3.2 Parameterization data (asynchronous objects)
It is not necessary that the COMBIVERT G6 has synchronized to the fieldbus cycle to
receive asynchronous requests and respond.
The parameter data are communicated via the handshaking shown in chapter
„Output
process data (manager => client)“ . The VARAN master has to write on to the area "acy-
clic request" at the DPM. The area "acyclic respond" is filled by the device with valid data
and can be read by the master.
The format of the subindex adressing is also described in chapter „Output process data
(manager => client)“ .
examples of the byte Cmd/MsgID:
Initialisation:
0 0 1 1 1 1 1 1
(3Fh)
Read access:
0 0 0 1 0 0 0 0
(10h)
Write access:
0 0 1 0 0 0 0 1
(21h)
The number of successfull asynchronous communication accesses are shown in the
following parameters.
