Although 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.)

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.
