3.3.1 Connecting the Leuze device

 To connect the Leuze device to the internal RS 232 device interface, open the housing

of the MA 204 for BCL 32) through the middle threaded opening.

 Connect the cable to the internal device interface (X30, X31 or X32, see chapter 7.5.1).

 Use rotary switch S4 (see chapter 8.2.5) to select the connected device.

 Now screw the PG cable gland into the threaded opening to provide strain relief and

ensure protection class IP 65.

3.3.2 Setting the PROFIBUS device address

 Set the station address of the gateway via the rotary switch S1 - S3 (ones, tens and

hundreds digits).

Notice!

The PROFIBUS permits an address range from 0 to 126. Address 126 must not be used for data communication. It may only be used temporarily for commissioning. Make certain that you assign each PROFIBUS participant a different PROFIBUS address.

i and guide the corresponding device cable (see chapter 14.7, e.g., KB 031

Figure 3.2: Rotary switch for setting the address

 Finally, close the housing of the MA 204

Attention!

Only then may the supply voltage be applied. Upon startup of the MA 204i, the device selection switch and the address settings are queried and the gateway automatically sets itself to the Leuze device.

Connecting functional earth FE

 Ensure that the functional earth (FE) is connected correctly.

12 MA 204i Leuze electronic

Fast commissioning / operating principle

Unimpaired operation is only guaranteed when the functional earth is connected properly. All electrical disturbances (EMC couplings) are discharged via the functional earth connection.

3.3.3 Connecting the power supply and the bus cable

 Ideally, use the ready-made cables listed in chapter 14.5.3 to connect the gateway to the

power supply via the PWR IN connection.

 For the connection of the gateway to the fieldbus via the HOST / BUS IN connection,

the ready-made cables listed in are preferred.

 If applicable, use the BUS OUT connection if you would like to construct a network with

linear topology.

3.4 Starting the device

 Apply the supply voltage +18 … 30 V DC (+24 V DC model).

The MA 204

i starts up; the PWR LED displays that it is ready for operation.

3.5 Commissioning the MA 204

 Complete the necessary steps for commissioning a Siemens-S7 control as described

below.

Further information regarding the individual commissioning steps is provided in see chapter

12.3 "Configuration steps for a Siemens Simatic S7 control".

3.5.1 Preparing the control system

 In the first step, prepare the control for consistent data transmission.

During programming the control system must be prepared for consistent data transmission. This varies from control system to control system. The following possibilities are available for the Siemens control systems.

The specific function blocks SFC 14 for input data and SFC 15 for output data must be integrated in the program. These are standard function blocks and are used to facilitate consistent data transmission.

Notice!

If an S7 control is used, you need to ensure that Simatic-Manager Version 5.4 + service pack 5 (V5.4+SP5) or higher is used.

3.5.2 Installation of the GSD file

For the subsequent configuration of the PROFIBUS devices, e.g., MA 204 corresponding GSD file must be loaded first. All data in modules required for operating the device is described in this file. These are input and output data and device parameters for the functioning of the device and the definition of the control and status bits.

 Install the GSD file associated with the device in the PROFIBUS Manager of your control.

3.5.3 Configuration

 Configure the PROFIBUS system using the HW Config of the SIMATIC Manager by

inserting the MA 204

Figure 3.3: Assignment of the device address

14 MA 204i Leuze electronic

Fast commissioning / operating principle

3.5.4 Configuration of the modules

 Now select a corresponding data module for the input and output area.

A number of combinable modules are available with various data lengths (4, 8, 12, 16, 20, 32 … 128 bytes). In total, a maximum of 244 bytes are possible for both the input bytes and for the output bytes.

Notice!

Because the data module contains 2 bytes for the control and status bytes, the actual user data length is always 2 bytes smaller than the selected data module. E.g., when using the data module with 12 bytes, there are effectively 10 bytes available for user data on the Leuze device after subtracting the 2 bytes for status and control bytes.

Recommendation

In most cases, the 4-byte module is sufficient for the output module.

A larger module is needed, for example, if a BCL bar code scanner is to be configured by means of PT-sequences, or an RFID transponder is to be described. In these cases, larger data modules are usually sensible.

Notice!

Examples for selecting the correct data module length can be found in chapter 12.3.4, section "Examples of sensible settings for corresponding Leuze devices" on page 63.

3.5.5 Transmission of the configuration to the controller

 Transmit PROFIBUS configuration to the controller (S7 PLC).

After correct transmission to the controller (S7 PLC), the PLC automatically carries out the following activities:

• Establishment of a connection between the controller and configured PROFIBUS devices

• Cyclical data exchange

Various device versions are available for the conventional fieldbuses. With a stored parameter structure for the connectable RS 232 devices, commissioning could hardly be simpler.

i gateways are intended for use in industrial environments

4.2 Characteristics of the connector units

A special characteristic of the MA 204

1. Transparent mode In this function mode, the MA 204 communication from and to the PLC. Absolutely no special programming by the user is necessary for this purpose. The data is not buffered or stored temporarily, however. Instead, it is "passed on".

The programmer must make certain to retrieve the data from the input memory of the PLC at the right time, as it is otherwise overwritten by new data.

2. Collective mode In this operating mode, data and telegram parts are temporarily stored in the memory (buffer) of the MA and sent to the RS 232 interface or to the PLC in a telegram by means of bit activation. In this mode, however, all communication control must be programmed on the PLC.

This function mode is helpful, for example, for very long telegrams or when one or more codes with long code lengths are read.

i family is a versatile gateway for integrating Leuze

i device family are three function modes:

i functions as a pure gateway with automatic

3. Command mode

With this special operating mode, it is possible to use the first bytes of the data range

to transmit predefined commands to the connected device by means of bit activation. For this purpose, device-dependent commands (so-called online commands) are predefined via the device selection switch, see chapter 16 "Specifications for Leuze end devices".

If the actual data length is longer than the data length configured in the gateway, only part of the data is transmitted; the remaining data is lost. In this case, the DL (data loss) bit is set.

The following telegram structure is used between PLC -> fieldbus gateway:

7 6 5 4 3 2 1 0

ND Address 4 Address 3 Address 2 Address 1 Address 0 Broadcast Command

CTB SFB R-ACK Control byte 1

Data

Only the data part with the corresponding frame (e.g., STX, CR & LF) is then transmitted between the fieldbus gateway and the Leuze end device. The two control bytes are processed by the fieldbus gateway.

The corresponding control and status bits and their meaning are specified in section 10.2 and section 10.3.

Further information on the broadcast control bytes and address bits 0 … 4 can be found in chapter "Modular interfacing unit MA 3x (S4 switch position C)" on page 95.

10.2.2 Detailed description of the bits (input byte 0)

Bit 0: Write-Acknowledge: W-ACK

This bit is only relevant for writing slave data in blocks, see chapter (buffer data on RS 232). It toggles when data from the PLC are sent to the MA with CTB or SFB.

Input data Description Addr. Data

Write-Acknowledge

(write confirmation) Write handshake Indicates that the data was successfully sent by the PLC to

W-ACK

the gateway. Write-Acknowledge is indicated via this bit. The W-ACK bit is toggled by the fieldbus gateway whenever a transmit command has been successfully executed. This applies both for the transmission of data to the transmit buffer with the CTB command and for sending the transmit buffer contents with the SFB command.

Copy to transmit buffer

(transmission data to transmit buffer) Toggle bit: Changing this bit writes the data from the PLC to

CTB

the transmit buffer of the fieldbus gateway. This is used, for example, for long command strings which must be transmitted to the connected ident device. The CTB toggle bit is switched whenever transmit data is not to be sent directly via the serial interface, but instead transferred to the transmit buffer.

Notice!

The state change of the CTB bit signals the MA that the data is going into the buffer; therefore, it's essential to observe the order! When the CTB is not used, the telegram (which fits in one cycle) is transmitted directly to the RS 232 interface. Please make sure it is complete!

10.4 Delete RESET function / memory

For many applications, it is helpful to be able to reset the MA buffer (in Collective mode) or status bits.

The following bit pattern can be transmitted from the PLC for this purpose (if >20 ms is pending):

Control byte 0: 10101010 (AAh) Control byte 1: 10101010 (AAh) OUT data byte 0/parameter byte 0: AAh OUT data byte 1/parameter byte 1: AAh

Modes

11 Modes

11.1 Functionality of the data exchange

The fieldbus gateway has two different modes that can be selected via the PLC:

• Transparent mode (default setting) In Transparent mode, all data are sent 1:1 and directly by the serial end device to the PLC. It is not necessary to use status and control bits here. However, only data bytes possible for one transmission cycle are transmitted - all others are lost. The distance between two successive telegrams (without frame) must be more than 20 ms, since there is otherwise no clear separation between them. ASCII characters are typically expected as data content; under certain circumstances, the MA therefore detects different control characters as invalid characters in the data range and truncates them. At 00 because unnecessary bytes are also filled with 00h .

• Collective mode In Collective mode, the data of the serial end device is stored temporarily in the fieldbus gateway by toggling the CTB bit and is not sent to the PLC in blocks until prompted to do so by the PLC. On the PLC, a status bit (DEX) then signals that new data is ready for retrieval. This data is then read out from the fieldbus gateway in blocks (toggle bit). In order to distinguish between the individual telegrams on the PLC, in Collective mode the serial frame is sent to the PLC in addition to the data.

The size of the buffer is 1 kByte.

in the data range, the MA cuts the telegram off

Notice!

In Collective mode, the CTB and SFB bits are needed for communication handling via the buffer. Telegrams that can also be completely transmitted in one cycle in Collective mode (including data frame) go directly through. If PLC data is provided and transferred without a state change of the CTB bit, it goes directly to the RS 232 interface with the set telegram data length. Incomplete (incl. data frame) or faulty telegrams can cause error messages in the connected device!

Combination with the Command mode is possible.

Data exchange in blocks must be programmed on the PLC.

11.1.1 Reading slave data in Collective mode (gateway -> PLC)

If the Leuze device transmits data to the fieldbus gateway, the data is stored temporarily in a buffer. The PLC is signaled via the "DEX" bit that data is ready for retrieval in the memory. Data is not automatically transmitted.

If no further user data is present in the MA 2xx toggled once as read confirmation to release data transmission for the next read cycle.

52 MA 204i Leuze electronic

i ("DEX" bit = "0"), the "R-ACK" bit must be

Modes

If the buffer still contains more data ("DEX bit = 1), the next remaining user data present in the buffer is transmitted by toggling the "R-ACK" control bit. This process is to be repeated until the "DEX" bit returns to "0"; all data has then been removed from the buffer. "R-ACK" must be toggled here again once more as a terminating read confirmation in order to release data transmission for the next read cycle.

Used status and control bits:

•DLC

•BLR

•DEX

•R-ACK

Writing slave data in Collective mode (PLC -> gateway)Writing in blocks

The data sent by the master to the slave is first collected in a "transmit buffer" by setting the "CTB" bit (Copy to transmit buffer). Please observe that data provided is transmitted directly by toggling the bit.

The data is then sent in the order received from the buffer to the connected Leuze device via the serial interface with the command: "SFB" (Send data from transmit buffer). Please don't forget the suitable data frame!

Afterward, the buffer is again empty and can be written with new data.

Notice!

With this function, it is possible to temporarily store longer data strings in the gateway independent of how many bytes the used fieldbus can transmit at once. With this function, longer PT sequences or RFID write sequences, for example, can be transmitted, since the connected devices can, in this way, receive their commands (e.g., PT or W) in a continuous string. The respective frame (STX CR LF) is needed to differentiate between the individual telegrams.

Used status and control bits:

•CTB

•SFB

TNT 35/7-24V

11.1.2 W-ACK

If PLC data is provided and transferred without a state change of the CTB bit, it goes directly to the RS 232 interface with the set telegram data length. Incomplete (incl. data frame) or faulty telegrams can cause error messages in the connected device!

Examples for the activation of a Leuze device

In the data part (starting at byte 2) of the telegram to the gateway, a "+" (ASCII) is sent for activation.

Modes

11.1.3 Command mode

One specific feature is the so-called Command mode, which is defined via the output control byte 0 (bit 0)... and enables the control of the connected device per bit.

If the Command mode is activated (Command mode = 1), no data is sent by the PLC to the Leuze end device via the gateway. The data from the MA to the PLC is transmitted in the selected operating mode (Transparent/Collective).

With the Command mode, it is possible to set various device-specific bits in the data- or parameter field that execute the corresponding serial commands (e.g., v, +, -, etc.). If, for example, the version of the Leuze end device is to be queried, the corresponding bit is to be set so that a "v" is sent to the Leuze device with the <STX> v <CR> <LF> frame.

The Leuze end device also answers the gateway with data (e.g. bar code content, NoRead, device version, etc.) in response to most commands. The answer is immediately passed on to the PLC by the gateway.

Notice!

The parameters available for the individual Leuze devices are listed in chapter 16. Command mode cannot be used with hand-held scanners.

In most cases, the 4-byte module is sufficient for the output module. A larger module is needed, for example, if a BCL bar code scanner is to be configured by means of PT-sequences, or an RFID transponder is to be described. In these cases, larger data modules are usually sensible.

Examples of sensible settings for corresponding Leuze devices

BPS 8

• Input module: 8 bytes

• Output module: 4 bytes

AMS

• Input module: 8 bytes

• Output module: 8 bytes

Hand-held scanner

• Input module: individual

The size of the input module is dependent on the number of digits of the bar code or 2D code that is to be read. For example, with an 12-digit bar code (+ 2 bytes of status bytes), the input module with 16 bytes is sensible.

• Output module: none

Because the hand-held scanner does not typically send any data, no output module is necessary.

BCL bar code scanners, RFID devices (RFM, RFI and RFU), LSIS 122 and LSIS 4x2i

• Input module: individual

The size of the input module is dependent on the number of digits of the bar code, RFID code or 2D code that is to be read. For example, with an 18-digit bar code (+ 2 bytes of status bytes), the input module with 20 bytes is sensible.

• Output module: 4 bytes

12.3.5 Step 5 – Transmission of the configuration to the controller (S7 PLC)

After correct transmission to the controller (S7 PLC), the PLC automatically carries out the following activities:

• Check device names

• Establishment of a connection between the controller and configured PROFIBUS devices

• Cyclical data exchange

12.5 General information on the PROFIBUS implementation of the MA 204

12.5.1 Communication profile

The communication profile defines how participants serially transmit their data via the transmission medium. The MA 204 systems and Decentral Periphery -> PROFIBUS DP.

DP communication profile

The PROFIBUS DP communication profile is designed for efficient data exchange on the field level. Data exchange with the decentral devices occurs primarily cyclically. The necessary communication functions are defined in the DP base functions. The DP optionally offers acyclic communication services as well. These are used for configuring, operating, observing and alarm handling.

In order to be able to perform data exchange, services are defined which PROFIBUS DP differentiates between on the basis of the data access points transmitted in the telegram header.

The MA 204

i supports the communication profile for automation

i profile is based on the PROFIBUS profile for identification systems.

12.5.2 Bus-access protocol

The PROFIBUS communication profiles (DP,FMS) use a uniform bus-access process. It is implemented by layer 2 of the OSI model. The bus-access control (MAC) defines the process for specifying the point in time at which a network device can transmit data. It must ensure that no more than one participant has permission to transmit at any given time. The PROFIBUS bus-access process includes the token-passing process and the master-slave process.

Process Description MA 204i

Token-passing process

Master-slave process

Table 12.1: PROFIBUS bus-access processes

The two processes can also be mixed in order to create a multi-master system. The MA 204i functions both in a mono-master system as well as in a multi-master system.

Notice!

In 2007, the PROFIBUS DP was extended by the DPV2 specification. The specification will then also permit slave-slave communication. The MA 204 communication.

12.5.3 Device types

With the PROFIBUS DP, there are two types of master and one type of slave:

Commissioning and configuration

With this process, the bus-access permission is distributed by means of a token. The participant obtains permission to transmit with t he token. The token wanders between the master devices in the ring in a permanently defined time frame. This type of bus access is used for communication between the masters. Various slave devices are assigned to a master. The master can address the slaves which are assigned to it and fetch messages from them. The master always has the initiative.

12.5.5 Modular structure of the parameter

The PROFIBUS DP functionality of the device is defined via parameter sets which are clustered in modules. The modules are included in a GSD file, which is supplied as an integral part of the device. By using a user-specific project tool, such as, e.g., Simatic Manager for the Siemens programmable logic control, the required modules are integrated into a project during commissioning and its settings and parameters are adjusted accordingly. These modules are provided by the GSD file.

Notice!

All input and output modules described in this documentation are described from the controller's perspective:

- Input data arrives at the controller.

- Output data is sent out by the controller.

Detailed information on how to prepare the control and the GSD file may be found in chapter "Configuration steps for a Siemens Simatic S7 control" on page 60.

For the default settings of the MA 204

Notice!

Please note that the set data is overwritten by the PLC! Some controls make available a so-called "universal module". This module must not be activated for the MA 204

i, please refer to the following module descriptions.

From the perspective of the device, a distinction is made between PROFIBUS parameters and internal parameters. PROFIBUS parameters are all parameters that can be changed via the PROFIBUS and are described in the following modules. Internal parameters, on the other hand, can only be changed via a service interface and retain their value even following a PROFIBUS configuration.

During the configuration phase, the MA 204 IO Controller (master). Before this is evaluated and the respective parameter values are set, all PROFIBUS parameters are reset to default values. This ensures that the parameters of modules that are not selected are set to the default values.

12.5.6 Permanently defined parameters/device parameters

On the PROFIBUS, parameters may be stored in modules or may be defined permanently in a PROFIBUS participant.

The permanently defined parameters are called "common" parameters or device-specific parameters, depending on the configuration tool.

These parameters must always be present. They are defined outside of the configuration modules and are permanently anchored in the telegram header.

In Simatic Manager, the permanently defined parameters are set via object properties of the device. The module parameters are set via the module list of the selected device. By selecting the project properties of a module, the respective parameters may be set if required.

The following list contains the device parameters that are permanently defined in the MA 204

12.5.7 Overview of the project modules

When using PROFIBUS modules, the parameters are assembled dynamically, i.e., only the parameters that were selected by the activated modules are changed.

The MA 204 parameters are defined outside of modules and are thus linked to the base module (DAP).

In the current version, several modules are available for use. A device module (DAP, see Permanently defined parameters/device parameters) is used for basic scanner configuration of the MA 204 included into the project according to requirements and application.

The modules fall into the following categories:

• Parameter module for the configuration of the MA 204

• Status or control modules that influence the input/output data.

• Modules that may include both parameters and control or status information.

A PROFIBUS module defines the existence and meaning of the input and output data. In addition, it defines the necessary parameters. The arrangement of the data within a module is defined.

The composition of the input/output data is defined via the module list.

The MA 204 the MA 204 during initialization.

The same applies for the input data. Using the module list and the defined module properties, the input data string is formatted and referenced to the internal data.

During cyclic operation, the input data is then passed on to the controller.

During the startup or initialization phase, the MA 204 (usually 0).

i has parameters (device parameters) that must always be present. These

Each of these modules may only be selected once; otherwise, the MA 204 The MA 204i checks its max. permissible number of modules. The control also reports an error if the input and output data across all selected modules exceed a total length of 488 bytes. A maximum of 244 bytes can be used for both the input data and for the output data. The specific limits of the individual modules of the MA 204i are declared in the GSD file.

Notice!

If an S7 control is used, you need to ensure that Simatic-Manager Version 5.4 + service pack 5 (V5.4+SP5) or higher is used.

12.6 Variable configuration of the communication data width

The communication of the MA 204 able data width; the upper limit is restricted by the fieldbus. The following sizes are available for the data frame for PROFIBUS DP:

4, 8, 12, 16, 20, 24, 28, 36, 64, 128 bytes

The small data lengths (< 28 bytes) are particularly of interest for use with bar code scanners (BCL). The larger data lengths are, on the other hand, relevant for 2D code scanners (handheld scanners, LSIS) and RFID.

Taking into consideration the maximum permissible data width of 244 bytes, multiple modules can also be used for the input data or combined with one another. The combination of module 128 and module 64, for example, yields an input data length of 192 bytes.

16 Specifications for Leuze end devices

Serial interface and Command mode

The corresponding Leuze end device can be selected while configuring the fieldbus gateway (see chapter 9 "Configuration").

The exact specifications for the individual Leuze end devices can be found in the following sections and in the device description.

The corresponding serial command is sent to the Leuze end device in Command mode. To send the corresponding command to the RS 232 device after activating the Command mode in byte 0 (control bit 0.0), set the corresponding bit in byte 2.

The Leuze end device also responds to most commands by sending data, such as the bar code contents, NoRead, device version, etc., back to the gateway. The answer is not evaluated by the gateway, but is instead passed on to the PLC.

For the BPS 8, AMS and hand-held scanners, a number of specific features are to be noted.

16.1 Standard setting, KONTURflex (S4 switch position 0)

This switch position can be used with almost all devices, since a data frame is transmitted along with it if necessary. A 00h in the data range of the control is interpreted as the end of a telegram/invalid, however.

The distance between two successive telegrams (without frame) must be more than 20 ms in this switch position, since there is otherwise no clear separation between them. If necessary, the settings have to be adjusted on the device.

Leuze measuring sensors with RS 232 interface (such as a KONTURflex Quattro RS) do not necessarily use a telegram frame, which is why these are also operated in switch position 0.

Specifications for the serial interface

Default parameter Standard

Baud rate 9600 Data mode 8N1 Handshake no Protocol framing protocol without acknowledgment Frame <Data> Data mode transparent

Notice!

The data frame is specified via the switch position. Only the data mode and the baud rate can also be set via the GSD file. In the factory setting, the S4 switch position is 0.
