2 PROFIBUS Overview PROFIBUS (PROcess FIeld BUS) is a vendor-independent, open fieldbus standard for a wide range of applications in manufacturing, process and building automation. Vendor independence and openness are guaranteed by the PROFIBUS standard EN With PROFIBUS, devices of different manufacturers can communicate without special interface adjustments. PROFIBUS can be used for both high-speed time critical transmission and extensive complex communication tasks. Version 2.0 / july 2000 / page 2/16 applicom, open industrial communication concept 143

3 PROFIBUS PROFIBUS standard EN specifies the functional, electrical and mechanical characteristics for a serial transmission fieldbus. The protocol architecture is oriented to the OSI (Open System Interconnection) reference model. PROFIBUS is located both at the cell supervisor level named Layer 7 (application layer) and at the field network level named Layer 1 (physical layer) and Layer 2 (Data Link layer). The applicom board connected to the PROFIBUS fieldbus can simultaneously manage 5 different types of communication messagings, depending on the connected devices: " PROFIBUS-DP Class 1, Class2 - Master/Slave modes " FDL for SIEMENS Simatic S5 - Master mode " PROFIBUS-FMS - Client & Server modes " MPI for SIEMENS Simatic series - Master mode " Protocol S7 on PROFIBUS for SIEMENS Simatic series - Master mode Reminder Master devices determine the data communication on the bus. A master can send messages without an external request when it holds the bus access rights (the token). Masters are also called active stations in the PROFIBUS protocol. Slave devices are peripheral devices. Typical slave devices include input/output devices, valves, drives and measuring transmitters. They do not have bus access rights and they can only acknowledge received messages or send messages to the master when requested to do so. Slaves are also called passive stations. Version 2.0 / july 2000 / page 3/16 applicom, open industrial communication concept 144

4 PROFIBUS-DP Master and Slave modes The PROFIBUS DP (Decentralized Peripherical) fieldbus is based on the European standard EN (Part 2). PROFIBUS-DP is designed especially for communication between automation control systems and distributed I/O at the device level. The Master and Slave modes are available simultaneously on the applicom interface. Master mode applicom as a DP Master interface includes Class-1, Class-2 and Multimaster management. PROFIBUS-DP telegrams can be used to transfer up to 244 bytes of data per telegram and connect to devices of address from 0 to 126. Each DP device has specific parameters such as device version, baud rate, data format, I/O length, user parameters, etc. These parameters are stored in a file with.gsd extension. The GSD file is provided by your manufacturer and is required for device configuration. The format of the GSD file is described in the standard (EN 50170, volume 2, PROFIBUS). The applicom configuration tool is able to import GSD files allowing you to edit and modify the user parameters to initialize PROFIBUS devices.

6 PROFIBUS-DP Master & Slave modes Slave mode This functionality is available on PCI2000PFB and PC104PFB applicom boards. It provides the data exchange between an applicom interface and DP Master(s) on the Profibus network. The applicom interface in DP Slave mode behaves as a standard slave device. This device could be access from the DP Master on the network as well as the client applications on the local machine through the applicom DP Master functionality. The GSD description files are provided and installed with the product. The size of Input/Output data area could be configuring from 0 to 244 bytes. The applicom interface can ensure data consistency up to size of 122 bytes (the data consistency insures the data coherence of word, double-word and floating-point types). The statuses of applicom functions guarantee refreshing of data with the remote Master as long as it sets the Bus Time-out (watchdog control) parameter.

7 PROFIBUS FDL Master mode S5 messaging on Profibus, developed by Siemens France, was designed especially to open Siemens SINEC L2 PLC s (based on FDL) to calculator PC based applications. S5 messaging uses PROFIBUS layer 2 called Fieldbus Data Link (FDL) to send and receive S5 requests. The FDL S5 messaging on applicom interface is Master type (Active Station) and as a client it manages exchanges with S5 PLCs such as: " 95U, " 115U (942, 943, 943B, 944, 944B, 945), " 135U (928, 928B), " 155U (946, 947, 948, 948B) Please contact us for other supported couplers. A Function Block (FB100) is provided for each type of Siemens S5 CPU. You have to downloaded it into the PLC program in order to ensure S5 messaging communication.
