Product description VEGACOM 557 on DISBUS VEGAMET series 500/600 signal conditioning instruments transmit via the DISBUS cyclically measured data and status information, so called PC/DCS telegrams. VEGACOM 557 receives as participant on the DISBUS these data and makes them available (in buffer memory) for collection via the Pr ofibus DP. DISBUS VEGACOM 557 on LOGBUS Data are exchanged continuously on the LOGBUS between the individual components of VEGALOG 571.
Product description VEGACOM 557 on Profibus DP The data communication between VEGACOM 557 and Profibus DP-Master is only carried out if initiated by the master , which can enquire the requested information by means of special control commands. The data from DISBUS/LOGBUS are first written in a buffer memory of VEGACOM 557. The data set is transferred from this buffer memory into a process image.

Measurement loop in VEGAMET/VEGALOG 4 Measurement loop in VEGAMET/VEGALOG Generally a measurement loop in VEGAMET/VEGALOG processing systems is structured as follows: A sensor delivers the sensor value to the input of the processing system. This sensor value is then further processing in the processed system (.e.g. empty/full adjustment, linearisation ...). The processed values are outputted (e.g. via current outputs, relay outputs ...). The PC/DCS output is available as gateway for VEGACOM 557, i.e.
Measurement loop in VEGAMET/VEGALOG 4.1 PC/DCS output Max. 255 PC/DCS outputs are available, depending on the processing system. The configuration or parameter setting of the PC/ DCS outputs is done with the adjustment software VVO or via keyboard (VEGAMET) in the processing system. Several PC/DCS outputs can be allocated to each measurement loop. This enables the possibility of transmitting the measured value, e.g. as “Percentage value“ and “Scaled“, e.g. in “Liters“ to the Pr ofibus master.
Measurement loop in VEGAMET/VEGALOG Examples of parameter settings: parameter, unit Percent is chosen as parameter and 0.0% as unit. The measured value 0.0 … 100.0 % is transferred with these parameters as PC/ DCS value 0 … 1000. Percent is chosen as parameter and 0.00% as unit. The measured value 0.00 … 100.00 % is transferred with these parameters as PC/DCS value 0 … 10000.
Transfer of measur ed value 5 Transfer of measured value As DP norm slave, the VEGACOM 557 DP gateway is either configured with 50 Byte consistent input data and 2 Byte consistent output data or with 6 Byte consistent input data and 6 Byte consistent output data (see chapter „6 Operating mode VEGACOM 557“). The DP master transmits via the inputs control information to VEGACOM 557, to which VEGACOM 557 r esponds accor dingly, making the data available to the DP master as input information. 5.
Operating mode VEGACOM 557 6 Operating mode VEGACOM 557 Two dif ferent operating modes ar e available for VEGACOM 557. Depending on the operating mode, VEGACOM 557 reserves a different number of input and output bytes in the Profibus-Master. 6.1 Mode 50E2A In this mode, VEGACOM 557 reserves 50 input bytes and 2 output bytes. The Profibus-Master has to process 50 Bytes of data consistently . How it works A control command and a block number (1 byte each) are written into the 2 Byte output data.

Supplement C Supplement C 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 C 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 C Logic token ring between the Master instruments PLC PLC PROFIBUS M Sensor Sensor Drive Actor Sensor M V Drive Transmitter Passive stations, Slave instruments Hybrid bus access procedure Therefore, the Profibus bus access procedure includes the T oken-Passing pr ocedure for communication among complex bus par ticipants (Master), and underlies the Master Slave procedure for communication of the complex bus participants with low-expenditure peripherals (Slaves).
Supplement C 2 Special information on Profibus DP Diagnostic functions Profibus DP is designed for quick data exchange on the sensor/actuator level. Here, central control instruments (such as e.g. PLC) communicate via a quick, serial connection with decentralised input and output instruments. The data exchange with these decentralised instruments is mainly done on a cyclical basis. The central control (Master) reads the input information of the Slaves and writes the output information to the Slaves.
Supplement C Each Pr ofibus DP system consists of dif ferent instrument types. Depending on their individual tasks, the instruments can be classified into three types: DP Master class 1 (DPM1) This is a central control, exchanging in a predetermined message cycle information with the decentralised stations (DP Slaves). Typical instruments ar e e.g. PLC, CNC or RC. DP Master class 2 (DPM2) Instruments of this type are programming, planning or diagnostic instruments.
Supplement C DP Master (DPM2) DP Master (DPM1) DP Master (DPM1) PLC CNC Profibus DP Actor Sensor decentralised inputs and outputs decentralised inputs and outputs DP Slaves Several Masters can (reading) access to the data of the DP Slaves Profibus DP multimaster system Data traffic between DPM1 and the DP Slaves or planning instruments The data traffic between the DPM1 and the allocated DP Slaves is carried out automatically by the DPM 1 in a predetermined, recurring sequence.
Supplement C Function Meaning Get_Master_Diag Reading of the diagnostic data of the DMP1 or the collective diagnostics of the DP Slaves Loading or reading of the complete configuration data of a DPM1 and the respective DP Slaves Download / Upload group (Start_Seq, Download / Upload, End_Seq) Act_Para_Brct Act_Param DPM1 Activation of the bus parameters together for all responded DPM1 instruments. Activation of parameters or modifications of the operating condition on the responded DPM1 instrument.
Supplement C 3 Short description of the interface RS 485 The standard interface RS 485 used in VEGACOM 557 Profibus DP transmits the data serially and asynchronously in bit form. Thereby the conditions "0" and "1" are transmitted (without ground reference) by defined voltage differences between two cables. Usually, the dif ferential voltage of -3...-6V corresponds to a logic "1". A logic „0“ is shown by a differential voltage of +3...+6V.
