanned texts can be comfortably viewed on the terminal which is connected to the PLC via ARCNET.

3. Short instruction for commissioning the scanner program FNOTE: The following description exclusively refers to the scanner Metrologic IS6520. The procedure or the corresponding parameters required for other devices may differ. 3.1. Instructions for usage without terminal 1. Connect the scanner to the PLC by connecting the adapter between COM2 of the PLC and the serial connection of the scanner cable. 2.
PAGE 6
3.2. Instructions for usage with a terminal 1. Connect the scanner to the PLC by connecting the adapter between COM2 of the PLC and the serial connection of the scanner cable. 2. Supply the scanner with voltage (connect the cable of the power supply unit to the scanner cable and the power supply unit to 230 V AC; refer to Metrologic manual "Installation and User’s Guide"). 3. Set the scanner parameters: For this purpose, refer to the programming manual of the scanner.

10. Load the project into the MT: Open the project. • Call the project transfer. • The code generator is opened. Press "NO" if you are asked for the bitmaps. • Confirm the ready message with "OK". • Set the transfer interface (e.g. COM 2, 57600 baud – same setting as for the MT) and confirm with "OK". • Question whether the system should also be loaded: The first time this message is displayed it must be confirmed with "YES".

4. The following steps have to be carried out FNOTE: All items marked with an asterisk (*) are only to be carried out if a terminal is connected.
PAGE 9
4.3. Setting the scanner parameters The programming of the scanner is done using bar codes. The bar codes for programming can be found in the programming manual of the scanner. The following codes have to be held in front of the scanning window one after the other. Please note that the scanner requires a certain distance to the bar code to properly recognize the bar code. A beep tone indicates that the scanner has successfully read the bar code.
PAGE 10
4.7. Connecting the ARCNET cable between PLC and terminal This section may only be carried out if you want to use a terminal. Please use a coaxial cable with a characteristic impedance of 93Ω. At both cable ends a terminating resistor of 93Ω has to be installed (refer to documentation 907 AC 1131 part 1, ARCNET descriptions). Connect this cable to the corresponding connectors. 4.8.

• For safety reasons it is now checked whether the interface at the terminal is set correctly.

5. Operating instructions If you have carried out all described steps correctly, your system is now ready for scanning. The scanner reads the bar codes and stores them in a telegram which is sent to the basic unit. The program in the basic unit is designed in a way that it permanently receives the incoming telegrams of the scanner. Then the telegrams are checked whether they are error-free (telegram structure check).
