SFC 232 - FETCH
The FETCH block initializes a FETCH order in the partner station.
The FETCH order defines data source and destination and the data source
is transmitted to the partner station.
The CPU from VIPA realizes the definition of source and destination via a
pointer parameter.
The partner station provides the
Source data and transmits them via
SEND_ALL back to the requesting station. Via RECEIVE_ALL the data is
received and is stored in
Destination.
The update of the indicator word takes place via FETCH res. CONTROL.
The handshake for initializing FETCH is only started, if
• the FB VKE receives "1"
• the function has been released in the according CP indicator word
(order active = 0).
Note!
More information for indirect parameterization you will find in this chapter in
"Page frame communication - Source res. ".
