Specifications

Command Set 4-11
The alarm limit should be set within the output range of the module. If the
alarm limit is set beyond the output range, the alarm will be activated only
on an overload condition.
The high alarm value may be read back with the Read High Alarm (RH)
command.
A latched alarm may be cleared with the Clear Alarms (CA) command. More
information on alarms may be found in Chapter 6.
IDentification (ID)
The IDentification command allows the user to write a message into the
internal nonvolatile memory which may be read back at any time using the
Read IDentification (RID) command. The message may be up to 16
characters long and has no affect on the module operation. Useful informa-
tion such as the module location, calibration date or model number may be
stored for later retrieval.
The ID command is write protected and checksums are not supported. The
module will abandon any ID command with a message length in excess of
16 characters.
Command: $1IDBOILER ROOM
Response: *
Command: #1IDBOILER ROOM
Response: *1IDBOILER ROOM02
Low Alarm Limit (LO)
The low alarm command sets the value and type of the low alarm. The data
specified with the LO command is stored in nonvolatile memory and
compared with the sensor data after every A/D conversion. If the input data
is less than the low limit, the low alarm is activated. The low alarm status may
be read using the Digital Input (DI) command. The alarm may be used to
activate a digital output by using the Enable Alarms (EA) command. A letter
indicating the alarm type, “L” for latching or “M” for momentary, must follow
the alarm value. For example:
Command: $1LO+00000.00M
Response: *
Command: #1LO+00000.00M
Response: *1LO+00000.00MEC
The alarm limit should be set within the output range of the module. If the
alarm limit is set beyond the output range, the alarm will be activated only
on an overload condition.
