Q46 Ethernet/IP Communications Manual

1.6

Interface Operation

Once the proper power is applied to the Q46 monitor, select "Ethr" in the ^Host

Comms listing of the OPTIONS menu on the Q46 to enable Ethernet/IP

functionality.

On power-up, the Q46 looks for a BOOTP server to assign an IP address.

Standard PLC networks (like Rockwell-RSLinx) include this server as part of the

system. If no response from BOOTP occurs after about 60 seconds, the Q46

system defaults to an IP address at 192.168.0.254. The data is stored in an

object with the attributes shown below, and can be acquired with an Ethernet/IP

PC test program using the explicit message format as follows –

Service: 14

Class: 4

Instance: 101

Attribute: 3

As an example, this call is shown in the Molex Ethernet/IP software tool screen

shot below, run on the default IP address of a Q46D. This free Molex PC tool

can be used to test explicit messages on the Q46 interface. To run this on a PC

for check-out, the user must first be sure to set the IP address of the PC Ethernet

port to the 192.168.0 subnet range, like 192.168.0.20 (or, manually run a BOOTP

server.) This tool cannot be used to set a fixed IP, and is primarily useful as

a quick verification tool.
