Appendix A: System addressing
48 P/N 3102309-EN • REV 001 • ISS 18JUL19
Address format
EST4 addresses are in NNNCCCDDDD format, where:
• NNN is the node number. The node number is assigned when the installer downloads the CU database into
the control unit.
• CCC is the local rail module slot address. The node number and LRM slot address make up the LRM’s logical
address.
• DDDD is the device’s point address. The node number, LRM logical address, and LRM device point address
make up the device or circuit’s logical address.
Module addresses
Modules have a physical address and a logical address. The physical address identifies the card’s location in the
panel. The logical address identifies the card in the CPU database.
For a control unit with one node, see Figure 13 and Table 11 on page 49.
For a control unit with multiple nodes, see Figure 14 and Table 12 on page 50
