444 Communications InstructionsLocal Bridge AddressThis variable defines the bridge address on the local network. In theexample, DH-485 node 12 (MicroLogix 1400 on Link ID 1) is writing datato node 51 (SLC 5/04 on Link ID 100). The SLC 5/04 at node 17 is thebridge device.This variable sends the message to local node 17.Remote Bridge AddressThis variable defines the remote node address of the bridge device. In thisexample, the remote bridge address is set to zero, because the targetdevice, SLC 5/04 at node 63 (octal) is a remote-capable device. If thetarget device is remote-capable, the remote bridge address is not required.If the target device is not remote-capable (SLC 500, SLC 5/01, SLC 5/02,and MicroLogix 1000 Series A, B and C), the remote bridge address isrequired.Remote Station AddressThis variable is the final destination address of the message instruction. Inthis example, integer file 50 elements 0…4 of the SLC 5/04 on Link ID 100at node 63 (octal) receives data from the MicroLogix 1400 controller atnode 12 on Link ID 1.Remote Bridge Link IDThis variable is a user-assigned value that defines the remote network as anumber. This number must be used by any device initiating remotemessaging to that network. In the example, any controller on Link ID 1sending data to a device on Link ID 100 must use the remote bridge linkID of the passthru device. In this example, the SLC 5/04 on Link ID1,node 17 is the passthru device.Publication 1766-RM001A-EN-P - October 2008
