DL8000 Preset Instruction Manual
D-72 Communications Protocols Revised February-2016
Report Alarm
[0x3D]
Raises an alarm based on alarm code received in the command request
frame. Possible uses of this command are:
 Raising an alarm based on conditions that are either not input to or
detectable by 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
automation system might configure a safety circuit alarm message via
communications and then raise the corresponding safety circuit alarm. The
automation system 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.
