DH-485 Value 391
Specifying the Remote Element Directly
Selecting Specify Remote Addressing lets you directly specify the remote
element, rather than as a previously defined item. The DH-485 Value
dialog box replaces the DH-485 Remote scrolling list with a group of
Remote fields to be completed. As shown below, these are the same fields
that appear in the definition dialog box.
In the above example, the DH-485 Value block settings directly specify
file element N7:3 in the SLC at node 2. These direct settings produce
results identical to the indirect settings shown earlier.
Using Bit Masks
When you directly specify a remote element in a binary file, you can
select the Bit Mask option. The bit mask is a decimal representation of a
binary number that is bitwise “Anded” to the Binary DH-485 value.
