9 Register Reference
RMC150 Registers, Files 56-59, 72-75: Variables Registers
All variable registers are Read/Write.
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 variables defined as
DWORD or DINT data types.

Allen-Bradley DF1 and CSP
Where allowed by the host controller's communications, all the current values of the
variables can also be addressed as F56:n, up to n = 1023.
Modbus/TCP and /RTU
The address of the current value of variable n is 28673 + 2 x n.
FINS
The address of the current value of variable n is D28672 + 2 x n.
Note:
For the Modbus and FINS protocols, the command 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.
Tag Names
Tag names are given to registers to be used when accessing the registers from within
RMCTools. Tag names make the project easy to read.
