When the left most bit, MSB (the 16-bit command: b15, the 32-bit
command: b31), from
S1
and
S2
is 1, this comparison value will
be viewed as a negative value for comparison.
If the 32-bit length counter (C235~) is put into this command for
comparison, be sure to use the 32-bit command (DLDϠ). If the 16-bit
command (LDϠ) is utilized, CPU will determine it as “ Program Error” ,
and the red “ ERROR” indicator on the MPU panel will be blinking, and
the CPU will not berunning.

Ϩʳ If the content of counter T10 is equal to K100, Y0=ON.
Ϩʳ When the content of D200 is smaller or equal to K –100, and that
X2=ON, Y1 will be set as “ ON” .
Ϩʳ If the content of C235 is smaller than K100, 000, or when X3=ON,
M50=ON.

Compare the contents of
S1
and of
S2
, To take ” AND=” as an
example, if the comparison result is “=” , the contact is in continuity, and
if it is “Ћ” , the contact is in discontinuity. The ANDϠ command is the
comparison command that connects with the series connection
contact.
When the left most bit, MSB (the 16-bit command: b15, the 32-bit
command: b31), from
S1
and
S2
is 1, this comparison value will
be viewed as a negative value for comparison.
If the 32-bit length counter (C235~) is put into this command for
comparison, be sure to use the 32-bit command (DANDϠ). Or if the
16-bit command (ANDϠ) is utilized, CPU will determine it as “ Program
Error” , and the red “ ERROR” indicator on the MPU panel will be
blinking, and the CPU will not berunning.
