PLC
Programmable Logic Controller (PLC) modules are built
dynamically when selected from the menu. From a small
set of library symbols, hundreds of PLC modules can be
built on request. This method allows the module to
conform to the underlying ladder rung spacing, so you
can add spacers and break the module at insertion time.
