9.1.2 Update Manager for Applications with Overhead Conveyor
Function
The Update Manager program allows you to automatically download a selected
STEP 7 program (including the system data and all the blocks) to selected vehicles in
an overhead conveyor system. When doing this, the head-end (plant control) of the
automation system transfers the PROFIBUS address of the target station (vehicle) to
the application, which then carries out the download to the stated station (vehicle).
Fig. 34: Plant overview
In this connection, the head-end communicates with the application via OPC. When
doing this, the application accesses the data of the SIMATIC NET OPC server as an
OPC client. Downloading is carried out controlled by the S7 command interface by
means of routing via the plant's head-end directly into the overhead conveyor
system's vehicle.
Advantages for users
•
Completely automatic updating of the vehicles' software in the case of changes
•
No need for staff members to be involved during updating
•
All vehicles are considered during updating; vehicles can no longer be
"forgotten"..
Since the Update Manager is a sample application for using PROFIBUS functionality
in a plant Siemens AG offers users no warranty or support. You can download the
software and the user manual from the Siemens Customer Support on the Internet
under ID:xxxxxx.
