Rockwell Automation 22-COMM-B PowerFlex BACnet MS/TP Adapter - Manual (Page 34)

3-6 Configuring the Adapter
By default, when communications are disrupted (for example, a cable is
disconnected), the drive responds by faulting if it is using I/O from the
network. You can configure a different response to communication
disruptions using Parameter 02 - [Comm Loss Action].
Changing the Comm Loss Action
Set the value of Parameter 02 - [Comm Loss Action] to the desired
response action:
Figure 3.5 Example Comm Loss Action HIM Screen
Changes to this parameter takes effect immediately. A reset is not
required.
Setting a Comm Loss Action
!
ATTENTION: Risk of injury or equipment damage exists.
Parameter 02 - [Comm Loss Action] lets you determine the action of
the adapter and connected drive if communications are disrupted. By
default, this parameter faults the drive. You can set this parameter so
that the drive continues to run. Take precautions to ensure that the
setting of this parameter does not create a risk of injury or equipment
damage. When commissioning the drive, verify that your system
responds correctly to various situations (for example, a disconnected
cable).
Value Action Description
0 Fault The drive is faulted and stopped. (Default)
1 Stop The drive is stopped, but not faulted.
2 Zero Data The drive is sent 0 for output data. This does not command a stop.
3 Hold Last The drive continues in its present state.
4 Send Flt Cfg The drive is sent the data that you set in the fault configuration
parameters (Parameter 04 - [Flt Cfg Logic] and Parameter 05 -
[Flt Cfg Ref]).
