4-22 ENI/ENIW Configuration (Nodes 241 to 254)
Node 241 - Ethernet Speed and Duplex Setting (Series D Only)
This node allows speed and duplex settings of 10 Mbps or 100 Mbps
and half-duplex or full-duplex to be forced. Auto negotiation may also
be selected with this node.
The ENI/ENIW performs the following Ethernet speed/duplex
configuration operations when receiving a 485CIF/PLC2 Unprotected
Write message of one element (integer) to Node 241.
• 0 = Auto Negotiate
• 1 = 10 Mbps half-duplex
• 2 = 10 Mbps full-duplex
• 3 = 100 Mbps half-duplex
• 4 = 100 Mbps full-duplex
Configuring ENI/ENIW Data
Parameters
This example illustrates how to configure the ENI/ENIW’s TCP/IP
address (Node 250).
1. Create an integer data file. Inside the file arrange your TCP/IP
data in groups of 4 words (as illustrated in file N50 below).
TIP
This procedure can also be used for any parameter
that requires integer numbers (nodes 50 to 150, 241,
244, 245, 250, 251, 252 and 253).
