The following diagram shows the internal structure of the CPU Board.
The program reads and writes data in this memory area during execution.
Part of the I/O memory contains the bits that reflect the status of the PC’s
inputs and outputs. Parts of the I/O memory are cleared when the power is
turned ON and other parts are retained.
This is the program written by the user. The CPM2B-S executes the program
cyclically. (Refer to 1-3-5 Cyclic Operation and Interrupts for details.)
The program can be divided broadly into two parts: the “main program” that is
executed cyclically and the “interrupt programs” that are executed only when
the corresponding interrupt is generated.
The PC Setup contains various startup and operating parameters. The PC
Setup parameters can be changed from a Programming Device only; they
cannot be changed from the program.
Some parameters are accessed only when PC’s power supply is turned on
and others are accessed regularly while the power is on. It will be necessary
to turn the power off and then on again to enable a new setting if the parame-
ter is accessed only when the power is turned on.
The Communications Switches (Dip Switch Pin 1 to 3) determine whether the
peripheral port and RS-232C port operate with the standard communications
