Data Coding
Although decimal notation is generally used for data in this manual, data is
handled in the system as binary-coded decimal (BCD) unless otherwise
noted. Note that this data is generally input as decimal, whereas hexadeci-
mal data is input as hexadecimal. The number of digits given for certain data
refers to the decimal digits. For example, ”7 digits with direction” indicates
that the lowest word and rightmost 12 bits of the highest word are allocated
to the 7-digit decimal value; the leftmost four bits are allocated to the direc-
tion digit.
3–6 Flags and Other Input Data
IR words n+5 to n+9 are allocated to flags and other inputs that supply infor-
mation about positioning system operation. Although some of these are de-
scribed under specific operations or commands, they are presented together
in Appendix D IR Area Allocations for convenience. Of these, an output code
has been provided for user application and four signals, the last four in the
list, have been provided for system debugging.
3–7 DM Area Allocation
Coding Sheet
The table on the following page can serve as a general coding sheet for the
DM area. For a more detailed table describing the functions of all of the bits
in the DM area, see Appendix C DM Area Allocations.
The numbers shown for the DM words in the following table represent only
the final two digits of each word number. In other words, the first two digits
(which would be the same for all words) are not shown. The value of the first
two digits can be obtained by computing the first DM word allocated to the
Unit. This word, designated m, is equal to 1000 plus 100 times the unit num-
ber. Thus, for example, it would be 1000 for Unit #0, 1100 for Unit #1, and so
on.
