3-14 Configuring the Adapter
8. Parameter 34 - [Peer Flt Action] sets the action that the adapter
will take if it times out.
Figure 3.21 Peer Fault Action Screen on an LCD HIM
For details, refer to the Setting a Fault Action section in this chapter.
9. Set Parameter 37 - [Peer Inp Enable] to On. The adapter is now
configured to receive I/O from the specified node. Ensure that the
specified node is configured to transmit I/O.
10. Set Parameter 9 - [Reset Module] to “Reset Module”. The adapter
will reset and the parameter will display “Ready” after the command
has been performed.
The data exchange (sometimes called allocation) is the method that the
adapter uses to exchange data on the DeviceNet network. The adapter
can be configured to use one of the following data exchanges:
If “Polled and COS” or “Polled and Cyclic” is used, the adapter receives
the I/O from the polled messages. It transmits its Logic Status and
Feedback in COS or Cyclic messages. Other data is transmitted in Polled
messages.
Cyclic and Polled data exchanges are configured in the scanner, so you
only need to set the I/O configuration in the adapter. COS data exchange
must be configured in both the adapter and the scanner. You need to set
the I/O configuration and COS parameters in the adapter.
!
ATTENTION: Risk of injury or equipment damage exists.
Parameter 34 - [Peer Flt 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. Precautions should be taken to ensure
that the setting of this parameter does not create a hazard of injury or
equipment damage.
