5. Set Parameters 89 - [To Peer Period] and 90 - [To Peer Skip] as
required for your application. Parameter 89 controls how frequently
the adapter will transmit present data. Parameter 90 controls how
many transmit opportunities can be skipped if the data to be
transmitted has not changed.
6. Set Parameter 91 - [To Peer Enable] to a value of “2” (Custom).
To set up the slave (receiver) side of custom Peer I/O:
1. Decide how many pieces of data (Logic Command, Reference, and
Datalink parameters) you want to receive. This must match the
number of parameters transmitted by the master. Set Parameter 76
- [DLs Fr Peer Cfg] to that value.
2. Determine how the Datalinks are allocated. The highest numbered
of the 16 Datalinks are allocated to Peer I/O. For example, if
Parameter 76 - [DLs Fr Peer Cfg] is set to “3,” Datalinks 14, 15,
and 16 are allocated to Peer I/O. To avoid an overlap between
Master-Slave and Peer I/O, make sure that Parameter 34 - [DLs
From Net Act] plus Parameter 76 - [DLs Fr Peer Cfg] does not
total more than 16.
3. Set Parameters 1 through 16 - [DL From Net 01-16] to the
parameters you want to receive, based on the allocation in Step 2.
4. Set Parameter 80 - [Fr Peer Timeout] to a suitable timeout value
for your application. This value should be greater than the product
of Parameter 89 - [To Peer Period] and Parameter 90 - [To Peer
Skip] in the transmitting drive.

5. Set Parameter 56 - [Peer Flt Action] to the desired action if Peer
I/O data is not received before the timeout is reached.

ATTENTION: Risk of injury or equipment damage exists.
Parameter 56 - [Peer Flt Action] lets you determine the
action of the adapter and connected drive if the adapter is
unable to communicate with the designated peer. 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. When commissioning
the drive, verify that your system responds correctly to
various situations (for example, a disconnected cable).
