# Initial Communication Settings

Navigation: Valve Firmware > Interface > DeviceNet > Communication > # Initial Communication Settings |

To establish communication via DeviceNet, the following settings should be defined.

1. First to verify if no cyclic communication is active

If Device Status shows Executing than execute stop service (see above)

2. Define Data Type for example under S-Single Stage Controller Object

3. Define Profile and Assemblies

4. Define Data Units

Note: General Device Profile allowed only Counts for Pressure and Position. Default Range is 0-10'000 (Gain value 1). With the gain value this can be limited in a range of 0-1 (Gain value 0.0001) until 0-32767 (Gain value 3.2767)

Pressure (Only necessary to set if Profile is Process Control Device):

Set Gain value if a different range than 0-10'000 is requested (in case of Data Units is Counts).

Position (Only necessary to set if Profile is Process Control Device):

Set Gain value if a different range than 0-10'000 is requested (in case of Data Units is Counts).

5. Restart valve to apply this settings

The easiest way to execute a restart is by pressing restart button on the CPA 4 main window.
