Operands:
S
1
: Target time of valve (absolute position)
S
2
: Time from fully-closed to fully-open of valve
(destination)
D
: Startingoutput address
Description:
1.
S
1
occupies 3 consecutive registers.
S
1
+ 0 is for storing the designated value;
S
1
+ 1 is the
current position of the valve and
S
1
+ 2 is for storing the parameters recorded in the instruction
execution. DO NOT alter the last two registers.
2.
D
occupies 2 consecutive output addresses.
D
+ 0 is the “open” contact and
D
+ 1 is the
“closed” contact.
3. The unit of time: 0.1 seconds. When the scan time of the program exceeds 0.1 seconds, DO
NOT use this instruction to adjust the position of the valve.
4. Frequency of the output device: 10Hz.
5. When the time of
S
1
+ 0
>
the fully-opened time set in
S
2
,
D
+ 0 will remain On and
D
+ 1 will
remain Off. When the time of
S
1
+ 0
<
0,
D
+ 0 will remain Off and
D
+ 1 will remain On.
6. When the instruction is enabled, it will start to control the valve from “0” time position. If it cannot
be determined that the valve is at “0” before executing the instruction, be sure that
S
1
+ 0 is less
than 0 and execute the instruction for
S
2
(time) before sending in the correct target control time.
