3 Configuration information
This chapter contains indications and information required for successful installation of your system in a Profibus-DP network. General field bus information relevant to configuration, installation and operation of FD67 systems can be found in the following manuals :
FD67 – System manual FD67 – Technical manual
3.1 FD67 in a Profibus-DP network
FD67 is a modular I/O system designed for decentralized gathering and processing of digital and analogue process variables. It is made up of a field bus specific bus node and field bus-oriented I/O modules, which are connected to the bus node via internal system connection.
3.1.1 System components
Min. configuration of a Profibus-DP network :
- one or several bus masters.
- one or several slaves.
- Profibus cables and plugs to interconnect the system units.
- one ore several bus segments linked up by repeaters.
3.1.1.1 Profibus cables
Use only A-type cables, according to EN 50 170 part 8-2. Type B cables are obsolete and should basically not be used.
Parameter A-type cable
Impedance level / Ω
135 to 165 at a frequency of 3 to 20 MHz
Operating capacity (pF/m)
≤ 30
Loop resistance (Ω/km)
≤ 110
Wire diameter (mm) > 0,64 Wire cross section (mm2) > 0,34
The wire cross section used must fit the connection possibilities on the bus connector.
6
3.1.2 General information for successful planning in a Profibus network
Up to 32 units (including repeaters) are allowed in a bus segment.
According to the selected baud rate, the extension of a Profibus segments must not exceed the max. recommended values ; see Table 3-1.
Repeaters can be used to divide a network into several segments. So it is possible to operate more than 32 units in an extended Profibus network. However signal delays resulting from the installation of repeaters must be considered during configuration of the system. Up to 9 repeaters can be installed between two units.
3.1.3 Topology
♦ Fig. 3-1 : Example of a Profibus network
3.1.4 Termination of bus segments
Both sides of a segment must be fitted with a terminal resistor. The terminal resistors must be supplied to guarantee a correct physical signal level.
The terminal resistor is either located in the connector or directly integrated into the device. In both cases it must be observed that in case of failure or application-related voltage cut-off of the unit at the end of a segment, the terminal resistor may also be switched off to the detriment of the operatability of the whole segment.
So it might be preferable to install be bus master at the beginning or the end of the bus segment. In case of breakdown of the bus master, the switching off of the terminal resistor is of no importance. Additional repeaters or externally supplied terminal resistors may be installed for reliable termination of the other end of the segment. The need of additional measures must be determined for ev ery specific case.
Fig. 3-1 shows an example of correct termination in a typical Profibus network.

3.1.5 Baud rate
All the devices in a Profibus network use the same baud rate set by the bus master. It is automatically recognized by the FD67 bus node.
According to the selected baud rate, the max. admissible cable lengths must be observed (see Table 3-1 below). These values relate to a single bus segment. By using repeaters, it is possible to achieve greater network extensions over several segments.
Baud rate in kBit/s 9,6 19,2 45,45 93,75 187,5 500 1500 3000 6000 12000 Cable length in m 1200 1200 1200 1200 1000 400 200 100 100 100
♦ Table 3-1 : Max. admissible cable lengths in a Profibus segment
3.1.6 Address
Profibus user addresses range from from 0 to 125. The two address switches of the FD67 bus node allow to set addresses from 0 to 99.
It is important to ensure that an explicit and unique address is assigned to each Profibus user. The Profibus address is set directly at the FD67 bus node via two BCD switches that are integrated into to the base module.
The set address is read in once after a voltage reset. A change of address in operation is not supported.
Detailed information can be found in the FD67 System manual.
3.1.7 Spur lines
As a rule, passive spur lines should be avoided.
If spur lines are required, e.g. for temporary connection to programming or diagnostic dev ices, use active spur lines or repeaters. Correct termination must always be assured.
3.1.8 Design guidelines
Design guidelines have been issued by the Profibus User Organization (PNO). They must be strictly observed, as well as the information contained in the FD67 manuals. See the PNO homepage :
www.profibus.com

4 Mounting and wiring
Installation and wiring information relevant to I/O modules and internal system connection can be found in the manual FD67 – Technical manual.
CAUTION : Mounting, wiring and setting of the Profibus address must be performed while the equipment is not under power.

a) Mounting the base module of the bus node
Attach the module to the mounting holes by means of the 2 fastening screws 4 mm in diameter.
The tightening torque is : 2 Nm.
b) Setting the Profibus address
Two address switches are provided to set the bus node address in the Profibus network. Values between 1 and 99 are allowable.
Two units in a Profibus network must be clearly identifiable ; therefore they must not be allocated to the same address. The set address is read in once after the supply voltage is applied. Therefore, a change of address only takes effect after a module voltage reset.

4.2 Assembling the hood of the bus node
Before assembling the hood, it is advisable to set the Profibus address, because the switches are no more accessible when the hood is attached. It is also recommended to note the set Profibus address on a label plate.

The FD67 System is normally configured using a configuration tool supplied by the master's manufacturer. Then you don't have to worry about the technical details described in this chapter. You can find a configuration examples in Chapter 5.3.4 and Chapter 6.
The configuration message, which defines the number of input and output bytes, is sent from the master to the slave during the startup procedure.
FD67 uses the special ID format according to IEC 61158.
FD67 can only be operated on DP masters which support the special ID format.
Based on this information, the FD67 bus node checks the configuration for correctness. If the bus node detects a deviation between the required configuration transferred by the DP master in the configuration message and the actual configuration, the bus node indicates a configuration error and does not switch to data exchange with the DP master.
The configuration error is indicated visually via the Cfg F LED on the bus node. In this case, the Cfg F LED is lit red.
5.3.1 Placeholder
To maximize expandability of the FD67 System, it is possible to insert placeholders. A placeholder is a module with a data length of zero and whose sole purpose is to reserve a space for adding a module at a later date.
Note :
It is advisable to insert placeholders into the configuration for unused connectors. See Chapter 5.3.4.2.

5.3.2 Structure of a configuration string
The configuration string is transmitted to the data field of the configuration message. The IDs are entered in the order in which the modules are connected to the bus node.

5.3.3 Replacing DI modules by DIO modules
Digital I/O modules are available in two versions :
♦ DIO : each channel can be configured as Input or Output ♦ DI : each channel is an Input
DIO modules support all the functions of corresponding DI modules. So it is possible to replace a DI module by a DIO module without modifying the Profibus configuration.
Replaceability simplifies stock keeping of spare parts. Installing DI modules is also a cost-effective solution.
If you replace an installed and configured DI module by a DIO module, the bus node will automatically recognize the DIO module and assure via the integrated replacement algorithm that it behaves like a DI module for the DP master and the application.

5.3.4.1 Configuration of compact modules
This configuration is made up of two compact modules connected to the sockets 0 and 1 of the internal system connection of the bus node.
In this type of configuration, there is no direct relationship between the module position in the configuration table (connector) and the actual location on the bus (string/position in the string). Instead of connecting the modules to the sockets 0 and 1 of the bus node, you could as well connect them to the connectors 1 and 3. You can determine the sequence and correspondence between configured modules and modules detected by the bus node at system startup.
Note :
A simple solution consists in integrating placeholders for a better general arrangement of the configuration and a clear relationship between the connector and actual module position. Configuration can be easily extended at a later date by replacing the corresponding placeholder, without any interaction on other configured modules (e.g. they keep their module number for diagnosis).

5.3.4.5 Manual assembling of a configuration string
♦ Fig. 5-1 : Configuration example
The modules are automatically addressed by the bus node in the order of connection : first all the modules connected to socket 0 of the internal system connection, then all the modules connected to socket 1 of the internal system connection and so on.
The configurations strings of the different modules can be found in chapter 5.3.2.

5.4 Parameterisation
Parameterisation allows to define the characteristics of the FD67 system and the connected I/O modules, e.g. :
♦ Function of an I/O channel (Input or Output) ♦ Enable/disable diagnosis and type of diagnosis. ♦ etc.
By using a graphic configuration tool, parameterisation is made easier thanks to the information contained in the GSD file. Refer to the documentation of the configuration tool.
With the following information, you can assemble the parameter string yourself. See chapter 8 for the coding of parameter bytes (bus node and I/O modules).
♦ Fig. 5-2 : Hardware-configurator in a Simatic S7 environment
The GSD file contains two preconfigured versions for freely configurable DIO modules.
These preconfigured versions can be used if you need only Inputs or only Outputs on this module.
