Minor Events – Corrective Actions
When the TeSys island encounters a minor event:
-
The fieldbus and service ports remain activated.
-
Only the System avatar is activated.
-
All power modules and I/O modules are in the device Off state.
-
To exit a minor event state that is not automatically recovered, a system reset, restart, or control power cycle is required. A system reset command can be issued manually from the TeSys island DTM, the OMT, or the PLC.
The following scenarios cause the island to encounter a minor event:
Minor Events and Corrective Actions
|
Minor Event |
Diagnosis |
Corrective Action |
|---|---|---|
|
Topology mismatch |
The island configuration in the active context file does not match the actual discovered topology of the island |
Determine the proper configuration and align the configuration with the physical hardware The OMT and the DTM have a compare function in the diagnostics views to compare the topology. Perform one of the following:
|
|
Switch off island command |
Island received Switch Off Island command |
N/A |
|
Too many modules |
The number of physical modules detected in the island is beyond the maximum allowed limit of 21 |
|
|
No modules on island |
There are no physical modules installed on the island |
Complete the installation of the modules on the island |
|
Control voltage 120% |
The voltage was over 120% for longer than the allowed duration |
Verify that the power supply voltage is within range |
|
Firmware update unsuccessful |
Firmware download to the device was unsuccessful after three consecutive tries |
|
|
Summary file integrity check |
Configuration file corruption detected |
|
|
Context file integrity check |
Configuration file corruption detected |
|
|
Avatar settings file integrity check |
Configuration file corruption detected |
|
|
Avatar settings file malformed |
Configuration file corruption detected |
|
|
No active project file |
Bus Coupler is not configured with an active project file |
Configure Bus Coupler using engineering tools |
|
Range of voltage supply |
Confirm the sufficient voltage supply |
In order to run the TeSys island, the voltage supply must be higher than 20.7 V. |
