through the text below which defines the column

headers used.

Assembly Definition Addresses

- Fixed addresses used to define the parameter

that will be stored in the "Working Addresses",

which may also be referred to as a pointer. The

value stored in these addresses will reflect (point

to) the Modbus address of a parameter within the

RM control.

Assembly Working Addresses

- Fixed addresses directly related to their associ-

ated "Assembly Definition Addresses" (i.e., As-

sembly Working Addresses 200 & 201 will as-

sume the parameter pointed to by Assembly Defi-

nition Addresses 40 & 41).

When the Modbus address of a target parameter is

stored in an "Assembly Definition Address" its cor-

responding working address will return that parame-

ter’s actual value. If it’s a writable parameter, writing

to its working register will change the parameter’s

actual value.

As an example, Modbus registers 726 and 727

contain the Limit 1 High Set Point (See Operations

Page, Limit Menu). If the value 726 and 727 is loaded

into Assembly Definition Address 110 and 111 respec-

tively (by default these registers are configured as

Alarm 8 State), the Limit 1 High Set Point will now

be stored in Modbus registers 270 and 271.

The table (See Appendix: Modbus Programmable

Memory Blocks) identified as "Assembly Definition

Addresses and Assembly Working Addresses" reflects

the assemblies and their associated addresses.
