Report Alarm
[0x3D]
Raises alarms based on reset alarm ID [63,0,173]. Possible uses of this
command are:
Raising an alarm based on conditions that are either not input to or not
detectable by the DL8000 (such as a fire detection system or a PLC being
used to monitor a rail car’s position).
Stopping a batch with a situation-specific message. In this case, the TAS
might configure a safety circuit alarm message via communications and
then raise the corresponding safety circuit alarm. The TAS can reset the
alarm using the reset primary alarms command [0x14].
Note
: A TAS should
not
depend on DL8000 alarms to prevent or control
hazardous or life-threatening conditions.
