• Output protection
The internal circuit of this output module can detect a load overcurrent. To
be specific, if the load current increases abnormally, for example, because
of a cable ground fault or an internal DO driver is abnormally heated for
some reason, the protection circuit for the DO driver (4-point unit) works to
keep the output of the DO driver turned off until the cause is removed.
When the overheat protection function works, the LED "F" on the module
lights.

In the analog input module AAD04A, the 4-channel analog input
signals are cyclically A-D converted in order, and the converted digital
data are written in the following addresses. Therefore, in the PMC
program, it is possible at any time to know the values for the analog

Here, D11-n corresponds to the sign bit in the complementary
representation of "2."
In addition, in X-n is written the same value as that in D11-n.
NOTE
1 When addressing I/O modules, the beginning
address for this module should be assigned to an
even one. Moreover, when an A-D converted value is
referred to in a PMC program, make sure to read the
data in unit of a word (16 bits).
2 Note that on the PMC-N, -NA, and -QA (PMC for the

1 When addressing I/O modules, the beginning
address for this module should be assigned to an
even one. Moreover, when an A-D converted value is
referred to in a PMC program, make sure to read the
data in unit of a word (16 bits).
2 This module has a very high resolution. When
A/D-converted values are input to a system for
reference by the PMC program, they may disperse
largely depending on the system. If this is the case,
the dispersion of input values can be suppressed by
obtaining their moving average in the PMC program
or lowering the resolution by masking the
lowest-order bit if possible.
3 Note that on the PMC-N, -NA, and -QA (PMC for the
Series 15 and F-D Mate), the high-order one byte and
low-order one byte of a word (16 bits) are
interchanged with each other as described below.
