Diag Get Property.vi
Purpose
Gets a diagnostic global internal parameter.
Format
Input
property ID defines the parameter whose value is to be retrieved. You can
create the values using an Enum control.
0 Timeout Diag Command is the timeout in milliseconds the master
waits for the response to a diagnostic request message. The default is
1000 ms.
1 Timeout FC (Bs) is the timeout in milliseconds the master waits for
a Flow Control frame after sending a First Frame or the last
Consecutive Frame of a block. The default is 250 ms.
2 Timeout CF (Cr) is the timeout in milliseconds the master waits for
a Consecutive Frame in a multiframe response. The default is
250 ms.
3 Receive Block Size (BS) is the number of Consecutive Frames the
slave sends in one block before waiting for the next Flow Control
frame. A value of 0 (default) means all Consecutive Frames are sent
in one run without interruption.
4 Wait Time CF (STmin) defines the minimum time for the slave to
wait between sending two Consecutive Frames of a block. Values
from 0 to 127 are wait times in milliseconds. Values 241 to 249
(Hex F1 to F9) mean wait times of 100 µs to 900 µs, respectively. All
other values are reserved. The default is 5 ms.
5 Max Wait Frames (N_WFTmax) is the maximum number of WAIT
frames the master accepts before terminating the connection. The
default is 10.
