APPENDIX
Appendix 1
This section shows the module labels used to set the input/output signals and buffer memory of a high speed data logger
module.
Module label configuration
The name of a module label is defined in the following configurations:
"Instance name"_"Module number"."Label name"
"Instance name"_"Module number"."Label name"_D
Ex.
DL96_1.stIOSignal.bModuleReady
■Instance name
The instance name for high speed data logger module (RD81DL96) is "DL96".
■Module number
A module number is a number starting from 1, which is added to identify a module that has the same instance name.
■Label name
This is a module unique label name.
■_D
This indicates that the module label is for direct access. Without this symbol means a label for refresh. There are some
differences between refresh and direct access as shown below.
Type
Description
Refresh
Values written to/read from a module label are applied to a module in a batch at the time of
refresh. This shortens the program execution time.
Direct access
Values written to/read from a module label are immediately applied to a module. Although the
program execution time is longer than refresh, the responsiveness will be increased.
