6 Balluff Network Interface / I/O Profibus Modules 2 Safety 2.1 Intended use The BNI PBS-... serves as a decentral in- and output module for connecting to a Profibus-DP network. It may be used only for this purpose in an industrial environment corresponding to Class A of the EMC Law. 2.2 General safety notes Installation and startup Installation and startup are to be performed only by trained specialists. Any damage resulting from unauthorized manipulation or improper use voids the manufacturer's guarantee and warranty. The device corresponds to EMC Class A and is designed only for industrial use. RF interference may result from operating the device in the open low-voltage network. In this case the operator must take precautionary measures accordingly. The device may be operated only using an approved power supply (see Section 5 "Technical Data ). Material resistance The BNI PBS-... has good chemical and oil resistance. If aggressive media are used, the material resistance must be tested for this application. Operation and testing The operator is solely responsible for ensuring that the prevailing safety and accident prevention statutes are followed in the respective application. In case of defects or faults which cannot be immediately remedied, the device must be taken out of service and secured against unauthorized use. Proper operation of the device is ensured only when the housing is fully installed 2.3 Meaning of the warnings Note! The pictogram used with the word "Caution" warns of a possible hazardous situation affecting the health of persons or equipment damage. Ignoring these warnings can result in injury or equipment damage. Always observe the described measures for preventing this danger. 6

10 Balluff Network Interface / I/O Profibus Modules 6 Installation 6.1 Mechanical connection Fig. 6-1: Dimensions in mm The BNI PBS-... module can be connected directly to a mounting wall or to a machine. Be sure that the mounting base is flat to prevent any mechanical stress on the device housing. Two M6 screws and two washers are required for mounting. The tightening torque is 9 Nm. Installation: Attach module using two M6 screws and 2 washers. Keep a distance of at least 3 mm between two modules. 10

11 Balluff Network Interface / I/O Profibus Modules 6 Installation 6.2 Electrical connection Function ground The ground connection for the BNI PBS-... modules is located at upper left next to the mounting hole. Ground straps are preferred for the ground connection. Alternately a fine-strand PE wire with large cross-section may be used. Fig. 6-2: Ground connection Note! The FE connection from the housing to the machine must be low-impedance and as short as possible. Supply voltage Profibus modules require a DC voltage of 24 V DC (SELF/PELF) for power. The power can be provided by regulated and unregulated power supplies. Regulated power supplies allow the output voltage to be increased above the nominal voltage to compensate for line losses.

Use different power sources for the sensor/bus and for the actuator if possible to minimize noise susceptibility. Total current < 9 A. The total current of all modules may not exceed 9 A even when daisy chaining the actuator supply. Note! The conductor cross-section is limited by the 7/8" connector to max. 1.5 mm². 11

12 Balluff Network Interface / I/O Profibus Modules 6 Installation 6.3 Bus connection The bus connection is made using the M12 sockets Profibus IN and Profibus OUT.

14 Balluff Network Interface / I/O Profibus Modules 7 Startup 7.1 Profibus address Addressing Assigning and setting the Profibus address Die Profibus address is set directly on the BNI PBS-... using two BCD switches. Permissible address range Each Profibus node must have a unique and one-time address assigned to it. The address is read once after power is turned on. If the address is changed, this change becomes effective after a power reset on the module. Fig. 7-1: Addressing switch A DP Master is generally assigned addresses 0 to 2. For the PBS modules we recommend using addresses 3 and higher. 7.2 Configuration GSD file When project planning Profibus devices, a device is mapped as a modular system which consists of a header module and multiple data modules. The device data required for project planning are stored in GSD files (GenericStation Description). The GSD files are available in two languages for downloading over the Internet ( Header module Structure of the header modules First the header module is inserted into the configuration. The header module is coded according to the special identification format. Header modules in this coding are used for identification and parameter setting and have a data width of 2 bytes input of 2 bytes input/output data.

In this case both LEDs are red. Diagnostics input Pin 2 of the I/O port can be configured as a diagnostics channel It behaves like an inverted input. The 0 V signal is interpreted as 1, the corresponding Port LED comes n red and a diagnostics message is sent over DP-Diagnostics. The optical indicator on the corresponding I/O port allows defective sensors/actuators to be more easily and quickly localized. 30

31 Balluff Network Interface / I/O Profibus Modules 8 Diagnostics 8.2 Diagnostics telegram Norm diagnostics The diagnostics telegram is comprised of various blocks. The first 6 bytes are defined by the Profibus standard EN The following 4 bytes are device-specific and ID-specific diagnostics information (2 bytes each). For each channel-specific diagnostic 3 bytes of diagnostics information are added (min. 6 and max. 244 bytes). Byte Bit 0 Status 1 1 Status 2 2 Status 3 3 Master address 4 Ident_Number_High_Byte For BNI PBS-Modules: 0Bhex 5 Ident_Number_Low_Byte BNI PBS : 1Dhex BNI PBS : 1Chex Note! When coding the norm-specific diagnostics: 1 = activated, 0 = deactivated Norm diagnostics coding Status 1 In the following the coding of bytes 0 to 3 of the norm diagnostics is described. Byte 4 and Byte 5 (Identnumber) are fixed. Byte 0, Status 1: Bit Meaning 0 Station_non_existent The DP-Slave always sets the bit to 0. The DP-Master sets it to 1 if the DP-Slave cannot be reached. 1 Station_not_ready The DP Slave sets the bit to 1 if it is not yet ready for data exchange. 2 Cfg_Fault The DP Slave sets the bit to 1 if the configuration data last received from the Master do not agree with those which the DP Slave determined. 3 Ext_diag If the bit is set to 1, there is a diagnostics entry in the slave-specific diagnostics area (Ext_Diag_Data). An expanded diagnostic follows in the telegram. 4 Not supported The DP Slave sets the bit to 1 if a function was requested which is not supported. 5 Invalid_Slave-Response The DP-Slave always sets the bit to 0. The DP-Master sets it to 1 if it receives an implausible response from the DP Slave. 6 Prm_fault The Slave sets the bit to 1 if the last parameter telegram was defective (e.g. wrong length, wrong ID number, invalid parameters). 7 Master_lock The DP Slave always sets the bit to 0. The DP Master sets it to 1 if the DP Slave was parameterized by a different Master (Lock from another Master, here: Address in byte 3 not equal to FFhex and not equal to its own address). 31

32 Balluff Network Interface / I/O Profibus Modules 8 Diagnostics Status 2 Byte 1, Status 2: Bit Meaning 0 Prm_req The DP Slave always sets the bit to 1 if it needs to be reconfigured and parameterized. The bit remains set until parameterizing is done. 1 Stat_Diag (static diagnostic) The Slave sets the bit to 1 if for example it can not send valid data. In this case the DP Master retrieves diagnostic data until the bit is reset to 0. 2 Fixed at 1 3 WD_On Monitoring activated/deactivated (Watchdog on). 4 Freeze_Mode The Slave sets the bit to 1 if it has received the Freeze command. 5 Sync_Mode The Slave sets the bit to 1 if it has received the Sync command. 6 Not_Present The DP Slave always sets the bit to 0. The DP Master sets it to 1 for the DP Slaves which are not contained in the Master parameter set. 7 Deactivated The DP-Slave always sets the bit to 0. The DP-Master sets it to 1 if the DP-Slave is removed from the Master parameter set. Status 3 Address Byte 2, Status 3: Bit Meaning reserved 7 Ext_Diag_Overflow If this bit is set, there is more diagnostics information than indicated in Ext_Diag_ Data. For example the DP Slave sets the bit to 1 if there is more channel-specific diagnostics information than the DP Slave can enter in its send buffer. A DP Master sets the bit to 1 if the DP Slave sends more diagnostics information than the Master can hold in its diagnostics buffer. Byte 3, address of the Master: Bit Meaning Master_Add After parameterizing the address of the DP Master which has parameterized the DP Slave is entered. If the DP Slave has not be parameterized by a Master, it sets address FFhex.
