3.5 Device Configuration
In T-Scheme mode, one command can be configured with additional properties:
•
Line 1: the command can be transmitted on LID-1. Unchecking the configuration will disable command
transmission on LID-1
•
Line 2: the command can be transmitted on LID-2. Unchecking the configuration will disable command
transmission on LID-2
•
T command: the command can be forwarded to another transmission line. This configuration takes effect
on both lines. It would disable the local input / output automatically by setting a command as T
command; and it would need to be manually re-enabled, if the user really intended to have a command
allocated to local ports while being forwarded.
For example:
•
Command 1..4: Both device 1<>2 and device 2<>3
•
Command 5..8: Device 1 <> 2, and device 1 <> 3 (routed via device 2)
•
Command 9..12: Device 3 <> 2, and device 3 <>1 (routed via device 2)
•
Command 13..16: Device 1<>3
[sc_command_input_output_allocation, 2, --_--]
The forwarded command (T cmd) and line selections are configured in the form of PowerSys > SWT 3000 >
Configuration > Output Allocation. In this example, four different groups of commands are configured.
