It is organized in words: each of the 16 bits of a word can
represent the state of an output. It is accessible also in bits, in
order to allow the control of each single output.
5.5 Area of Marker M
Memory area M is comprised of
50 words
and contains the state
of all the markers (contact bits) used in the program.
It is organized in words: each of the 16 bits of a word represents
the state of a marker. For example, the state of the marker M5 is
memorized in the bit 4 of word 1 in memory area M. The marker
M5 is thus accessible as M1.4 (contact bit of the word), but also as
single bit M5 (contact or electrical relay coil).
5.6 Area of Analog Inputs AI
Memory area AI is composed of
32 words
and can be used to
contain the state of the analog inputs read from the serial lines of
other devices.
It is organized in words: each can represent the state of an analog
input
5.7 Area of Analog Outputs AQ
Memory area AI is composed of
32 words
and can be used to
contain the state of the analog outputs read from the serial line of
other devices
It is organized in words: each can represent the state of an analog
output.
5.8 Areas of Timer T and Preset Timer PT
The area of memory for timer T is composed of
128 words
. If the
timer is enabled, the variation of the contents of the area of
memory is regulated by the type of timer, which is set at the
