AS-i/PROFIBUS Gateway

General Information

4 General Information

This operating instruction is for use with the following devices of the Pepperl+Fuchs GmbH:

• VAG-PB-KF-R4 The AS-i/PROFIBUS-Gateways serve to connect the Actuator-Sensor-Interface to

the PROFIBUS-DP. A gateway represents the master for the AS-Interface and the slave for the PROFIBUS.

The AS-i/PROFIBUS-Gateway is constructed as a PROFIBUS DP slave only. It supports all PROFIBUS transmission rates up to 12 MBaud.

All AS-Interface functions can be called via the Profibus. There are three operation modes for the data exchange with Profibus-DP: the easy mode, the advanced mode and the professional mode. In the easy mode, the gateway uses a fixed I/O-configuration for the Profibus and the gateway can be put into operation very easily without further parameterization on the Profibus master. In the advanced mode, the size of the I/O window can be matched to the actual structure of the AS-i network. The AS-i master is configured by the Profibus master. During operation, AS-i parameters can be transmitted to the AS-i slaves. Also the mini-PLC AS-i Control is accessible. All AS-i Control functions are available (program download, upload, start, stop, read and write user memory). The professional mode is the advancement of the advanced mode. With its management channel it is additionally possible to execute further AS-i commands via Profibus. Furthermore you can operate the advanced AS-i diagnosis via Profibus.

The scope of delivery includes several GSD-files to ensure the easy putting into operation in each operating mode. In contains also the Siemens type files version 4.0 (German) and 5.x.

All devices contain the integrated mini-PLC AS-i Control for the fast distributed preprocessing of AS-i data. Furthermore advanced AS-i diagnosis functions are implemented to locate sporadically occurring configuration errors and to judge the quality of the AS-i communication.

All devices are delivered together with the AS-i Control Tools, a Windows software for the easy putting into operation of the AS-Interface and the programming of AS-i Control. The software communicates via the serial interface of the PC without additional expensive hardware. Merely a Profibus converter is needed to connect the RS232 interface of the PC with the Profibus interface of the AS-i/PROFIBUS Gateway.

If no PC is available the putting into operation, troubleshooting and setting up of the AS-i parameters can be accomplished with the use of two push-buttons, the display and the LEDs directly on the device.

5.3 Mounting and Connections

5.3.1 Mounting

The KF… design of the gateway can be mounted on a 35 mm DIN rail in accordance with EN 50022 and facilitates electrical connection through the "Power Rail". It is also possible to use the more conventional and expensive method of cable connections to terminals with this design.

The gateway is snapped directly onto the DIN rail. When using the power rail, an electrical connection is automatically made (to the AS-i Bus) by snapping the gateway onto the rail leads..

5.3.2 Connection via the Power Rail

The PR05 power rail is an insert for the DIN rail in accordance with EN 50 022. The UPR 05 is delivered with the appropriate DIN rail.

The 5 pin version of the power rail must be used during the establishment of AS-interface circuits. Two of the five power rails make up the AS-i bus.

5.3.3 Device Terminal Connections

In addition to or in combination with power rail connections, the KF… designs can be conventionally connected by means of removable device terminals. The terminal arrangement is shown below.

The device terminals consist of screw type cable piercing terminals which allow for the connection of 14 AWG cables (2.5 mm²). The connectors are 3 pin connectors; they can be keyed to prevent connection errors.

Removable terminals simplify the assembly of the switch encloser and allow for the replacement of components without taking the system off line.

5.3.4 Gateway Power Supply

The gateway is supplied through the AS-i circuit. A connection to the AS-i cable is established by means of the power rail and/or with the device terminals. The terminal layout is displayed in the diagram above.

It is important to note when using the power unit that these AS-Interfaces are compatible and have the necessary decoupling coils.

5.4 The PROFIBUS Interface

The serial interface is a 9 pin SUB-D connector. It is located on the right side of the device front. The other possibility is to use the device terminals. The wiring is shown in the picture below:

AS-i/PROFIBUS Gateway

Operating the AS-i/PROFIBUS Gateway

6 Operating the AS-i/PROFIBUS Gateway

6.1 Master Start-Up

After powering on, all segments of the figure display and all LEDs light up for approximately one second (self-test). Afterwards, the LEDs display the condition of their respective flags. The LCD displays the condition of the master:

40 Off-line Phase

The AS-i Master initializes—there is no data communication on the AS-i.

If the AS-i circuit is insufficiently powered (“U ASI” does not light up) or there is no communication relationship between the Profibus master and the AS-i/PROFIBUS Gateway, the master remains in the off-line phase.

In configuration mode or when an AS-i Control program is started automatically the device can leave the Off-line phase. In protected mode, if the Profibus communication is interrupted, the AS-i Master switches to the off-line phase after the watchdog time of the Profibus has expired unless an AS-i Control program is running and was started automatically.

41 Detection Phase

Start of the start-up phase, where the system looks for slaves located on the AS-i. The master remains in the detection phase until it finds at least one slave.

42 Activation Phase

Condition at the end of the start-up operation where the parameters are transmitted to all connected and recognized slaves. This enables access to the AS-i slaves’ data connections.

431Start of Normal Operation

In normal operation the AS-i master can exchange data with all active slaves. It transmits management messages and looks for and activates newly connected slaves. During normal operation, the system keeps the maximum cycle time of 5 milliseconds.

6.2 Configuration Mode

The configuration mode serves to configure the AS-i circuit.

In the configuration mode, all recognized slaves are activated even when the desired and actual configurations do not match.

1. Activation phase and the start of normal operation maybe so short that the numbers can not be seen in the display.

AS-Interface

Operating the AS-i/PROFIBUS Gateway

Pressing the “mode” button for at least five seconds switches the master to configuration mode. While in configuration mode, the yellow “prj mode” LED lights up.

The system then displays one after the other all detected slaves at a speed of two per second. If the display is empty, no slaves were detached on the AS-i circuit.

In configuration mode, all recognized slaves are activated except of slave zero. The AS-i Master is in normal operation. There is data exchange between the AS-i Master and all AS-i slaves detected by the master regardless of whether the detected AS-i slaves were projected before.

When delivered the AS-i/PROFIBUS Gateway is in configuration mode.

6.3 Protected Operating Mode

In contrast with the configuration mode in the protected mode there is only data exchange between the AS-i Master and the projected AS-i slaves.

6.3.1 Switching to Protected Operating Mode

You leave the configuration mode by pressing the “mode” button.

Pressing the button shortly:

Exits the configuration mode without projecting the current AS-i configuration.

Pressing the button for more than five seconds:

Exits the configuration mode and projects the actual AS-i configuration. Simultaneously the actual AS-i configuration is stored as nominal configuration in the EEPROM.

If the system detects an AS-i slave with address zero on the AS-i, it can not leave the configuration mode.

In the protected operating mode, only AS-i slaves that are projected and whose actual configurations match the nominal configurations will be activated.

6.3.2 Configuration Errors in Protected Operating Mode

As long as there is no configuration error, the numeric display is turned off while in protected operating mode. Otherwise, the that address a faulty assignment is displayed. A faulty assignment occurs when a slave has been recognized or projected but cannot be activated.

AS-i/PROFIBUS Gateway

Operating the AS-i/PROFIBUS Gateway

If there are more than one faulty assignments the one that was first detected is displayed. Pressing the “set” button shortly displays the next higher faulty address.

Shortly appearing configuration errors are stored in the device (advanced AS-i diagnosis). The last error that occurred can be displayed by pressing the set button. If a short AS-i power failure is responsible for the configuration error the display shows a “39“.

6.4 Assigning an AS-i Address in Configuration Mode

AS-i can be put into operation in a very comfortable manner by using the Windows software AS-i Control Tools (see chapter 9.1)(addressing directly or with the AS-i address assistant).

Furthermore you can use a hand held addressing device. If you don’t have neither a PC nor a hand held addressing device, address assigning

of the AS-i slaves is also possible with the AS-i/PROFIBUS Gateway using the push buttons. How it works is described as follows.

6.4.1 Assigning a Slave Address

(assigning an available address to a slave with address zero) In configuration mode, the addresses of all detected slaves are displayed one after

the other. To display the next higher available operating address, press the “set” button shortly. Each time you press the “set” button, the next available address is displayed.

Chose the displayed address as your target address by pressing the button for more than five seconds. The address display blinks. The master is ready for programming; pressing the “set” button again addresses the connected slave with address zero to the target (blinking address.

Any errors will be displayed by their error codes according to chapter 10. Otherwise, the detected slaves are displayed again as described in chapter 6.2.

6.4.2 Erasing the Slave Address

AS-iIn configuration mode, the addresses of all recognized slaves are displayed one after the other. By pressing and releasing the “set” button, the master displays the next available address. If you press the button for more than five seconds while the address of a detected slave is displayed, this slave is will get the address zero and the display shows “00”.

When you release the button, the display continues to display the detected slaves.

AS-Interface

Operating the AS-i/PROFIBUS Gateway

6.5 Programming the Address in Case of Configuration Errors

6.5.1 Automatic Address Assignment

One of AS-i’s great advantages is the automatic address assignment. If a slave fails, it can be replaced by one of the same type with address zero. The master will detect the replacement and automatically addresses the new slave with the address of the faulty one.

For automatic programming to work, some requirements must be met:

1.The AS-i master must be in the protected operating mode.

2.The “Auto_Address_Assign” release flag must be set.

3.Only one of the projected slaves may not be detected.

If these requirements are met, the AS-i master’s “prg enable” LED lights up and a slave with address zero will be automatically assigned to the operating address of the missing slave.

If the two slaves have different configuration data, i.e. are not of the same type as far as AS-i is concerned, the automatic address assignment will not be carried out.

6.5.2 Manual Address Assignment

If several slaves fail, they cannot be replaced automatically by the AS-i master. You must set their addresses manually. If this should not be done via the Profibus interface (using the AS-i Control Tools) or with a hand held addressing device, you can set them with the push buttons and the figure display of the device.

In protected operating mode, wrong assignments are displayed as errors (see chapter

6.3). By pressing the “set” button, you can display all faulty assignments one after the other. By pressing the “set” button for more than five seconds, you can select the currently displayed address as a potential target address, and the display starts to blink.

If the faulty slave was previously replaced by a slave with address zero, the new slave can now be programmed for the blinking address by pressing the “set” key again. As a requirement, the new slave’s configuration data must match the configuration data for the blinking address.

After the address has been successfully set, the next faulty assignment is displayed and the address assignment can begin from the start. Otherwise, the system displays an error code (chapter 10). When all faulty assignment are eliminated the display is empty.

Operating the AS-i/PROFIBUS Gateway

6.6 Setting of the Profibus Station Address and the Protocol Type

6.6.1 Profibus Station Address

The addressing of the AS-i/PROFIBUS Gateway as a Profibus slave can be done locally at the gateway or via Profibus according to the Profibus norm.

Station addresses from 1 to 99 can be set, when delivered station address 3 is set. For the relocation, both the "set" button and the "mode" button have to be pushed si-

multaneously for at least 5 seconds until the current bus address is shown on the LCD display. With every pushing of the "set" button, the station address can now be increased by 1.

Once the desired Profibus station address is shown on the display, it will be stored non-volatile in the EEPROM by pushing the “mode“ button.

6.7 Error Messages

The system displays error codes for error messages that do not point to faulty assignments on the AS-icircuit. The code numbers are larger than 50 and are therefore outside the slave address range. These codes are described in the appendix, chapter 10.

AS-i/PROFIBUS Gateway

Advanced Diagnostics for AS-i Masters

7 Advanced Diagnostics for AS-i Masters

The advanced AS-i diagnostics serves to locate occasionally occurring errors and to judge the quality of data transmission on AS-i without additional diagnostics tools.

The AS-i Control Tools, Bihl+Wiedemann’s software for the comfortable commissioning of the AS-Interface and the programming of AS-i Control, will include the operation of the Advanced Diagnostics from version 3.0 on.

7.1 List of Corrupted AS-i Slaves (LCS)

To locate occasionally occurring short-time configuration errors the AS-i Masters with advanced diagnostics manage beside the list of projected slaves (LPS), the list of detected slaves (LDS) and the list of activated slaves (LAS) a forth list, the list of cor- rupted slaves (LCS). This list contains entries of all AS-i slaves which were responsible for at least one configuration error since powering up the AS-i master or reading the list. Short-time AS-i power failures are represented in the LCS at the position of AS-i slave with address 0.

With every read access the LCS will be deleted.

The last short-time configuration error can also be displayed on the AS-i Master: Pressing the “set“ button of the AS-i Master shows the AS-i slave which was responsible for the last short-time configuration error. Was there a short-time AS-i power failure the display shows “39“ after pressing the “set“ button.

7.2 Error Counter: Counter of corrupted data telegrams

The AS-i Master with advanced diagnostics has an error counter for each AS-i slave, which is increased every time there is a corrupted AS-i telegram. This makes it possible to judge the quality of the AS-i network, even if only a few corrupted telegrams occurred and the AS-i slave did not cause any configuration errors.

The counter values can be read via the host interface and will be deleted with every read access. The counter value is limited to 254. 255 means counter overflow.

The error counter is included in the command Master | AS-i Diagnostics of AS-i Control Tools version 3.0.

7.3 Off-line Phase on Configuration Errors

The AS-i Masters with advanced diagnostics offer the possibility to put themselves into the Off-line Phase when a configuration error on the AS-Interface occurs. In this

way the security of the application can be ensured. The reaction to a configuration error is very fast and the host can be relieved from this task. If there are any problems on the AS-i network, the AS-interface can be switched to a secure state.

There are two different ways to parameterize the AS-i Master for this feature:

• Every configuration error during normal operation in protected mode releases the

Off-line Phase.

• For each slave address can be chosen whether a configuration error on this ad-

dress will release the Off-line Phase or not. This information is stored in the List of Off-line Slaves (LOS). The user himself can decide how the system reacts to a configuration error on the AS-interface. The AS-i Master can release the Off-line Phase in critical situations, i.e. only with certain slave addresses, while in less critical situations (if one of the other AS-i slaves have a configuration error) only the error message configuration error is sent to the host, but AS-i is still running.

The parameterization of Off-line Phase on Configuration Error is also supported by the AS-i Control Tools version 3.0.

AS-i/PROFIBUS Gateway

Profibus-DP

8 Profibus-DP

In this chapter, you learn everything necessary to run the AS-i/PROFIBUS Gateway in a Profibus-DP network.

For data exchange on Profibus-DP there are three operation modes: the easy mode, the advanced mode and the professional mode (advanced mode with management channel).

Hint: If you try to put an AS-i/PROFIBUS Gateway in operation the first time it is advisable to use the easy mode because it is much easier than the advanced modes.

The following table shows the differences between the three modes:

following Functions are available

Transmission of AS-i input and outut data

AS-Interface

Profibus-DP

8.1 Easy Mode

8.1.1 Mapping of the AS-i data in the Profibus-DP-Telegram

The inputs and outputs of the AS-i network are mapped identically in the DP master's input or output memory area respectively. In the easy mode the DP-telegram contains 16 bytes in- and output data with a single master.

AS-i circuit 1:

Byte 0 Byte 1 ... Byte 15

Slave 1, AS-i flags Slave 3, Slave 2 ... Slave 31, Slave 30

The AS-i flags and every AS-i slave take up four bits. The meaning and allocation of these bits is explained in the appendix, chapter 11.3.1.

If the AS-i flags shall not be used, you have to make sure that by all means these four bits are set to zero.

8.1.2 Configuration of the AS-i Network

The AS-i network can be put into operation without the Profibus-DP master. A connection to the Profibus-DP master is not necessary.

A comfortable way to configure the AS-i circuit on the AS-i/PROFIBUS Gateway is to use the Windows software AS-i Control Tools.

However it is also possible to configure the AS-i network locally on the gateway by using the push buttons “set“ and “mode“ (see chapter 6.4)

8.1.3 Projecting of the Profibus-DP Master

To project the Profibus-DP network you have to copy a GSD-file (enclosed on diskette) to the working directory of your Profibus configuration software (some programs have a directory named GSD, where the GSD-files have to be copied to, please see the manual of the used software). Depending on the software you may have to dispatch a command like „read GSD-files“.

The GSD-files can be found on the enclosed diskette „AS-i/PROFIBUS-Gateway IBM PC Software“ in the directory GSD.

For the easy mode the following GSD-files are available:

bwes1742.gsd

device: AS-i/PROFIBUS-DP Gateway, model name in the GSD-file: „AS-i/DP“

If the Profibus configuration software needs the older type files instead of the GSDfiles, please read the file \gsd\readme.txt on the enclosed diskette.

8.1.4 Parameterization of the Profibus-DP Slave

The parameters the gateway needs are completely appropriated by the GSD-file, there is no need to state user-parameters. If nevertheless user-parameters are transmitted, the device will switch to easy mode, if the first byte (element selection) is 00

AS-i/PROFIBUS Gateway

Profibus-DP

8.1.5 Configuration of the Profibus-DP Slave

In the easy mode the gateway uses a fixed I/O-configuration. If you use the GSD-file select the module “Standardmodus“.

If you configure the master without the GSD-file, select the identification byte 3F

(=63

hex

For double masters you need this identification byte for each AS-i circuit.

8.2 Advanced Mode

The extended functionality of the advanced mode affords a more extensive configuration of Profibus-DP. The I/O window can be adjusted optimally to the additional transmitted data (AS-i parameters, user memory, AS-i Control Code). The length of the I/O-window depends on the following factors:

• number of the AS-i slaves (number of input and output bytes)

• shall AS-i parameters be transmitted?

• shall AS-i Control code be transmitted?

• shall user memory be transmitted?

Size of the Window for the AS-i Input and Output Data

The size of the window for the AS-i input and output data is automatically adjusted to the AS-i configuration that is transmitted in the Profibus parameter telegram (user-parameter).

However, you must pay attention to this when configuring the Profibus-DP slave (see chapter 8.2.3).

Transmission of AS-i Parameters

For the transmission of AS-i parameters the DP-input and output data fields are enlarged by two bytes each. The AS-i slave address and the AS-i parameters are entered to these bytes. In the output data field, the DP master deposits the AS-i parameters to be written; in the input data field, the gateway deposits the data read during the AS-i parameterization.

The AS-i slaves are parameterized sequentially, i. e. only one slave can be parameterized in one Profibus cycle. The gateway signals errors of the parameterization by setting the leftmost bit in the slave address.

Transmission of AS-i Control code

dec

For AS-i/PROFIBUS Gateways with 2 AS-i Masters and/or the advanced AS-i diagnostics1 we recommend to use the professional mode instead of the older advanced mode.

1. these are all devices that were delivered since September 1998; these devices have the following feature string:

„*B..Dc..***.....“ oder „*B..Dc2.***.....“, * is a placeholder for various characters

(this string can be read with AS-i Control Tools with the command Master | Identity)

AS-Interface

Profibus-DP

For the programming of AS-i Control, the I/O field is further enlarged by 5-17 additional bytes. They contain an identification byte (read/write/start/stop), the base address and 2-14 bytes user data. It is not possible to read and write at the same time.

Transmission of user memory

User memory can be transmitted in the I/O field by adding bytes for the memory locations to be written (O-field) or to be read (I-field). The amount of user memory to be written or read can be different.

8.2.1 Mapping of the AS-i Data in the Profibus-DP Telegram

The data in the DP telegram is always mapped in the same fixed order:

• AS-i I/O data

• AS-i parameters

• AS-i Control code

• user memory If some elements are missing (e.g. no transfer of the AS-i Control code), subsequent

elements are added directly.

The individual parts of the DP-telegram are coded as follows:

N bytes AS-i I/O data

2 bytes AS-i parameter

5-17 bytes AS-i Control

M bytes user memory

code

user memory 0.. user memory M-1

high address, control byte low-address, L bytes data

AS-i slave address, AS-i parameter

byte 0. .. byte N-1

slave 1 AS-i flags ... slave (K-1) slave (K-2)

with K = number of AS-i slaves + 1

(instead of slave 0 the AS-i flags are transmitted) N = K/2 M = number of user memory bytes up to 128 bytes L = number of bytes of AS-i Control code

(calculated out of value in element selection of the user-parameter telegram)

AS-i/PROFIBUS Gateway

Profibus-DP

The AS-i flags and every AS-i slave take up four bits. The meaning and allocation of these bits is explained in the appendix, chapter 11.3.2.

If the AS-i flags shall not be used, you have to make sure that by all means these four bits are set to zero.

Bit allocation AS-i parameters: see appendix, chapter 11.3.2. Constants for the control byte in the DP-telegram's AS-i Control part: see appendix,

see chapter 11.3.3.

8.2.2 Configuration of the AS-i Network

During the building up of the connection to a Profibus-DP master, the AS-i network is configured via the Profibus. The AS-i configuration does not have to be stored locally (via the push buttons mode and set or the AS-i Control Tools). Merely the AS-i slaves have to get the designated addresses.

The AS-i/PROFIBUS Gateway compares the nominated AS-i configuration received from the DP-master with the actual configuration of the AS-i network. If they match, the gateway does data exchange on AS-i. (This does not affect the data exchange on Profibus).

The AS-i configuration data of the AS-i slaves (ID-code and I/O-configuration) should be known before configuring the DP-master. You find them in the AS-i slave's documentation.

The configuration via Profibus-DP offers the following advantage: The AS-i configuration data of the AS-i network is stored in the DP-master. This way, an immediate start-up without any need for manual intervention is possible when exchanging the gateway (one exception is the Profibus station address).

8.2.3 Configuration of the Profibus-DP Master

The GSD-files can be found on the enclosed diskette „AS-i/PROFIBUS-Gateway IBM PC Software“ in the directory \GSD.

For the advanced mode the following GSD-files are available:

bwas1742.gsd

device: AS-i/PROFIBUS-DP Gateway, model name in the GSD-file: „AS-i/DP-A“

If the Profibus configuration software needs the older type files instead of the GSDfiles, please read the file \gsd\readme.txt on the enclosed diskette.

Profibus-DP

Only "standard identification bytes" with a maximum size of 16 bytes or words may be used as identification bytes. If the data windows to be transmitted shall be bigger than 16 bytes or words, they have to be out together out of several "standard identification bytes".

If the requested data field length is smaller than the one calculated out of the parameter telegram, the gateway will not take up any communication relationship with the DP-master.

The maximum data field length for input respectively output data is 149 bytes with a device with one AS-i Master and 160 bytes with a device with two AS-i Masters.

8.3 Professional Mode

All AS-i/PROFIBUS Gateways with 2 AS-i Masters and/or the advanced AS-i diagnostics1 have a third operation mode, which we call the professional mode. We recommend the use of the professional mode instead of the older advanced mode.

The AS-i/PROFIBUS Gateways with 2 AS-i Masters only allow the use of the easy mode or the professional mode. The AS-i/PROFIBUS Gateways (FMS/DP) only run in the easy mode or the advanced mode.

The extended functionality of the advanced mode affords a more extensive configuration of Profibus-DP. The I/O-window has to be enlarged for the additional data (management commands and user memory). The length of the I/O-window depends on the following factors:

• number of the AS-i slaves (number of input and output bytes)

• size of the management channel (0, 3 or 5 Bytes)

• number of the user memory bytes

Size of the Window for the AS-i Input and Output Data

The size of the window for the AS-i input and output data has to be adjusted to the AS-i configuration (see chapter 8.3.3).

Transmission of Management Commands (0, 3 or 5 bytes)

With the management commands you can transmit acyclically additional AS-i data like e.g. AS-i parameters or reading the LDS or also writing the AS-i Control flags e.g. to start an AS-i Control program.

The management channel uses either 3 or 5 bytes. If the commands write LPS, read LPS, read LAS, read LDS, read LCS, read communication errors, write LOS or read LOS shall be used, the management channel has to have a length of 5 bytes because these commands use 4 bytes of data.

The management channel is built up as follows:

byte 0 byte 1 - 2 respectively 1 - 4 Profibus output data command byte output data Profibus input data mirrored command byte input data

If the same command byte shall be sent several times one after the other, the bit 7 (valence 27) has to be toggled each repetition.

The bit 6 (valence 26) of the command byte states the number of the AS-i Masters to address to. If this bit is 0, AS-i Master 1 is addressed, otherwise AS-i Master 2. With single masters this bit has to be 0, with double masters the AS-i circuit to address can be selected. (e.g. command read AS-i Control Flags of AS-i circuit 2: 4D

After execution of the command the command byte is mirrored. Illegal commands (AS-i circuit number 2 with single masters, illegal command byte or a data field which is too short) always return as mirrored command byte 00 was set.

• AS-i command call : The function of the execution control Execute_Command() is executed. The in-

formation part of the master request has to be stated in “data“. (see AS-i specification).

The AS-i Master stores the slave answer in the byte “answer“.

• LPS, LAS, LDS, LCS, LOS: Structure of the AS-i slave lists see appendix, chapter 11.1.

• read communication errors: For each slave there is one byte for the number of communication errors that

occurred since the last read access. With every read access only 4 bytes are read simultaneously. Therefore you have to state the index for the data you want to read:

index = slave address / 4 (integer) data byte number = slave address - (4 * index)

Transmission of user memory

The user memory is transmitted in an own Profibus slot. The amount of user memory to be written or read can be different.

• AS-i parameters

• AS-i Control code

• user memory

If some elements are missing (e.g. no transfer of the AS-i Control code), subsequent elements are added directly.

The AS-i data is represented in the DP-telegram as follows:

byte 0 byte 1 ... byte N-1

slave 1, AS-i flags slave 2, slave 3 ... slave(K-1), slave(K-2)

with K = number of AS-i slaves + 1

(instead of slave 0 the AS-i flags are transmitted) N = K/2

Profibus-DP

The AS-i flags and every AS-i slave take up four bits. The meaning and allocation of these bits is explained in the appendix, chapter 11.3.1.

If the AS-i flags shall not be used, you have to make sure that by all means these four bits are set to zero.

8.3.2 Configuration of the AS-i Network

During the building up of the connection to a Profibus-DP master, the AS-i network is configured via the Profibus, unless the AS-i configuration and the AS-i (startup) parameters are not stated in the Profibus parameter telegram. The AS-i configuration only has to be stored locally (via the push buttons mode and set or the AS-i Control Tools), if the configuration of AS-i was not stated in the Profibus parameter telegram. Merely the AS-i slaves have to get the designated addresses.

The AS-i configuration data of the AS-i slaves (ID-code and I/O-configuration) should be known before configuring the DP-master. You find them in the AS-i slave's documentation.

If the AS-i configuration and the AS-i (startup) parameters were not stated in the Profibus parameter telegram AS-i has to be projected (and the configuration stored) with the push buttons at the device or with the windows software AS-i Control Tools.

8.3.3 Configuration of the Profibus-DP Master

The GSD-files can be found on the enclosed diskette „AS-i/PROFIBUS-Gateway IBM PC Software“ in the directory \GSD.

For the professional mode the following GSD-files are available:

AS-i/PROFIBUS Gateway

Profibus-DP

Parameterization of the Profibus-DP-Slave

The parameters needed by the gateway are coded in the user-parameters. They contain one byte to select the professional mode, the AS-i configuration data and AS-i parameters for all the AS-i slaves and the statements about user memory bytes to be read and to be written.

user memory

hex

statement (4bytes)

The fields user memory statement and AS-i configuration data and AS-i (startup-) parameters are optional. However the order of the fields is stipulated. Therefore the following four combinations are possible:

hex

user memory

hex

statement (4bytes)

AS-i configuration data and AS-i (startup-) parameters of AS-icircuit1 (62 bytes)

AS-i configuration data and AS-i (startup-) parameters of AS-icircuit2 (62bytes)

user memory

hex

statement (4bytes)

AS-i configuration data and AS-i (startup-) parameters of AS-icircuit1 (62 bytes)

hex

statement (4bytes)

AS-i configuration data and AS-i (startup-) parameters of AS-icircuit1 (62 bytes)

AS-i configuration data and AS-i (startup-) parameters of AS-icircuit2 (62bytes)

In the cases 1 and 2 no AS-i configuration data and AS-i (startup-) parameters are stated in the user parameter telegram. In these cases the AS-i configurations stored in the EEPROM of the AS-i/PROFIBUS Gateway are used. So AS-i can be projected using the AS-i Control Tools or the push buttons on the device before Profibus is put into operation.

The fields of the Profibus parameter telegram are constructed as follows:

• user memory statement (4 bytes) Byte 0: Start address of the user memory window in the input data telegram

(read user memory)

Byte 1: Length of the user memory window in the input data telegram

AS-i/PROFIBUS Gateway

Profibus-DP

(all data stated in hexadecimal code)

Profibus Configuration of the Profibus-DP slave

The Profibus configuration of the AS-i/PROFIBUS Gateways built up out of the following Profibus slots:

process data/AS-i flags of AS-i Master 1

standard identification byte (1..16 bytes) or empty slot

management channel

standard identification byte 0xB2 (3 bytes) or 0xB4 (5 bytes) or empty slot

user memory (AS-i Control)

standard identification byte or extended identification byte (altogether up to 128 bytes) or empty slot

Empty slots at the end of the configuration telegram can be left out. In contrast to the easy mode, the size of the I/O window can be matched to the exten-

sion of the AS-i network. Its size in bytes amounts:

(highest AS-i slave address + 1) / 2 Any non-integer value has to be rounded up to a full byte. If the requested data field length for the user memory is smaller than the calculated

length from the parameter telegram, the gateway will not take up any communication relationship with the DP-master.

The maximum data field length for input respectively output data is 149 bytes with a device with one AS-i Master.

8.4 Profibus Diagnosis telegram

Besides the on-the-spot-diagnosis via the figure display and the seven LEDs, there is also the possibility of a diagnosis via the Profibus-DP. The Profibus diagnosis telegram meets the Profibus norm.

The Profibus diagnosis telegram depends on the operation mode.

8.4.1 Diagnosis telegram in easy mode and advanced mode

The diagnosis telegram contains 9 bytes in the easy mode or the advanced mode. The structure is represented in the following table.

byte content

9 Accessories for Putting AS-i into Operation and Test Tools

The AS-i circuit on the AS-i/Profibus Gateway can be put into operation with the comfortable Windows software AS-i Control Tools. This software communicates with the AS-i/Profibus Gateway by means of the Profibus converter, which converts the RS232-signals of the PC to Profibus.

The Profibus DP Master Simulator is recommended for testing the gateway. With the Profibus DP Master Simulator the AS-i/Profibus Gateway can be put into operation with or without GSD-file. The user parameter string that is needed for advanced mode or professional mode can be edited and tested. The Profibus DP Master Simulator can also be used as a Profibus converter. Furthermore the Profibus DP Master Simulator can be used for putting any Profibus-DP slave into operation which is very useful for diagnostic purposes.

9.1 Windows Software AS-i Control Tools

The Windows software AS-i Control Tools enables you to configure the AS-i circuit in a very comfortable manner.

1. For that purpose plug in a Bihl+Wiedemann Profibus converter to the D-SUB-connector of the AS-i/PROFIBUS Gateway and connect the device with a fully covered cable to the serial interface of your PC.

2. Start the AS-i Control Tools.

3. Call the command Master | New.

4. Choose Profibus as protocol.

7. Click on a slave entry to open the dialogbox slave configuration.

This dialog box is for changing a slave address, setting AS-i parameters or AS-i configuration data. Additionally you can test inputs and outputs.

A very easy approach to configure the AS-i circuit is connecting each AS-i slave to the line and setting the AS-i slave address one after the other. After that press the button “Store configuration“ to adopt the detected AS-i circuit to the AS-i Master as projected data.

Moreover you can use the AS-i Address Assistant. This tool changes automatically the address of an AS-i slave to the desired address after plugging the slave to the AS-i line. The desired AS-i configuration can be created off-line before and stored to a file. When you build up the plant you only have to plug the AS-i slaves to the AS-i line one after the other.

Further descriptions to all features of the software can be obtained from the integrated help.

9.2 Profibus-DP-Mastersimulator

The Profibus DP Mastersimulator is a simple universal tool for data exchange with Profibus slaves of almost all manufacturers via Profibus DP. The Profibus DP Mastersimulator can exchange data with a Profibus slave even without GSD file, without type file and without a Profibus master. Without further inputs or additional files the Profibus Slave can be put into operation with the default I/O width. Input data can be read and output data be written. This is particularly important with time-critical troubleshoot at the Profibus, if e.g. diskettes of several manufacturers are not seizable. Beyond that the Profibus DP Mastersimulator enables also the use of GSD files, of course, as well as the input of special configurations for starting data exchange with Profibus slaves. Addressing of Profibus Slaves - above all the IP67-Module without address switches - is likewise possible. In the scope of supply of the Profibus DP

The scope of supply of the Profibus DP Mastersimulator contains a simple Profibus converter. The Profibus converter is the ideal interface converter between the RS232 interface of the PC and the Profibus. The converter is very compact and needs no additional external power supply. Therefore it is in the best way suitable also for mobile build-up with a laptop or a notebook. The Profibus converter can simply be connected between the Profibus slave and the RS232 interface cable.

10 Displays of the Figure Display

In the basic state of the configuration mode, the display shows one after the other the addresses of all detected slaves at a rate of two per second. A blank display means that the LDS is empty, i.e. no slaves were detected.

In the basic state of the protected operating mode, the display is either blank or displays the address of a faulty assignment (see chapter 6.3.2).

During manual address programming, the slave address display has a different meaning, of course (see chapter 6.4 and 6.5).

All displayed numbers that are bigger than 31 and therefore can not be interpreted as a slave address are status or error messages of the master. They have the following meanings:

40 The AS-i master is in off-line phase. 41 The AS-i master is in detection phase. 42 The AS-i master is in activation phase. 43 The AS-i master starts normal operating mode. 70 Hardware error: The AS-i master’s EEPROM cannot be written to. 72 Hardware error: The PIC processor does not respond. 73 Hardware error: The PIC processor does not respond. 74 Checksum error in the EEPROM. 75 Error in the external RAM. 76 Error in the external RAM. 80 Error while attempting to exit the configuration mode: A slave with address

AS-i/PROFIBUS Gateway

Appendix: The First Commissioning of AS-i

12 Appendix: The First Commissioning of AS-i

In this chapter an example is given of how to put an AS-i network into operation quickly and easily and without the need for external devices. The addressing of the components connected to the AS i network can be performed directly on the AS i master. It is of course more comfortable to do the addressing with a hand-held programming device or a PC. However, it is possible to configure even complex networks using only the AS i master.

What to do ? How to go about it?

See to it that the AS-i master is properly supplied with power.

After the self-test: the LEDs "power", "config err", "U ASI" and "prj mode" are on. The LCD shows "40": the AS-i master is in the off-line phase. Shortly after that a "41" will be displayed: the AS-i master stays in the detection phase.

Switch the device to the projecting mode, if the yellow LED does not light up.

The yellow LED "prj mode" lights up. The device is now in projecting mode. Add a slave with the address 0 to the

AS-i line. The green LED "ASI active" lights up. The LCD shows "0". This means the AS-i

master has detected the slave. Change the slave address to address 1. Select address 1 by pressing the "set"

The AS-i master detects the slave with address 1 and displays "1". Connect another slave with address 0 to

the AS-i line and allocate the address 2 to it.

The addresses of all slaves detected are now displayed sequentially.

Using AS-i master with power supply "A": connect the AS-i power supply unit to the terminals AS-i + and AS-i - of the master, connect the ground terminal. Using AS-i master with power supply "N": connect the 24 V DC standard power supply with the terminals 24V and 0V of the master, connect the ground terminal. Turn on the power supply.

Press the "mode"-button for approx. five seconds.

Connect the slave's terminals with the terminals AS-i + / - of the master.

button shortly, if necessary repeatedly. When a ”1” appears on the display press the ”set” button for approx. five seconds until the display blinks. Press again shortly the ”set” button to assign the new address to the slave.

Connect the slave to the AS-i line. The addressing is the same as for the previous slave.

Appendix: The First Commissioning of AS-i

What to do ? How to go about it?

Change to the protected operating mode and store the AS-i configuration.

The configuration of the master is now finished. If the AS-i Master is a gateway, the hierarchically higher fieldbus system can be put into operation now.

The gateway stays in the off-line phase (the display shows "40"), the LED "config err" lights up), until the hierarchically higher fieldbus system operates properly.

Leave the configuration mode by pressing the "mode" button for at least five seconds until the "prj mode" LED goes out.
