AKT2G-SM-Lxx Diagnostic Messages

DiagMessages designates a system for the transmission of messages from the EtherCAT***EtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs Slave to the EtherCAT Master. The messages are stored by the device in its own CoE under 0x10F3 and can be read by the application. An error message referenced via a code is output for each event stored in the device (warning, error, status change). Diagnostic messages can be viewed from the Diagnostics Tab in the AKT2G-SM-Lxx Stepper Drive Configuration Tab.

Definition

The DiagMessages system is defined in the ETG (EtherCAT Technology Group) in the guideline ETG.1020, chapter 13 “Diagnosis handling”. It is used so that pre-defined or flexible diagnostic messages can be conveyed from the EtherCAT Slave to the Master. In accordance with the ETG, the process can therefore be implemented supplier-independently. Support is optional. The firmware can store up to 250 DiagMessages in its own CoE.

Each DiagMessage consists of

Diag Code (4-byte)
Flags (2-byte; info, warning or error)
Text ID (2-byte; reference to explanatory text from the ESI/XML"Extensible Markup Language " XML is a general-purpose markup language. It is classified as an extensible language because it allows its users to define their own tags)
TimestampA timestamp is a sequence of characters, denoting the date and/or time at which a certain event occurred (8-byte, local slave time or 64-bit Distributed Clock time, if available)
Dynamic parameters added by the firmware

The DiagMessages are explained in text form in the ESI/XML file belonging to the EtherCAT device: on the basis of the Text ID contained in the DiagMessage, the corresponding plain text message can be found in the languages contained in the ESI/XML.

Via the entry NewMessagesAvailable the user receives information that new messages are available.

DiagMessages can be confirmed in the device: the last/latest unconfirmed message can be confirmed by the user.

In the CoE both the control entries and the history itself can be found in the CoE object 0x10F3:

The subindex of the latest DiagMessage can be read under x10F3:02.

Support for commissioning

The DiagMessages system is to be used above all during the commissioning of the plant. The diagnostic values e.g. in the StatusWord of the device (if available) are helpful for online diagnosis during the subsequent continuous operation.
