Local Registers Type Description
7001–8000 32-bit non-volatile integer Data flash, non-volatile
> 10000 Read-only virtual registers, system-level data
Local Registers 1–845 and 5001–7000 (Internal Processor Memory, 32-bit, Unsigned)—The Local Registers are the main
global pool of registers. Local Registers are used as basic storage registers and as the common data exchange mechanism.
External Modbus device registers can be read into the Local Registers or written from the Local Registers. The DXMR90-X1,
as a Modbus master device or a Modbus slave device, exchanges data using the Local Registers. Modbus over Ethernet
(Modbus/TCP) uses the Local Registers as the accessible register data.
Local Registers 846–849 (Reset, Unsigned)—These Local registers are reserved for use as Reset registers. A time interval
can be specified in the configuration software for the DXM to reset. If the data in the register does not change within the user-
specified time interval, the DXM resets.
Local Registers 851–900 and 7001–8000 (Data Flash, Non-volatile, 32-bit, Unsigned)—The top 50 Local Registers are spe-
cial non-volatile registers. The registers can store constants or calibration type data that must be maintained when power is
turned off. This register data is stored in a data flash component that has a limited write capability of 100,000 cycles, so these
registers should not be used as common memory registers that change frequently.
Local Registers 1001–5000—These Local Registers are paired together to store a 32-bit IEEE floating point format number in
big endian format. Registers 1001 [31:16], 1002 [15:0] store the first floating point value; registers 1003, 1004 store the sec-
ond floating point number. There are a total of 2000 floating point values; they are addressed as two 16-bit pieces to accom-
modate the Modbus protocol. Use these registers when reading/writing external devices that require Modbus registers in
floating point format. Since Modbus transactions are 16-bits, the protocol requires two registers to form a 32-bit floating point
number.
Virtual Registers —The DXMR90-X1 has a small pool of virtual registers that show internal variables of the main processor.
Some register values will be dependent upon the configuration settings of the DXMR90-X1. Do not use Read Rules to move
Virtual Local Registers data into Local Registers. Use the Action Rule > Register Copy function to move Virtual Local Regis-
ters into Local Registers space (1-850).
