Diagnosis - Diag Messages
EL70x1234 Version: 4.4
6.2 TwinCAT System Manager implementation
From TwinCAT 2.11 DiagMessages, if available, are displayed in the device’s own interface. Operation
(collection, confirmation) also takes place via this interface.

The operating buttons (B) and the history read out (C) can be seen on the Diag History tab (A). The
components of the message:
• Info/Warning/Error
• Acknowledge flag (N = unconfirmed, Q = confirmed)
• Time stamp
• Text ID
• Plain text message according to ESI/XML data
The meanings of the buttons are self-explanatory.
6.3 Interpretation
Structure of the Text ID
The structure of the MessageID is not subject to any standardization and can be supplier-specifically
defined. In the case of Beckhoff EtherCAT devices (EL, EP) it usually reads according to xyzz:
x y zz
0: Systeminfo
1: Info
4: Warning
8: Error
1: General
2: Communication
3: Encoder
4: Drive
5: Inputs
Error number
Sample: Message 0x4413 --> Drive Warning Number 0x13
General Text IDs
Specific Text IDs should be specified in the device documentation.
