1.1 SBM Rotary encoder block

hardware address ―GV AD YPI DI―position in increments

alarm- or normal FP ―BO DM QF BO―group error message

encoder type ―I TYP RPI DI―max. increments/revolution

baud rate ―I BDR Y R―normalized speed

resolution ―I EXP U I―revolutions

rated speed ―R RS YF DW―error detection

Brief description

The SBM function block is used to realize the following tasks:

• Initialize the rotary encoder, which is connected at the SBM2 module

• Determine the position and speed from the encoder data

• Error handling when communication errors develop between the

encoder and SBM2 module

Mode of operation

During the initialization phase of the system, the initialization I/O are read
and the appropriate mode set at the SBM2 module. The following
settings are made for the EQN1325 encoder:

• The encoder power supply is set to 5 V

• Number of revolutions to 4096

• Signal periods per revolution 8192

After the mode has been set, the zero position is determined, and the
starting values for the position and the speed output at the connections.

In the standard mode, the block can assume four different statuses:

• NRM
The values read-out from the SBM2 module (position and speed) are
displayed at the block connections. If an error is detected, the block
goes into the ERR error condition.

• ERR
The following errors can occur in operation:

• Encoder is defective or is not connected

• Encoder was disconnected

• Data transfer error for serial communications between the encoder

and SBM2 module

• SBM2 module not available

In the first three cases, the block goes into the "INI“ initialization

status and in the latter case into the "OFF" status.

Configure the block in cyclic tasks or interrupt tasks

DM=0 SBM in interrupt tasks
This mode is only practical in conjunction with the alarm­controlled SIMOLINK events (sync interrupt from SLB). Using this
sync interrupt, in this mode, the values of the SBM module are
de-latched. The block should then be configured in the alarm task
started by the same event.

DM=1 SBM in cyclic tasks
If the block is computed in cyclic tasks, then the SBM2 module
register is read-out in the system mode. The contents of the register
are then read-out in the normal mode and the values for the output
connections computed.

The task of the DPDIAG function block is to provide the following
information and data to the user program (i.e. the configured CFC
software):

• System diagnostics (an overview of which slave had signaled

diagnostics)

Mode of operation

• Data transfer list (overview of with which slave data transfer took

place within the PROFIBUS-DP time frame)

• Master status (master-specification information such as the Stop,

Operate and Clear stati)

The PROFIBUS-DP interface is selected using connection CTS.

The function block only enters a communications error for errors, which
are detected during initialization. A communications error cannot be
acknowledged and this function block is only used for diagnostics. This
means, that in normal operation, a communications error is not entered.
Only the cause of the error is signaled at output YTS.

The DPSLDG function block provides diagnostics data from a DP slave
to the user program. This diagnostics data correspond, with the exception
of the maximum possible length, to EN 50170. According to this
Standard, the diagnostics data can be a maximum of 244 bytes long. The
function block supports a maximum of 240 bytes

Note

Mode of operation

On the EXM448, there are restrictions regarding the quantity of
diagnostics data. Only diagnostics data (Standard diagnostics data) is
supplied which the function block DIAPRO supplies.

The consistency of the outputs is not ensured. When new diagnostics
data is received, some of the outputs can have "New" information and
some can still have "old" information.

The PROFIBUS-DP interface is selected using connection CTS.

The function block only enters a communications error for errors, which
are detected during initialization. A communications error cannot be
acknowledged and the function block DPSLDG is only used for
diagnostics. This means, that in normal operation, a communications
error is not entered. Only the cause of the error is signaled at output

The DPEVT function block (DP event) provides more detailed information
about a Profibus-DP process or diagnostics alarm. The information/data,
provided at the outputs, correspond to the information/data which a
SIMATIC S7 module also has when processing the appropriate alarm
OBs (e.g. OB40, OB55 etc.).

Mode of operation

When an alarm event is output, all of the values at the outputs are
updated.

When the appropriate alarm occurs, the alarm task configured for this
purpose, is started, Within the alarm task, DPEVT reads-out the alarm
information. A new alarm of the same time is only detected again after
the alarm task has been completed.

When a communications error occurs, the cause is also output at output
YTS and the QTS output is set to "0".

@CPB

QTS BO―block status

Brief description

The central block for the P-bus coupling can only run with an FM 458
application module.

• This function block is responsible for initializing and monitoring the P
bus coupling.

• The function block can only be configured once for each application
module FM 458, as there is only one P-bus coupling for each FM 458.
If a function block is configured a multiple number of times, this is
detected when initializing, and results in an entry in the
communications error field.

• The block may only be configured in the sampling interval
32 ms <= TA <= 256 ms. Otherwise, an entry is made in the
communications error field.

Mode of operation

When initializing the function block, general preparations are made to
enable the coupling. The coupling is only enabled after the standard
mode has been run-through (executed) several times.

After the coupling has been enabled, the central block monitors that
senders and receivers are correctly registered. Further, if required, it re­organizes and updates the block output CDM at each processing cycle.

The function block cannot be used to initialize another P-bus coupling or
monitor this. It can only initialize its own P-bus coupling on which CPU is
configured. An entry is made in the communications error field if another
module name is specified at the CTS input (other than its own).

The CDM block output provides information about the coupling status.
The connection is a 1, if the coupling is enabled for general send/receive
operation. The CDM block output is 0, as long as the coupling is still
being initialized, or is being re-initialized (after a temporary fault).

S7RD_P

Enable ―BO EN YF W―StatusInfo Block

This block can only be used for the SIMATIC application module FM 458­1 DP.
A SIMATIC-CPU can transfer up to 128 bytes to the FM 458-1 DP in its
output area of the P bus. Block S7RD_P reads this data from the P-Bus
and provides it, via its pointer interface, to the read blocks (DRD…,
CPY_Y) for further processing in the CFC configured software.

This block operates similar to the telegram block CRV_P. A maximum of
128 bytes can be accessed via the pointer interface. These bytes are
sent from the SIMATIC-CPU to the FM 458-1 DP via the P bus.
Data can be read using the read blocks (DRD…) or the copy block
(CPY_P).

This block only communicates with a SIMATIC-CPU. This means that the
required byte or word swap operations are automatically made
(depending on the data type of the connected read/write blocks). The
entry, which is normally required at the SW-connection of the read/write
block, is not evaluated and is therefore not required.

S7WR_P

This block can only be used for the SIMATIC application module FM 458­1 DP.
An FM 458-1 DP can send up to 128 bytes to the SIMATIC-CPU via the
P-Bus. The block S7WR_P sends data which were previously loaded
with write blocks via the pointer interface.

This block operates similar to the telegram block CTV_P. A maximum of
128 bytes can be transferred via this pointer interface and via the P bus
to the SIMATIC CPU. This data is previously loaded into the telegram
buffer using write blocks DWR… of the copy block CPY_Y.

This block only communicates with a SIMATIC-CPU. This means that the
required byte or word swap operations are automatically made
(depending on the data type of the connected read/write blocks). The

Brief description

The function block allows block-oriented data reception via a configured

Mode of operation

The BRCV block receives data from a "remote" partner. The "remote"
partner is an SFB/FB, type BSEND (SFB/FB 12) on a SIMATIC S7-400
CPU.

After each data segment which has been received, an acknowledgement
is sent to the partner SFB/FB and the LEN parameter is updated.

The block is ready to receive when a "1" is connected to the control input
ENR. A running task can be interrupted with ENR=0.

The maximum length of the receive area is specified by the data at input
RLN. The length of the data block received is displayed at output LEN.

I/O

ENR Control parameter

The block is ready to receive with ENR = 1

ID Addressing parameter

Reference to the local connection description
(this is specified as a result of the STEP7 configured connection)

RID The value at input RID specifies the association with the send SFB/FB.

The value at the input must match the R_ID parameter for SFB/FB on
the
send side. This allows several SFB/FB pairs to communicate via the
same logical coupling. The block pairs of a logical coupling, defined
using
RID or R_ID must be unique for this coupling.

RLN The maximum length of the received data is defined here.

Only values of between 0 and 65535 may be configured.

Brief description

The function blocks, read from the peripheral area of the S7-CPU, can
only run with an FM 458 application module.

The S7RD, S7RD_B, S7RD_I, S7RD_D blocks only differ by the data
type at the output, which must correspond with the parameters to be
read:

• S7RD: REAL

• S7RD_B: BOOL

• S7RD_I: INT

• S7RD_D: DINT

Mode of operation

With this block, data can be read into the assigned net data area of the
SIMATIC S7-CPU, (periphery output) assigned to the FM 458 application
module. This PE area is 128 bytes.

If the enable signal is set, the appropriate value is read from the PA area
and made available at output Y.

The offset determines at which location in the PA area, the value is
retrieved.

Depending on the block- or data type, the offset is specified as follows:

• for REAL data type in 4-byte steps (data length)
value range of the offset: 0 . . . 31

• for BOOL data type in 1-byte steps (data length).
value range of the offset: 0 . . . 127

• for INT data type in 2-byte steps (data length).
value range of the offset: 0 . . . 63

• for DINT data type in 4-byte steps (data length).

@FMPAR

Brief description

The FB @FMPAR can only be configured on a FM 458-1 DP module.

FB @FMPAR monitors the COMBOARD (communications submodule of
the SIMOVERT MASTER DRIVES, e.g. CBP for PROFIBUS DP) and
processes the parameter tasks which are defined for it.

Several @FMPAR central blocks for various COMBOARDs can be
configured on a FM 458-1 DP module.

It should be configured in a slow sampling time (approx. 100 ms). The
maximum permissible sampling time is 200 ms (as a result of the
monitoring using adjacent modules).

The existence and correction functioning of the COMBOARD is
automatically identified and is displayed at output CS.

Mode of operation

Only one COMBOARD may be configured using FB @FMPAR.

Parameter processing:

Parameters are configured in the comment at each I/O. If the comment
starts with "@TP_", then this I/O is designated as parameter. Every
parameter can be allocated a parameter name (FB-PNAME). Further, a
setting parameter can also be allocated a minimum and a maximum (FB­PLIM).

The block handles the following tasks:

• Checks the module code of the COMBOARD

• Monitors the COMBOARD (lifebit counter)

• Transfers the configuration data to the COMBOARD

• Processes the parameter channels

• In standard operation, processes the parameter tasks (in the

sampling time cycle).

Function Blocks - FM 458-1 DP 2-29
Edition 12.2004

Communication blocks

The name of the COMBOARD which is to be processed, is configured at
input CTS of the FB @FMPAR. If a name has not be configured at input
CTS, then the FB @FMPAR shuts itself down with an error signal at
output YT1/2.

NOTE

Function blocks CRV and CTV may only be configured once. They can
be configured on any and on different processor modules. However,
parameter processing is possible for all processor modules.

A REAL type quantity is saved in the NOV-RAM of a technology module.

The function block is a read/write memory for a REAL value. It is only
active, if a 0 at output QF indicates that the memory space in the
NOVRAM is available. The function block operating mode is selected at
input M:

• The quantity to be saved is entered at input X. It is transferred to
output Y.

• Further, input quantity X is entered in the NOV-RAM of the module. In
this case, a value, already contained in the NOV-RAM is overwritten.

• The last input quantity, saved in the write operating mode, is output
at Y.

• The NOV-RAM is deleted from the operating system each time the
configured software changes (even when the system is configured for
the first time), i.e. zeros are written into it. If the NOV-RAM is then
read, without having previously written a value into the NOV RAM,
then the initialization value of the NOV RAM (zero) is output at Y.

In the INIT operating mode of the function block, memory is made
available to accept a REAL value. Output QF is set to 1 if this is not (no
longer) possible. The function block is then inactive in the RUN operating
mode.

Brief description

Mode of operation

NOTE

This function block, which initiates a process interrupt to the SIMATIC
S7-CPU, can only run with an FM 458-1 DP application module.

The function block initiates a process interrupt at the associated S7 CPU.

The IFO double word is transferred to the S7-CPU as supplementary
interrupt information.

A process interrupt is only acknowledged after the process interrupt
OBs (organization block) has been executed on the S7-CPU.
The block does not wait for the acknowledgment. The OB is
parameterized in the HWConfig for the associated S7-CPU.

The process interrupt is only initiated, if the S7-CPU is not processing a
process interrupt from the FM 458-1 DP application module.

Output QF has the value 1, if a new process interrupt is initiated,
although the last process interrupt was still not acknowledged or the
block was not configured on FM 458-1 DP.

Output QF has the value 0, if the acknowledgment from the S7-CPU has
been received, or if input RES has the value 1.

The interrupt is initiated as a function of the input TMB:

• for TMB = 0, if a signal changes from 0 to 1 at input I, or.

• for TMB = 1, if any signal transition occurs at input I.

Brief description

The @SL central block allows the initialization and monitoring of
communications with an SLB module.

An SLB module is a system hardware component, which can be an ITSL­, an EXM 448-1 module or an optional SLB (SIMOLINK Board) of the
ITSL module.

The @SL central block may only be configured in a cyclic task and once
per SIMOLINK ring.

The following parameters must be set for an SLB module:

• Hardware address SLB (TAD)

• Operating mode (MOD)

• Node address (ASL), only relevant when operating mode 0 is selected

• Send power (POW) for the SLB module

Mode of operation

1. The @SL central block executes the following steps while the system
is being initialized:

− Checks the validity of the value ranges at the input connections

− Checks whether additional @SL central blocks have been

configured at the same hardware address (input TAD)

− Initializes the SLB module corresponding to the data at the

initialization connections

Function Blocks - FM 458-1 DP 5-1
Edition 12.2004

SIMOLINK drive coupling

− Sends an initialization sequence (SIMOLINK) and monitors the
starting sequence

2. The @SL central block executes, in the standard mode ("RUN“
operating status) of the system, the following operating steps:

− Monitors communications of the SIMOLINK drive interface

− Outputs fault messages when communication faults occur at the

outputs

− Outputs information about the drive coupling

− New values for the node address (ASL) and send power (POW)

are only transferred after the SIMOLINK drive coupling restarts.

Operating mode

0 Slave mode

The SLB module operates as slave. The SIMOLINK blocks in the CFC chart must be configured
in an interrupt task Ix (x=1 . . . 8).

Timing: an interrupt is initiated each time a SYNC telegram is received, and therefore starts
execution of interrupt task Ix. The received values are read and the values to be sent are written
into the write buffer of the SLB module.

Processing time of the

SIMOLINK blocks

1 Asynchronous mode

The SLB module operates as master. The SIMOLINK blocks in the CFC chart must be
configured in a cyclic task Tx (x=1 . . . 5).

Timing: The blocks are executed each time cyclic task Tx starts. The SIMOLINK telegrams are
sent after the last SIMOLINK block has been calculated.

Processing time of the
SIMOLINK blocks

An SLB module can be initialized and can operate in 6 different operating
modes.

When configuring, the different time characteristics of the SIMOLINK

The SLB module operates as master. The SIMOLINK blocks in the CFC chart must be
configured in an interrupt task Ix (x=1 . . . 8).

Timing: A timer of the ITSL/EXM 448-1 module initiates, corresponding to the equivalent
sampling time, an interrupt, and therefore execution of interrupt task Ix. The SIMOLINK
telegrams are sent after the last SIMOLINK block has been calculated.

The SLB module operates as master. The SIMOLINK blocks in the CFC chart must be

Timing: Each SYNC telegram which is received, initiates an interrupt, and therefore execution of
the interrupt task Ix. The SIMOLINK bus cycle is automatically re-initiated each time a SYNC
telegram is received. SIMOLINK telegrams are sent and received in parallel with the signal
processing (internal calculations).

The SLB module operates as master. The SIMOLINK blocks in the CFC chart must be

Timing: The bask clock cycle T0 from the system initiates that telegrams are sent, and therefore
the start of the SIMOLINK cycle. A subsequently received SYNC telegram initiates an interrupt
and therefore execution of interrupt task Ix. The signal processing (internal calculations) are
realized after the SIMOLINK telegram has been sent and received.

Timing: The basic clock cycle T0 initiates that telegrams are sent (starts the SIMOLINK cycle)
and the SIMOLINK blocks are processed in T1=T0. The signals are processed (internal
calculation) at the same time as sending and receiving SIMOLINK telegrams.

Brief description

2 setpoints can be sent to each slave using the SLSV2 send block. In this
case, the block can handle a maximum of 8 slaves. The first setpoint is
transferred to all of the 8 slaves.

This functionality can be used to implement a virtual shaft, especially if
the time and the position/angular setpoint must be transferred to the
slaves.

Mode of operation

The SLSV2 and SLSV2R function blocks are functionally identical. The
only difference is the data type of the setpoint connections XO0 to XO7:
SLSV2: DINT
SLSV2R: REAL

1. The SLSV2 send block executes the following steps while the system
is being initialized:

− Checks the task assignment

− Initializes the task list of the SLB module corresponding to the data

configured at the inputs

2. In the normal system mode ("RUN" mode), the SLSV2 send block
executes the following steps:

− Calculates the setpoints

− Checks that the inputs are within the permissible value ranges

− Enters the setpoints to be sent into the write buffer of the SLB

module

• Checks that the inputs are within the permissible value range

• Enters the setpoints to be sent into the write buffer of the SLB

module

• Reads-out the actual values to be received from the receive
buffer of the SLB module

Brief description

the virtual master block INT_M is used to generate position reference
values in angular synchronism.

Mode of operation

The block sums the input values X, weighted with ratio NM and DN.

If the sum of the modulo value MOD exceeds or falls below 0, the modulo
value is subtracted or added, and an overflow bit QP or QN is set for the
duration of the sampling time.
