DH+ Router Key Words
Keyword Description
LocalLinkID <dd> Local Link ID, 1 - 199
Eth <d.d.d.d> Ethernet Path Entry, followed by an IP address
PLCCSP <d.d.d.d> Endpoint of path is an older CSP Protocol PLC. Must be followed by an
IP address
Slot <d> BackPlane Slot Entry, slot range 0-255
PORT <d> <d> Manual CIP Port Path Entry, must be followed by exactly 2 parameters.
Each parameter has range 0-255
CLX Endpoint of path is a ControlLogix processor
PLC Endpoint of path is an Ethernet/IP PLC-5 or SLC
DHA Endpoint of path is channel A on a 1756-DHRIO
DHB Endpoint of path is channel B on a 1756-DHRIO
Keywords are not case sensitive.
The first entry in a path must be either Eth or PlcCsp.
If a path begins with Eth, the final entry in the path must be one of CLX, PLC, DHA or DHB.
If a path begins with PlcCsp, it must be followed by the IP address of the destination device and
nothing else.
Anything after a semicolon, either at the end of a line or on a line by itself, is treated as a
comment.
Examples:
In these examples, the AN-X is at IP address 192.168.1.12, Data Highway Plus station address 37
octal and local Link ID 121.
Example 1
1 Eth 192.168.1.65 Slot 1 CLX
The routing definition uses link ID 1. It routes messages from the AN-X across Ethernet to IP
address 192.168.1.65 (a 1756-ENBT), then to slot 1, which contains a ControlLogix processor.
Remote messages sent on Data Highway Plus to the AN-X using link ID 1 will use this path.
To send messages to a ControlLogix, you must first create a compatibility file using RSLogix
5000. Go offline, select Logic, then Map PLC/SLC messages. Enter a file number and the
associated ControlLogix tag.
