unsigned integer

Description

Note: Delta does not recommend using this command. PLCs can read any register directly

without needing to send this command. In a user program, use the Expression (113)

command to directly access registers.

This command copies the register pointed to by the Address into the axis' Read

Response register.

Specifying a Register Address

When issuing this command from anywhere other than RMCTools, the addresses in the

Address command parameter must be entered as an integer value.
RMC addresses are represented in IEC format as:

%MDfile.element, where file = file number, and element = element number.

Use the following equation to convert a register address to integer format, N:

N = file * 4096 + element

Example:
Register address %MD8.33 is 8*4096 + 33 = 32801.

Why Bother?

This command is used with certain communication types. If the communications is set up

to continuously return the Read Response register, then issuing this command will allow

you to read whatever register you want. This is a good way of accessing more registers

for communication types that are set up to only return certain registers.
