5 I/O Signal Allocation
5.2 Transmission Data
The relationship between the write contents and the output voltage values
of the registers M560 to M561 are shown below.
Output voltage value
+14 V
8010H
Although the register setting value is 16-bit wide, the lower 4 bits of the
write content are invalid because the D/A resolution is 12 bit. (The output
voltage values of the write contents ***0H to ***FH are the same.)
Also, the write contents 8000H to 800FH are not used.
The relationship between the input voltage and the read contents of the
registers M600 to M601 are shown below.
Input voltage value
+5 V
8000H
The allocation of the concurrent I/O is shown above, but note that only the
2 analog inputs, 2 analog outputs, 5 contact inputs, and 4 contact outputs
can be used for communication between the JANCD-YEW01-E board and
external devices.
The contact inputs and outputs other than described above are used by
the system, so they cannot be used for communications with external
devices.
