DF1 Address Map

To access this map:
Expand the desired controller in the Project pane, double-clickAddress Maps, then choose DF1.

The DF1 Address Map lists the DF1 Addresses of all the externally-accessible registers in the RMC.

Browse the address map to find the DF1 address of any externally-accessible RMC register. If you are using an RMC200, you can add configurable address ranges to the DF1 Address Map. The DF1 addresses are all listed as F registers, but each register can also be accessed by external devices as L registers.

Using the Configurable Addresses

On the RMC200, use the configurable addresses if you need to access large blocks of RMC registers via DF1, and those registers are not already included in the fixed addresses (see DF1 Addressing) and do not fit in the Indirect Data Map.

If you need access to a few individual registers, use the Indirect Data Map instead. You need not configure DF1 addresses if you use the Indirect Data Map, since the Indirect Data Map already has DF1 addresses.

Adding DF1 Address Ranges

For the RMC200, you can add up to 128 configurable address blocks to the fixed address blocks.

In the bottom row, in the Start Address column, enter the first DF1 address you wish to use. Make sure the address conforms to the syntax described in Address Syntax below.
In the Registers column, enter the number of registers. This is the number of 32-bit registers in the RMC.
In the Map To column, enter the area in the RMC that this address range will apply to.
Repeat for additional address ranges. The rows will automatically re-order entries to keep them in numerical address order.

DF1 Address Syntax

DF1 addresses must conform to the following formats listed below. Address ranges as defined by the Start Address and End Address are not allowed to overlap.

Must start with an 'F' (32-bit floating point registers) or an 'L' (32-bit integer), followed by file number, a colon (:), and the element number.
The file number may be 0-4095, although most PLC's support only 7-255.
The element number may be 0-4095, although most PLC's support only 0-255.

Example Addresses: F40:0, L112:100
