5.3 SLC 5/04 via 1761-NET-ENI
In this example, the system consists of a 1747-L541C (5/04 CPU, 16K Mem, OS401 Series C FRN 3-8) processor and a
1747-NT4 Thermocouple Input Module residing in slot #1. The SLC 5/04 is connected to EtherNet IP via a 1761-NET-ENI
(Ver. D, Rev. A, Firmware 3.21) Network Interface connected to Channel 0. The 1761-NET-ENI’s IP address is
192.168.1.125. The MW100’s IP address is 192.168.001.101. The 1747
-NT4 module’s four input channels are sent to the
MW100’s Communication Channels C01 thru C04. The 1747
-NT4’s channels are configured for ―Engineering Units‖ which
will result in an integer value with an implied decimal point (i.e. 66.8 = 668). The MW100’s Measurement Channels 001
thru 010 are being read and stored in 10 words starting with F8:0.
Data File ―N9:0‖ has been created for I/O Configuration Data.
When using processors that do not have a built in Ethernet port, communications to an EtherNet IP device is
accomplished by sending a message via DF1 serial protocol to the 1761-NET-ENI, which in turn re-routes the message in
a CIP format.
The 1761-NET-ENI Network Inteface is configured via Rockwell’s ―ENI Configuration Utility,‖ available from Rockwell’s
website. The same cable that is used to connect the 1761-NET-ENI to the SLC 5/04 can be used to connect the 1761-
NET-ENI to a PC’s 9-pin serial port.
1761-NET-ENI Configuration
Under the ―ENI IP Addr‖ tab, select the ENI Series (D), set the 232 Baud Rate (38400), set the 1761
-NET-ENI’s IP
address (192.168.001.125) and subnet mask (255.255.255.0). Uncheck ―Obtain via BootP‖ as this application utilizes a
fixed IP address. Then click on the ―Message Routing‖ tab.
