* 1 : The total number of bytes becomes multiple of four, which is adjusted by the system.
* 2 : The number of bytes becomes multiple of four, which is adjusted by the system.
* 3 : 148 is the default value. (It can be increased or decreased by parameter setting.)
* 4 : Round up "number of bit device points/16" to the right of the decimal point.
* 5 : For the Universal model QCPU whose first 5 digits of the serial number are "10011" or earlier, it
will be the number of executing programs.
Remark
Refer to Section 5.4.4 for the memory capacity calculation example.
Table5.16 Memory capacity calculation for files (Universal model QCPU) (Continued)
Function Rough file capacity (unit: byte)
Sampling trace file
362 + (number of word device points + number of bit device points) 12 + (N1 +N2 + N3 +
number of word device points 2 + (number of bit device points/16) 2) number of traces (total
number of traces)
*4
• The following values are added to the N1 to N3 corresponding to the items set in trace
Additional information of trace condition settings screen. ( Section 6.14 (4)(b))
N1 : Add "4" at setting time
N2 : Add "10" at setting step No.
N3 : Add "8" at setting program name
File for device data
backup
Value set at formatting (2 to 1024k)
Local device
70 + 6 (set device type) + (2 ((total number of M and V points)/16 + (number of D points)
+18 (total number of T, ST and C points)/16)) (number of programs using local device)
*5
• M, V, D, T, ST and C indicate the following set devices.
M : Internal relay
V : Edge relay
D : Data register
T : Timer
ST : Retentive timer
C : Counter
