Data Sampling in the PLC2 Memory
To perform data sampling in the PLC2 memory, the following settings are required.
• Temperature control network/PLC2Way table editing
• Buffering area setting
• Memory card setting (when [SRAM] or [CF Card] is selected for [Store Target] in the
[Buffering Area Setting] dialog)
• Trend sampling or data sampling setting (setting for displaying data stored in the
specified buffer)
1. Buffering area setting
Click [System Setting] → [Buffering Area Setting]. The [Buffering Area Setting] dialog is
opened.
[Sampling Method]
Temperature Control Net/PLC2
[No. of Table]
Select the temperature control network/PLC2Way table number for sampling.
[Sampling Time]
Specify the number of sampling times.
[Store Target] (Internal Buffer/SRAM/SF Card)
Choose the desired medium for storing sampling data.
Internal Buffer: Stores data in the internal buffer of the V7 series. (RAM)
SRAM: Stores data in the SRAM area. (SRAM mounted on the unit,
V7EM-S, REC-MCARD SRAM)
CF Card: Stores data in the CF card.
[Full Processing] (Continuous/Stop)
Choose the desired processing when the target medium space has been used up.
- Continuous: When [Sampling Time] has been exceeded, data from the oldest
is discarded.
- Stop: When [Sampling Time] has been exceeded, sampling is stopped.
