3.1 General points about Sercos III

Please Note

The bus node CPX-FB39 is a remote I/O system that communicates with the Sercos controller via the Sercos IO profile (Function Specific Profile IO).

Sercos III is an Ethernet-based communication protocol for automation applications. Communication on a Sercos III network is based on the time-stop process with cyclical data transmis sion in the form of telegrams based on the master-slave principle. This combines real-time and nonreal-time communication channels in a communication system.

Real Time Channel (RTC)

During transmission in real-time, a distinction is made between two types of telegram. – Master data telegram (MDT): For communication of nominal/setpoint data from master to slaves. – Acknowledge telegram (AT): For communication of status data from slaves to master and for trans

verse communication between the individual controllers or slaves.

Non-real-time channel (Universal Communication Channel - UCC)

For the exchange of standard Ethernet telegrams between any participants on the network.

You will find further information about Sercos III on the Internet: è www.sercos.org

3.2 Depiction of the CPX system on the Sercos-device model

The underlying depiction of the CPX system on Sercos is illustrated by the next graphic (è Fig. 3.1). The CPX system is illustrated here as a Sercos device with a Sercos interface, a Sercos slave and the associated sub device. Communication is performed by the Sercos interface and the Sercos slave. Gen eric parts of the device application are implemented as part of the sub device. The resource IO is as signed to the sub device: It depicts the Sercos function profile (Function Specific Profile IO) and in cludes a depiction of the individual CPX modules on Sercos.

3.3 Device description

During initial commissioning of a Sercos participant, the controller software is notified of certain prop erties of the participant. These properties are administered in what are known as device description files in standardized XML format. The device description of Sercos-III devices is in the form of SDDML files (Sercos Device Description Markup Language) and is based on the Sercos-III device model. This provides a separate device de scription file for each device.

The device description files (SDDML files) are available on the Festo support portal on the Internet (è www.festo.com/sp).

3.4 Address assignment

A CPX terminal consists of a different number of inputs and outputs, depending on your order and the configuration of the bus node. The inputs and outputs are assigned automatically within the CPX terminal.

When using device description files (SDDML files) the controller software can extrapolate the complete address assignment automatically.

Warning

Uncontrolled movement of the actuators, undefined switching statuses. Injury to people, damage to the machine and system. The byte sequence of the process data is Little Endian.  Ensure that the process data is interpreted correctly.

Please Note

– Including bus nodes, a maximum of 10 electrical modules plus a pneumatic interface

and/or MPA pneumatic module is permitted in a CPX terminal.

– The address space of a CPX terminal is limited. The bus node provides the CPX ter

minal a maximum address space of 64 bytes for inputs and 64 bytes for outputs. – An activated diagnostic mode reduces the number of available I/O bytes. – Each module of the CPX terminal occupies a specific number of bits, bytes or words

for module communication.

 Establish the address assignment (number of allocated inputs/outputs) on the CPX terminal prior to

commissioning.

Tab. 3.8 serves to determine the address assignment and/or the number of assigned inputs and outputs on the CPX terminals. The number of assigned inputs and outputs for modules can be found in the following tables: – Bus node CPX-FB39:

– FG S-0-1500.SI.0 – Bus Coupler (è Tab. 3.1)

3.5 Addressing

3.5.1 Basic rules for addressing

– The address assignment of the inputs does not depend on the address assignment of the outputs. – Counting is byte-wise from left to right, in ascending order without gaps.

Even modules with less than 8 bits occupy 8 bits of address space, but do not use all this space.

– The bus node counts as a module with 0 inputs and 0 outputs when the status bits and the I/O dia

gnostic interface are deactivated.

Please Note

Address assignment with activated status bits or activated I/O diagnostics interface. – If the 8 status bits are activated, these occupy the first 16 inputs in the address

range, although only 8 inputs are used.

– If the I/O diagnostics interface is activated, it will occupy the first 16 inputs and

outputs in the address range.

– The inputs and outputs of various different types of module are assigned separately from one an

other, and the sequence depends on the arrangement of modules in the CPX terminal. – Input data: S-0-1500.SI.9 (Container Input Data) – Output data: S-0-1500.SI.5 (Container Output Data).

Please Note

In the Remote I/O operating mode, the bus node must be placed as the first module (slot 0) to the far left of the CPX terminal.

3.5.5 Address assignment after extension/conversion

If the requirements for the machine or system change, the CPX terminal can be adapted as required due to its modular design.

Caution

If the CPX terminal is extended or converted at a later stage, input/output addresses may be shifted. This applies in the following cases: – Additional modules are inserted between existing modules. – Existing modules are removed or replaced by other modules which have fewer or

more input/output addresses.

– Interlinking blocks or pneumatic connection blocks for monostable valves are re

placed by interlinking blocks/connection blocks for bistable valves or vice versa

(è Pneumatics description). – Additional interlinking blocks or connection blocks are inserted between existing ones. – Status bits or the I/O diagnostic interface are activated/deactivated. – The configured addresses of the pneumatic interface are modified.

Please Note

If the configuration of a CPX terminal was changed, new requirements for the CPX ter minal that may be necessary must be checked and adjusted, if necessary.

Moreover, it should be noted that the needed address space may increase due to modific ation of the CPX terminal and thus the slave addresses of the following slaves in the net work must be checked and adjusted if necessary.

3.7 Parameterisation

3.7.1 Introduction to parameterisation

The CPX terminal is supplied with factory-preset parameters (default parameterisation). The system characteristics of a CPX terminal and of individual modules and channels can be parameter ized individually. A distinction is made here between the following parameters:

Parameter Description Examples

System parameters Global system functions for the

complete CPX terminal

Module parameters Module and channel-specific functions

of the respective module Diagnostic memory parameters

Tab. 3.9

Operating method of the diagnostic

memory

A detailed description of the individual parameters as well as basic principles of applica tion can be found in the CPX system description (è P.BE-CPX-SYS-...). Which parameters stand for the modules used are found in the description for the re spective module.

Caution

If the Modify-LED (M) lights up permanently, the parameterisation is not stored locally in the bus node and is not restored automatically by the higher-order system upon re placement.  In these cases, check before replacement to see which settings are required and

carry out these settings. Changes in parameterisation or application-specific parameter settings result in changes to the module or system behaviour.  Check especially when replacing CPX terminals to see which settings are necessary

and make sure that these are restored, if necessary (e.g. by appropriate system-

start parameterisation).

– Short-circuit monitoring – System start – Input debounce time – Signal extension time – Remaining entries with Power ON – Error number filter

Warning

The connected actuators can move unexpectedly! Modification of the signal statuses and parameters can trigger dangerous movements of the connected actuator technology.  Make sure that nobody is in the positioning range of connected actuators, and be

very careful with the parameterisation or manipulation of signal statuses.  Always note the instructions relating to “Force”, “Idle Mode”and “Fail Safe”in the

CPX system description (è P.BE-CPX-SYS-…), in the description for the CPX-MMI

(è P.BE-CPX-MMI-1-…) and in the online help for the CPX-FMT.

3.7.2 Prerequisite for parameterization

Please Note

A CPX terminal can be parameterised only if the function “System start with default parameterisation and current CPX expansion” is activated.  Set the system parameter “System start”accordingly.

With the system parameter “System start”, you can define the starting characteristics of the CPX ter minal. Factory settings are used unless parameterization is altered.  Select the setting “System start with default parameterization and current CPX expansion”to permit

the required parameterization.

 To conduct the parameterization, use the Festo Maintenance Tool (CPX-FMT) software or the control

device (CPX-MMI).

 After parameterization, change the setting of the system parameter “System start”to “System start

with stored parameterization and stored CPX expansion”to define the settings and to save them in

the module. After a reboot of the CPX terminal, the Modify-LED (M) lights up continuously on the bus node. The terminal uses the saved parameter settings.

Caution

If the Modify-LED (M) is lit continuously, the parameterization during replacement is not set up automatically by the higher-level controller.  In such cases, examine before replacement which settings are required and imple

ment them.

3.7.3 Methods of parameterisation

A CPX terminal with the bus node CPX-FB39 can be parameterised with various methods.

Method Benefits Disadvantages

Festo Maintenance Tool (CPX-FMT) Menu-guided parameter entries via PC software Operator unit (CPX-MMI) Menu-guided parameter entry

out via the control system.

The controller must support the configuration via SDDML files.

3.7.4 Parameterisation via the Festo Maintenance Tool (CPX-FMT) software

With the Festo Maintenance Tool (CPX-FMT) software, a CPX terminal can be parameterized via a USB or Ethernet connection.

Please Note

To run the software on the bus node via a USB connection, you need a USB connector cable and the USB adapter NEFC-M12G5-0.3-U1G5.

The current version of the Festo Maintenance Tool (CPX-FMT) software is available for download in the Festo Support Portal (è www.festo.com/sp).

3.7.5 Parameterization with the control device (CPX-MMI)

With the operator unit (CPX-MMI), a CPX terminal can be parameterised through a menu even without controller software.

Information on general operation of the operator unit can be found in the corresponding description (è P.BE-CPX-MMI-1-…).

Please Note

The last parameterisation set or received in the CPX terminal is always valid.

3.7.6 Parameterization via Sercos III

The bus node can be parameterized directly by the controller via Sercos III.

This has the advantage that all parameters are saved in the controller software and auto matically transferred to the bus node at run-up of the controller. As a result, parameterisation remains intact if the bus node is replaced.

4 Diagnostics and error handling

4.3 Diagnostics via status bits

Status bits are internal inputs that serve to display common diagnostic messages (global error mes sages).

Please Note

The diagnostic mode “Status bits” must be activated via DIL switch 2.2 on the bus node (è 2.4.5 Setting of the diagnostic mode (remote I/O)).

Status bits are treated as inputs and there can be queried, linked and processed as “standard” inputs.

In the case of activated “Status bits” diagnostics mode, the first 16 inputs are assigned although only 8 inputs are used (è 3.5.1 Basic rules for addressing).

Status bits are treated as “normal” inputs. – If all status bits supply a 0-signal, no error is reported. – If at least one status bit delivers a 1-signal, there is a fault. The diagnostic information when there is

a 1-signal is shown in the following table.

Bit Diagnostic information with a 1-signal Description

0 Fault at valve or pneumatic module Module type in which an error has occurred 1 Error on output module 2 Error on input module 3 Error on analogue module or technology module 4 Undervoltage Error type 5 Short circuit/overload 6 Wire break 7 Other error

Tab. 4.2

Please Note

If various errors occur simultaneously on different types of modules, these errors can not be assigned via the status bits. Errors can be uniquely defined via the I/O diagnostics interface, if needed.

Further notes on the function and content of the status bits are found in the CPX system description (è P.BE-CPX-SYS-…).

Festo – P.BE-CPX-FB39-EN – 1504NH – English 59

4 Diagnostics and error handling

4.4 Diagnostics via the I/O diagnostics interface

Detailed diagnostic information on the CPX terminal can be accessed via the “I/O diagnostics interface” diagnostics mode. You can ascertain this exactly, e.g. by noting on which module and channel an error has occurred. To call up this information, 16 input bits and 16 output bits enable all diagnostic informa tion to be read out.

Please Note

To use the “I/O diagnostic interface” diagnostics mode, it must be activated via DIL switch 2 on the bus node (è 2.4.5 Setting of the diagnostic mode (remote I/O)).

If the “I/O diagnostic interface” is activated, it will occupy the first 16 inputs and outputs in the address range (è 3.5.1 Basic rules for addressing).

The following table provides an overview of the available diagnostic information.

Diagnostic information Description

Global diagnostic data – General overview of errors Diagnostic data module – Detailed diagnostics per module Diagnostic data status – Number of entries in the diagnostic memory

4 Diagnostics and error handling

4.6 Error handling

With the following malfunctions, the behaviour of the CPX terminal depends on the configured beha viour of the master module and the parameterised fail-safe setting: – Telegram failure – stop of the master – interruption in the bus cable.

Depending upon the configuration, the outputs (valves and electrical outputs) are switched off (factory setting), switched on or they retain their existing status. Further information can be found in the CPX system description (è P.BE-CPX-SYS-…).

These characteristics can be altered using the Festo Maintenance Tool (CPX-FMT) software, the control device (CPX-MMI) or Sercos mechanisms.

Change via Sercos

 Change configuration of fallback values (è Tab. B.12 (IO_FG.SI.22 - Fallback Value Output)).  Change configuration of fallback values (è Tab. B.12 (IO_FG.SI.02 - Configuration Of IO_FG).

Change via CPX-FMT/CPX-MMI

 Change configuration of failsafe values (è CPX system description P.BE-CPX-SYS-…, online help

with CPX-FMT software or description of control device P.BE-CPX-MMI-1-…).

Please Note

A change in the fallback and backup values via Sercos also has a corresponding impact on the failsafe entries in the CPX system table (è Tab. B.14). In the event of any retrospective adjustment of fallback values via CPX-FMT or CPX-MMI, the backup value characteristics provided for in the Sercos standard no longer apply.

Warning

Accidental activation of actuators! An incorrect status of the valves and outputs can lead to dangerous situations!  Ensure that valves and outputs relating to the aforementioned problems are placed

in a safe condition.

Please Note

If the outputs are reset in conjunction with PLC-Stop, field bus interruption or a fault, pay attention to the following: – monostable valves move to the initial position. – Double solenoid valves remain in the current position. – Mid-position valves go into mid-position (pressurized, exhausted or closed, depend

ing on valve type).

Designation Explanation

This IDN is implemented as an 8-byte value. Byte 0: Status bits (error type and source of error) Byte 1: Module number and diagnostic status

Byte 2: Error number S-0-1500.SI.151 IO_FG.SI.151

IO function group is assigned.

1) 2)

Byte 0: Number of the first defective channel

Byte 1: Module error number

Byte 2: Info 2 (reserved)

Byte 3: Info 3 (reserved) S-0-1500.SI.152 IO_FG.SI.152

Channel Diagnostics Diagnostic data of all channels of the CPX module

to which the IO function group is assigned.

1) 3)

The content of the IDN is the fault number of the

corresponding channel. S-0-1500.SI.200 CPX system parameters Global system parameters of the CPX system

This IDN is implemented as a byte list with a

length of 8.

1) This IDN only permits read access.

2) All sessions of this IDN are implemented as a 4-byte value. One session corresponds to one CPX module.

3) All sessions of this IDN are implemented as a 1-byte list. The length of the list is computed from the total of I channels and O

channels for the corresponding IO function group.

4) Due to the fact that the behaviour of the outputs in the event of a fault with Sercos is specified by parameters IO_FG.SI.02 and

IO_FG.SI.22, the system parameter “Behaviour in response to a Fail State” is factory set to “Fault Mode”.

By setting this parameter to 00 (All Outputs Reset) or 01 (Hold Last State), the specific substitute value characteristics of Sercos

are disabled. The system parameter “Behaviour in an Idle Mode fail state” is not used.

B.4 Overview of the supported classes

B.4.1 Supported classes of the Sercos Communication Profile (SCP)

Class Description

SCP_VarCFG This class is needed to initialize the cyclical exchange of data between

master and slave. A slave that implements the class SCP_VarCFG provides the following functions: – Accesses via the service channel are completely supported – Cyclical transmission of “Device Control” and “Device Status” – The slave defines which data can be transmitted cyclically and how

many connections are possible. The slave provides the master with these data to enable the master to initialize all connections correctly.

SCP_WDCon A slave that implements the class SCP_WDCon provides a watchdog

function that enables connections to be monitored and, in the event of connection terminations, to initiate corresponding fault responses.

SCP_Diag A slave that implements class SCP_Diag provides information that helps to

run bus diagnostics.

SCP_NRTPC A slave that implements class SCP_NRTPC enables the UCC (Universal

Communication Channel) to be used for the transmission of non-Sercos-Ethernet telegrams.

SCP_Cyc A slave that implements the class SCP_Cyc provides all of the functions

needed to transmit and to receive cyclical data (produce and consume).

Tab. B.15

B.4.2 Supported classes of the Generic Device Profile (GDP)

Class Description

GDP_Basic Contains all the essential IDNs needed for a Sercos device. GDP_DiagT Basic function of the Sercos Diagnostic Trace. GDP_DiagTAdv Extended functions of the Sercos Diagnostic Trace. GDP_Id Contains IDNs with information for the identification of a device or module. GDP_Rev Contains IDNs with information for overhauling (hardware and firmware) of

the bus node.
