To set up the slave (receiver) side of simple Peer I/O:
1. 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.
2. Set Parameters 81 - [Fr Peer Addr 1] through 84 - [Fr Peer Addr
4] to the IP address of the drive transmitting Peer I/O.
3. In each PowerFlex 750-Series slave drive, set drive parameter 308 -
[Direction Mode] to “1” (Bipolar) to ensure that it properly follows
the master drive’s speed reference and commanded direction.
4. Set Parameter 85 - [Fr Peer Enable] to a value of “1” (Cmd/Ref).
Custom Peer I/O Configuration
Peer I/O also allows more flexibility in sending custom data over the
network, but requires more configuration.
Important: Because of the 32-bit REAL (floating point) Reference, the
following method works only if the drives transmitting and
receiving are PowerFlex 750-Series drives.
To set up the master (broadcast) side of custom Peer I/O:
1. Decide how many Datalink parameters you want to transmit. Set
Parameter 87 - [DLs To 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 87 - [DLs To Peer Cfg] is set to “3,” then 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 35 - [DLs To
Net Act] plus Parameter 87 - [DLs To Peer Cfg] does not total
more than 16.
3. Set Parameters 17 through 32 - [DL To Net 01-16] to the
parameters you want to transmit, based on the allocation in Step 2.
4. Reset the adapter by power cycling the drive or by using the HIM’s
Reset Device function located in the drive’s DIAGNOSTIC folder
so that changes to Parameter 87 - [DLs To Peer Cfg] take effect.
