RMC150 Register Map - File 41-42 Indirect Data

RMC150 Registers, Files 41-42: Indirect Data Map Registers

Use the Indirect Data Map Editor to edit the Indirect Data Map. The RMC150 Indirect Data Map includes 256 registers.

TheIndirect Data Mapregisters are the registers that should be accessed at runtime by a PLC when reading or writing theIndirect Data. The Indirect Data MapDefinition contains the addresses of the referenced registers, not the data. Reading or writing to these registers will not access the Indirect Data via a PLC.

Tip:
For the DF1/CSP addressing format, all 'F' type registers (32-bit floating point) can also be read as 'L' type (32-bit word) registers. This is very useful when reading registers with DWORD or DINT external data types

*The access and data types of the Indirect Data Values registers are determined by the mapped registers.

Note:
For the Modbus and FINS protocols, the Indirect Data and Indirect Data Map registers are duplicated in a lower address area for PLCs that cannot access a wide range of registers. See the Modbus Addressing and FINS Addressing topics for details.
