 Many engineers discover that copying the PLC's logic is easy. Matching the PLC's reliability is the hard part.

+This is one reason CUBLOC was originally developed.

+If you build a custom board using a CUBLOC module, some of these challenges become much easier to manage.
+Because CUBLOC uses ladder logic, you keep the PLC-style scan cycle and behavior that many industrial systems rely on. This helps avoid some of the software-related issues that can appear when a PLC is replaced with a conventional microcontroller program.
+Field maintenance is also easier. Logic changes can often be made without redesigning hardware or rewriting large portions of firmware.
+However, the hardware is still your responsibility.
+Noise protection, surge protection, PCB layout, grounding, and power supply design must still be done correctly. A CUBLOC module can simplify the control side of the design, but it cannot compensate for poor hardware design.
+If you have limited experience designing industrial control hardware, getting help from an experienced PCB designer can save a great deal of time and frustration later.
