Setting the Adapter to Receive Peer-to-Peer Data
1. Verify that Parameter 47 - [Peer Inp Enable] is set to ‘0’ (Off).
This parameter must be Off while you configure the peer input
parameters.
2. Set Parameters 42 - [Peer Inp Addr 1] through 45 - [Peer Inp Addr
4] to the IP address of the node from which you want to receive data.
Valid nodes must have 20-COMM-E adapters connected to drives with
compatible Logic Command/Status words.
3. Set Parameter 38 - [Peer A Input] to select the destination of the data
that is input to the drive as Peer A.
With the Series A adapter, revision 2.xxx or earlier, if you select a
Reference or Datalink as an input, note the following:
– If a drive that uses a 32-bit Reference and 32-bit Datalinks receives a
16-bit Reference or Datalink, it uses the data in its most significant
word, and its least significant word is zero.
– If a drive that uses a 16-bit Reference and 16-bit Datalinks receives a
32-bit Reference or Datalink, it uses the data in the most significant
word of the 32-bit Reference or Datalink and ignores the data in the
least significant word.
With the Series B adapter, revision 3.xxx and later, data is used from the
least significant word in the event of a mismatch in Reference or
Datalink sizes.
