Establishing a Connection to the DDDT via EtherNet/IP
You can establish a read-only connection to the BMENOS0300 DDDT using either of the following EtherNet/IP connection types:
Establishing an Implicit Messaging Connection
You can establish an implicit messaging connection to the module using the following connection configuration information:
Sending an Explicit Message
You can use the CIP Assembly object of the BMENOS0300 module to send a one-time read-only explicit message to the module.
NOTE: You can send an explicit message to the Assembly object only when no other connections have been established that read from or write to this object.
The Assembly object includes the following attributes and services:
Reading the Response
The response of either an implicit or an explicit message consists of 16 hexadecimal byte values, with the least significant byte (0) on the left, and the most significant byte (15) on the right.
