Object
"MOVILINK
®
cyclic
parameter
channel"
This object is 8 bytes long and contains the cyclic MOVILINK
®
parameter channel. All
MOVILINK
®
communication services can be performed by cyclically alternating reading
and writing of this object. The communications service is performed only with the change
of the handshake bit in the management byte. The MOVILINK
®
parameter channel
allows for access to all indices and, therefore, also to the IPOS
plus®
variable and
program memory.
The following table shows the structure of this communications object. Refer to the
MOVIDRIVE
®
"Fieldbus Unit Profile and Parameter List" documentation for information
about the structure of the parameter channel.
The "MOVILINK
®
parameter channel cyclical" object is only handled locally on the
INTERBUS interface.
The following table shows the process of a parameter access via the cyclic MOVILINK
®
parameter channel. The inverter will only start executing the service when the master
has changed the handshake bit in the parameter channel. To do this, the master must
read the parameter channel at the beginning of parameterization to obtain the current
status of the handshake bit in the inverter. The master can now initiate the evaluation of
the parameter channel in the inverter by changing the handshake bit.
