Special V-Memory Locations
The DL250-1 and DL260 CPUs have special V-memory locations assigned to each base slot
that greatly simplifies the programming requirements. These V-memory locations specify:
• the number of input and output channels to scan
• the storage locations for the input and output data
• the resolution for the inputs
• the range selections for the inputs and outputs
• the track and hold selections for the inputs
Module Configuration Registers
The following tables show the special V-memory used by the CPUs for the CPU base and
local expansion base I/O slots. Slot 0 is the module slot next to the CPU or D2-CM module.
Slot 1 is the module slot two places from the CPU or D2-CM, and so on. The CPU needs to
examine the pointer values at these locations only after a mode transition.
