The EAP Object Dictionary is divided into standard and profile-specific objects. Standard objects have the same meaning for all modules. The profile-specific objects have the same meaning for all modules that support the profile type 5002. Beyond that, objects can be static or dynamic. A static object exists as long as the instance of an EAP device itself. A dynamic object can be generated and also deleted again during the runtime of the EAP device.
The division of the object dictionary
The Object Dictionary of the EAP device is divided into the following ranges:
▪
Index 0x1000 – 0x1FFF: Range that describes the communication profile.
General information on the identity of the device such as name, vendor, serial number, etc. are saved in the range 0x1000 – 0x1018.
Furthermore, PDO Mapping objects (PDO = ProcessDataObject) are defined in the ranges 0x1600 – 0x17FF and 0x1A00 – 0x1BFF. A PDO Mapping defines which contents of other objects of the OD are summarized to form a PDO. A PDO then describes the contents of the user data, which is cyclically transmitted in real-time.
▪
Index 0x6000 – 0x9FFF: Range that describes functionally relevant parameters.
The functionally relevant parameters are specified in the ETG standard 1005. The parameters including their structure are defined under the device profile number 5002, module profile 1000. This definition forms the basis for effecting an exchange of data via the EtherCAT Automation Protocol. The following section deals with the individual object types of the profile as well as their structural relationships.
▪
Index 0xF000 – 0xFFFF: Range that describes the device-specific properties.
In this range there are objects with whose help diagnostic and control functions can be carried out with the TwinCAT EAP device.
The object types of the standardized profile range and their structure
In the following, the dynamic objects are listed and their relationship with one another is explained. The illustration above shows the relationships:
Objects for parameterizing a Subscriber:
▪
RxVariable [0x7000+n … 0x7FFF]:
An RxVariable defines a variable of any type that can be linked with a corresponding input variable of a control application (e.g. PLC).
▪
RxProcessDataObject (RxPDO) [0x1600+n … 0x17FF]:
An RxPDO defines an ordered quantity of RxVariables that represent an item of process data as a unit.
▪
RxProcessData (RxPD) [0xE000+4*n … 0xEFFC]:
An RxPD defines the properties for the reception of a PDO (see
Subscriber Box and
Subscriber Variable). The RxPD thus represents the main reception unit of the EAP communication.
▪
RxProcessDataInfo [0xE002+4*n … 0xEFFE]:
An RxPDInfo object expands the RxPD object by individual properties that are not found in the EAP specification and especially belong to a TwinCAT EAP device.
Objects for parameterizing a Publisher:
▪
TxVariable [0x6000+n … 0x6FFF]:
A TxVariable object defines a variable of any type that can be linked with a corresponding output variable of a control application (e.g. PLC).
▪
TxProcessDataObject (TxPDO) [0x1A00+n … 0x1BFF]:
A TxPDO defines an ordered quantity of TxVariables that represent an item of process data as a unit.
▪
TxProcessData (TxPD) [0xD000+4*n … 0xDFFC]:
A TxPD object defines the properties for transmitting a PDO (see
Publisher Variable). The TxPD thus represents the main transmission unit of the EAP communication.
▪
TxProcessDataInfo [0xD002+4*n … 0xDFFE]:
A TxPDInfo object expands the TxPD object by individual properties that are not found in the EAP specification and especially belong to a TwinCAT EAP device.
▪
TxFrame [0x8000+n*8 ... 0x8FF8]:
A TxFrame object defines the transport properties with which one or more TxPDs are transmitted within the network (see
Publisher Box).
▪
TxPD Assignment [0x8001+n*8 … 0x8FF9]:
A TxPDAssignment object is assigned to each TxFrame object. The TxPDAssignment object has the index one higher than that of the TxFrame object. The assignment object specifies which TxPDs are sent together in the corresponding TxFrame.
▪
TxFrameInfo [0x8002+n*8 … 0x8FFA]:
A TxFrameInfo object expands the TxFrame object by individual properties that are not found in the EAP specification and especially belong to a TwinCAT EAP device.

CoS On Change Timeout

Poll Request TxPD
Poll Request TxPD defines the object index of a TxProcessData, which is sent as a request in order to receive an EAP telegram with the suitable ProcessData.

Timeout Poll Response
Specifies the maximum time span in µs within which the response to the Polled Request must be received.
If the Value > 0 and the timeout has expired following the sending of the Polled Request, then bit 2 is set in PD State (subindex 12).
If the value is 0, then this monitoring is deactivated.
