The I/O signal, buffer memory of the C intelligent function module can be set using the module label.
Module label configuration
A name of module label is defined in the configuration below:
"Instance name"_"Module number"."Label name"
"Instance name"_"Module number"."Label name"_D
Ex.
UP06_1.bIn_ModuleReady
■Instance name
The instance name of the C intelligent function module is "UP06".
■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 reflected to the module in batch at the time of
refresh. This shortens program execution time.
Direct access Values written to/read from a module label are immediately reflected to the module. Although the
program execution time is longer than refresh, the responsiveness will be increased.
