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.
17
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 Configuration examples
Configuration examples with hardware manager Simatic Step 7.
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).

5.4 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.
See also chapter 5.4.2.
26
5.4.1 Parameter message
The master sends a parameter message to the slave. The first 7 bytes are defined by Profibus standard IEC 61158. They are followed by user parameters. The number and composition of the user parameters are dependent on the configuration of the FD67 System. A plaintext message is stored in the GSD file for each parameterization function.

5.4.1.2 User parameters
Standard specific parameters are followed by a number of user parameters dependent on the FD67 structure and extension. They first include parameters for the bus node and then parameter bytes for the different modules. The sequence corresponds to the order in which the modules are connected to the bus node. See chapter 8.
Parameterisation example : bus node and FD67DIOM121216.
Requirements :
You don't want the bus node to generate a diagnosis message if the actuator supply drops below 12 V (Diagnosis „No Actuator supply“). If underv oltage of the actuator supply is monitored, no diagnosis message will be generated, ev en if in case of an actuator supply cut-off caused for example by the opening of a protection gate.
The I/O module must be parameterised as an Output at Pin 4 and as an Input with make function at Pin 2 (non-inverted input).
The user parameter string (all values in hexadecimal notation) looks like this :

5.4.2 Preconfigured modules
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.
Advantage of preconfigured modules :
♦ Addresses are allocated either in the IDM

or in the ODM5 of the PLC.
♦ Quick parameterisation during the configuration of I/O modules.

A short-circuit at the socket or in the cable of the system connection is detected. The sensor supply, and hence the module supply for this line, is switched off. The system goes over into communication error. After the short-circuit has been rectified, the internal system connection can be restarted via a voltage reset of the sensor supply. In case of inadequate power supply unit, it will be switched off before the short-circuit detection by the bus node and will initiate a reset of the bus node. The U

node is lit red for this line.
7.2.2.1.2 Short-circuit of actuator supply of internal system connection
A short-circuit at the socket or in the cable of the system connection is detected. The actuator supply for this line is switched off. After the short-circuit has been rectified, it can be cleared via a voltage reset of the actuator supply. The U

LED on the bus node is lit red for this line.
7.2.2.1.3 Undervoltage of sensor supply of internal system connection
Undervoltage is detected below approx. 17.0 V. The US displays of the lines affected are red. If the voltage drops below approx. 12.5 V, the bus node goes into reset. The bus node reconnects to the Profibus as soon as the sensor voltage rises above approx. 13.0 V.

7.3 Profibus
Diagnosis status modification of the FD67 System is reported to the DP master. The DP master then requests the diagnostic information, which is supplied in the form of the diagnosis message described below.
Some DP masters accept in standard configuration only diagnosis messages with a maximum length of 32 bytes. If possible, this value should be set to the maximum Profibus-DP supported length of 244 bytes. Otherwise, the max. length must be limited by blinding channel-related diagnosis messages (Bus node parameters, see chapter 8). In this case, a channel-related diagnosis is only reported in the form of a collective bit in the station-related diagnosis.
The diagnosis model of Profibus DP distinguishes between three layers of diagnostic information.
A plaintext message is stored in the GSD file for each diagnosis. Diagnosis messages can be masked out selectively v ia the bus node parameterization.
Example :
In an application, the actuator supply voltage is to be monitored for undervoltage, but no diagnosis is to be generated when the actuator v oltage is switched off, e.g. in an emergency stop situation.
Solution :
The parameter "No actuator supply" of the bus node is set to "Do not report'.
Result :
No diagnosis is generated if the actuator supply v oltage is less than 12 V. If the voltage is between 12 V and 18 V, the diagnosis "Undervoltage actuator supply" will be reported.
Station-related diagnosis
- Undervoltage measured at bus node
- Undervoltage measured at I/O module
- Communication fault
- etc.
ID-related diagnosis
- Information as to which modules have diagnostic capability
Channel-related diagnosis
- Short-circuit in the supply of a sensor
- Short-circuit to 0V or overload (actuator cut-off)
- Short-circuit to +24 V (actuator warning)
- Diagnosis according to DESINA
- etc.
44
7.3.1 Diagnosis Overflow
The FD67 bus node can process up to 32 channel-related diagnosis messages and report them to the DP master. In presence of more than 32 channel-related diagnosis, the Diag.ext_overflow bit (standard diagnotic information, byte 2) is set in the DP diagnosis message.
♦ Fig. 7-5 : Max. number of channel-related diagnosis
Station-related diagnosis includes one module-related diagnosis byte for each I/O module.
Bytes 10 to 25 Module-related diagnosis (1 byte for each module)

7.3.2 Structure of a diagnosis message
The diagnostic information comprises standard diagnostic information (6 bytes) and manufacturer-specific diagnostic information.
7.3.2.1 Bytes 0 to 5 : standard diagnostic information
Byte 0
7 6 5 4 3 2 1 0
Diag.station_non_existent
This bit is set by the DP master if this DP slave is not accessible (for generation of a collective diagnosis). The DP slave sets this bit to zero.
Diag.station_not_ready
This bit is set by the DP slave if the DP slave is not ready for data exchange.
Diag.cfg_Fault
This bit is set by the DP slave as soon as the configuration data previously received from the master does not match the configuration data ascertained by the DP slave.
Diag.ext_diag
This bit indicates that a diagnostic entry is present in the slave specific diagnosis area (Ext_Diag_Data).
Diag.not supported
This bit is set by the DP slave as soon as a function not supported by the DP slave is requested.
Diag.Invalid slave response
This bit is set by the DP master as soon as an implausible response is received from an addressed DP slave. The DP slave sets this bit to zero.
Diag.prm_fault
This bit is set by the DP slave if the previous parameter message was erroneous, e.g. incorrect length, incorrect ID number, invalid parameter.
Diag.master_lock
The DP slave has been parameterized by another master. This bit is set by the requester if address in byte 3 is not equal to FF
hex
and not equal to own address. The DP slave sets this
bit to zero.
46
Byte 1
7 6 5 4 3 2 1 0
Diag.Prm_req
If the DP slave sets this bit, it must be re-parameterized and re-configured. The bit remains set until a parameterization is finished.
Diag.Stat_diag
If the DP slave sets this bit, the DP master must get diagnostic data until this bit is deleted. The DP slave sets this bit when it cannot provide valid user data, for instance.
Set to 1
Diag.WD_ON
If this bit is set to 1, response monitoring is activated.
Diag.freeze_mode
This bit is set by the DP slave as soon as it receives the Freeze command.
Sync_mode
This bit is set by the DP slave as soon as it receives the Sync command.
Diag.Not_Present
This bit is set by the DP master for the DP slaves not contained in the master parameter block. The DP slave sets this bit to zero.
Diag.deactivated
This bit is set by the DP master as soon as the DP slave is removed from the master parameter block of the DP master. The DP slave always sets this bit to zero.
Byte 2
7 6 5 4 3 2 1 0
Reserved
Diag.ext_overflow
If this bit is set, there is more diagnostic information available than is specified in Ext_Diag_Data. For example, the DP slave sets this bit when there is more channel diagnostic information available than the DP slave can enter into its send buffer. The DP master sets this bit when the DP slave sends more diagnostic information than the DP master can take into account in its diagnostic buffer.
Byte 3
7 6 5 4 3 2 1 0
Diag.master_add
The address of the DP master which has parameterized the DP slave is entered into this byte. If the DP slave is not parameterized by a DP master, the DP slave sets the address FF
hex
in this byte.

7.5.1 Troubleshooting in a Profibus network
The table below shows the most current errors in a Profibus network. This list is not exhaustive. To check correct installation, there are many useful diagnostic tools (line tester, Prof ibus tester, Prof ibus monitor) offered by different manufacturers.
Error DP Diagnosis LED Display Possible cause Solution
The unit is not supplied. Supply the unit. No address is set or invalid address. Set correct address. The set address is already used. A n explicit and unique address must be allocated to each Profibus user.
The t ermin al resi stor between m aster and unit is switched on.
W hen the termin al res istor is s witched on in a Pr ofibu s c onnect or, th e next us er is disconnected from the Profibus. Make sure that only the terminal resistors located at both ends of the Profibus segmen t are s wiitc hed on.
W rong t erminat ion of the Pr ofib us s egment.
Both ends of a Profibus s egment must be fitted with a terminal resistor. If low baud rates are used, the network can apparently be operated despite wrong
termi nation . Th is may c ause s porad ic f aults in pr oduc tion oper ation. Spur lines Baud rates up to 1.5 MBit/s max. 6.6 m If higher baud rates are used, spur lines are not admissible.
If s pur lines cannot be avoided , pref erably use s pecif ic „act ive“ sp ur li nes or
repeater s. P lease n ote that the num ber of repeater s us ed in a s egment is li mited .
Refer to th e relevant docum entation of th e repeater .

8.3.1 Specific characteristics
8.3.1.1 Smoothing (Analogue input modules only)
The analogue signal can be prefiltered in the device, e.g. to reduce sensitivity to short-time measurement variations.
Measurement time per channel is 2,0 ms. The total time of a cycle results from the measurement time per channel + 2,5 ms. The graph below shows the module behav iour to the response time in an active channel.

8.3.1.2 Delta (Analogue input modules only)
This value sets the number of increments to increase or reduce the last measured value, in order to send the analogue input value from the module to the bus node. This parameter can be used to reduce the bus load of the internal system connection.
Example :
The last measured value was 1000. With a delta of 100, the next measured value will only be
sent, if it is < 900 or > 1100.

9.1 General information about the Profibus
Bus segment The electrical specification of the RS-485 interface limits the number of
users on an RS485 network to 32. If more than 32 Profibus users are to be used, then the network must be subdivided into segments by using repeaters.
DP Distributed Periphery. Profibus protocol for high-speed cyclical data
exchange.
Freeze Mode The Input data of the slave are "frozen“.
GAP factor The number of bus cycles after which a DP master searches for new
active subscribers for inclusion in the token ring. This factor can be modified to optimize the speed of a DP network.
GAP range The address range in which an active user searches for a new active
user. This range is always between the own address and the address of the next active user already in the Token Ring. The range from the highest address up to 127 does not belong to the GAP range.
GSD The devices master file describes the technical features of a Profibus
product. This file is required to configure a Profibus system, and is provided by the device's manufacturer.
ID number A 16-bit number which clearly identifies a Profibus product. It is a
reference to the GSD file. More than one device can have the same ID number, provided that the numbers can be written to a common GSD file. This number is allocated by Profibus Nutzerorganisation e.V (Profibus user organization).
IEC 61158 Globally recognized standard for Profibus DP and FMS which
supersedes the international standard EN 50 170 Volume 2.
Master Class 1 The master which carries out user data transfers.
Master Class 2 Master for control/startup and configuration tasks.
Byte Term used in IEC 61158. Equivalent to 1 byte or 8 bits.
IDM Input Data Map
ODM Output Data Map
PNO
P
rofibus Nutzerorganisation e.V. (Profibus user organisation)
Repeater Coupling element for signal conditioning between Profibus segments.
PLC Programmable Logic Controller
Sync-Mode The output data of the Slave are "frozen“.
91
Token The activ e user (master) in possession of the token can carry out data
exchange with the slaves which it has parameterized and configured. On completion of the data cycle, the active user passes the token to the next active user.
9.2 FD67 specific
Sensor short-circuit Short-circuit or overload at Pin 1 of the M12 socket causes the self-
resetting fuse to blow. Each M12 socket is separately fused. A red LED indicates the fault at the associated M12 socket. This fault is indicated via the DP diagnosis. The sensor supply restarts automatically after the fault is cleared. Please not the specific characteristics of analogue A/O modules.
Actuator cut-off Short-circuit or overload at an output causes the output to be disabled.
This fault is indicated to the DP master via the DP diagnosis. A red LED indicates the fault at the associated M12 socket. The output is not automatically re-enabled. The output or the actuator supply voltage must be disabled after eliminating the cause of the fault. This clears the short circuit memory.
Actuator warning W hen an output is disabled, the presence of 24V at the associated Pin of
the M12 socket is detected. This is an indication of a "short-circuit" to +24. A probable cause of this diagnosis is a faulty connection, i.e. a sensor was connected to a channel parameterized as an output. A red LED indicates the fault at the associated M12 socket. This fault is indicated to the DP master via the DP diagnosis. This fault does not affect activation of the output. It is not possible to detect an actuator warning when the output is enabled.
Undervoltage The voltages of the sensor supply and actuator supply are metered
separately. W hen the voltage drops below 18 V DC, a fault is indicated to the DP master v ia the DP diagnosis. When sensor supply undervoltage is detected, the LED labeled "U
S
" is lit red. When actuator supply
undervoltage is detected, the LED labeled "U
A
" is lit red. This diagnosis
can be masked out via the parameterization.
No voltage This diagnosis is indicated to the DP master when the supply v oltage
drops below 12 V DC. This diagnosis can be masked out via the parameterization.
External fault This diagnosis can only be generated by an input parameterized as a
diagnostic input. External fault is indicated when 0 V is present at this input. Sensors/actuators which meet the DESINA specification are supported. Alternately, the line can be monitored for open circuit by using a diagnosis adapter.
