Normal/BCD mode: 13.4 ms (With output ramp and upper/lower limits: 16.6 ms)
High-speed mode: 3.4 ms
2 words (1 input word and 1 output word) or 4 words (2 input words and 2 output words)
Set using the two/four-word operating mode short-circuit pins on the front panel. Factory-set to
two-word operating mode.
Two-word operating mode (factory setting): The CPU Unit directly accesses the Memory Map in
RAM using the I/O WRITE and I/O READ instructions, WRIT and READ.
Four-word operating mode: The CPU Unit accesses the Memory Map in RAM via the allocated I/O
words using the MOV and other instructions.

EEPROM
Two-word operating mode: CPU Rack, Expansion CPU Rack, Expansion I/O Rack, and SYSMAC
BUS/2 Slave Rack (Cannot be mounted to a SYSMAC BUS Slave Rack.)
Four-word operating mode: CPU Rack, Expansion CPU Rack, Expansion I/O Rack, and SYSMAC

62 words: Consists of data that can be accessed by CPU Unit using the
above instructions, including conversion data, scaling upper/lower limits,
upper/lower limit values, BCD mode parameters, binary mode parameters,
etc.
Contains parameter data that can be written from RAM. It transfers data
back to RAM when the power is turned ON.
Specifies whether conversion data, scaling upper and lower limits, upper and
lower limit values, and output ramp set time are to be handled as BCD or
binary data.
Initially sets 16-bit upper and lower limits as a scale and automatically
performs scaling for conversion data (converts it to a rate of 0% to 100%)
according to the initial settings. If lower limit > upper limit, reverse scaling will
be performed (lower limit: 100%, upper limit: 0%).
BCD mode: Decimal values –7999 to 7999 (F999 to 7999
(see note 1)
Binary mode: Decimal values –32767 to 32767 (B001 to 7FFF
(see note 2)
Note 1: Bit 15 is the sign (0: +, 1: –).
Note 2: Two’s complement
Makes output signals change at a specified rate to prevent sudden changes
in response to changes in the present value. Set the time required to change
a present value to a new value.
BCD mode: 8 to 7,999 ms
Binary mode: 8 to 32,767 ms (see 4-3 Two-word Operation for details.)
Makes output signal values constant when conversion data goes beyond a
certain range. (This function can be combined with the scaling function.)
The upper and lower limits can be set within the set data or scaling data
range provided that the upper limit is greater than the lower limit.
Switches the D/A conversion time between normal speed and high speed.
Writes data from RAM to EEPROM (according to the EEPROM Write Bit
setting in the allocated I/O words).
Data is automatically read from EEPROM to RAM when the power is turned
ON. This makes it unnecessary to transfer parameter data from the ladder
program each time.
