manual abstract
The DX6400 master Fieldbus communicates with a remote host (for ex. remote PC connected via Internet) by means of a cable connected to the Fieldbus connector provided. It can be activated by a signal generated by the remote Host or by a physical presence sensor. The external signals (trigger, encoder) are connected to the master through the C-BOX 100. The master reader connects to the first slave reader of the system through the local Lonworks 9-pin female connector. Fieldbus models are provided with an internal Lonworks terminator. The slave readers are connected together through the local Lonworks connectors. Only the 9-pin female connector of the last slave reader must be terminated by the BTK-6000 terminator. The example below shows a system powered by the PWR-240 where multiple slaves are connected through CAB-63XX power cable. The master and all slaves are connected together through the CAB-610X cables. The same network layouts are available as for the DX6400 standard model. Sl * P.S. (Presence Sensor) connected to External Trigger/PS input. ** C-BOX 100 modified to accept scanner power. *** The Slave scanners are Master/Slave models, which allow Lonworks network propagation. **** Encoder connected to IN2/ENC input.

This dynamic system, called FLASH™, is able to move the focus position rail to rail, from the minimum position to the maximum position. The FLASH™ functionalities are programmed via the GENIUS™ tool (refer to the GENIUS™ Help On-Line for details) and can operate in the following modes: • Fixed Mode • Continuous Mode • Triggered Mode • D-Flash™ Mode 2.6.1 Fixed Mode In Fixed mode, the focus is set to the desired position via software (expressed in cm). This mode represents the basic Flash™ function, in which the focus is adjusted in software for a given installation and its position is stored in the scanner decoder. This function is similar to the focus adjustment available for the DS6300 scanner with the great difference that the adjustment is performed via software through the Genius™ tool and not through the physical adjustment of an external screw. Figure 48 – Flash™ Fixed Mode 2.6.2 Continuous Mode In Continuous mode, the focus position is continuously moving from a minimum position to a maximum position with a defined frequency (f1 in the figure below). This Flash™ function allows exploiting the whole reading range of the current DX6400 when the object to be detected is large and slow moving. Typical examples of applications for the Continuous mode are front side reading of big pallets, or reading on a fork lift truck. Figure 49 – Flash™ Continuous Mode 2.6.3 Triggered Mode In Triggered mode, the focus position can be set depending on the received external input (photocell, barrier, serial message…). This mode represents the most traditional Flash™ function, since it requires photocells, barriers or a dedicated interface to the Host (PC or PLC). Figure 50 – Flash™ Triggered Mode 2.6.4 D-FLASH™ Mode In D-Flash™ mode, the focus position can be set depending on the measured distance (Dn in the figure below) between the scanner and the scanned object. This is the most innovative and flexible function, that makes different software implementations possible. The D-FLASH™ development has been based on the minimum distance detected. Thus, it can apply to the widest variety of applications. Further developments of D-FLASH™ will be provided according to the specific application needs. Figure 51 – Flash™ D-Flash™ Mode 2.7 KEYPAD AND DISPLAY The DX6400 keypad allows entering a menu for selection of one of the following functions: • Welcome: shows the current software release and operating mode; • Autolearn: starts the procedure making it possible to obtain an automatic, accurate and fast configuration of DX6400 without the necessity of directly checking/modifying the relevant parameters; • Internal Net: defines scanner function within the network (see below); • Ethernet Mode: allows setting the scanner IP address to be used within the network; • LCD Contrast: sets the LCD contrast; • Bus: allows setting the scanner address (value range 0-125) to be used in a Profibus network; • Test Mode: allows verifying the scanner reading position an...
