*3 [No. of samples] can be set up to 20.
*4 The following shows the method for roughly calculating the buffering duration from the buffering
capacity.
Buffering duration = (No. of executable bufferings)(Execution frequency [times/hour]) [h]
No. of executable bufferings = (Usage capacity)(SQL text length + Overhead (4 bytes) [cases]
SQL text length = Total field character length + 6 × No. of fields + Total data length + 20 [bytes]
[Calculation example]
Accessing to 256 fields with 1 job and 1 action and performing every 30 seconds when capacity:
64 M bytes, field name: 16 characters, data length: 32 characters
SQL text length = (16 × 256) + 6 × 256 + (32 × 256) + 20 = 13844 [bytes]
No. of executable bufferings = (64 × 1024 × 1024)(13844 + 4) 4846 [cases]
Buffering duration = 4846(6030 × 60) 40 [h]
