Signal processing and communication module (CPU)

A signal-processing and communication module (CPU) are made up of a main circuit board for

processing (CP1M) and 'piggyback' circuit boards for communication modules (COM#1 to

COM#5). These circuit boards are designed for LAN, time synchronization and others. They

are mounted on the CPU main board by their connectors. Figure 5.3-1 shows a board

implementation example.

Note: The implementation of COM#1 to #5 may vary according to circumstances.

Signal processing

The operation of relay and control applications are achieved with the CPU on the CP1M board.

The CPU board has SDRAM, MRAM, and NOR-Flash; the NOR-Flash is used to store setting

data and recording data; the MRAM is used to store several counter values, etc. Both are of

non-volatile memory so that the stored data will be not be erased if the power is cut off.
