13.2.2
STOP E
Safety Integrated
Safety Integrated allows STOP E to be initiated with a transition into SBH. To achieve this, the
initiation of ESR must be programmed, taking into account system tags
$AC_ESR_TRIGGER=1 and $VA_STOPSI or $VA_STOPESI. The timer can be
parameterized in p9554 "SI Motion transition time from STOP E to SBH" (drive monitoring
channel) and in the MD36954 $MA_SAFE_STOP_SWITCH_TIME_E (NC monitoring channel).
The initiation of STOP E - as a result of a fault - can be realized using PLC-SPL-CDC, FSEND-
FRECV communication or F-I/O fault (Page 390). The acknowledgment or the deselection can
be realized, either using a NC RESET or e.g. in the PLC program using SGE "Deselect ext.
STOP E" in "<axis DB>.DBX32.5".
Safety Integrated plus
Safety Integrated plus only supports STOP E as parameterizable fault response of safety
functions SLS and SLP. All safety functions can be parameterized in dedicated SINUMERIK
Operate screen forms. In the screen forms you can also set the fault response and the delay
time.

Figure 13-1
Selecting STOP E as stop response for SLS
SLS is acknowledged or deselected with STOP E in the safety program of the F-PLC by
resetting the corresponding bits in the drive addresses (via PROFIsafe telegram) - and
additional safety-relevant acknowledgment (PROFIsafe IEACK) along with a PROFIdrive reset.
See also: Acknowledgment (Page 327), Deselecting safety functions integrated in the drive
(Page 233).
For Safety Integrated plus, system tags $VA_STOPSI and $VA_STOPESI are also supplied.
13.2.3
SG override
Safety Integrated
Safety Integrated allows up to 4 safety-relevant velocity values to be used. Safety-relevant
velocities SG2 and SG4 can also be assigned 16 different percentage values, so that 34
different velocity values are available for each axis.
Safety Integrated plus
4 safety-relevant velocity values are also available for Safety Integrated plus. You can set these
4 values in the function-specific SINUMERIK Operate screen form.
In addition, the 1st safety-relevant velocity level can be assigned percentage values between
0 and 100% - to achieve a high level of granularity. To do this, in the associated screen form,
activate option "SLS limit via PROFIsafe for SLS level 1" - and in the safety program, access
the corresponding bit using the PROFIsafe telegram.

13.2 Comparison of the safety functions
This means that theoretically more than a 32,000 values can be defined.
13.2.4
Safe Cams
Safety Integrated
With Safety Integrated, depending on the particular application, you use the "Safe Software
Cams" or "Safe Cam Track" safety function.
● With "Safe software cams", up to 4 cam pairs are available for each axis. Here, the
precondition is that the axes involved are safely referenced.
● Alternatively, the "Safe Cam Track" function can be used, which can be used to evaluate a
total of 30 cams. Here, up to 4 cam tracks - with a maximum of 15 cams per cam track - are
available.
In both cases, you must configure the cams using the appropriate machine data or drive
parameters. SGA with information about the cams can be evaluated using Safe Programmable
Logic (SPL).
Safety Integrated plus
Safety Integrated plus allows safety-relevant cams to be implemented using two different
safety functions:
● Safety function SCA (Safe Cam) allows up to 30 safety-relevant cams per axis to be directly
configured in a function-specific SINUMERIK Operate screen form. To use this safety
function, you require process data S_ZSW_CAM1, which is only available in SIEMENS
telegram 903.
● SP (Safe Position) allows safety-relevant position values to be transferred (process data
S_XIST32) in SIEMENS telegram 902. The safety-relevant position values can be
evaluated in the F-PLC safety program to implement safety-relevant cams.
13.2.5
Parameterizing EMERGENCY STOP
For EMERGENCY STOP shutdowns, for Safety Integrated, the PLC basic program block
"SI_relay [FB10]" was used in conjunction with the corresponding NC SPL syntax for SI relay.
For example, when actuating an EMERGENCY STOP pushbutton, a STOP C or STOP D can
be initiated with delayed STOP A. The same EMERGENCY STOP shutdown operations can
also be implemented when using Safety Integrated plus:

13.2 Comparison of the safety functions
Further, for Safety Integrated, external I/O devices can be shut down in a safety-relevant way
using an SI-relay.
Instead of this function, for Safety Integrated Plus, the certified ESTOP1 operation is available.
Instruction ESTOP1 can be used to control the required stopping requirements in SINAMICS
Safety Integrated as well as the F-I/O.
The following differences exist when parameterizing the switch-off delay time of the
EMERGENCY STOP signal:

Commissioning the F-I/O
Safety Integrated
Initially, you configure and parameterize the F-I/O in STEP 7. You then load the configuration
to the NCU, and also enter some settings in the machine data:
● F-source addresses (PROFIsafe addresses of the F-master)
● F-destination addresses (PROFIsafe addresses of the F-DI-/F-DO modules)
● Allocate symbolic names for F-modules (optional)
● Distribution of the computational load on the NC side
● Select F-user data signals to be transferred in the SPL (F-user data filter)
● Assign F-user data signals to be transferred to the SPL-SGE/SGA
Safety Integrated plus
You configure and parameterize the F-I/O completely in STEP 7 (TIA Portal).

13.3.4
Fault response and acknowledgment for F-I/O faults
Safety Integrated
In the context of Safety Integrated, F-I/O faults are identified by evaluating the PROFIsafe
status of F-I/O devices. A system response is initiated if such a fault occurs:
Error detected by
System response
Drive/NC-CDC
STOP F
SPL-CDC
STOP D/E
(Redundant configuration of the stop response to be initiated in the machine
data and in data block SPL [DB18].)
Communication CDC
The SGE/SGA involved are brought into a failsafe state (substitute values
are provided). Substitute values can be specified.
Additional system-specific responses can be configured by reading out
DB18.DBX119.5.
Generally, the system response can involve passivation of all of the F-I/O modules - or only
those of the channel involved. The cause of the fault must be removed and acknowledged in
order to remove the fault and to reset the system response.
Safety Integrated plus
Safety Integrated plus responds to F-I/O faults by providing substitute values, i.e. passivation is
realized.

13.3 Additional differences when commissioning
The following options exist to adapt and supplement the response:
● Passivate all of the F-I/O modules - or only those of the channel involved.
● Reintegration (depassivation) of the F-I/O automatically, depending on the configuration,
with a user acknowledgment.
● In addition, each F-I/O has its own F-I/O DB. This means that you can access status
information and program user-specific system responses.

For Safety Integrated, the basic PLC program automatically connects the I/O (F-user data) of
an F-module to the SPL interface in data block SPL [DB18]. It is not possible to connect them
in a PLC user program.
The safety functions are accessed on an axis-for-axis basis.
Safety Integrated plus
For Safety Integrated plus, F-I/O and safety-relevant drive telegrams are accessed via the
process image, as is the case for the standard I/O. The PLC user program can access this
status/control information, therefore allowing functional expansions to be made.
Safety functions are accessed on an axis-for-axis basis.

13.4 Procedure when switching over between systems
13.4
Procedure when switching over between systems
It is not possible to automatically migrate the safety functions from Safety Integrated to Safety
Integrated plus.
● The safety-relevant program code used in the two safety modes differs significantly. This
relates to the programming language and operations - as well as the positions and/or blocks
from where the safety program can be called.
● Instead of the safety functions of Safety Integrated integrated in the system, for Safety
Integrated plus, the drive-based safety functions of SINAMICS Safety Integrated are used;
although they are functionally comparable, they use different parameters and values
however.
However, the existing risk analysis and the safety concept can be used to create a new safety
program on this basis - and to configure the drive-integrated safety functions.
Fundamental approach when switching over
The procedure can be roughly split-up into the following steps:
1. Migrating a STEP 7 V5.x project to the TIA Portal
Safety Integrated plus is supported from SINUMERIK STEP 7 toolbox V14 (TIA Portal).
Information about migrating the standard components of a STEP 7 5.x project into the
TIA Portal is provided in the TIA Portal online help, search terms "Migrating SINUMERIK
PLC projects" and "Migrating PLC project".
2. Deleting components of the Safety Integrated (SPL) program from the TIA Portal project:
- Remove the access operations to SPL function blocks or functions - and to SPL data
blocks signals from your PLC user program.
(you can use the following commands to find these locations: "Cross-references" in the
shortcut menu of an SPL block, "Browse project" in the shortcut menu of the program
block folder)
- Delete the Safety Integrated (SPL) blocks used in the project:
SI_relay [FB10]
SI_BrakeTest [FB11]
SPL [DB18]
Additional blocks (e.g. test stop blocks "SI Pulse Teststop SL [FC264]", "SI External Stop
SL [FC265]")

Querying REAL and DOUBLE variables
We recommend programming querying of REAL or DOUBLE variables in NC programs and
synchronized actions as limit value evaluation.
Example: Querying the actual value of an axis $VA_IM to a specific value AXPOS ± 1*10-6
DEF REAL AXPOS = 123.456
IF ($VA_IM[<axis>] - 1ex-6) <= AXPOS <= ($VA_IM[<axis>] + 1ex-6)

$P_TOOLNO
-
INT
Description:
$P_TOOLNO
Active tool number T0 - T32000; T can be an 8-digit number when 'flat D number' function is active
This command should not generally be used when magazine management is active.
When magazine management is active, GETEXET should be used instead.
(T number programming always works reliably when $MC_CUTTING_EDGE_DEFAULT=-1, or> 0.
In cases where $MC_CUTTING_EDGE_DEFAULT=0, or =-2, T number read errors can occur.
The T number mechanism is also reliable if it is programmed after D> 0.
Notice: Particularly with a setting of $MC_CUTTING_EDGE_DEFAULT=-2, $P_TOOLNO (the T no. of the active tool with which the currently
active D offset has been calculated) and GETEXET (the changed tool) can return different T numbers.
->see also $P_MTHSDC and the documentation relating to the subject of multiple toolholders/spindles.

$AC_BLOCKTYPE
Block type
INT
Description:
Variable $AC_BLOCKTYPE determines the type of the current main run block.
The following values are possible:
0: Block is programmed block (main block).
1: Block was generated by the system as an intermediate block.
2: Block was generated by chamfers/rounding
3: Smooth approach and retraction (SAR)
4: Block was generated by tool offset
5: Block was generated by smoothing
6: Block was generated by TLIFT (tangential follow-up)
7: Block was generated by path segmentation
8: Block was generated by compile cycles

$AC_BLOCKTYPEINFO
Block type info
INT
Description:
System variable $AC_BLOCKTYPEINFO can be used to interrogate more
detailed information about variable $AC_BLOCKTYPE.
Depending on the value of system variable $AC_BLOCKTYPE, various values can be
returned:
1. General, internally generated block: $AC_BLOCKTYPE = 1
$AC_BLOCKTYPEINFO = 1000 and contains no further information.
2. Chamfer/rounding: $AC_BLOCKTYPE = 2
2001: Straight
2002: Circle
3. SAR: $AC_BLOCKTYPE = 3
3001: Approach with straight line
3002: Approach with quadrant
3003: Approach with semicircle
4. Tool compensation: $AC_BLOCKTYPE = 4
4001: Approach block after STOPRE
4002: Connection blocks if intersection point not found
4003: Point-type circle on inner corners (with TRACYL only)
4004: Bypass circle (or conical cut) at outer corners
4005: Approach blocks with offset suppression
4006: Approach blocks on repeated WRC activation
4007: Block split due to excessive curvature
4008: Compensation blocks with 3D face milling (tool vector || area vector)
5. Smoothing: $AC_BLOCKTYPE = 5
5001: Smoothing contour by means of G641
5002: Smoothing contour by means of G642
5003: Smoothing contour by means of G643
5004: Smoothing contour by means of G644
6. TLIFT: $AC_BLOCKTYPE = 6
6001: TLIFT block with linear movement of tangential axis and without lift motion.
6002: TLIFT block with nonlinear movement of tangential axis (polynomial)
and without lift movement.
6003: TLIFT block with lift motion, tangential axis motion and lift motion
start simultaneously.
6004: TLIFT block with lift motion, tangential axis starts first if specific lift
position is reached.
7. Path segmentation: $AC_BLOCKTYPE = 7
7001: Programmed path segmentation without active punching/nibbling
7002: Programmed path segmentation with active punching/nibbling
7003: Automatic, internally generated path segmentation
8. Compile cycles: $AC_BLOCKTYPE = 8
In this case, system variable $AC_BLOCKTYPEINFO contains the ID of the compile cycles
Application which created the block
9. Path-relative interpolation of tool orientation (ORIPATH/ORIROTC)
9000: interpolation of tool orientation (ORIPATH)
9001: interpolation of rotation of tool (ORIROTC)
