8.3 Area of Digital Input I
Memory area I is composed of 32 words and can be used to
contain the state of the digital inputs read through the serial lines
of other devices.
It is organized in words: each of the 16 bits of a word can
represent the state of an input. It is accessible also in bits, in order
to allow the control of each single input.
8.4 Area of Digital Output Q
Memory area Q is composed of 32 words and can be used to
contain the state of the digital outputs to then write them on serial
lines of other devices.
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.
8.5 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).
8.6 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.
