Chapter

Peer-to-Peer Messaging

This chapter describes messaging between the ENI and DF1 devices.

The following topics are covered:

• Messaging Between the ENI and DF1 Devices

• Message to Configuration Nodes (Nodes 100 to 149)

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

Messaging Between the

ENI and DF1 Devices

The ENI can route a DF1 message received from the attached

controller to a compatible destination TCP/IP device.

This is accomplished by using DF1 node addresses 0 through 49. ENI

Node addresses 100 through 149 store TCP/IP destination addresses.

When the ENI 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 Configuration Utility, or you can send a 485CIF message to each

node as described in this section.
