7 Diagnostics
The diagnostic LEDs are used to give a first quick overview of the system state.
The diagnostic history in SILworX provides detailed information.
7.1 Light Emitting Diodes
Light emitting diodes (LEDs) on the front plate indicate the module state. All LEDs should be
considered together. The state of one single LED is not sufficient to assess the module state.
A description of the LEDs is provided in the module-specific manuals.
After connecting the supply voltage, an LED test is performed and all the LEDs are lit for at least
2 s. The color of two-color LEDs changes once during the test.
Definition of blinking frequencies
The following table defines the blinking frequencies:
Definition Blinking frequencies
Blinking1 Long (600 ms) on, long (600 ms) off.
Blinking2 Short (200 ms) on, short (200 ms) off, short (200 ms) on, long (600 ms) off.
Blinking-x Ethernet communication: Blinking synchronously with data transmission.
Table 30: Blinking Frequencies of the LEDs
Some LEDs can report warnings (On) and faults or errors (Blinking1), see the following tables.
The indication of errors or faults has priority over the indication of warnings. Warnings cannot be
reported if errors or faults are being signaled.
7.2 Diagnostic History
The modules F-CPU, F-IOP and F-COM keep a history of the faults and other events that have
occurred. The events are stored in the history in chronological order. The history is organized as
a ring buffer.
The diagnostic history is composed of short-term and long-term diagnostics.

Short-term diagnostics
If the maximum number of entries has been reached, each new entry deletes the oldest
entry.

Long term dignostics:
The long term diagnosis essentially stores actions and configuration changes performed by
the user.
If the maximum number of entries has been reached, each new entry deletes the oldest
entry if this is older than three days.
The new entry is rejected if the existing entries are not older than three days. The rejection is
marked by a special entry.
The number of events that can be stored depends on the type of module.
Module type Max. number of events
long term diagnosis Max. number of events

F-CPU 01 2500 1500
F-IOP 01 400 500
F-COM 01 300 700
