(LSB)
Bit position
The correspondence between register data and device data should be
considered as follows.
Example)
When it is said that the content of XW005 is 100, since the
decimal number 100 is expressed as 1100100 in binary
notation, this indicates that each of the bits of XW005 will be
as follows.
At this time, the data of device X0056 corresponding to bit position “6” of
XW005 is 1, that is to say X0056 is ON.
The correspondence of registers and devices is shown by function
types.
●
Input device (X) ... corresponds to 1 bit of input register (XW)
●
Output device (Y) ... corresponds to 1 bit of output register (YW)
●
Auxiliary device (R) ... corresponds to 1 bit of auxiliary register (RW)
●
Special device (S) ... corresponds to 1 bit of special register (SW)
●
Link device (Z) ... corresponds to 1 bit of link register (W)
●
(but only in the leading 1000 words)
Link relay (L) ... corresponds to 1 bit of link register (LW)
The treatment of the other devices, I, O, T. and C., is slightly different. It
is described in detail in Section 3.2.
