Chapter

Peer-to-Peer Messaging

This chapter describes messaging between the ENI/ENIW and DF1

devices. The following topics are covered:

• Messaging Between the ENI/ENIW and DF1 Devices

• Message to Configuration Nodes (Nodes 100 to 149) and

Sending a Message to a Destination Controller (Nodes 0 to 49)

Messaging Between the

ENI/ENIW and DF1 Devices

The ENI/ENIW can route a DF1 message received from the attached

controller to a compatible destination TCP/IP device, using DF1 node

addresses 0 through 49. ENI/ENIW Node addresses 100 through 149

store TCP/IP destination addresses. When the ENI/ENIW receives a

write message to nodes 100 to 149, it stores the TCP/IP destination

address in the corresponding map register.

To configure the destination TCP/IP addresses, you can use either the

ENI/ENIW Configuration Utility, or you can send a 485CIF/PLC2

message to each node as described in this section.

The table below illustrates the relationship between messages and

their corresponding configuration addresses.
