Output Word Functions
Word Bit Function
Wd n 00 to 15
Wd n+1 00 to 15
Setting Count Value
At the rising edge of the Count Value Setting Bit (word n+2, bit 2) starts, the value is read and set.
BCD (Data Code Switching Bit OFF)
Word n+1 Word n
Sign
Set the sign in 1-digit hexadecimal.
0: Positive
1: Negative
Hexadecimal (Data Code Switching Bit ON)
Word n+1 Word n
When setting negative numbers, use the 24-bit 2's complement
(the last 24 bits of the 32-bit 2's complement).
Example:To set −10,000
−10,000 (decimal) → FFFF D8F0 Hex (32 bit 2's complement) →
FF D8F0 Hex (24 bit 2's complement)
Setting Set Values
At the rising edge of the Set Value 1 Setting Bit (word n+2, bit 0) or the Set Value 2 Setting Bit (word n+2,
bit 1) starts, the value is read and set.
BCD (Data Code Switching Bit OFF)
Word n+1 Word n
Set the output conditions 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)
Set the sign with 1 bit.
0: Positive
1: Negative
Hexadecimal (Data Code Switching Bit ON)
When setting negative numbers, use the 24-bit 2's complement
(the last 24 bits of the 32-bit 2's complement).
Example:To set -10,000
-10,000 (decimal) " FFFF D8F0 Hex (32-bit 2's complement) "
FF D8F0 Hex (24-bit 2's complement)
Set the output conditions 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)
