The various Automationdirect.com DL205/405 PLCs have different ranges of V-memory that can
be accessed via the Ethernet. The Ethernet-capable DL205/405 PLCs only support between
1280 and 15616 V-memory words and therefore cannot access 64K registers. For each block of
registers below, the DL205/405 PLC CPUs that support that block are listed under PLC Support.
Status Registers:
PLC Support: D2-240, D2-250, D4-430, D4-440, and D4-450
These registers can only be read; writes are ignored.
Note: V0-V177 may be displayed as TA0-TA177, called aliases. You can disable displaying
aliases by selecting the View menu in DirectSOFT32, Options menu item, Global tab, and
clearing the Display Aliases checkbox.
