Module Labels

This section shows the module labels used to set the input/output signals and buffer memory of a camera recorder 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.
RC96C_1.stIOSignal.bModuleReady
■Instance name
The instance name of a camera recorder module (RD81RC96-CA) is 'RC96C.'
■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 label name unique to a module.
■_D
This indicates that the module label is for direct access. Without this symbol, the label is 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.
