RMC150 Registers, Files 56-59, 72-75, 88: 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.

* The data types of the variables are specified by the user when defining a variable in the Variable Table.

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.

The variables can given a user-defined tag name in the Variable Table Editor, which is the preferred method of referencing variables from within RMCTools. The user-defined variable name references the variable's Current Value.

Otherwise, each variable has a tag name as follows:

_VarTbl.CurVal[n] - Current Value of variable n.

_VarTbl.Initial[n] - Initial value of variable n.
