Description
Analog, pulse,
waveform
calculation
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
0x80000000H
.
Logic
When a channel generates an alarm the output is represented by
1
;
otherwise, represented by
0
. No letter is added at the end.
Example: When a logic channel issues an alarm, the output is represented
by
1
.
Break in
thermocouple,
wireless
communication
error, low battery
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
H
is added at the end.
Example: When broken thermocouples are found in U2 and U4, the output is
represented by
0x080800000000H
.
