Issue
There is a need for Xenta I/O modules to be added as standalone devices on a Lon network.
Product Line
EcoStruxure Building Operation
Environment
- Xenta I/O modules
- Building Operation Enterprise Server
- Building Operation Automation Server Premium
- Building Operation Automation Server
Cause
The Building Operation ES/AS structure allows I/O modules to operate without a Xenta programmable base unit.
Resolution
The following Xenta I/O modules can be added directly once the Lon interface and network have been created:
| I/O Module | DI | DI status | DO | DO override | UI | TI | AO | AO override |
| Xenta 421A | - | - | 5 | - | 4* | - | - | - |
| Xenta 422A | - | 4** | 5 | 5 | 4* | - | - | - |
| Xenta 451A | - | - | - | - | 8* | - | 2 | - |
| Xenta 452A | - | 8** | - | - | 8* | - | 2 | 2 |
| * - DI, 0–10 V DC or 0–20 mA, 1.8/10 kohm TI | ||||||||
| ** - Status indication only when the corresponding universal inputs (UI) are being used as digital inputs. |
||||||||
Once the I/O module is set up for SNVT communication the green LED will flash once every 10 seconds.
