SEND/RECEIVE
The SEND/RECEIVE interface allows the program-controlled com-
munication to any partner station via a configured connection. Here the
data transfer happens by a call from your user application. The FC5 and
FC6 that are part of the VIPA block library are serving as interface.
This enables your control to send messages depending on process events.
FETCH/WRITE PASSIVE
With the help of FETCH/WRITE services partner systems have the direct
access to memory areas of the CPU. These are "passive" communication
connections that have to be configured. The connections are "actively"
established by the connection partner (e.g. Siemens-S5).
FETCH PASSIVE (request data)
FETCH allows a partner system to request data.
WRITE PASSIVE (write data)
This allows a partner system to write data in the data area of the CPU.
Here every configured connections of this station and its partner are
displayed. These data are information and may not be changed.
Note!
By appropriate shift respectively delete activities in the Siemens SIMATIC
manager connections may lose the allocation to the CP.
These connections are marked with "!" at ID of the overview.
