4-2 Peripheral Device Operations and Data Setting
This section explains how to use a peripheral device such as the Program-
ming Console to turn I/O bits ON and OFF, to change present values, and how
to start up Cam Positioner Unit operations and set data.
For these operations, preset the operation mode selector to RUN.
In the examples, the Unit number is set to “0,” and the procedure for the Pro-
gramming Console is shown.
DM number Data item Data contents
DM m Cam data storage, leading
DM number The leading general DM number for storing cam data is set in
4 digits BCD (0000 to 0985).
DM (m+1) Cam data storage, number
of combinations The number of combinations (i.e., the number of combinations
of DM x bank numbers and cam numbers) for stored cam data
is set in 4 digits BCD (0001 to 0008).
DM (m+2) Transfer of data permitted/
not permitted for number of
revolutions required for a
single process This is used when transferring from the C200H to the Cam
Positioner Unit the data stored in DM m + 3 to DM m + 10 (i.e.,
the number of revolutions required for a single process).
Odd: Transfer permitted
Even: Transfer not permitted
DM (m+3) to DM (m+10) Setting data for number of
revolutions required for a
single process
DM m + 3 to DM m + 10 correspond to Banks 1 to 8. The
data for the applicable bank is set according to the bank
number set in word n + 1.

DM number Data item Data contents
DM x Bank no. Bank numbers for the cam data in DM x + 1 to DM x + 14 is
set in bits 15 to 08, in 2-digit BCD.
Cam no. Cam numbers for the cam data in DM x + 1 to DM x + 14 is set
in bits 07 to 00, in 2-digit BCD.
DM (x+1) to DM (x+14) Cam ON/OFF data
This is the cam ON/OFF data for steps 1 to 7. When down-
loading memory, set the data in this area. When uploading
memory, retrieve the data in this area.
