9. Register Reference
9.1. Registers
A register is a place in the RMC memory that stores data. The registers in the RMC are 32 bits
and are any of the following data types:
• REAL: 32-bit floating point
• DINT: 32-bit integer
• DWORD: 32-bit string of bits
Register Maps
RMC70 Register Map
RMC150 Register Map
The Register Maps list the addresses of all the registers in the RMC70 and RMC150.
Typically, you will need to use the register map to find addresses or registers when
setting up communications with the RMC from a host controller such as a PLC. The
register map also include links to detailed descriptions of each register.
Each register in the RMC can be addressed with several address types, such as Allen-
Bradley, Modbus, and Omron. Some register addresses are displayed in RMCTools, such
as in the Axis Tools, Indirect Data Map, and the Variable Table. To view those addresses
in various formats, right-click the address and choose Address Formats.
When referencing registers from within the RMC, such as in user programs, you do not
need to use an address. You can use tag names instead. Tag names are given in the topic
for each register.
Address Formats
For each register, the register map provides addresses in the formats listed below. The
address type you use will depend on the communication method you use. For more
details on the addressing formats, see the respective topics.
 IEC-61131 Addressing
 Allen-Bradley DF1 Addressing
 Modbus Addressing
 FINS Addressing

The Status Registers provide information on the status of each axis. These registers are not
editable; they are read-only. Each Register is a 32-bit word. The Status Registers are axis
