PNOZ m ES Powerlink
4.5.1
Service Data Objects (SDOs)
All the relevant device parameters and current process data of the Ethernet POWERLINK
are entered in the object directory of the PNOZmulti 2. These can be read and written via
Service Data Objects (SDOs).
To enable the fieldbus module to be incorporated easily within a Ethernet POWERLINK
network, the object directory is available as an XDD file. The content is described in the
chapter entitled
.
4.5.2
Service data
The service data for Ethernet POWERLINK is divided into the following data areas:
}
Process data Base unit and expansion modules
}
Process data Fieldbus module and communication module
}
Diagnostic words
}
Enable elements
}
Project data
}
Device data
The content of the service data and addressing are described in the chapter entitled
.
4.5.3
Process Data Objects (PDOs)
A PDO can be assembled individually from the SDOs.
Maximum size for the PDOs:
}
254 Bytes input data
}
32 Bytes output data
The inputs and outputs are viewed from the Managing Node.
4.6
PNOZ m ES Profinet
4.6.1
Cyclical input and output data
Virtual inputs and outputs can be requested or set directly via the following modules. Each
element can be selected individually in the master control system, e.g. virtual inputs i031.
The data width is also established this way.
Input data
The Master writes to the virtual inputs of the PNOZmulti 2.
