Device Profile

Bus Access Protocol
The PROFIBUS bus access protocol is implemented by OSI layer 2. This protocol also includes data security and the handling of the transmission protocols and messages. The Medium Access Control (MAC) specifies the procedures which determine when a device is permitted to transmit data. A token passing procedure is used to handle the bus access between master devices, and a polling procedure is used to handle the communication between a master device and its assigned slave device(s). The token passing procedure guarantees that the bus access right (the token) is assigned to each master within a precisely defined time frame. The token message, a special message for passing access rights from one master to the next master, must be passed around the logical token ring - once to each master - within a specified target rotation time. Each master executes this procedure automatically. The polling or master-slave procedure permits the master, currently in possession of the token, to access its assigned slaves. The figure below shows a possible configuration The configuration shows three active devices (masters) and six passive devices (slaves). The three masters form a logical token ring. When an active device receives the token message, it can perform its master role for a certain period of time. During this time it can communicate with all assigned slave devices in a master-slave communication relationship, and a DPM2 master can take the initia-

Multi-peer Communication Broadcast Communication Multicast Communication
In addition to logical peer-to-peer data transmission, PROFIBUS DP provides multi-peer communication (broadcast and multicast). In the case of broadcast communication a master device sends an unacknowledged message to all other devices (masters and slaves). In the case of multicast communication a master device sends an unacknowledged message to a predetermined group of devices (masters and slaves).

Diagnostic functions

Extensive diagnostic functions defined in PROFIBUS DP enable the fast location of error at slave devices. Diagnostic messages are transmitted over the bus and collected at the master. Three levels of diagnostic messages are defined: Messages concerning the general operational status of the whole device, e.g. over temperature, low voltage. Messages indicating that an error is present in a specific I/O range of a device, e.g. an 8-bit output module. Messages indicating an error at a given input or output, e.g. short circuit on Output 5.

Protection mechanisms

PROFIBUS DP provides effective protection functions against parameterization errors or failure of the transmission equipment. Time monitoring is provided both at the master and the slave devices. The monitoring interval is specified when the system is configured. The PROFIBUS DP Master monitors data transmission of the slaves with the Data-Control-Timer. A separate control timer is used for each slave. This timer expires if response data is not correctly transmitted by the slave within the monitoring interval. The user is informed when this happens. If the automatic error reaction (Auto-CLEAR) has been enabled, the PROFIBUS DP

Monitoring Time

Section 1-2

master exits its OPERATE state, switches the outputs of all assigned slaves to the fail-safe status and changes to the CLEAR state. Monitoring at the Slave Slave devices use a watchdog to detect failures of the master or the bus. If data communication with the master does not occur within the set watchdog time interval, a slave automatically switches its outputs to the fail-safe mode. Also, access protection is provided for the inputs and outputs of the slaves operating in multi-master systems. Only authorized masters can access their slaves.

OFF-LINE STOP CLEAR

Network Operation Modes
PROFIBUS DP distinguishes four different network operation modes: Communication with all PROFIBUS DP participants (masters and slaves) is stopped. The Master ceases to access the PROFIBUS network. Communication between the master and its slaves is stopped. Only communication between the master and other masters is still possible. The master tries to set parameters, check the configuration, and perform data exchange with its associated slaves. Data exchange involves reading the inputs of the PROFIBUS DP slaves and writing zeros to the outputs of the slaves. The master exchanges data with its assigned slaves, inputs are read and outputs are written. Also, the master cyclically sends its local status to all its assigned PROFIBUS DP slaves (using a broadcast message). If an error occurs during the data exchange phase of the master, the AutoCLEAR function determines the subsequent actions. If this function has been disabled, the master remains in the OPERATE mode. If the function has been enabled, the master automatically changes the network to the CLEAR mode, in which the outputs of the assigned PROFIBUS DP slaves are switched to zero, i.e. the fail-safe state. The master continues to read the inputs of the slaves.

OPERATE

Auto-CLEAR

Fail-safe State

In order to operate a PROFIBUS network, each master in the network needs to be configured. This process of PROFIBUS Master configuration involves: setting up the network topology, i.e. assigning the slave devices with which the master will be exchanging data, defining the parameterization data, which the master will send to each of the slave devices, before process data exchange can commence defining the configuration data, i.e. defining the process data, which will be exchanged, setting up the bus parameters, which define the baud rate and the bus timing parameters. downloading the configuration setup to the master device.

Configuration Technology

The configuration process is usually facilitated by a special Computer based program, often referred to as a Configurator. The Configurator requires special configuration files, defining the configuration options for each device, which is to participate in data exchange. The files must be provided by the manufacturer of the device.
Two types of configuration technology exist: Configuration technology based on FDT/DTM technology Configuration technology based on GSD-files FDT/DTM Concept
The FDT/DTM concept specifies the interfaces between the engineering systems called Field Device Tools (FDT), and the device-specific software components called Device Type Managers (DTM). The FDT/DTM concept separates the device dependent functionality (which is in the DTM) from the application. It provides separate interfaces for device configuration, monitoring and maintenance solutions, which before largely depended on the manufacturer of the application. Because of this concept, FDT/DTM technology is not limited to PROFIBUS applications. In concept, any type of network can be configured and accessed, provided the appropriate DTMs are available. CX-Profibus is an example of a FDT container application. It is described in detail in the following sections.

GSD file Technology

The older and most commonly used configuration technology is the based on GSD files (General Slave Data file). A GSD file is a text file, containing the characteristic features and configuration options of a device. The device data base file of each device is loaded in the configurator and downloaded to the master device. GSD files are usually supplied with a unit, or can be downloaded from the Internet, either from the manufacturer's site, or from the GSD library of the PROFIBUS Nutzer Organisation at http://www.profibus.com.

GSD File Language

The language used in the GSD file is indicated by the last letter of the file extension, *.GS?: Default = GSD English = GSE German = GSG Italian = GSI Portuguese = GSP Spanish = GSS The GSD files are prepared individually by the vendor for each type of device, according to a fixed format. Some parameters are mandatory, some have a default value and some are optional. The device data base file is divided into three parts:

Section 3-1

This section discusses the operational aspects of using the PRT1-SCU11 and the configuration software. The section has been setup, to follow the general process flow of setting up and configuring a network, downloading the configuration, and operating the PROFIBUS network, the Compoway-F, K-Format, Host Link or Memobus network. The PROFIBUS Master can communicate with the PRT1-SCU11 using fixed communication block and/or Free Communication blocks. In case Error messages are displayed, while using CX-Profibus, refer to the appropriate manual for more information on errors. Note 1. The maximum number of devices is 15. 2. The maximum of modules is 18. This number consists of 15 fixed communication blocks, 1 write, 1 read and 1 operation Free Communication block.

PROFIBUS Communication

As mentioned in the previous section there are two ways of PROFIBUS communication. Communication with fixed communication blocks and Free Communication blocks.
Fixed Communication Blocks Example
Fixed communication blocks are pre-defined blocks of data to be read/written from/to a device. Fixed communication blocks can not be changed. The most common data can be read/written using fixed communication blocks. For an E5ZN connected to the PRT1-SCU11 a 2-channel basic fixed I/O block defines the data transfer of 1 Setpoint Value for each channel and 1 Process Value for each channel between the PROFIBUS Master unit and the E5ZN through the PRT1-SCU11. Free communication blocks are sent directly to the device connected to the PRT1-SCU11. The PRT1-SCU11 does not interfere with the data contents of the block. This allows Free Communication blocks to be used to access data in a device which can not be accessed through fixed communication blocks. Free Communication Blocks can be used for Compoway-F and the K-Format protocol. Flexible communication blocks are defined for the Memobus protocol and are a mix between the fixed blocks and the Free Communication blocks. The flexible communication blocks will contain 3 input words and 3 output words, for each of which a target register in the Varispeed F7 Inverter can be defined. The maximum amount of PROFIBUS data the PRT1-SCU11 can handle is 100 words input data and 100 words100 output data. If more capacity is needed an extra PRT1-SCU11 is required to access additional devices. Note As per PROFIBUS DP definition the I/O data words are sent in Big Endian format, i.e. the high byte is sent first.

For the K-Format protocol one Free Communication Block is available, which has however, a different format as compared to the Free Communication Block for Compoway-F. The one Free Communication block allows implementation of Read, Write and special Operation type of commands.
Free Communication Block Format
The Free Communication block reserves 3 words of input data and 3 words of output data. The output format is shown below.
Device address 1 byte Reserved 1 byte Command type 1 byte Parameter Number/ Command code 1 byte Data 2 byte
The table below lists the message parameters.
Message parameter Device address Reserved Command type Description The address number of the target device. A reserved byte, which will be ignored by the PRT1-SCU11 A command type code 1 = Read command 2 = Write command 3 = Special command 4 ~ FF = Invalid command Refer to the E5AK / E5EK Operation Manual. In case the Command type is set to 1 or 2, use the Parameter number to specify the parameter to be read or written. In case the Command type is set to 3, use the Command code to define the Special Operation. Data to be written. The PRT1-SCU11 will ignore this part in case of a Read command or a special operation command.

PROFIBUS Diagnostics

Section 3-7
The PRT1-SCU11 provides extended diagnostics over PROFIBUS to notify the PROFIBUS DP Master of the Units status and the status of the RS-422A/ RS-485 communication. These extended diagnostics are sent to the Master unit via a PROFIBUS Diagnostics message. These messages are only sent up on occurrence of the error or status event. A PROFIBUS Diagnostics message will contain 6 standard diagnostics bytes, followed by the Extended diagnostics bytes, in case any extended diagnostics data is available. The extended diagnostics bytes as produced by the PRT1SCU11 are shown below.

Auxiliary RS-232C interface

Section 3-8

The PRT1-SCU11 provides an RS-232C interface, behind a cover lid on the front of the Unit. This interface allows a user to connected an IBM compatible computer with a serial port and send and receive data to a Compoway-F, or KFormat device using the software package CX-Thermo. Equally, when Memobus has been selected as the protocol, the RS-232C interface can be used to transfer commands from CX-Drive and the Varispeed F7 Inverter.

Using CX-Thermo

Before using CX-Thermo DIP-switch 4 must be set on, a group of four DIPswitches is located on the front of the PRT1-SCU11 Unit. Note CX-Thermo is not shipped with the PRT1-SCU11. When DIP-switch 4 is switched on, the PRT1-SCU11 will stop the data exchange with the PROFIBUS Master. The PROFIBUS DP interface will stay inactive until switch 4 is switch off. When DIP-switch 4 is set on: The diagnostics indicates Slave Not_Ready. FERR LED is switched off. COMM LED starts flashing. FCOM start flashing. BF LED is switched off. To connect with the PRT1-SCU11 use an auxiliary RS-232C compatible interface on an IBM compatible computer and a standard Omron RS-232C PLC cable e.g. (CS1W-CN226). Note The interface connection is not galvanically isolated. The baud rate settings are the same as used for the Compoway-F interface, as set through the associated DIP-switches.

RS-422A / RS-485 LEDs FCOM Not lit FERR Not lit Description No communication over RS-422A / RS-485. Probably a broken wire. Unit has not initialized. Not all devices configured in the PRT1SCU11 are communicating. No power connected to the Unit. No PROFIBUS communication.

Communication with RS-422A / RS-485 devices fails, the Unit is unable to establish communication with all devices. Solution Check all cables and connections. Switch the Unit off and on, make sure the network configuration has been downloaded. Check Compoway-F, Host Link, K-Format or Memobus addresses, baud rate settings. If baud rate settings are changed a restart must performed Switch power to the Unit. The hardware does not correspond with the configured network in the software. -
