DO alarm detection
lthough fixed signals such as SKIP cannot be used, allocating DI
addresses starting from X0008 allows the *DECn signal to be used and
the *ESP fixed signal to be allocated to an address for which the common
voltage is fixed to 24 V.
(Fixed signals cannot be allocated to the for the matrix input signals.)
Matrix input signal
Turning the DO (output signal) power on and off (DOCOM)
All the DO signals can be turned off simultaneously by turning off
(opening) the DO (output signal) power supply pin "DOCOM".
Doing so causes the DO signal status to change as shown below.
