Codes
Auxiliary registers ... RW
Auxiliary devices... R
Addresses
Output registers... 000-255 (256 words)
Output devices... 0000-255F (corresponding to one bit in a register,
4096 points)
Functions
These are general purpose registers/general purpose devices which
can be used for temporary storage of execution results during a
program.An auxiliary register is used for storing 16-bit data. An auxiliary
relay indicates 1 bit in an auxiliary register.
Auxiliary registers/relays can be designated as retentive memory areas.

Addresses
Special registers... 000-255 (256 words)
Special devices... 0000-255F (corresponding to one bit in a register,
4096 points)
Functions
These are registers/devices which have special functions such as fault
flags (Error down/Warning) which are set when the CPU detects a
malfunction; timing relays and clock calendar data (year, month, day,
hour, minute, second, day of week) which are updated by the CPU;
flags/data which the user sets for executing operational control of the
sub-programs. For details, see the Table
Codes
Timer registers... T
Timer devices... T.
Addresses
Timer registers... 000-511 (512 words)
Timer devices... 000-511 (512 points)
Functions
The timer registers are used together with timer instructions (TON,
TOF, SS, TRG), and store elapsed time (increment system) when the
timer is operating. Also, the timer devices are linked to the operation of
the timer registers with the same address, and store the output results
of timer instructions. T000 to T063 works as 0.01 sec timers and T064
to T511 works as 0.1 sec timers. The timer registers can be designated
as retentive memory areas.
Codes
Counter registers... C
Counter devices... C.
Addresses
Counter registers... 000-511 (512 words)
Counter devices... 000-511 (512 points)
Functions
The counter registers are used together with counter instructions (CNT,
U/D), and store the count current value when the counter is operating.
Also, the counter devices are linked to the operation of the counter
registers with the same address, and store the output results of counter
instructions. The counter registers can be designated as power cut
retention areas.
