GT1-CT01 Counter Unit
Section 5-4
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
→
2. Set value 2 setting
→
3. Set value 1 setting
→
4. Count value reading
→
5. Set value 2 reading
→
6. Set value 1 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
Word n
Sign
The sign will be stored in 1-digit hexadecimal.
0: Positive
1: Negative
Word n+1
Word n
Negative numbers will be stored using the 24-bit 2's complement
(the last 24 bits of the 32-bit 2's complement).

−
10,000

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.
