3-16 Configuring the Adapter
By default, when communications are disrupted (for example, a cable is
disconnected) or the scanner is idle, 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 10 - [Comm Flt Action]
and a different response to an idle scanner using Parameter 11 - [Idle
Flt Action] .
To change the fault action
•
Set the values of Parameters 10 - [Comm Flt Action] and 11 - [Idle
Flt Action] to the desired responses:

Changes to these parameters take effect immediately. A reset is not
required.
Setting a Fault Action
!
ATTENTION: Risk of injury or equipment damage exists.
Parameters 10 - [Comm Flt Action] and 11 - [Idle Flt Action] let you
determine the action of the adapter and connected drive if
communications are disrupted or the scanner is idle. By default, these
parameters fault the drive. You can set these parameters so that the drive
continues to run. Precautions should be taken to ensure that the settings
of these parameters do not create a hazard of injury or equipment
damage.
Value Action Description
0 Fault (default) 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 after a
communications disruption. This does not
command a stop.
3 Hold Last The drive continues in its present state after a
communications disruption.
4 Send Flt Cfg The drive is sent the data that you set in the fault
configuration parameters (Parameters 15 - [Flt Cfg
Logic] through 24 - [Flt Cfg D2 In]).
