Word Bit
Wd m 00 to 15 Reading Count Value
While the Count Value Reading Bit (word n+2, bit 06) is ON, the value will be constantly read and stored
Reading Set Values
While the Set Value 1 Reading Bit (word n+2, bit 04) or the Set Value 2 Reading Bit (word n+2, bit 05) is
ON, the values and the output conditions will constantly be read and stored.
Wd m+1 00 to 15
The sign will be stored
with 1 bit.
0: Positive
1: Negative

BCD (Data Code Switching Bit OFF)
Word n+1
Sign
The sign will be stored in 1-digit hexadecimal.
0: Positive
1: Negative
Hexadecimal (Data Code Switching Bit ON)
Word n+1
BCD (Data Code Switching Bit OFF)
Word n+1
The output conditions will be stored with 3 bits.
000: Present value ≥ Set value → Output ON
Not 000: Present value ≤ Set value → Output ON
(Whether output is actually made depends on the settings of
the External Output Enable Bits, word n+2 bits 08, 09)
Hexadecimal (Data Code Switching Bit ON)
Word n+1
The output conditions will be stored with 3 bits.
000: Present value ≥ Set value → Output ON
Not 000: Present value ≤ Set value → Output ON
(Whether output is actually made depends on the settings of
the External Output Enable Bits, word n+2 bits 08, 09)

Function
Negative numbers will be stored using the 24-bit 2's complement
(the last 24 bits of the 32-bit 2's complement).
Example:For --10,000
--10,000 (decimal) → FFFF D8F0 Hex (32-bit 2's complement) →
FF D8F0 Hex (24-bit 2's complement)
Negative numbers will be stored using the 24-bit 2's complement
(the last 24 bits of the 32-bit 2's complement).
Example:For --10,000
--10,000 (decimal) → FFFF D8F0 Hex (32-bit 2's complement) →
FF D8F0 Hex (24-bit 2's complement)
