Configuring the Option Module Chapter 3
Setting a Fault Action By default, when communication is disrupted (for example, the network 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 these faults:
• Disrupted I/O communication by using Host Parameter 33 - [Comm Flt
Action] .
• An idle controller by using Host Parameter 34 - [Idle Flt Action].
Changing the Fault Action
Set the values of
Host Parameters 33 - [Comm Flt Action] and 34 - [Idle Flt
Action] to an action that meets your application requirements.
Figure 5 - Edit Fault Action HIM Screens
Changes to these parameters take effect immediately. A reset is not required.
If communication is disrupted and then is re-established, the drive will
automatically receive commands over the network again.
ATTENTION: Risk of injury or equipment damage exists. Host
Parameters 33 - [Comm Flt Action] and 34 - [Idle Flt Action] let you
determine the action of the option module and connected drive if
communication is disrupted or the scanner is idle. By default, these
parameters fault the drive. You may configure these parameters so that the
drive continues to run, however, precautions should be taken to verify that
the settings of these parameters do 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 network cable
or controller in idle state).
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’ values for 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 (Host Parameters 37 - [Flt Cfg Logic], 38 - [Flt Cfg Ref], and
39 - [Flt Cfg DL 01] through 54 - [Flt Cfg DL 16]).
