Adapter Parameters Appendix B
40
41
[Peer A Input]
[Peer B Input]
Sets the destination of the peer I/O input. The
adapter receives this data from the network and
sends it to the drive.
Important: Changes to these parameters are
ignored when Parameter 49 - [Peer Inp Enable] is
set to ‘1’ (On).
Important: If the parameter is set to input a Logic
Command, configure the mask in Parameter 42 -
[Peer Cmd Mask] so that the desired bits from the
peer device are used.
Default: 0 = Off
Default: 0 = Off
Values: 0 = Off
1 = Cmd/Ref
2 = Datalink A Input
3 = Datalink B Input
4 = Datalink C Input
5 = Datalink D Input
Type: Read/Write
Reset Required: No
42 [Peer Cmd Mask]
Sets the mask for the Logic Command word when
it is received through peer input. If the mask bit is
‘0’ (Off), the command bit is ignored and not used.
If the mask bit is ‘1’ (On), the command bit is
checked and used.
Important: If the adapter receives a Logic
Command from both a Master device and a peer
device, each command bit must have only one
source. The source of command bits set to ‘0’ will
be the Master device. The source of command bits
set to ‘1’ will be the peer device.
Default: 0000 0000 0000 0000
Minimum: 0000 0000 0000 0000
Maximum: 1111 1111 1111 1111
Values: 0 = Ignore bit
1 = Check bit
Type: Read/Write
Reset Required: Yes
43 [Peer Flt Action]
Sets the action that the adapter and drive will take
if the adapter detects that peer I/O communication
has been disrupted. This setting is effective only if
I/O is transmitted through the adapter.
Default: 0 = Fault
Values: 0 = Fault
1 = Stop
2 = Zero Data
3 = Hold Last
4 = Send Flt Cfg
Type: Read/Write
Reset Required: No
Parameter
No. Name and Description
Details
ATTENTION: Risk of injury or equipment damage exists. Parameter 43 - [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, however, precautions should be taken to verify that the setting
of this parameter does not create a risk of injury or equipment damage. When
commissioning the drive, verify that your system responds correctly to various
situations (for example, a disconnected cable).
