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.
