6 2 Function 2 Function 2.1 General remarks The product is intended for the operation of system CPX-E in an EtherCAT network. Data is transmitted on the basis of Industrial Ethernet following the IEEE protocol. The product has two Ethernet interfaces (RJ45) and support any topologies. The EtherCAT address (0 4095) can be set manually using DIL switches, which means that the Hot Connect function (for coupling and decoupling devices during operation) can be used Web server The integrated web server provides read access to the key parameters and diagnostic functions of system CPX-E. The web server can be reached through the Ethernet over EtherCAT (EoE) protocol and must be configured accordingly in the controller. The IP address and subnet mask must be assigned individually. To access the web server, the following settings must be made: IP address on PC (e.g ) IP address on the higher-order controller for the connection to the PC (e.g ) IP address and subnet mask on the higher-order controller for the connection to the bus module (e.g ; ). Activation of Ethernet over EtherCAT (EoE) and IP Routing on the higher-order controller An IP address and subnet mask must be assigned to the bus module (e.g ; ) The subnet mask of the bus module must correspond with the subnet mask for the connection to the bus module on the higher-order controller. In the Windows program cmd.exe, the following routing setting must be entered: route add mask Device description file The project planning for the bus module in the controller software of the higher-order controller is implemented by a device description file (ESI file). This contains all the information required to parameterise system CPX-E via controller software (e.g. Beckhoff TwinCAT). The device description file is available on the Festo Support Portal Crossover detection (auto MDI/MDI-X) The product supports crossover detection (auto MDI/MDI-X), so both patch cables and crossover cables can optionally be used. When using patch cables and crossover cables in the same network, crossover detection must be activated in the higher-order controller Distributed Clocks The product supports the Distributed Clocks for the precise synchronisation of participants in an EtherCAT network. Applications can therefore be implemented that required simultaneously coordinated actions. The following CPX-E modules allow synchronized operation when Distributed Clocks is used: Digital input module CPX-E-16DI(-P) Digital output module CPX-E-8DO(-P) Counter module CPX-E-1CI 6 Festo CPX-E-EC-EN English

8 2 Function Control components Rotary/DIL Function switches Using the 3 rotary switch, EtherCAT Explicit Device ID of the bus module is set with hexadecimal coding. Possible settings: 0 = saved EtherCAT address, no Explicit Device ID assigned (1 h fff h ) = permissible address range In case of a setting of 0, the address of the bus module is automatically assigned by the EtherCAT master (auto increment).

10 2 Function 2.2 Address assignment The system CPX-E is composed of a different number of inputs and outputs, depending on the number and type of modules CPX-E used and the parameterisation of the bus module. The inputs and outputs are assigned automatically within the system CPX-E. The address assignment (number of allocated inputs and outputs) on the system CPX-E must be determined prior to commissioning. A maximum of 10 I/O modules + bus module is permitted in one system CPX-E. The address space of a system CPX-E is limited. The bus module provides the system CPX-E with a maximum address space of 64 bytes for inputs and 64 bytes for outputs. Activated diagnostic functions as well as status bits or the I/O diagnostic interface reduce the size of the available address space. 2.3 Addressing Basic rules for addressing The address assignment of the inputs does not depend on the address assignment of the outputs. The numbering goes from left to right. The bus module counts as a module with 0 inputs and 0 outputs when the status bits and the I/O diagnostic interface are deactivated. Activated status bits occupy 16 inputs (only 8 inputs are used). An activated I/O diagnostic interface occupies 16 inputs and 16 outputs. The inputs and outputs of different module types are assigned separately from each other. The I/O addresses are assigned in ascending order according to the module number Addressing example 1 Bus module CPX-E-EC (with status bits) Status bits activated I/O diagnostic interface deactivated 2 Digital input module CPX-E-16DI 3 Digital output module CPX-E-8DO 4 Digital output module CPX-E-8DO 5 Analogue input module CPX-E-4AI-U-I 6 Analogue output module CPX-E-4AO-U-I Module no.: Fig The address assignment for the system CPX-E presented is shown in Tab Module no.

14 2 Function Status bits System CPX-E provides 8 status bits for displaying global common diagnostic messages. The status bits are configured like inputs and supply coded diagnostic information in the form of 0 or 1 signals. If all status bits are supplying a 0 signal, there is no error. If, in contrast, a status bit supplies a 1 signal, there is a fault. In order to make use of the status bits function, the bus module of the system CPX-E must be configured accordingly. If different errors occur simultaneously on different types of modules, errors cannot be distinguished. The I/O diagnostic interface can be used to distinguish errors clearly I/O diagnostic interface. You can find detailed information about status bits in the Description of system CPX-E 1.1 Further applicable documents I/O diagnostic interface The system CPX-E provides an I/O diagnostic interface in the form of 16 input bits and 16 output bits for reading detailed diagnostic information. The I/O diagnostic interface can be used, for example, to precisely determine the module and channel on which an error has occurred. In order to make use of the I/O diagnostic interface, the bus module of the system CPX-E must be configured accordingly. You can find detailed information about the I/O diagnostics interface in the Description of system CPX-E 1.1 Further applicable documents. 14 Festo CPX-E-EC-EN English

15 2 Function 2.5 Diagnostics via EtherCAT The availability of diagnostic information depends on the settings of the DIL switch and parameterisation. To guarantee that error messages of system CPX-E are automatically displayed in the controller software, the I/O diagnostic interface must be activated Diagnostics via SDO access Diagnostic information can be requested from the higher-order controller through SDO access. The corresponding objects are listed in the appendix 3.1 Object directory (Modular Device Profile) Diagnostics via diagnostics history The last 63 diagnostic messages of the bus module can be displayed via diagnostic object 0x10F3. An error message referenced with a code is displayed for every event (warning, error, information). The diagnostic messages are translated using the ESI file and can be read from the controller software in this way.

Acknowledge mode: A diagnostic message must first be acknowledged before it can be overwritten with a new diagnostic message. When the number of unacknowledged diagnostic messages reaches 64, new diagnostic messages will not be saved and will be lost.

Operating mode Value of bit 4 Overwrite mode 0 Acknowledge mode 1 Tab Mapping of New message available message For the simplification of the diagnostic evaluation, the module offers the possibility to signal the existence of a new diagnostic message through the process data. To do this, the object New message available can optionally be mapped to the process data.
