Internal Local Registers (Modbus Id 199) - Banner DXMR110-8K Instruction Manual

ONTROLLER ONNECTIONS FOR THE
The Ethernet connection supports the DXM Configuration Software, Modbus/TCP, PROFINET, and EtherNet/IP. ScriptBasic also has access to
Ethernet for custom programming. Use the software to configure the characteristics of the Ethernet connection, including the IP address. Any
parameters not changeable from the menu system are configurable from the configuration software.

4.3. Internal Local Registers (Modbus ID 199)

The main storage elements for the DXMR110-8K are its Local Registers, which can store 4-byte values that result from register mapping, action
rules or ScriptBasic commands.
For more information on the device registers and port settings of the DXMR110-8K IO-Link Master, refer to the DXMR110-8K IO-Link Master
IO-Link Register Map document (p/n 233478).
Local Registers updated from Modbus and Ethernet/IP transactions are restricted to a 16-bit data value to follow the standard Modbus Holding
Register definition.
The Local Registers defined in Action Rules must all be within the same register group. For example, an Action Rule cannot have inputs from an
integer group with the result register defined as a floating point register. To move between integers and floats, use the Register Copy Rule.

Local Registers 12001–12845, and 17001–19000 (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 DXMR110-8K, 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 12846–12850 (Reset, Unsigned)—These Local registers are reserved for use as Reset registers. A time interval can be spec-
ified 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 12851–12900 and 19001–20000 (Data Flash, Non-volatile, 32-bit, Unsigned)—The top 50 Local Registers are special
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 13001–17000—These Local Registers are paired together to store a 32-bit IEEE floating point format number in big endian
format. Registers 12001 [31:16], 12002 [15:0] store the first floating point value; registers 12003, 12004 store the second floating point number.
There are a total of 2000 floating point values; they are addressed as two 16-bit pieces to accommodate 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 DXMR110-8K 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 DXMR110-8K. 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 Registers into Local Registers space (12001–12850).

32-bit IEEE 754 floating point registers. Floating point values require two Local Registers to store a value. Floating
point Local Registers are referenced on the odd-numbered register addresses: 13001, 13003, and 13005. When
using Action Rules/Read Rules, always reference the odd-numbered register addresses.
