Can Xenta I/O modules be added directly to a Lon network?

Issue

Can Xenta I/O modules be added directly to a Lon network?

Product Line

SmartStruxure Solution

Environment

Xenta I/O modules

StruxureWare Building Operations Enterprise Server (ES) or Automation Server (AS)

Cause

The Building Operation ES/AS structure allows I/O modules to operate without an Xenta base unit.

Resolution

The following Xenta I/O modules can be added directly once the Lon interface and network has 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.
