Chapter 3 Configuring the Adapter
6.
Reset the adapter (see
Resetting the Adapter on page 43
) so that changes to
Parameter 42 - [Peer Cmd Mask]
take effect.
7.
Set Parameter 48 - [Peer Inp Timeout] to the maximum amount of time
the adapter will wait for a message before timing out.
Important: This value must be greater than the product of Parameter
54 - [Peer Out Time] multiplied by Parameter 55 - [Peer
Out Skip] in the adapter from which you are receiving I/O.
For example, if the value of Parameter 54 - [Peer Out Time] is 2.00
seconds and the value of Parameter 55 - [Peer Out Skip] is 2 (see
example screen in step 4 on
), then Parameter 48 - [Peer Inp
Timeout]
needs to have a value greater than 4.00, such as 5.00 in the
example screen below.
8.
Set Parameter 43 - [Peer Flt Action] to the action that the adapter will
take if it times out.
For more details, see
Setting a Fault Action on page 41
.
9.
Set Parameter 49 - [Peer Inp Enable] to ‘1’ (On).
The adapter is now configured to receive peer I/O from the specified node.
Ensure that the specified node is configured to transmit peer I/O.
ATTENTION: Risk of injury or equipment damage exists. Parameter 43 -
[Peer Flt Action] lets you determine the action of the adapter and
connected device if peer communication is disrupted. By default, this
parameter faults the device. You can set this parameter so that the device
continues to run, however, precautions should be taken to ensure that the
setting of this parameter does not create a hazard of injury or equipment
damage. When commissioning the device, verify that your system responds
correctly to various situations (for example, a disconnected cable).
