Memory Area of Omron CP1H PLCs

Memory area of PLC is the allocation of internal memory PLC that is accesible to be used as an operand of an instruction. Before learning the PLC programming technique. For PLC programmer, understanding the memory area of PLC is a must.

In this chapter, Omron CP1H is used as the example. This is fairly representative, due to the other series is similar. Likewisw for the other brands are basically the same principle.
In the memory area of Omron CP1H consists CIO area, Work area(W), Holding area(H), Auxiliary area(A), DM area(DM), Timer(T), Counter(C), Task flag area(TK), Data registers(DR), Index registers(IR), Condition flag area, and Clock pulse area.

Omron Modular PLCs Series

This type of Omron Modular PLCs is widely used as a machine control because It is middle PLC which is expandable both input-output and functions. It is flexible of Omron Sysmac with easy structure arranged on backplane. However, there are several PLCs are connected with backplane-free structure between CPU and modules so it is not necessary the backplane.

Unlike the model of Omron Micro PLCs, modules can be added as needed through a backplane or backplane-free structure.The modules could be positioning, analog, communication, counter, standard I/O and so on.
