The RMC module has 64K (65536) 16-bit registers that can be read from or written to over
Ethernet, Serial, Modbus Plus, and PROFIBUS-DP. Each register is assigned an address.
However, under the different communication methods, different addressing schemes are used.
This topic describes using Allen-Bradley PLC addressing. For details on addressing from other
modules refer to the following topics:
• RMC Register Map (Automationdirect.com)
• RMC Register Map (Modbus/TCP and Modbus/RTU)
• RMC Register Map (Omron FINS)
• RMC Register Map (Siemens TI505)
• RMC Register Map (Siemens S7)
• RMC Register Map (Modbus Plus)
• RMC Register Map (PROFIBUS-DP Message Mode)
Allen-Bradley offers several Ethernet and serial solutions for its ControlLogix, SLC, PLC-5, and
SoftLogix 5 controllers. In addition, SoftPLC emulates the PLC-5 and therefore also uses Allen-
Bradley's Ethernet protocol. Over this protocol, the RMC's registers are broken into a number of
integer files. Each integer file used (N7, N9-N18, L19, N20-N255) is configured to be the
maximum size allowed on a SLC 5/05 file: 256 elements: Nf:0-255. For details on reading and
writing these registers, see the following topics:
• Using Allen-Bradley Controllers with the RMC ENET
• Using SoftPLC's SoftPLC with the RMC ENET
• Using DF1 (Full- and Half-Duplex) with the RMC SERIAL
Status Registers:
These registers can only be read; writes are ignored.
