Product description 1 Product description 1.1 Application 1.2 Configuration With VEGACOM 557 an efficient interface converter (Gateway) is available. It is used for VEGA specific protocols of the DISBUS and LOGBUS into standard data formats. The component VEGACOM 557 is designed in 19" technology with 5 TE width (1 TE = 5.08 mm) acc. to DIN 41 494. It can be used: - in carrier BGT 596 - in VEGALOG 571 carrier BGT LOG 571 - in housing type 505.
Product description 1.3 Function Communication process DISBUS The data communication between VEGACOM 557 and the communication processor CP 524/525 is only made if initiated by the PLC which can call up the requested information via special commands. The data from DISBUS/LOGBUS are first written in a buffer memory in VEGACOM 557. The new generation of VEGAMET 500 signal conditioning instruments can transfer measured data and status information via the DISBUS to VEGADIS 174 indicating instruments.

Setup 4 Setup 4.1 Check list The check list gives a short overview on the activities required for configuration. A detailed description of the individual items is made in this document. • Equip VEGACOM 557 with the additional board S5 (for communication with procedure 3964 /R). • Equip communication processor CP with the necessary interface (RS232, RS422/485 or TTY). Set interface number • Adjust VEGACOM DIL switches and hook switches. Interface parameters must be adjusted.
Setup Basic pattern To create a new program, you have to enter the file and system name in the basic pattern. As component, you have to choose RK (for computer link).

Setup Order indicating values After F1 selection (see previous pattern) the adjustment of the order number is expected, here e.g. 1. For parameter setting of order number 1, function key F5 (Order Progr.) must be selected: In this pattern it will be determined that order no. 1 is a Fetch order (fetch data). The data to be received should be fetched by source data component 3 from source word address 0. Coordination markers are not required. -> CHOICE -> ORDER BLOCK -> O R D E R P R O G R .
Setup Order switching condition relay The relays are saved in data component DB5. Therefore it is necessary to enter this data component in the order. The order number has been set to 2 as we assumed that already an order for reading the measured values is available. -> CHOICE -> ORDER BLOCK -> O R D E R P R O G R .

S5 functional component 5 S5 functional component For the STEP 5 user program, internal functional components (HTB handling components) HTB SYNCHRON, HTB FETCH and HTB RECEIVE are required. To call up the internal function components, these must be loaded first from the automation device AG S5. The menu selection is then as follows: Object > Components > Transfer > AG file. 5.1 Synchron order After the starting-up phase, the CP expects a SYNCHRON order.
S5 functional component 5.2 Handling components for reading in of data (indicating values) For reading in the indicating values from the VEGAMET instruments and saving them in a PLC data component, the handling component HTB FETCH is necessary to place orders and the HTB RECEIVE to fetch and save data. Handling component FETCH The FETCH component gives the order to the CP to fetch data of a communication partner. The receipt of the data however is carried out by the component RECEIVE.
S5 functional component Handling component RECEIVE This component receives the data of the stated order number. Difference is made between the two function modes: • RECEIVE -All data can be received for each individual order.
S5 functional component 5.3 Reading in data (indicating values) The indicating values are saved in a PLC data component of the S5 data memory. It is obligatory to state DB3 in the programming package COM 525 when determining the orders for measurement loops 1 … 128 and DB4 for measurement loops 129 … 255. See also chapter 5.1. Here also the data destination, e.g. source data component 3 from source word address 0 is stated.
S5 functional component Status values: STAT Meaning 00 H Valid value 01 H Simulated value 80 H Value not available FF H General error Calculation of the data word address The data word address of the first indicating value of VEGAMET to address is determined as follows: Data word address = VEGAMET address • 14 + ZANF (Fetch) for the parameter ZANF from Fetch order ZANF (Fetch) = 0 results from: VEGAMET (DISBUS): Data word address = VEGAMET address • 14 – Source word address • 2 for VEGAMET address
S5 functional component Saving of VEGALOG data in a PLC data component 2 data words (4 bytes) are required per indicating value. These are saved in the PLC data component DB as follows: Image 2 VEGALOG functional component no. = 1 … 254 (source word address 0) DW 0 HB LB ME STAT VEGALOG functional component no. 1 2 HB LB ME STAT VEGALOG functional component no. 2 4 HB LB ME STAT VEGALOG functional component no.

S5 functional component Parameter setting of the RECEIVE component The information on the data destination, parameter : ZTYP, DBNR, ZANF and ZLAE are irrelevant as this information was already defined in the programming package COM 525 with the order determination. SSNR: A-NR: ANW: ZTYP: DBNR: ZANF: ZLAE: PAFE: The interface number corresponds to the switch positions in the CP.
S5 functional component Call up of the Fetch and Receive component for the indicating values The program reads in the indicating values for the VEGAMET instruments (DISBUS) or VEGALOG instruments (LOGBUS). The Fetch order was determined in the programming package COM 525 with order number 1. The statements on the data destination had been carried out in the programming package with the order determination.

Supplement 6 Supplement 6.1 Short description of the standard interfaces RS 232, RS 422 and RS 485 Hardware handshake: The receiver controls via its handshake outputs DTR or DSR the handshake inputs CTS or DSR of the emitter. The standard interfaces RS 232, RS 422, RS 485 used in VEGACOM 557 depending on the version, transmit the data serially and asynchronously in bit form. Thereby the conditions "0" and "1" are transmitted by defined voltage levels.
Supplement The interface RS 422 transfers the data as voltage difference between two corresponding cables. Signal earth as grounding is not required. One pair of wires is required for the transmitting as well as for the receipt signal, consisting of an inverted and a non-inverted signal cable. Possible common-mode interferences cause a symmetric shift of the voltage level and cannot deteriorate the useful signal.
