Alarm onset statuses are outputted with channels assigned to each bit. (CH1
is assigned to the most significant bit [MSB].) An analog output and waveform
calculation output are represented by eight characters (32 bits); pulse output and
logic output are represented by two characters (8 bits). The letter H is added at the
end.
Example: When U1-1 issues an alarm, the alarm source output is
represented by
When a channel generates an alarm the output is represented by
otherwise, represented by
Example: When a logic channel issues an alarm, the output is represented
by .

An alarm source output is represented by 12 characters (11 modules and a
spare bit), in which a character (4 bits) is assigned to each module with an
alarm status incorporated.
A break in a thermocouple, wireless communication error, and low battery
state are in order beginning from the MSB (for plug-in modules, broken
thermocouple only). The letter
Example: When broken thermocouples are found in U2 and U4, the output is
represented by
