Transmit data value to the CAN-bus; 4-byte IEEE floating point
23
number; most significant byte first.
Transmit data value to the CAN-bus; 4-byte IEEE floating point
24
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.
Read Transmit, Receive, Overrun, and Watchdog errors. The
27
errors are placed consecutively in the array specified by the Dest
parameter.
Read Transmit, Receive, Overrun, and Watchdog errors. The
28
errors are placed consecutively in the array specified by the Dest
parameter. Reset error counters to 0 after reading.
Read SDM-CAN status; result is placed into the array specified in
29
the Dest parameter. The result codes are as follows:
Status
Description
The SDM-CAN is involved in bus activities; error
0000
counters are less than 96.
The SDM-CAN is involved in bus activities; one or
0001
more error counters is greater than or equal to 96.
The SDM-CAN is not involved in bus activities; error
0002
counters are less than 96.
The SDM-CAN is not involved in bus activities; one or
0003
more error counters is greater than or equal to 96.
Read SDM-CAN operating system and version number; results are
30
placed in two consecutive array variables beginning with the
variable specified in the Dest parameter.
31
Send Remote Frame Request.
Set SDM-CAN's internal switches. The code is stored in the array
32
specified in the Dest parameter and is entered in the form of
ABCD.

SDM-CAN returns the last value captured
from the network, even if that value has
been read before (default).
SDM-CAN returns -99999 if a data value is
requested by the datalogger and a new
value has not been captured from the
network since the last request.
Currently not used.
Disable I/O interrupts (default).
Enable I/O interrupts, pulsed mode.
Enable I/O interrupts, fast mode.
Currently not used.
Place the SDM-CAN into low power stand-
by mode
Leave switch setting unchanged.
Listen only (error passive) mode. CAN
transmissions are not confirmed.
