Bus Link
"FF Link" bus link
The "FF Link" bus link acts as gateway between a PROFIBUS DP master system and a
FOUNDATION Fieldbus H1 segment and enables integration of FF devices in SIMATIC
PCS 7. The FF Link comprises one or two IM 153-2 FF interface modules and one FDC 157
Field Device Coupler, or a redundant FDC 157 coupler pair which are interconnected via
passive bus links, or in a redundant configuration via bus modules.
IM 153-2 FF
In the FF Link, the two bus systems are non-interacting through the IM 153-2 FF both physically
(galvanically) and in terms of protocols and time.
For operation with two IM 153-2 FF interface modules, the sublevel FF bus system can be
connected to a SIMATIC S7‑400H. For this purpose, the configuration always contains bus
modules.
FDC 157
The Field Device Coupler FDC 157 is the physical link to the FOUNDATION Fieldbus. The
FDC 157 provides integrated diagnostic functionality.
The use of two FDC 157 enables redundant operation on an FF segment in ring redundancy
with the active field distributor AFD, or in coupler redundancy with the active field distributor
AFS.

Product overview
2.2 Integration in the automation environment
In the case of greater distances of the inputs and outputs from the automation system the
wiring may be very extensive and confusing. Electromagnetic interference may be impair
reliability.
Distributed I/O is suitable for use with systems of this kind.
● The PROFIBUS DP master is located in a central position.
● The distributed I/O devices (inputs and outputs) work at their decentral locations.
● With its high transmission speed, the high performance PROFIBUS DP ensures that the
control system CPU and the distributed I/O devices communicate smoothly.
What is PROFIBUS DP?
PROFIBUS DP is an open bus system to IEC 61784-1 CP 3/1 with "DP" transmission protocol
(DP stands for Distributed Peripherals).
Physically PROFIBUS DP is implemented either as an electrical network based on shielded
twisted-pair cables, or as an optical network based on fiber optic cable.
The "DP" transmission protocol facilitates very fast cyclical data exchange between the control
system CPU and the distributed I/O devices.
What is FOUNDATION Fieldbus?
FOUNDATION Fieldbus is an open bus system that permits the use of field devices from
different manufacturers within one system. In many aspects, the design of an FF system
corresponds to that of the IEC fieldbus model. The FF-H1 bus works in accordance with
specifications in IEC 61158-2.
The FF-H1 bus also enables applications in potentially explosive atmospheres.
Transmission from FOUNDATION Fieldbus conforms to the international standard
IEC 61784‑1 CP 1/1.
FOUNDATION Fieldbus enables transmitters and actuators in potentially explosive
atmospheres to communicate with the automation system over long distances. With the
FOUNDATION Fieldbus, the field devices can be fed via the data cable at the same time.
The FF Link is available as gateway between the PROFIBUS DP and FOUNDATION Fieldbus
transmission technology.

The Field Device Coupler FDC 157 provides the gateway from PROFIBUS DP to the
FOUNDATION Fieldbus H1 (hereafter referred to as FF) to which the FF devices are
connected.
Both the Link Master (IM 153-2 FF interface module) and the FDC 157 Field Device Coupler
can be set up for redundant operation. A link pair (redundant power conditioning) is
interconnected with an FF segment via active AFS field distributor. An FF segment can be
configured as ring topology with the help of the active AFD field distributor. Ring redundancy
enhances the availability of the FF segment and also includes link redundancy.

Description of the components

Bus Link
Applications
The FF Link is intended for the following applications:
● S7 standard operation on S7-400
● Redundant operation on S7-400H
● FF Link Master operation
Operating principle
● The FF Link is a DPV1 slave on the higher-level DP master system and acts as a proxy for
the nodes connected on the underlying bus system (FF devices).
● The IM 153-2 FF can only be operated as DPV1 slave. A suitable DP master is required
for this. In STEP 7, the mode for the DP master being used can be selected in the Object
Properties, if required: This must be "DPV1".
● The FF Link forms an independent underlying bus system together with the connected FF
devices, which is decoupled from the higher-level DP master system in terms of
communication.
● Within the FF segment, the IM 153-2 FF (as the FF Link Master) deterministically controls
the distributed communication by means of the LAS (Link Active Scheduler). This allows
the FF devices to take over process control functions (CiF, Control in the Field).
● CiF functionality does not depend on the availability of the DP segment, which means that
the failure of the DP segment does not impair CiF functionality on the FF segment.
● The use of two FDC 157 Field Device Couplers in the redundant configuration increases
the availability of the FF segment.
Configuration options
A DP master system can be extended by means of the FF Link in the following way:
● The number of bus links on a DP master system is restricted by:
– the maximum number of bus nodes supported by the DP master system
– the number of configurable station addresses (refer to section Setting the PROFIBUS
address of the IM 153-2 FF (Page 33)).
● The FF Link comprises one or two IM 153-2 FF interface modules and one FDC 157 Field
Device Coupler, or a redundant FDC 157 coupler pair.
● You can connection a maximum of 31 FF devices on an FF Link. Each FF device occupies
a slot in the configuration.
FF Link
Operating Instructions, 03/2015, A5E35651245-AB
15
Description of the components
3.1 Bus Link
● The configuration frame and the user data frame of the FF Link are both derived from the
frame contents of the lower-level FF devices.
● The maximum length of the frames for I/O data on the PROFIBUS DP side is 244 bytes in
each case.
● An FF segment is limited to the size of the process image of the FF Link (max. 244 bytes
each for I/O data).
– You can distribute the 244 input bytes between the FF devices:
- Digital inputs (2 bytes per value, but max. 40 DI)
- Analog inputs (5 bytes per value, but max. 40 AI)
– You can distribute the 244 output bytes between the FF devices:
- Digital outputs (2 bytes per value, but max. 40 DO)
- Analog outputs (5 bytes per value, but max. 40 AO)
Requirements for use
● Software requirements:
– PDM V7.0 or higher and
- STEP 7 V5.5 and higher or
- SIMATIC PCS 7 V7.1 SP2 and higher
● Hardware requirements:
– The FF Link is connected via external CP 443‑5 communication processor:
- Standard CPU V4.0 or higher
- H-CPU V4.0 or higher
– The FF Link is connected via internal PROFIBUS DP interface of the CPU:
- Standard CPU V5.1 or higher
Parameterization of the FF devices
The FF devices are parameterized with the aid of SIMATIC PDM from a PG/PC, which is
connected to the higher-level PROFIBUS DP or the process control system. Additional
information can be found in Operating Manual Process Control System PCS 7, Help on
SIMATIC PDM (https://support.industry.siemens.com/cs/ww/en/view/109217860)
User data of the FF Link
The DP user data frame of the FF Link depends on the number of configured FF devices. It
comprises the data blocks of the configured FF devices arranged one after the other. The data
blocks are sorted in ascending order according to FF address.
In accordance with the FOUNDATION Fieldbus guideline (refer to section Standards and
Approvals (Page 85)), each process variable is assigned a status byte that specifies the status
of the process variable.
If one FF device fails, first the relevant input data are reset, including the status byte in the
user data frame of the FF Link. Then the corresponding information is entered into the
diagnostic frame.

FF Link are again available. The status byte displays the valid data.
Note
The status data of the FF devices is evaluated immediately by the SIMATIC PCS 7 drivers and
diagnostic blocks and is then made available on the operator and maintenance stations.
Switchover time to FF during redundancy mode
When there is a master-standby switchover or the active IM 153-2 FF fails, the FF devices are
processed via the standby IM 153-2 FF.
The I/O states are retained during the failover of IM 153-2 FF modules that are operated in
redundant mode. Without changes to the FF configuration, the maximum failover time amounts
to 70 ms.
The failover time denotes the interval between activation of the standby IM and availability of
the input data.
Communication links from the PG / PC to the FF devices
You can communicate with the FF devices via the FF Link by means of SIMATIC PDM .
For more information, refer to the Process Control System PCS 7, FOUNDATION Fieldbus
(www.siemens.com/pcs7-documentation) Commissioning Manual.
During redundancy mode all the communication links from the PG / PC to the FF devices
remain intact when the active channel is switched over from one IM 153-2 FF to the other.

Configuration variants with FF Link as a bus link
Introduction
You can set up a maximum of 2 IM 153-2 FFs and 2 FDC 157 Field Device Couplers (redundant
coupler pair).
● For operation with redundant IM 153‑2 FF modules, you need the BM IM/IM (redundant)
bus module.
● As far as the hardware and firmware is concerned, you must use identical components
(Link and coupler) for operation with ring redundancy or coupler redundancy.
● For operation with ring redundancy, you need the active field distributor AFD, the BM FDC/
FDC (redundant) bus module, and the BM PS/IM or BM IM/IM (redundant) bus module.
● For operation with coupler redundancy, you need the active field splitter AFS, the BM FDC/
FDC (redundant) bus module, and the BM PS/IM or BM IM/IM (redundant) bus module.
● For configuration variants with coupler redundancy, the FDC 157s monitor each other to
detect power failures and faults.
Field Device Coupler FDC 157
You do not need the PROFIBUS DP connections on the FDC 157 Field Device Coupler. The
IM 153-2 FF and the Field Device Coupler are connected via the S7 backplane bus.
The diagnostic function of the FDC 157 Field Device Coupler is only available in conjunction
with the diagnostics of IM 153‑2 FF.
Applications
With the FF Link, you can implement the following applications:
● Configuration variants without FF Link Master redundancy (singe IM 153‑2 FF)
– Use without coupler redundancy (1 x FDC 157)
– Use with ring redundancy (2 x FDC 157) with active field distributor AFD
– Use with coupler redundancy (2 x FDC 157) with active field distributor AFS
– The FF device as backup FF Link Master
● Configuration variants with FF Link Master redundancy (redundant IM 153‑2 FF)
– Use without coupler redundancy (1 x FDC 157)
– Use with ring redundancy (2 x FDC 157) with active field distributor AFD
– Use with coupler redundancy (2 x FDC 157) with active field distributor AFS
– The FF device as backup FF Link Master

Note
Design
● With redundant components, the following must be identical for the respective partner
component:
– Article number
– Hardware version
– Firmware version
● Ring redundancy has been tested and approved for use with Siemens network components.
You can find additional information on this in the section "System modification during
operation (Page 63)".
Configuration variants with FF Link Master redundancy
For operation with two IM 153-2 FF interface modules, the sublevel FF bus system can be
connected to a SIMATIC S7‑400H. For this purpose, the configuration always contains bus
modules.
Both IM 153‑2 FF interface modules have the same configuration information, the same
parameterization and receive the same input data from the FF bus. Which of the two
IM 153‑2 FFs is to be active on the FF bus depends solely on the corresponding command by
the higher-level DP master. Only the activated IM 153‑2 FF sends cyclic output data to the FF
bus (send request to FF devices).
The acyclic data is independent of the cyclical data. The passive IM 153‑2 FF can also establish
connections to FF devices upon activation.
Note
Note that only one FF segment can be connected per bus link.
Reference
For further details on the configuration variants with the FF Link, refer to
● DP/PA coupler, Active Field Distributor, DP/PA Link, and Y Link Operating Instructions

LAS functionality
As a rule, the IM 153‑2 FF (as the FF Link Master) takes over the LAS functionality. You can
use multiple FF devices as backup FF Link Master for handling LAS functionality upon failure
of the IM 153‑2 FF. To do this, you must make the corresponding settings on the FF device.
In the course of configuration, the IM 153‑2 FF is automatically used as the "primary" FF Link
Master. However, the scheduler (processing schedule for communication on the FF segment)
is loaded into each additional FF Link Master. Thus, in the event that the IM 153‑2 FF fails
(e.g. power failure), another FF Link Master will take over the LAS functions. FF Link Master
redundancy is always given in a configuration variant with 2 x IM 153-2 FF.
It is prerequisite for all variants of FF Link Master redundancy to safeguard the supply to the
FDC 157 Field Device Coupler (Power Conditioner) in order to maintain the bus supply (or at
least one FDC 157 for coupler redundancy).

Electrical isolation and grounding
Introduction
You can wire the 24 V power supply to the described modules for grounded or ungrounded
configurations, depending on the requirements of your system configuration.
Properties of the IM 153‑2 FF
● The S7 backplane bus and 24 V power supply are connected to the same potential
● PROFIBUS DP is electrically isolated from the 24 V power supply and the S7 backplane
bus
Properties of the FDC 157 Field Device Coupler
● The S7 backplane bus and FOUNDATION Fieldbus are electrically isolated from the 24 V
power supply of the FDC 157 Field Device Coupler
● The S7 backplane bus is electrically isolated from the FOUNDATION Fieldbus
Power supply
If IM 153‑2 FF and the FDC 157 are operated on the same power supply, the potential of
IM 153‑2 FF between the backplane bus and the 24 V power supply overrides the electrical
isolation of the FDC 157 Field Device Coupler between the 24 V power supply and the S7
backplane bus. To avoid this situation, you must install two electrically isolated 24 V power
supplies.
Note
In an ungrounded configuration with common power supply, observe that the FDC 157 has an
additional internal 10 MOhm resistance that is active in parallel to the 10 MOhm resistance
between electrical ground and earth on the IM 153-2 FF.

The maximum conductor cross-section is 2.5 mm2. A strain relief is not available.
Redundancy mode
For operation of an FF segment with two IM 153‑2 FF (redundant), we recommend the use of
a separate power supply for each IM 153‑2 FF.
To ensure availability in coupler redundancy mode, it is similarly recommended to provide a
separate power supply for each FDC 157.

Overview for commissioning the FF Link
Requirements
The following requirements must be met before you commission the FF Link:
● You have completely installed and connected the FF Link (1 or 2 IM 153‑2 FF and 1 or
2 FDC 157 Field Device Couplers).
● You completed the installation of PROFIBUS DP. PROFIBUS DP is ready for operation.
● You terminated the FF bus cable. FOUNDATION Fieldbus is ready for operation.
Commissioning the FF Link
1. Configure the FF Link using the "FF Link" entry in the hardware catalog.
2. Set the PROFIBUS address of the IM 153-2 FF modules.
3. Set the bus address of the FDC 157 Field Device Coupler to "0" (= default) and select
redundancy mode.
4. Switch on the power supply to IM 153‑2 FF and to the FDC 157 Field Device Coupler(s).
5. Download the configuration to the target system.
Configuration of the FF Link
Configuration is the planning and parameterization of the FF Link, FF bus, and FF devices on
the FF segment. Use STEP 7 and SIMATIC PDM to configure the system.
The FDC 157 Field Device Couplers are transition points between the S7 backplane bus of
the IM 153‑2 FF and the FOUNDATION Fieldbus with the FF devices. For FF operation, set
up the FDC 157 Field Device Coupler(s) implicitly based on the configuration of the FF Link.
Reference
For more information about the steps for configuring and commissioning an FF Link bus link,
refer to the Process Control System PCS 7, FOUNDATION Fieldbus (http://

Startup/operation without CPU
Introduction
The FF bus parameters and LAS data (schedule) can be loaded to the FF Link and the FF
devices using SIMATIC PDM or HW Config. The data is stored retentively in those applications.
Due to the retentivity of the saved FF parameter assignments in the FF Link and in the FF
devices, the FF bus starts up automatically after Power ON.
Requirements
All FF devices are configured, the FF bus is running and is controlled by the FF Link (with CiF,
if applicable).
Startup scenarios without CPU
During power up without CPU, only non-cyclic communication with the FF devices is possible
via SIMATIC PDM that is connected directly to PROFIBUS DP, e.g. for commissioning. The
following cases are distinguished:
● FF bus parameters are missing
– The FF bus starts up with default bus parameters
● The FF bus parameters are available, LAS data (scheduler) are missing
– The FF bus starts up with the specified bus parameters
● The FF bus parameters and LAS data (schedule) are available
– If the FF devices have not received their configuration, the FF bus starts up with its
cyclical communication. However, there is no process image update and communication
between the FF devices.
– Once all FF devices have received their configuration data, the FF bus starts up with its
cyclic communication. However, there is no process image update. Output data from
the FF Link are set to "0". CiF is functioning.

Startup with CPU
Startup behavior
The following cases are distinguished:
● Once it is detected that all FF devices are available in accordance with the configuration,
all output data is transferred and all input data is reported to the CPU.
● If at least one FF device does not correspond to the configuration (not available, or incorrect
name), the startup delay is maintained. The I/O data is then enabled for all FF devices with
error-free configuration (previously "0") and relevant interrupts (removal or diagnostic
interrupt) are reported for incorrectly configured FF devices.
You must set the startup delay according to the size of your system configuration in the
properties dialog of IM 153‑2 FF.

Startup diagram of IM 153‑2 FF on S7‑400H
The two IM 153-2 FF are addressed independently during startup:
● Each DP master configures and parameterizes its assigned IM 153-2 FF (independently
from other DP masters) and sends the corresponding configuration.
● In faultless operation, the IM 153-2 FF that is connected to the subsystem of the master
CPU is activated.
● Once the partner DP master has also successfully completed the configuration,
parameterization, and transfer of all configuration data to its IM 153-2 FF, the IM 153-2 FF
is available as standby.
The IM 153-2 FF on the subsystem of the standby CPU is in passive state. On failure of
the active IM 153-2 FF fails, the partner IM can continue the processing of the FF devices.
The figure below provides a simplified overview of the mutually independent behavior of the
two IM 153-2 FF.

8.5 Handling the quality code of cyclic data
8.5
Handling the quality code of cyclic data
Quality code of cyclic data
During startup, the IM 153‑2 FF internally initializes the I/O data for FF devices with a "0" value.
This action also sets the quality code to "Bad".
Once an FF device has been identified (correct name and address), its output data is
transferred to the FF bus by the DP master, while the FF device transfers the input data to the
DP master. (A special feature during the startup delay time is that the output data is retained
at "0" status.)
Upon failure of an FF device, the I/O data and the quality code will be deleted (= "0").
On failure of the higher-level DP master (e.g. transition from RUN to STOP, DP cable
disconnected, CPU switched off), all output data and the quality code will be deleted (= "0").
During normal operation (CPU in RUN), the output data is transferred in a transparent
operation.
In normal operation, the input data is adapted (alignment with the PROFIBUS PA definition):
● Quality codes 0x84 ... 0x87 are mapped to: 0x80 ... 0x83
● Quality codes 0x90 ... 0x93 are mapped to: 0x80 ... 0x83

IM 153-2 FF replacement
Replacing a faulty IM 153-2 FF
Take the following steps to replace a faulty IM 153-2 FF.
1. Switch off the power supply to the faulty IM 153-2 FF.
2. Disconnect the faulty module from the power supply.
3. Remove the bus connector from the PROFIBUS DP interface of the faulty module.
4. Replace the faulty module.
5. Set the PROFIBUS address of the new IM 153-2 FF.
6. Plug the bus connector into the PROFIBUS DP interface of the new module.
7. Connect the new module to the power supply.
Note
When replacing a single IM 153‑2 FF, you must also load the FF bus parameters and LAS
data (scheduler) in the interface module.
With active CiF: When replacing a single IM 153‑2 FF, you must also load the FF bus
parameters and LAS data (scheduler) to the interface module before you install the IM in
the system. (With CiF, it is not necessary to load the FF devices with this data; for more
information, see section Control in the Field (CiF) (Page 64)).
Implementing a used IM 153‑2 FF
To use an IM 153‑2 FF that was already in use in a different system, you must first restore it
to the factory settings.
For more, see section Restoring IM 153-2 FF to factory state (Page 59).
With IM 153‑2 FF in redundant mode
On a SIMATIC S7-400H, you can hot-swap modules when operating in redundant mode.
Observe the following special features:
● Insertion and removal of an IM 153-2 FF is only allowed in off-voltage state. Accordingly,
switch off the DC 24 V supply of the IM 153-2 FF. To prevent the underlying FF segment
from failing, the FF Link should be configured with independently switchable voltage
supplies to the two IM 153-2 FF (for example by using two voltage supply modules).

Service and maintenance
9.2 Replacing the Field Device Coupler FDC 157
In redundancy mode, it is not necessary to load parameters to the new IM 153‑2 FF if the
partner IM 153‑2 FF is still running.
Note
When replacing the active IM 153‑2 FF ("ACT" LED on), the FF Link will only continue to run
smoothly if the BF LED is not lit up or flashing on the passive IM 153-2 FF, or if the SF LED is
not flashing in 0.5 Hz cycles.
9.2
Have you replaced an active IM 153-2 FF ("ACT"
LED is On)?
Have you replaced a passive IM 153-2 FF ("ACT"
LED is Off)?
In this case, in the FF Link there was a switchover
to the other IM 153-2 FF and this also upholds the
data traffic to its DP master.
No change in data traffic
The active IM 153-2 FF has maintained the data
traffic to its DP master.
Replacing the Field Device Coupler FDC 157
Replacing a faulty Field Device Coupler FDC 157
Note
Replacement of a single FDC 157 leads to the failure of all FF devices.
To replace a faulty Field Device Coupler FDC 157, perform the following steps:
1. Disconnect the faulty module from the power supply.
2. Disconnect the FOUNDATION Fieldbus connection of the faulty module.
3. Replace the faulty module.
4. Set the bus address "0" using the DIP switches, if applicable (= default setting).
5. Set the redundancy mode correctly via the "RING" DIL switch, if applicable.
6. Set the FF bus terminator switch correctly.
7. Wire the FOUNDATION Fieldbus to the new FDC 157.
8. Wire the power supply to the new FDC 157.
Note
Removal/failure of a Field Device Coupler FDC 157
It is only possible to remove a Field Device Coupler FDC 157 if it is de-energized.
If you remove a live Field Device Coupler FDC 157 you possibly trigger the overvoltage
protection. You can reset this switch-off if you turn off the mains for at least 10 seconds.
Prior to removing a Field Device Coupler FDC 157, disconnect its 24 V DC power supply.

9.5 Restoring IM 153-2 FF to factory state
For operation with coupler redundancy
It is possible to replace an Field Device Coupler FDC 157 during operation with coupler
redundancy. The FF devices that are connected to the redundant FDC 157 coupler pair remain
in operation. The following special characteristics should be noted:
● The ACT LED of the Field Device Coupler FDC 157 must not be lit. Otherwise several FF
devices or the FF segment could fail.
● An FDC 157 may only be removed and inserted if it is de-energized. Switch off the 24 V
DC supply to the FDC 157 for this purpose. To prevent the underlying FF segment from
failing, the FF Link should be configured with independently switchable voltage supplies to
the two FDC 157 (for example by using two voltage supply modules).
9.3
Replacing active field distributors
Reference
When replacing an AFD or AFS, strictly follow the instructions in the DP/PA Coupler, Active
Field Distributors, DP/PA Link, and Y Link Operating Instructions.
9.4
Firmware update of the IM 153-2 FF
When should you update the IM 153-2 FF?

Redundancy with IM 153-2 FF
Usage
You can operate the IM 153-2 FF of the FF Link on the SIMATIC S7-400H redundantly (e.g.
CPU 417-4H).
Requirements
● Installation of active bus modules
The BM IM/IM bus module (redundant) (6ES7195‑7HD80‑0XA0) ensures high FF Link
availability and short switchover times with redundancy.
● Mutually redundant components are identical in terms of hardware and firmware.
● 2 x IM 153‑2 FF on bus module BM IM/IM (redundant)
The installation rules specified in section "Mounting (Page 27)" apply for the active bus
modules and interface modules used.
● In the redundancy mode, the same PROFIBUS address must be set for both IM 153-2 FF.
● Always interconnect the left IM 153‑2 FF interface module of the FF Link to rack 0 of the
fault-tolerant system.
Note
The SYNC/FREEZE function must not be activated during the redundancy mode.
Note
Configuration
With redundant components, the following must be identical for the respective partner
component:
● Article number
● Hardware version
● Firmware version

Identification and maintenance data (I&M data)
Definition and features
Identification and maintenance data (I&M) is information stored in a module to support you in
● Checking the plant configuration
● Locating hardware modifications in a plant
● Correcting errors in a plant
Identification data (I data) are information on the module, such as order number and serial
number, some of which are printed onto the module housing. I data are manufacturer
information about the module and are for reading only.
Maintenance data (M data) are system-related information, such as the installation location
and installation date. M data are created during configuration and written onto the module
where they are saved retentively.
Modules can be uniquely identified online by means of the I&M data.
This data is available on IM 153‑2 FF.
Reading and writing the I&M data with STEP 7
In STEP 7 the I&M data are displayed in the "Module status - IM 153-2 FF" and "Properties DP slave" tabs (please refer to the STEP 7) online help.
The M data of modules can be entered in HW Config (for example in a dialog box during
configuration).
The I&M data are accessed in accordance with the IEC 61158-6 standard.
The interface module from which the I&M data is to be read must be available online.

Control in the Field (CiF)
Control in the Field (CiF)
The "Control in the Field" (CiF) FF function enables you to control the I/O blocks between the
FF devices on an FF segment without CPU intervention, i.e. without transfer to the process
image. Control loops are also possible. Control of the data transmission is taken over by the
IM 153‑2 FF as an FF Link Master or LAS on an FF segment; or by an FF device that also has
Link Master functionality.
In this context, CiF functionality runs regardless of whether or not the DP segment or
IM 153‑2 FF is available. The DP segment, for example, can be disconnected from the
IM 153‑2 FF without disrupting the CiF function.

CiF versions
● IM 153‑2 FF is FF Link master:
– The IM 153‑2 FF and FDC 157 Field Device Coupler must be switched on
– PROFIBUS DP is not required
● The FF device is the FF Link master:
– The Field Device Coupler FDC 157 must be switched on
– IM 153‑2 FF is not required
In this case, if the higher-level system (including IM 153‑2 FF) is switched on
subsequently, it must be configured to match the FF segment running in CiF mode.
Otherwise, the CiF function will fail (failure of FF devices or FF segments).
After power was cycled OFF/ON at the IM 153‑2 FF or Field Device Coupler FDC 157, the CiF
function is resumed because the scheduler is retentive (refer to chapter Startup behavior in
non-redundant mode (Page 54)).

IM 153‑2 FF occupies slot 0 (also in redundant mode with 2 x IM 153‑2 FF).
● Slot 1
Slot 1 is needed to send IM 153‑2 FF-specific messages, e.g. in the event of a CiR conflict.
● Slots 2 and 3
Slots 2 and 3 are required for diagnostic communication of the FDC 157 Field Device
Coupler(s).
– For operation without ring or coupler redundancy: Slot 2
– For operation with ring or coupler redundancy: Slot 2 = left FDC 157, slot 3 = right

11.2 Diagnostics of the FF Link
Slave diagnostics of the IM 153-2 FF
Slave diagnostics behaves in accordance with IEC 61784-1 CP 3/1. Depending on the DP
master, this data can be read using STEP 7, SIMATIC PDM or any other configuration tool.
The IM 153‑2 FF supplies the diagnosis for itself, the Field Device Coupler FDC 157, and the
FF devices.
If the IM 153‑2 FF fails, the CPU sets the quality code for all FF devices to "Bad" in the process
image.
Diagnosis of the Field Device Coupler FDC 157
The IM 153‑2 FF can detect the following errors for the FDC 157:
● Failure of the FDC 157
● Discrepancies with the configuration of the FDC 157
● External errors, e.g. short circuit or open circuit on the FF connection side of the FDC 157
These errors are reported by the IM 153‑2 FF in its diagnostics.
Note
If diagnostics of the FDC 157 and FF devices are available, you should first evaluate the
diagnostic messages of the Field Device Coupler FDC 157 and clear the fault.
Diagnostics of the FF devices
The IM 153‑2 FF can detect the following errors for each FF device:
● FF device not available (address not found)
● Name ("Physical Device (PD) Tag") does not match address (configuration error).
These errors are reported by the IM 153‑2 FF in its diagnostics. If an FF device fails, the quality
code of the FF device is set to "Bad" in the input data by the IM 153‑2 FF.
Diagnostic frame
In the above diagnostic events, relevant IDs are set in the DP diagnostic frame in the identifierrelated and module-specific ranges. In addition, swapping and diagnostic interrupts are
triggered. Details can be found in the following sections.
Further preparation of the diagnostics data is handled by means of the PCS 7 "Advanced
Process Library" (APL) in the CPU. One module block per channel checks the quality code of
the channel and issues an interrupt if necessary.

11.2 Diagnostics of the FF Link
You can read additional diagnostics data from the FF device using the diagnostic page of the
faceplate on the PCS 7 Maintenance Station.
Note
The diagnostics data of the FF devices can only be read using the Maintenance Station or
SIMATIC PDM.
If a new configuration does not match the version of the FF device, neither the FF Link nor the
CPU will detect it. Active verification can be performed with SIMATIC PDM.

These interrupt types are not generated in IM 153‑2 FF.
Additional interrupt information for diagnostic interrupt
IM 153‑2 FF must generate the interrupt-specific data for FF devices. The ID 0xFF and cause
of diagnostics are always entered at the beginning of the auxiliary interrupt data (ID in byte x
+4, cause in byte x+5).
For redundant IM 153-2 FF, the active IM 153‑2 FF reports the event, even for the passive
IM 153‑2 FF.
IM 153‑2 FF reports the following diagnostic interrupts:
● For the IM 153‑2 FF (slot 1):
– 0x02 = configuration error (e.g. inconsistency between the DP configuration and the
retentive FF configuration in IM 153‑2 FF)
– 0x04 = external error, PROFIBUS address differs from the one used at startup; the
redundant IM 153-2 FF has a different PROFIBUS address
● For the Field Device Coupler FDC 157 (slots 2 and 3):
– 0x02 = configuration error (e.g. configuration data does not match the hardware
configuration)
– 0x04 = external error, short-circuit or wire break
– 0x08 = loss of ring redundancy (open ring, e.g. caused by a short-circuit, cable break
between 2 AFD, or failure of an AFD)
● For the FF devices (slots 4-34):
– 0x02 = incorrect assignment of the "Physical Device Tag" (name) to the configured FF
device (address)
Additional interrupt information for remove/insert interrupts
When an FDC 157 or an FF device on the underlying FF bus fails or is restored, the IM 153-2
FF triggers a remove or insert interrupt on the higher-level DP master system.
The FF address of the mapped FF device is entered in the additional interrupt information (in
byte x+4); in FDC 157 the value "0" is entered (in byte x+4).

11.4 Reading out diagnostics from FF devices
Field Device Coupler FDC 157 (slots 2 and 3)
The remove interrupt for the Field Device Coupler FDC 157 is generated if:
● On expiration of the startup delay time of IM 153‑2 FF, the FDC 157 cannot be reached
● Communication to the FDC 157 breaks off during operation.
The insert interrupt for the Field Device Coupler FDC 157 is generated if:
● An new FDC 157 is detected during operation.
In the non-redundant case, the loss of power to the Field Device Coupler FDC 157 would be
reported as a remove interrupt. In addition, the connected FF devices are also reported as
failed (remove interrupt).
In the case of redundancy, the two FDC 157 Field Device Couplers monitor each other and
detect errors. Here, a loss of power to a Field Device Coupler FDC 157 is also reported as a
remove interrupt. Due to the redundant coupling setup, the communication to the FF devices
is maintained.
FF devices (slots 4-34)
The remove interrupt for FF devices is generated if:
● On expiration of the startup delay time of IM 153‑2 FF, a configured FF device is not found
on the FF bus
● An FF device is no longer recognized in operation
The insert interrupt for FF devices is generated if:
● A configured FF device is newly detected in operation based on its address.
The following table shows the relationship between remove/insert interrupts and diagnostic
interrupts for FF devices.

Reading out diagnostics from FF devices
Overview
The diagnostic data of the FF devices can only be read out with SIMATIC PDM.
SIMATIC PDM displays the status of FF devices which generate their diagnostics data in
accordance with the FOUNDATION Fieldbus guideline (refer to chapter Standards and
Approvals (Page 85)).

Alarm, error, and system messages
11.4 Reading out diagnostics from FF devices
The diagnostic information alongside the status byte (quality code) made available by the FF
device (e.g. device state) is implemented accordingly and the system is made available.
This makes it possible to access FF devices object-specifically. A direct path is created to the
asset management here, i.e. FF devices are available in the maintenance station as individual
objects for cyclic diagnostics through automatic linking. Non-cyclic diagnostics is also possible
by means of SIMATIC PDM.

Address
The address of a node is used for locating it in the network. It has to be unique in the entire
network.
Aggregate current
Aggregate current of all PA or FF field devices.
Automation system
An automation system is a programmable control system, consisting of at least one CPU,
various input and output modules as well as operating and monitoring devices.
Bus
A common transfer route to which all nodes are connected; it has two defined ends.
Bus connector
Physical connection between the bus node and bus cable.
Control in the Field (CiF)
The FOUNDATION fieldbus function "Control in the Field" (CiF) provides the option to control
I/O blocks between FF devices on an FF segment without CPU intervention, i.e. without
transfer to the process image. Control loops are also possible.
The Link Active Scheduler (LAS) controls data transmission on the FF segment.
Diagnostic interrupt
Diagnostics-capable components report system errors they have detected to the central CPU
by means of diagnostic interrupts.
In SIMATIC S7: When an error is detected or disappears (e.g. wire break), provided the
interrupt is enabled, the module initiates a diagnostic interrupt. The CPU interrupts the
processing of the user program and lower priority priority classes and processes the diagnostic
interrupt block (OB 82).
In SIMATIC S5: The diagnostic interrupt is shown within the device-related diagnostics You
can identify errors, such as wire break, by cyclically scanning the diagnostic bits.

Glossary
PROFIBUS DP
PROFIBUS bus system with the DP protocol. DP stands for the German equivalent of
distributed I/O.
PROFIBUS PA
PA stands for Process Automation and increases the range of usage of the PROFIBUS DP
family to include the field of process engineering. Process engineering refers to both the
intrinsically safe sectors of the chemicals industry and to the non-intrinsically safe sectors,
such as nuclear power plant automation, the food industry and waste water technology.
Redundant systems
Redundant systems are characterized by the multiple (redundant) presence of important
automation components. If a redundant component fails there the processing of the program
is not interrupted.
Reference potential
The potential to which voltages of participating circuits are referenced when they are viewed
and/or measured.
Scheduler
The scheduler is used on the FOUNDATION Fieldbus to specify the time at which an FF device
transmits or reads cyclic data. The scheduler helps to a avoid conflicts in publisher/subscriber
communication on the FF segment.
Segment
A segment or bus segment is a self-contained section of a serial bus system.
SELV
Safety extra low voltage (SELV) is voltage < 30 V AC / 60 V DC that is generated by means
of safety transformer, accumulator etc.
SIMATIC PDM
SIMATIC PDM (Process Device Manager) is a universal tool that is not manufacturer-specific
and is used for configuring, parameterizing, commissioning and diagnosing intelligent process
devices. SIMATIC PDM makes it possible to configure a large variety of process devices with
a single software on a standardized user interface.
Terminating resistor
A terminating resistor is a resistor that terminates the data transmission line to avoid
reflections.

Glossary
Time synchronization
Time synchronization ensures that all clocks run synchronously. A master clock distributes the
time in a configurable cycle to all other components in the automation system that have a clock.
The components use this distributed time to set their own clocks.
TN-S system
In a TN-S system, the neutral conductor (N) and protective conductor (PE) are routed
separately from each other. The neutral conductor is connected to the grounded protective
conductor at a central point, and only there. The conductor can be grounded any number of
times.
Token
In network technology a token refers to a bit pattern that is passed from one bus node to
another, enabling that node to access the bus.
Transmission speed
The transmission speed specifies the number of bits transmitted per second.
Type of ignition protection
The special measures applied to electrical equipment to prevent the ignition of an ambient
potentially explosive atmosphere.
Ungrounded
Having no conductive connection to ground
Update
Following (compatible) functional extensions or improvements to performance you should
update the IM 153-2 interface module to the respective most recent firmware version.
