V04000 – V04377 Non-Volatile Data Words V4000 – V4377
V40400 – V40423 Input Points X0 – X477 (16 per V-Memory word)
V40500 – V40523 Output Points Y0 – Y477 (16 per V-Memory word)
V40600 – V40617 Control Relays C0 – C377 (16 per V-Memory word)
V41000 – V41037 Stages S0 – S777 (16 per V-Memory word)
V41100 – V41107 Timer T0 – T177 Status Bits (16 per V-Memory word)
V41140 – V41147 Counter CT0 – CT177 Status Bits (16 per V-Memory word)
Important Note: The V-Memory word numbers in the above table are shown in octal. These numbers
must be converted to decimal before they are entered into the DN-3000 Configuration Software. For
example, if the DN-3000 is to access register V02000, the value 2000 in octal corresponds to the value
1024 in decimal. The value 1024 is then entered into the DN-3000 Configuration Software.
