6.1 Exclusive Owner
6.1.1 I/O Assemblies
As previously mentioned in section 2.3, EtherNet/IP Assemblies Overview, internal to the SST-
PB3-REM module, Profibus data is mapped to EtherNet/IP assemblies. In addition to I/O data,
the first 4 bytes of the I/O assemblies (not configuration) corresponding to the first Exclusive
Owner connection have a special meaning. When the module is configured as Master only or
Master/Slave the I/O assemblies corresponding to the first Exclusive Owner connection are 111
(input) and 121 (output). When the module operates in Slave only mode the I/O assemblies
corresponding to the first (and only) Exclusive Owner connection are 142 (input) and 152
(output). Note that when the module operates in Master or Master/Slave mode these 4 bytes are
also mapped in the master UDT provided by the SST™ Profibus Configuration Tool.
Primarily, the purpose of these bytes is to provide a command interface between the module and
the controller program. Some status information may also be retrieved via this interface.
The rest of the input (112, 113, 114, 141) and output (122, 123, 124, 151) assemblies contain
Profibus I/O data only.
