Station addressing

FactoryTalk Linx
 supports both local and remote station addressing.
Local station addressing
Channel
Station Address
Valid Entries
DH+
Physical station number
0-77 (octal)
DH-485
Physical station number
0-31 (decimal)
TCP/IP
Mapped station number, target IP address (host name)
www.xxx.yyy.zzz or an alias (a string of 1 to 8 characters)
Remote station addressing
Using
Allen-Bradley
 communication networks, applications can communicate with tags on remote
DH+
 or DH-485 networks when connected to:
  • a
    DH+
     network through a
    DH+
     card (1784-PKTX(D)). Remote
    DH+
     and DH-485 networks can be bridged by a 1785-KA5 interface module.
  • a TCP/IP network through an Ethernet port.
Note the following about station addressing:
  • The protocol for each network type is explicit messaging using Programmable Controller Communications Commands (PCCC).
  • MicroLogix
     devices use the same addressing as the
    SLC
     5/05E.
  • ControlLogix
     communicates using
    PLC-5
     addressing mode. To communicate with a
    ControlLogix
     controller, configure a
    ControlLogix
     mapping table to convert the
    PLC-5
     addresses to the appropriate messages. The DF1 driver communicates directly with the controller. The
    DH+
     driver communicates with the controller over a
    DH+
     bridge.
