Data to Be Collected

This section describes the data to be collected by data logging.

Number of data points

The data logging function can collect up to 1280 data records. (10 settings  128 records)
*1 Duplicate data records are counted as distinct.

Data type

The following table shows the number of data records for each data type.
Data type
Bit
Word (signed)
Double word (signed)
Word (unsigned)
Double word (unsigned)
Single-precision real number
Double-precision real number
Time
*1
String
Numeric string
*1 The entered character code are output.
*2 The specified size can be 1 to 256. If the specified size is an odd number, the number of data records is rounded to the next higher
integer.
Example: The number of data records is 3 if the specified size is 5.
Data to be collected
Global device data can be collected.
Devices to be collected
The following table lists the devices that can be specified as the collected data.
Type Device
*2
Bit device X, DX, Y, DY, M, L, F, SM, V, B, SB, T (contact)
LST (contact)
*3
Word device T (current value), ST (current value), C (current value), D, SD, W, SW, RD, R, ZR, Z, FD, Un\G, Jn\W, Jn\SW, U3En\G, U3En\HG
Double-word device LT (current value), LST (current value), LC (current value), LZ
*1 An index modified device and indirectly specified device cannot be specified.
*2 For bit devices, digit specification is allowed for K1 to K8 only.
*3 For word devices, bit specification is allowed.
*4 To specify these devices with CPU Module Logging Configuration Tool, use T (contact): TS, T (coil): TC, ST (contact): STS, ST (coil):
STC, C (contact): CS, C (coil): CC, LT (contact): LTS, LT (coil): LTC, LST (contact): LSTS, LST (coil): LSTC, LC (contact): LCS, and LC
(coil): LCC.
*5 The device can be collected by using the CPU module where the SFC function can be used. ( Page 747 Added and Enhanced
