*1: If the value in D1200 is 0, and the value in D1201 is 4095, the DVP-20PM series motion controller used will
automatically skip M1000~M2999, and M0~M999 and M3000~M4095 will be changed to latching devices.

End: D1211 (K9999) *3
Some special data registers are latching data
registers. They can not be changed.
*2: K-1 indicates that the timers are no
n-latching devices.
*3: If the value in D1210 is 0, and the value in D1211 is 9999, the DVP-20PM series motion controller used will
automatically skip D1000~D2999, and D0~M999 and D3000~D9999 will be changed to latching devices.
 When power is switched ON/OFF, or when the DVP-20PM series motion controller used switches
between a manual mode and an automatic mode, the action of general devices are as shown below.

A DVP-20PM series motion controller performs operations on five types of values according to various
control purposes. The functions of the five types of values are described below.
1. Binary number (BIN)
The values on which a DVP-20PM series motion controller performs operations, and the values stored
in the DVP-20PM series motion controller are binary numbers. Binary numbers are described below.
Bit: A bit is the basic unit of information in the binary system. Its state is either 1 or 0.
Nibble: A nibble is composed of four consecutive bits (e.g. b3~b0). Nibbles can be used to
represent 0~9 in the decimal system, or 0~F in the hexadecimal system.
Byte: A byte is composed of two consecutive nibbles (i.e. 8 bits, b7~b0). Bytes can be used
to represent 00~FF in the hexadecimal system.
Word: A word is composed of two consecutive bytes (i.e. 16 bits, b15~b0). Words can be
used to represent 0000~FFFF in the hexadecimal system.
Double word: A double word is composed of two consecutive words (i.e. 32 bits, b31~b0). Double
words can be used to represent 00000000~FFFFFFFF in the hexadecimal system.
