Remark
Write operation is valid
when "alarm manner
control byte" is 0 or 2
High byte: binary input
status (note)
Low byte: binary output
status
0: turn off alarm function
1: relay output 1 is used
for alarm
From low to high, each
bit means status of an
alarm group:
0: no alarm activated
1: in alarm status
