Overview
System monitoring lets you obtain information about operating states of TeSys devices by using the diagnostic engine. The engine sends requests to their IP address and monitors responses.
The state of the device is indicated by a diagnostic icon in the physical view in which the device appears.
Detection Method
The diagnostic engine that runs on the computer acting as Control Expert server sends Modbus TCP requests to TeSys devices by using the IP address of their embedded interface to obtain information about their state.
States Indicated by Diagnostic Icons
The table describes which operating states can be represented on TeSys T devices displayed in a physical view and the icons that are used. Their description is indicated in a tooltip.

Description |
Device state description |
---|---|---|
Not fully operational(1). Blue diamond. |
Bit 3 of the register 455 status word = 1 (system status register 1). |
|
Out of Order/Not operational(1). Yellow triangle. NOTE: Can also indicate an incompatibility or mismatch between
the configured and the physical object.
|
Bit 2 of the register 455 status word = 1 (system status register 1). The operating state of the device is Fault. |
|
(1) Implies that the device is reachable and responded. |
The table describes which operating state can be represented on TeSys island devices displayed in a physical view and the icon that is used. Its description is indicated in a tooltip.
