8.2 Predened process data words
Process data are exchanged via cyclic data exchange between the network master and the
inverter.
De
tails
For the cyclic data exchange, the inverter is provided with 24 network registers.
•
12 network regist
ers are provided as input registers for data words from the network mas-
ter to the inverter.
•
12 network registers are provided as output registers for data words from the inverter to
the network master.
•
Each network register is provided with a corresponding code that denes which parameters
(or other data codes) are mapped t
o the network register.
•
The input and output registers are divided into three blocks (A, B, C) in each case, featuring
4 successive data words, respecvely:
Network register
Input register Output register
Network IN A0
Network IN A1
Network IN A2
Ne
twork IN A3
Network OUT A0
Network OUT A1
Network OUT A2
Network OUT A3
Network IN B0
Network IN B1
Network IN B2
Network IN B3
Network OUT B0
Network OUT B1
Network OUT B2
Network OUT B3
Network IN C0
Network IN C1
Network IN C2
Network IN C3
Network OUT C0
Network OUT C1
Network OUT C2
Network OUT C3
The terms "input" and "output" refer to the point of view of the inverter:
•
Input data are transmied by the ne
twork master and received by the inverter.
•
Output data are transmied by the inverter and received by the network master.
The exact assignment of the network registers and the number of data words
that can be transmied cyclically v
aries according to the network/communica-
on protocol. You can nd some detailed informaon in the documentaon for
the respecve communicaon protocol.
Data mapping
For establishing a simple network connecon, the inverter provides predened control and
status wor
ds for device prole CiA402, AC drive prole as well as in LECOM format. By means
of data mapping to a network register, each of these words can be transferred as process date
via network. Addionally, further mappable data words to individually control the inverter are
provided. The mappable data words are described in detail in the following subchapters.
Data mapping cannot be applied to all parameters. The mappable parameters
are marked correspondingly in the par
ameter aribute list. 4Parameter arib-
