Scheduled Data with a ControlLogix
AN-X-PBSLV can exchange scheduled data with a ControlLogix
processor.
It supports:
• up to 248 registers of output data
• up to 250 registers of input data
• up to 250 registers of status input data
• RPIs from 5.0 to 3200.0 ms
The terms input and output are from the point of view of the
ControlLogix processor.
Mapping PROFIBUS Data
You select which PROFIBUS data is mapped to each of the
ControlLogix data areas.
The ControlLogix sends output data to the AN-X-PBSLV and the AN-X
sends it out on the PROFIBUS network, as PROFIBUS input data to a
PROFIBUS master.
The AN-X sends input data and status input data to the ControlLogix.
Connections
There are two possible types of scheduled connections from the
ControlLogix processor to the AN-X-PBSLV:
• Exclusive owner connections, which contain input, output and
possibly status input data
• Input-only connections, which contain input and possibly status input
data
Only the exclusive owner connection can write data to AN-X and to
PROFIBUS.
There can be only one exclusive owner connection to an AN-X module,
but there can be more than one input only connction to an AN-X.
You can have an input only connection even if there is no exclusive
owner connection. For example, you can use AN-X to monitor a
PROFIBUS network. If there are no active nodes, there is no need for an
exclusive owner connection, since there is no data to write.
Configuration
Configuring the scheduled data exchange consists of:
