1.2 How It Works
SST-PB3-REM combines the functionality of an EtherNet/IP Adapter with that of a Profibus
Master or/and Slave which enables a controller acting as an EtherNet/IP Scanner to transmit and
receive data on the Profibus network.
There are four possible communication paths between the EtherNet/IP Scanner and the Adapter
embedded in the PB3 Remote Module:
•
Exclusive Owner connection(s) for I/O exchange.
•
Input-only connection for retrieving status information. When configuring an Exclusive
Owner connection in RSLogix5000 this connection is automatically opened when the
user selects Data SINT with Status for the “Comm Format” parameter.
•
Listen-only connection(s) for monitoring. Corresponding Exclusive Owner connection(s)
must exist.
•
Explicit Messaging for sending various commands, DP-V1 messaging and I/O exchange.
No implicit connection(s) is required.
The EtherNet/IP and Profibus scan cycles are independent from each other (see Figure 2.2-1
below).
