Connection box C-BOX 300 Safety precautions 1 Safety precautions 1.1 Power supply Read this information before installing the product • This product is intended to be installed by Qualified Personnel only. The C-BOX 300 is intended to be supplied either by a UL Listed NEC Class 2 power source, or a UL Listed ITE Limited Power Source (LPS), rated 10 ... 30 VDC, minimum 0.5 A. 1.2 Safety notes Observe the general rules for PROFIBUS components when planning the C-BOX installation.
Connection box C-BOX 300 Safety precautions Bus connectors It is recommended to use only commercially available PROFIBUS connectors for connecting the bus. Cable shield Shielded cables are less sensitive to interference due to electromagnetic fields. With shielded cables, the interference currents are led to ground through the shielding rail, which is electrically connected to the case.

Connection box C-BOX 300 Installation 4.7 Profibus Node Address Selection To interface the C-BOX 300 with a Profibus network, the Node Address should be set using the rotary switches placed in the cover inside. The valid address range is from 000 to 126. If an invalid value is detected (127-199) the C-BOX cannot communicate with the Profibus network and the green LED remains off. The Node Address can also be assigned through VisoSetup. Refer to Help on-Line. HUNDREDS Figure 4.8 4.
Connection box C-BOX 300 Installation 4.9 C-BOX 300 Configuration for Profibus DP Slave Node In order to setup the C-BOX 300, you need to install the function blocks in your PLC programming software and configure it. The procedure below can be generally applied for this purpose: 1. 2. 3. 4. Start the PROFIBUS configurator on the DP Master.

Connection box C-BOX 300 The C-BOX PROFIBUS protocol implementation 5 The C-BOX PROFIBUS protocol implementation 5.1 Definitions In the following description we will use the following definitions: • Input field: is the set of master inputs that can be modified by the specific slave • Output field: is the set of master outputs that can be read by the specific slave. • MaxInBytes: is the number of input bytes shared by the master and the specific slave.
Connection box C-BOX 300 The C-BOX PROFIBUS protocol implementation 5.3 Dynamic PROFIBUS Driver (DPD) The Dynamic PROFIBUS Driver (DPD) is a layer that is built upon the intrinsic DP data exchange mechanism. Such a layer is required because the intrinsic DP PROFIBUS mechanism is not message oriented (a service that otherwise might be easily obtained if the PROFIBUS FDL layer were available). PROFIBUS DP could be better seen as a method to share memory between remote stations.
Connection box C-BOX 300 The C-BOX PROFIBUS protocol implementation • byte 2: Service Access Point Field, used to distinguish among different services but also to provide future expandability. Since this SAP definition is introduced by the Datalogic PROFIBUS Driver, it must not be confused with the PROFIBUS SAP that is defined by the international standard. • byte 3: Length Field, that contains the number of bytes used by the application layer.
Connection box C-BOX 300 The C-BOX PROFIBUS protocol implementation More precisely: Function of the IN[0] byte: IN[0].bit0 = TxBufferFull, toggles when new data is available on IN[1] .. IN[Nin] input area IN[0].bit1 = RxBufferEmpty, toggles when rx block has been read on OUT[1] .. OUT[ Nout] IN[0].bit2 = Resync Acknowledge, set to 1 as an acknowledge to a resync request. With this bit, the master can detect a slave is on line. IN[0].

Connection box C-BOX 300 The C-BOX PROFIBUS protocol implementation 5.5.2 Data transmission master --> slave The receive state machine is shown to understand how a single block is transmitted by the master and received by a slave. This protocol guarantees a basic flow control mechanism from master to slave. First bit shown in transition --> OUT[0].1 / RX Buffer Full = data written by master Second bit shown in transition --> IN[0].
Connection box C-BOX 300 The C-BOX PROFIBUS protocol implementation 5.5.4 Fragmentation and reassembling When application data cannot be contained into the related Exchange Area buffer, a fragmentation process should be activated. This is always done at the C-BOX side. C-BOX is not able to manage application buffers longer than 256 bytes (this is true both when it fragments and when it reassembles). The fragmentation process is initiated by setting the More Bit (bit 3) of the related buffer to 1.
Connection box C-BOX 300 The C-BOX PROFIBUS protocol implementation 5.6 C-BOX PROFIBUS station address field The INPUT and OUTPUT buffers keep the information of the selected PROFIBUS address in this field. 5.7 SAP field SAP (Service Access Point) is an identifier that is used to share the same communication channel between processes of two remote stations. This allows splitting the single PROFIBUS DP service into different services.
Connection box C-BOX 300 The C-BOX PROFIBUS protocol implementation SAP=2) will permit application events to be queued in the opposite direction, waiting for use by the C-BOX application layer. The queues are sized in the following way: • X elements of 32 bytes each for input queue (flow from C-BOX to the Master station); • Y elements of 32 bytes each for output queue (flow from the Master station to CBOX). The number of 32-byte elements X and Y are application dependent.
Connection box C-BOX 300 C-BOX data collection using minimum flow control Application data areas are to be formatted as follows: Request Format Command Flush data buffer byte 4 '[' byte 5 'F' Response Format depending on the Retcode Retcode byte 4 byte 5 Command accepted 'A' '' Command rejected 'C' '' All other bytes are insignificantly. 6 C-BOX data collection using minimum flow control Some examples of the Datalogic PROFIBUS Driver (DPD) managing C-BOX are described for the following cases.
Connection box C-BOX 300 C-BOX data collection using minimum flow control 6.2 What to Implement As a result of the previous definitions we have that: 1. 2. 3. 4. 5. 6. 7. 6.3 C-BOX toggles the first bit of the first byte of the input area whenever a new barcode event is inserted in the input area; this will happen if and only if the previous barcode event had been acknowledged by the Master.
