Parameter
& Data Type
Enter
18 Build data frame in SDM-CAN memory; 4-byte IEEE floating
point number; least significant byte first. Logical "OR" with
existing data.
19 Transmit data value to the CAN-bus; unsigned integer, most
significant byte first.
20 Transmit data value to the CAN-bus; unsigned integer, least
significant byte first.
21 Transmit data value to the CAN-bus; signed integer, most
significant byte first.
22 Transmit data value to the CAN-bus; signed integer, least
significant byte first.
23 Transmit data value to the CAN-bus; 4-byte IEEE floating point
number; most significant byte first.
24 Transmit data value to the CAN-bus; 4-byte IEEE floating point
number; least significant byte first.
25 Transmit previously built data frame to the CAN-bus.
26 Set up previously built data frame as a Remote Frame Response.
27 Read Transmit, Receive, Overrun, and Watchdog errors. The
errors are placed consecutively in the array specified by the Dest
parameter.
28 Read Transmit, Receive, Overrun, and Watchdog errors. The
errors are placed consecutively in the array specified by the Dest
parameter. Reset error counters to 0 after reading.
29 Read SDM-CAN status; result is placed into the array specified
in the Dest parameter. The result codes are as follows:
Status Description
0000 The SDM-CAN is involved in bus activities; error
counters are less than 96.
0001 The SDM-CAN is involved in bus activities; one or
more error counters is greater than or equal to 96.
0002 The SDM-CAN is not involved in bus activities;
error counters are less than 96.
0003 The SDM-CAN is not involved in bus activities; one
or more error counters is greater than or equal to 96.
30 Read SDM-CAN operating system and version number; results
are placed in two consecutive array variables beginning with the
variable specified in the Dest parameter.
31 Send Remote Frame Request.
32 Set SDM-CAN's internal switches. The code is stored in the
array specified in the Dest parameter and is entered in the form
of ABCD.
Switch Code Description
A 0 Currently not used; set to 0.
B 0 SDM-CAN returns the last value captured
from the network, even if that value has
been read before (default).
