Adding the IF4U to CCW
The 2080sc-IF4U is configured for CCW (Connected Components
Workbench) using the PLUGIN_READ and PLUGIN_WRITE instructions
for generic plug-in modules.
The configuration, input data, and status structures discussed in the
sections above, are stored at different memory locations in the module.
The following table lists the memory location offset for each parameter
which is used when configuring the PLUGIN_READ, WRITE, and INFO
instructions.
