18.2.6 Locating a Variable or I/O Address
The Locate command can be used to display the variable name
associated with an I/O address and display the I/O address
associated with a variable name. When you are locating a variable,
you have the option of finding the variable using a local I/O address
(slot, register) or a remote I/O address (slot, drop, slave slot, register).
The information will be retrieved from the configuration file stored in
the rack. Note that if you are using interface modules to
communicate with foreign I/O, you will not be able to use this
command to display Modbus, AutoMate, or AĆB register numbers.
This command will display Modbus, AutoMate, and AĆB registers
using the equivalent Multibus addresses.

If there are no variables mapped to the specified I/O point,
then the message There is no variable mapped to this
I/O" will be displayed.
Step 5. Enter the variable name.
If the variable is a boolean mapped to an I/O point, the
local I/O address (slot, register, bit) and remote I/O
address (slot, drop, slave slot, register, bit) will be
displayed.
If the variable is an integer, double, or real mapped to an
I/O point, the local I/O address (slot, register) and remote
I/O address (slot, drop, slave slot, register) will be
displayed.
If the variable is not in the rack configuration, the message
Variable is either not found or is a LOCAL variable" will be
displayed.
If the variable is mapped to a memory location, the
message Variable is a common memory variable. No I/O
address is available" will be displayed.
