Chapter 10 Sampling
10-14
[No. of Words] (128 words maximum)
Specify the number of words to be sampled.
As many addresses as the specified number of words must be allocated.
When [Bit Sample] or [Relay Sample] is chosen for [Sampling Method], one
word corresponds to 16 bits.
[Sampling Time] (0 to 65535 sec)
Specify the desired interval for sampling. When “0” is specified for [Sampling
Time], sampling is made at every cycle. Set the desired interval in seconds
to perform sampling regularly.
[No. of Samples]
Specify the number of times for storing sampling data in the buffering area.
[Store Target]
Specify an address for storing sampled data.
•
Internal Buffer (Maximum capacity: 32 k words)
Sampled data is stored in the internal buffer within the V series. It is cleared
when the V series is in the STOP mode (the power is turned off, the Main
Menu screen is displayed).

1. Only the result up to 32 words is written to internal memory address $s177 to 435
(sample buffer word operation.)
2. When [Multi-link 2] or [Temp. CTRL/PLC2Way] is selected on the V606, a maximum
of 32 words is available only for alarm display.
Sampling at extremely short intervals (“0,” “1,” etc. is specified for [Sampling Time])
increases the number of PLC data reading times. Depending on screen data, the
processing speed of the V series may be slowed down. In this case, it is recommended
that the [
Memory Designation] option be unchecked. (Refer to page page 10-11.)
Specify a number greater than that of displayable lines that can be held in the display
area of sampling mode for [No. of Samples]. Otherwise, the linked switches (Roll-Up,
Reset, etc.) will become invalid.
