Input Word Functions
Word Bit
Wd m 00 to 15
Wd m+1 00 to 15
Note A priority exists for setting and reading commands. If a bit with a higher prior-
ity always comes first, other settings and readings will not be made, even if
they have been specified. In order of decreasing priority:
1. Count value setting
4. Count value reading
Reading Count Value
While the Count Value Reading Bit (word n+2, bit 06) is ON, the value will be constantly read and stored
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
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.
BCD (Data Code Switching Bit OFF)
Word n+1
The output conditions will be stored with 3 bits.
000: Present value
Not 000: Present value
(Whether output is actually made depends on the settings of
the External Output Enable Bits, word n+2 bits 08, 09)
The sign will be stored
with 1 bit.
0: Positive
1: Negative
Hexadecimal (Data Code Switching Bit ON)
Word n+1
The output conditions will be stored with 3 bits.
000: Present value Set value
Not 000: Present value Set value
(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
