Product description 1 Product description VEGACOM 557 is an interface converter for conversion of VEGA specific protocols of DISBUS and LOGBUS into standard data formats. The existing version of VEGACOM 557 is used to convert data into the PROFIBUS FMS data format (FMS = Fieldbus Message Specification). As a peripheral device (Slave), the instrument can be connected to a PROFIBUS data line. The bus access is realised according to the Master-Slave procedure, enabling the master (e.g.
Product description The data set is transferred from this buffer memory into a process image. The protocol conversion software enquires the stored data cyclically from the individual storage areas. The data sets are checked and converted into the PROFIBUS data format. After the conversion, the data are transferred into emission memory and are sent from there to the PROFIBUS. The PROFIBUS transmits the data to the PROFIBUS master, loading them via a special connection component.

Setup 4 Setup In this section, all measures you need to take to set up your VEGACOM 557 in conjunction with the Siemens communication processor CP5431 are described. If your PROFIBUS master is an instrument from another manufacturer, please observe the necessary measures found in the respective manufacturer documentation. In the setup procedure, the parameters of the communication processor must be set first.
Setup 6 Integrate S5 program (on diskette), which reads in measured values, into your own application - Enquire in OB21 and OB22 the functional component FB249 (SYNCHRONOUS) - Transfer data component DB240 to your own application - Initialise measured value data components (standard: DB220-235) - Transfer functional component FB210 or FB211 and/or FB212 into your own application Note: The applied functional components must be called up in every program cycle 7 Transfer components to AG 4.
Setup PROFIBUS FMS services From the point of view of the application process (S5 program), the communication system represents a group of services, the so-called FMS services. Each slave must provide duty services or can provide additional optional services.
Setup Communication reference KR A communication relationship is addressed by a local short designation, the communication reference KR. Several communication relationships can be created by the master. Local and external Service Access Point LSAP For communication, several service access points are available on both sides. In the KBL, the points where the messages pass must be explicitly stated. VEGACOM 557 PROFIBUS has more than 6 Service Access Points LSAP = 0 … 5.
Setup Basic planning 1. Menu: Init –> Edit Here, the basic initialisation, i.e. the input of the communication processor type (here CP5431) and the name of the planning data base as well as the file names for documentation output, is carried out.
Setup Basis-SSNR: - The basic interface number is required exclusively for SIMATIC components. Sectors of 4 interfaces are always reserved (adjustment range: 0, 4, 8 … 254) Number of interf.: - This parameter indicates how many interfaces (tiles) are accessed (adjustment range: 1 … 4) Module size: - Information on the storage capacity of the storage module. In addition, the generation date and the system identification can be saved.
Setup Number of external active stations: - Number of active stations not acquired in the topology file. This adjustment is necessary for the calculation of the bus parameter block. Max. participant address (HSA): - This is the highest bus address of an active bus participant. Baud rate: - The baud rate of the transmission speed. Default SAP: - On receipt of a telegram without Destinations-SAP number, the CP dials the Default SAP. No.
Setup 4. Menu: Network –> Network survey The network survey shows all database files belonging to a network and thus knots, in a list.

Setup Unconfirmed orders: - This field remains empty as this is reserved for the service "Indicate variable" and this is no Gateway function. Local LSAP: - The Service Access Point (SAP) for the CP5431. With MSAZ (Master-Slave acyclical) connections this value is set automatically to the Poll-SAP 58. Strange LSAP: - This is the SAP from VEGACOM 557 Gateway. The values 0 … 5 are permitted. Strange L2 address: - The instrument address of VEGACOM 557 Gateway.
Setup Transmission of the data base to CP Menu: Load –> CP data base transfer –> FD-CP If the CP parameter setting is finished, the data base must be transferred to the communication processor: - provide connection PC/programming device with CP5431 - stop CP with "Load –> CP Stop" - transfer parameter data base to the CP: Load –> CP data base transfer –> FD-CP - set CP to operating condition with "Load –> CP Start" Important: The new data base is only active after switching off the voltage supply of the CP
Setup Dat administration: Bit 4: Data acceptance running Bit 5: Data transfer being effected Bit 6: Data acceptance being effected Bit 7: Disable data block Failure message: 0: No failure 1: Wrong type information in the functional component 2: Storage area not available 3: Storage area too small 4: Delayed acknowledgement 5: Failure in the indication word 6: Invalid source/destination parameters A: Connection error B: Handshake error C:System error D:Blocked data block E: Order cannot be processed F: Conne
Setup FB245: RECEIVE component The functional component FB245 gives a receive order to the CP. A difference is made between the orders RECEIVE and RECEIVE_ALL. With RECEIVE_ALL (A-NR is 0) receipt data of individual emission orders are received and the order RECEIVE_ALL is recommended here to read in measured values. The information in which data component the received data should be saved, was provided previously with the transmission order. Therefore no further parameters are necessary for RECEIVE_ALL.
Setup FB249: SYNCHRONOUS component By calling up this component, the AG-CP interface is initialised. Here the max. block size is stated, which can be exchanged between AG and CP when calling up a functional component. In this case, the block size must be 5 (BLGR=5: 256 Byte block size). FB249 must be called up in the organisation components OB21 and OB22.
Setup Measured values from DISBUS On DISBUS up to 15 bus participants can be connected, whereby each DISBUS participant provides less than 16 measured values (between 4 and 7 measured values). The bus addresses 1 … 15 must be configured on the VEGAMET instruments. Bus address 0 is not permitted, i.e. the measured values are between the second measured value block (for VEGAMET with bus address 1) and measured value block 16 (VEGAMET with bus address 15).
Setup DB240: Basic settings In this DB, the basic settings and order blocks for CP5431 are determined. Here, only the Start-target DB (data word 0) may be modified. All other parameters may not be modified. Start-target DB: - By this, when using FB210 (read in all measured values) the first data component for saving the measured values can be stated. Since 16 measured value blocks are read in, 16 data components must be reserved by the Start-target DB.
Setup Saving of measured values blocks in measured value data components For saving the measured values, the data components DB220 to DB235 are set as a standard feature. The Start data component can be set in DB240 in DW0 (standard: 220). The next 16 data components must be reserved for the measured values.
Setup Assignment list Menu: Editor –> Assignment list (F7 key) The functional components FB210 and FB212 require operating variables (marker words). Symbolic words were assigned to these variables, so that the index word address can be modified easily if the stated index words (MW10 and MW 252) are already used in your application. Seq. Datei: C:MESSW_Z0.SEQ Zeile: 1 Operand Symbol comment MW 10 MW_BLKNO meas.
Setup FB210: Read in all measured values With this functional component, all 256 measured values (16 measured value blocks) are read in. Important information: The interface number and the order number must be adapted to your application if necessary. These values relate to the values set in the CP connection planning. Call: The functional component must be called up in every program cycle.

Supplement 5 Supplement 5.1 General information on PROFIBUS Note: This chapter is an excerpt of the PNO documentation PROFIBUS, and is to be used only as an informational aid.
Supplement Basic properties of Profibus FMS and Profibus DP PROFIBUS determines the technical and functional properties of a series field bus system, through which distributed, digital field automation instruments in the lower (sensor/actuator level) up to the medium (cell level) power range can be connected. PROFIBUS distinguishes between Master and Slave instruments. Master instruments determine the data traffic on the bus.
Supplement Logic Token ring between the master instruments PLC PLC PROFIBUS M Sensor Sensor Drive M Actor Sensor Drive V Transmitter Passive stations, Slave instruments Hybrid bus access procedure Therefore, the Profibus access procedure includes the Token-Passing procedure for communication among complex bus participants (Master), and underlies the MasterSlave procedure for communication of the complex bus participants with low-expenditure peripherals (Slaves).
Supplement 5.2 Special information on PROFIBUS-FMS PROFIBUS-FMS enables the communication among automation devices as well as the communication of the automation devices with the intelligent field devices. Here the possible functionality is more important than a short system reaction time. In many applications the data exchange is mainly made acyclically on request of the application process.
Supplement The image of the functions of VFD to the real device is provided in the PROFIBUS communication model by the Application Layer Interface (ALI). Image 4 shows the correlation between the real field device and the VFD. In this example, only the variables pressure, level and temperature are part of the VFD and can be read and written via the two communication relationships. All communication objects of a PROFIBUS participant are entered in its own local object directory.

Supplement A parity bit can follow the last data bit which is used for detection of transmission errors. The parity bit ensures that with - EVEN parity always an even number of bits - ODD parity always an odd number of bits is transmitted. The main characteristics of an RS 232 interface are - reduced cable length (max. 15 m to 9600 baud) - low data rates (max. 19200 baud) - only point-to-point connection A so-called handshake can be used to release or interrupt the data transmission.
Supplement The interface RS 485 represents an extension of the RS 422 concept to a bus-compatible system, whereby the physical differences are negligible. The bus system can include up to 32 participants, i.e. 1 master and 31 slaves. A protocol ensures that at any time a maximum of one participant is active as a transmitter, while all others are switched to a passive state. For transmission and reception, only one cable pair is required, which is run in an alternating cycle.
