3.10 Setting the Communications Fault Action
The communications fault action determines how the VSM500 unit and DeviceNet
option board respond when communications are disrupted (e.g., disconnected cable).
By default, the VSM500 unit is faulted and stopped. You can change this setting if your
application requires a different setting.
Step 1. In the Device Configuration - Enhanced Mode dialog box (see figure 3.8),
double-click parameter 109 [
DNET
FAULT
MODE
]. The Device Configuration -
Modify Boolean Parameter dialog box appears.
Step 2. Select the appropriate setting for your application, and then click Save to
Device.
Step 3. Click OK to close the dialog box.
!
ATTENTION: Parameter 109 [
DNET
FAULT
MODE
] determines the action
of the option and connected VSM500 unit if communications are
disrupted. By default, this parameter faults and stops the VSM500 unit.
You can set this parameter so that the VSM500 unit continues to run.
Precautions should be taken to ensure that the setting of this parameter
does not create a hazard of injury or equipment damage. Failure to
observe these precautions could result in bodily injury or damage to
equipment.
