Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.

Introduction
1.4 Hardware configuration
1.4 Hardware configuration
The driver concept for 3WL / 3VL supports operation of the circuit-breaker as a DP slave
directly connected to the DP master system as well as connected following a Y-link DPV0 or
DPV1.
The circuit-breakers in this setup can be incorporated using a GSD file.
NOTICE
In such cases ensure that the circuit-breaker's I/O data is within the control's process
image. This is absolutely essential to the driver generator's functionality.
1.4.1 Incorporating via GSD file
If the 3WL / 3VL device is incorporated via GSD SIEM80C0.gsd, it is entered in the hardware
configuration catalog under PROFIBUS-DP → Other field devices → Switchgear:
Figure 1-1 Catalog path for incorporating via GSD file
The following I/O configuration applies for 3WL:
● Outputs: 2 bytes of digital control data
● Inputs: 44 bytes of binary status (2 bytes) and measurements with property bytes (42
bytes)

Introduction
1.4 Hardware configuration
Configuration in HW config.
In the HW config., 3WL / 3VL is installed with the corresponding GSD file (see above) and
with basic type 3 and/or 1.

Introduction
1.4 Hardware configuration
If 3WL / 3VL is connected following a Y-link DPV0 or DPV1, 3WL / 3VL must be configured
in the HW config. as a DPV0 slave. All acyclic services and interrupts are deactivated. This
means that the device no longer outputs diagnostic interrupts and data records can no
longer be read from the device. For details of the effect that this has on the response of the
blocks, refer to
Section 3 Description of the blocks (Page 17).
Figure 1-5 Properties of the 3WL / 3VL device following a Y link
The start addresses of inputs and outputs must be located in the partial process image that
is assigned to the watchdog interrupt OB in which the driver block is called.
The LADDR parameter input of the driver block must be connected to the start address of
the inputs of the 3WL / 3VLdevice.
The assignment of the cyclic interface is included in the description of the driver block.

2.2.2 Symbols
The process display icons are based on the process symbols provided by the Faceplate
Designer. The diagrams are schematic diagrams.
Template pictures @PCS7Typicals_SENTRON.pdl / @Template_SENTRON.pdl
The icons can be found in the template diagrams @PCS7Typicals_SENTRON.pdl and
@Template_SENTRON.pdl.
When using the "Create/Update Block Icons" function, PCS 7 accesses the file
@PCS7Typicals_SENTRON.pdl .
When manually copying the icons into a process display, you must use the icons from the
@Template_SENTRON.pdl file.
Different variants of block icons
There may be several variants of block icons for one measuring point. These variants are
distinguished by the "type" attribute: The value of this attribute describes the variant. For
example, if you look at a variant of the block icon for a valve, you will find the value
"@Valve/2". You use the part of the value displayed after the "/" to control which variant of
the block icon is produced. You therefore have to enter this part in the object properties for
the block instance. If you do not enter any parameters in the object properties for the block
instance, the standard block icon is produced automatically: This is the block icon with the
"/1" label for the "type" attribute, e.g. "@Valve/1".
Only one version is however supplied per circuit breaker type with the library.
Connection to the measuring point
There is one icon for the driver block that is linked to the associated measuring point using
the "Connect picture block to tag structure" function.
The icons contain the following visible information:
(1) Tag name
(2) Maximum phase current
(3) Group display (EventState)
(4) Circuit breaker in manual (M) / automatic (A)
(5) Circuit breaker state

Description of blocks
3.1 Diagnostics block DIA_WLVL
3.1.1 Calling OBs
The block must be installed in the processing sequence in the following OBs (occurs
automatically in the CFC):
OB1 Cyclic program
OB82 Diagnostic interrupt
OB83 Insert/remove module interrupt
OB85 Program error
OB86 Rack failure
OB100 Warm restart
Installation is performed automatically by means of the function "Generate Module Driver"
3.1.2 Called blocks
The block calls the following blocks:
SFC6 RD_SINFO
SFC51 RDSYSST
3.1.3 Function
The DIA_WLVL block is responsible for diagnosis of the 3WL / 3VL device.
If a 3WL / 3VL is directly connected to the DP master system, the block evaluates the acyclic
events that are relevant for 3WL / 3VL (start-up, DP station failure, module fault), generates
quality code and diagnostic information for the MOD_PAX0 block and provides the driver
block with status information via parameter output OMODE.
In the case of operation following a Y link DPV1, diagnostic information cannot be supplied
to the driver block. The block evaluates start-up, DP station failure and module faults and
provides the driver block with this information via parameter output OMODE.
This block is not used in the case of connection following Y link DPV0.
3.1.4 Message behavior
The block has no message behavior. The messages for DP station failure and module fault
are generated by the MOD_PAX0 block (in the case of direct connection to the DP master
system) or PADP_L00 (in the case of connection following the Y link DPV0) or OB_DIAG1 (in
the case of connection following the Y link DPV1).
Library SENTRON 3WL / 3VL for SIMATIC PCS 7
18 Function Manual, 11/2008, A5E02316914A-01
Description of blocks
3.1 Diagnostics block DIA_WLVL
3.1.5 Error behavior
Failure of the DP master or DP slave has already been determined by the previous
OB_DIAG1 block and evaluated by the RACKF, SUBN1ERR and SUBN2ERR inputs.
In the event of an error, the output OMODE features the identifier for "higher-ranking error"
(OMODE = 16#40xxxxxx).
3.1.6 I/O access error
From the viewpoint of the I/O configuration, 3WL / 3VL is a "compact" DP slave, i.e. it always
has a fixed I/O configuration. It can therefore be assumed that if an I/O access error occurs,
the entire DP slave must have failed (which is reported shortly afterwards).
I/O access errors are not evaluated any further, for this reason.
3.1.7 Module fault
Following a restart and when ACC_ID = TRUE, the module addressed with LADDR is
checked. SZL ID xC91 is read for this purpose. If the module addressed with LADDR does
not exist, the output QMODF is set and the identifier for "higher-ranking error" is entered for
the OMODE output (OMODE=16#40xxxxxx).
3.1.8 Read diagnostics data of 3WL / 3VL
If the 3WL / 3VL outputs a diagnostics alarm, system function RDSYSST (SFC51) will
activate reading of the device-specific diagnostics data.
The device-specific diagnostics data is also read out using the system function RDSYSST
(SFC51) following a CPU restart and rack start-up.
Since 3WL / 3VL following a Y link switches over to DPV0 mode, the device-specific
diagnostics data cannot be read.
The read information is transferred to the MOD_PAX0 block and the driver block where it is
evaluated.
It is also read if a request is output by the driver block at the "DIAG_REQ" input. This occurs
if:
● MAINT_MC ! = 0
● R_MAINT = 1
● Cyclically at DIAREQ_T ! = 0.0 min
The diagnostics data can also be displayed on a Maintenance Station (MS).

SFB52 RDREC
SFB53 WRREC
SFC1 READ_CLK
SFC6 RD_SINFO
SFC20 BLKMOV
SFC21 FILL
3.2.3 Function
The DRV_3WL block is used for measurement acquisition and control and it forms the
interface to the OS.
Automatic / manual mode switch over
Automatic and manual mode are available for operating the driver block. When in manual
mode, the user can control the circuit breaker position (ON / OFF) of the faceplate in WinCC.
When in automatic mode, the corresponding buttons are locked (cannot be operated) in the
faceplate and the circuit breaker is controlled by input parameters which can be connected in
the CFC (AUTO_ON / AUTO_OFF) and therefore by the AS program.
The user can define the mode in which the block is to run in the faceplate or in a block
parameter (AUT_L).
The setting at the LIOP_SEL input determines which of the parameters is currently active.
NOTICE
If an error occurs (monitoring error, Local turn off, Tripped) the block changes to Forced
manual. If the pending error state is acknowledged with one of the RESET buttons, the
block goes into the specified mode again.
If Automatic mode is specified by the AS program (LIOP_SEL = 1, AUT_L = 1) the
commands present at AUTO_ON or AUTO_OFF are always output.
Under certain circumstances this means that resetting error states may cause a switching
operation of the circuit breaker. If this is not desired the user must configure the AS
program accordingly.

Switching the circuit breaker on/off
The user can use the driver block to switch the circuit breaker.
It is important to note here that the ON state means "main contacts closed" and the OFF
state means "main contacts open".
The circuit breaker cannot be switched on or off in certain states:
It must not be switched on when:
• there is a monitoring error
• the block is in maintenance mode
• write protection applies
• the circuit breaker is already on
• the circuit breaker has tripped
• the circuit breaker has been switched off locally
• the circuit breaker is not ready for an On command

(MAINT = 1)
(QWR_PROT = 1)
(QON = 1)
(QTRIP = 1)
(QLOC_OFF = 1)
(RDY_ON = 0)
It must not be switched off when:
• there is a monitoring error
• the block is in maintenance mode
• write protection applies
• the circuit breaker is already off
• the circuit breaker has tripped
• the circuit breaker has been switched off locally
Resetting Tripped and Local turn off states
If the block is in one of the two states, it has to be reset before an On command can be
output again. The faceplate features a corresponding button for the user for this RESET.
CAUTION
Before the circuit breaker is switched back on, the reason for tripping/switching off must be
established and possible error causes must be rectified.
NOTICE
If such a state is reset the response of the mode must be observed as it may cause a
switching operation of the circuit breaker under certain circumstances.

Description of blocks
3.2 Driver module DRV_3WL
Feedback monitoring
When monitoring is activated (MONITOR = On), switching commands (ON / OFF) and the
resetting of trips are time monitored. If the expected state is not reached after an operation
and within the monitoring time (TIME_MON), the block outputs a message and goes into a
resetting state (QMON_ERR).
NOTICE
If the monitoring error is reset the response of the mode must be observed as it may cause
a switching operation of the circuit breaker under certain circumstances.
See Automatic / Manual mode switchover
The faceplate features an appropriate RESET button for resetting this state again.
Measured value acquisition
The block reads measured values from the cyclic process image.
When operating 3WL on the DP master system directly, the block also reads data record 94
with the system function block RDREC (SFB52).
The data record is read in a defined cycle. The interval at which the data record can be read
can be set in seconds using the input parameter CYCLE_T. The default setting is 60
seconds. A cycle of 0 seconds or less means that this data record is not read.
Time synchronization
Data record 68 writes the current time in cycles in order to transfer the current time to the
circuit breaker. This cycle can be set in seconds using the TIME_SYNC_T parameter.
Diagnostics and maintenance
In order to display the current state of the circuit breaker, modules present, statistics
information and diagnostic messages, the module reads the status word from the process
image and data records 91 and 92.
The process image is called in cycles. The user can request the data records in the faceplate
Library SENTRON 3WL / 3VL for SIMATIC PCS 7
Function Manual, 11/2008, A5E02316914A-01
via operations. The diagnostic messages are updated in cycles when messages are present.
WARNING
During maintenance work on the circuit breaker, maintenance mode must be activated!
At the same time, the circuit breaker must be locked locally to prevent it being switched
back on.
Maintenance specifications apply to the circuit breakers (in accordance with EN 50 110-1,
DIN VDE 0105-100 and BGV A2).

3.2.6 Addressing and module driver
The I/O addresses of 3WL must lie completely within the process image of the CPU. In the
CFC chart, the LADDR input is connected to the base address of the 3WL device.
Procedure:
Select input parameter → right mouse button → Interconnection to
address... → Entere.g. EW512
If 3WL is directly connected to the DP master system, the module driver connects block
outputs OMODE, QRACKF and QMODF to inputs MODE00, RACKF and MODF of the block
MOD_PAX0 and the module driver connects input DIAG_INF to output QDIAG_INF of
diagnostics block DIA_WLVL.
In the case of operation following a Y-Link DPV1, the module driver connects block inputs
MODE, RACKF and DIAG_INF to outputs OMODE, QRACKF and QDIAG_INF of
diagnostics block DIA_WLVL.
In the case of operation following a Y-Link DPV0, the module driver connects block inputs
MODE and RACKF to outputs OMODE00 and QRACKF of block PADP_L00.
The block input BASADR is parameterized with the logical base address of the 3WL device
by the module driver.
The block input BASADR_OUT is parameterized with the start address of the outputs of the
3WL device by the module driver.
The input DPA_LINK is parameterized with the connection mode of the 3WL device by the
module driver.
● DPA_LINK = 0 -> Directly connected to the DP master
● DPA_LINK = 1 -> Connected following a DP/PA link
3.2.7 Processing the diagnostics data of the 3WL device
If 3WL is directly connected to the DP master system, the block processes the diagnostic
information that is supplied to it from the DIA_WLVL diagnostics block via the input
DIAG_INF.
The user has the possibility of setting the cycle for cyclic reading of the diagnostics data
record at the "DIAREQ_T" input. At DIAREQ_T = 0.0 minutes no cyclic reading takes place.
