3.1 Topology of a PROFIBUS PA network

The following diagram shows a typical network configuration with PROFIBUS PA devices in hazardous and non-hazardous areas, as well as the connection of conventional non-PROFIBUS devices (e.g. with 4 … 20 mA signals) to a PROFIBUS network.

The PROFIBUS PA segment is connected to a segment coupler which, among other things, provides the conversion to the PROFIBUS DP bus line. In addition it provides the power supply for bus–powered PROFIBUS PA devices. Refer to the instruction manual of the segment coupler concerning the DP bus parameters, e.g. the supported baud rates.

3.2 Electrical connection for signal converter

Bus cable - Shielding and grounding

The statements of the FISCO model only apply if the used bus cable meets the required specifications.

In order to ensure optimum electromagnetic compatibility of systems it is important that the system components, and in particular the bus cables, are shielded. These shields must have as few gaps as possible.

INFORMATION!

The PROFIBUS PA interface of the signal converter will operate only if the power supply is connected/available. The device terminal is not sensitive to electrical polarity.

4 COMMISSIONING / OPERATION

4.1 Hardware settings

There is a DIP switch block with 8 switches on the level transmitter module to set the PROFIBUS device address and prevent changes to the station address from the network.

OPTIFLEX 2200 C

Figure 4-1: How to use the DIP switches to change the station address

1 Hardware DIP switch

OFF: The user can set the station address with the network bus ON: The user can set the address of the device with the 7 other DIP swtiches (item 2). You cannot use the network bus or the local display to change the station address.

2 7 "Station Address" DIP switches. Each DIP switch is a bit position (bits 0...6). Bit 0 is on the left side of the switch

block.The base 10 value of each bit is given in the table that follows. This data is used to calculate the "Station Address" number. OFF: binary number "0". ON: binary number "1".

INFORMATION!

If the Hardware DIP switch is set to "ON", the hardware is locked and you cannot use the network bus to change the station address.

Station address

• If the "Station Address" DIP switches are set to a correct station address (≤125), the device uses this address. The Set_Slave_Add service is not used. Automatic Ident. Number adaptation is not possible via Set_Slave_Add service in this case. Physical block parameter FACTORY_RESET code 2712 (reset station address to its default value) is rejected.

• If the "Station Address" DIP switches are set to an incorrect address (>125), the device ignores this setting. The Set_Slave_Add service and the Physical block parameter FACTORY_RESET code 2712 (reset station address to its default value) are used. If No_add_Cfg flag is set to "ON", the device will continue to use FACTORY_RESET code 2712.

• If the "Station Address" DIP switches are changed from an incorrect address to a correct address, the device uses the address set on the DIP switch block.

• If the "Station Address" DIP switches are changed from a correct address to an incorrect address, the device will use the default address 126. The flag No_Add_Chg will be set back to "OFF".

INFORMATION!

You can also use the local display (menu item 2.6.1 ADDRESS) to set the Station Address to a new value. You can change the value when the Hardware DIP switch is "OFF". If the Hardware DIP switch is "ON", you can see the Station Address on the local display screen but you cannot change the value.

4.2 GSD files

The GSD file contains information that will be needed for configuration of the PROFIBUS DP communication network. Supplementary files (e.g. ___.bmp and ___.dib) contain icons which will represent the PROFIBUS devices in the view of the bus configuration system/master system. The files must be loaded into the configuration program before you connect the device to the network. Follow the instructions in the manual of the host supplier when installing GSD file and supplementary files.

The GSD files of all KROHNE devices with PROFIBUS PA interface are available at the KROHNE internet site for download.

INFORMATION!

If a different GSD file is used in the PROFIBUS master system, it is not possibe to transfer cyclic data.

4.4 Configuration of cyclic data transfer

During network configuration the user has to select which function block input/output data shall be transferred between the PROFIBUS master and the PROFIBUS slave. The GSD file described above contains several types of modules for this purpose. During configuration a module has to be assigned to each slot of the device in order to select which data has to be transferred for the corresponding function blocks. The cyclic layout (see section Ident. Number selector) shows which module types are valid for each slot. The order of transmission of the data always remains the same. If an “Empty Module” is assigned to a slot no data will be sent for the corresponding function block and all function block data following this empty module will move up one position.

4.5 Cyclic data

In a PROFIBUS network cyclic data is described from the point of view of the master. Therefore input data is transferred from the slave to the master while output data is transferred from the master to the slave.

4.5.1 Input data

Input data is transferred from the level transmitter to the master for the measuring value. If input data transfer is configured, 5 bytes are transferred for the corresponding slot:

• 4 byte float value (Float Format according to IEEE Standard 754 Short Real Number)

• 1 byte status value

Status value

Status valueStatus value

The PROFIBUS interface of the level transmitter supports the PROFIBUS-PA Profile Version

3.02. In this Profile the Condensed Status and Diagnosis has replaced by default the Classic Status and Diagnosis of the PROFIBUS-PA Profile Version 3.0. The Condensed Status and Diagnosis has been created to make diagnostic events more obvious and to allow predictive and preventive maintenance. Nevertheless Classic Status and Diagnosis is still available for the level transmitter. It is implemented for backwards compatibility to "older" devices or PLC systems which do not support Condensed Status and Diagnosis. The device may be switched between "Condensed Status and Diagnosis" and "Classic Status and Diagnosis"

• automatically during start-up of the cyclic data transfer by setting the parameter PRM_COND

within the Set_Prm service data.

• using an engineering tool (e.g. DD/DTM) to write the parameter COND_STATUS_DIAG (slot 0,

index 43).

Coding for both parameters is:

• 0: Classic Status

• 1: Condensed Status (factory setting)

COMMISSIONING / OPERATION 4

INFORMATION!

The parameter COND_STATUS_DIAG cannot be modified directly if cyclic data transfer is active. Nevertheless it is reset to the factory setting if a reset to default data is requested by an engineering tool.

The coding of the status value depends on the active status and diagnosis mode. It is described in the following tables.

Condensed Status

The Condensed Status codes have been defined to allow easier decoding of the information provided by the PROFIBUS devices. The coding is shown in the following table:

INFORMATION!

4.6 Diagnosis

The device does internal self-tests. The results are given as detailed diagnosis data that agrees with PROFIBUS PA Profile 3.02. You can set device parameters to see the diagnosis data and you can also use an engineering tool (DD/DTM, ...) to read it. Cyclic services transfer diagnosis data to the control system (PLC, ...).

Diagnosis is bitwise coded. Thus it is possible to report more than one indication simultaneously. The GSD file contains a text for each diagnosis bit to show a text message in the control system. The references are specified in the UNIT_DIAG_BIT(i) entries. They show which bit is set to indicate a special diagnosis event.

The quantity and content of diagnosis data depends on the device settings. The active Ident. Number and the selected status and diagnosis mode will have an effect diagnosis propagation. The tables that follow show the diagnosis events which are reported for different settings. The bit number is equal to the count in the GSD file. It gives the position in the device-related diagnostic field of the Slave_Diag service.
