■Data type
The data type to sort the buffer memory area is given. Each data type is as follows:
Data type
stnMonitor1
stnMonitor2
stnControl
stnSetting
■Channel
The channel number corresponding to a module label is given. A numerical value of 0 to 7 is used to correspond to CH1 to
CH8.
(CH1: 0, CH2: 1, CH3: 2, CH4: 3, CH5: 4, CH6: 5, CH7: 6, CH8: 7)
■Data format
The string that represents the data size of a buffer memory area is given. Each data format is as follows:
Data format

ud
■Label name
The label identifier unique to a module is given.
■_D
This string indicates that the module label is for direct access. A module label without the string is for auto refresh. The
following table shows the differences between auto refresh and direct access.

Appendix 1 Module Label
Description
Values that are read from or written to the module label are reflected
in the module collectively at the time of auto refresh. This shortens
the program execution time. To use auto refresh, set "Target" to
Module Label in "Refresh settings" of "Module Parameter".
Values that are read from or written to the module label are reflected
in the module instantly. Compared with auto refresh, the program
execution time becomes longer. However, the responsiveness is
high.
