2 Scope of Delivery
2.1 System Prerequisites
The project has been created for the following automation system:
- CPU 315-2 DP
- Touch Panel TP270 (Full version)
The project is made up of two parts:
- STEP7 Software for the CPU
- WinCC flexible Software for the Touch Panel TP270.
Both parts can set up again to be used with other devices:
- STEP7 Software with all CPUs from series S7-300 and S7-400 and a head ET
200M.
- WinCC flexible Software can be converted in the HMI devices which are
available in WinCC flexible.
The basic equipment is also required for the setup work – the configuration
package SIWAREX U for SIMATIC S7 (Order number 7MH4950-1AK01). This
configuration package consists of the following:
- SIWATOOL U Commissioning program for Windows
- Hardware Update (HSP) for the SIMATIC Manager hardware catalog
- Standard function block for operating the SIWAREX U in SIMATIC S7
(included in the project “Getting started”
- Device manuals in several languages
System prerequisites for using SIWAREX U “Getting started”:
- SIMATIC STEP7 Version 5.4 and higher
- WinCC flexible 2005 Version SP1 HF7 and higher
SIWAREX U 2-2
3 Overview
3.1 General
SIWAREX U (Compact Scale) is a versatile and flexible weighing module, which
can be used wherever static scales are to be used in the SIMATIC S7 automation
system or a force measurement is necessary.
The SIWAREX U function module (FM) takes full advantage of all the features of
the modern automation system, including the integrated communication, the
diagnostic system and the configuration tools.
The SIWAREX U “Getting started” software supports you in starting with
application setup. A scale can be controlled by the operator using a control unit
SIMATIC HMI e.g. TP270. The software is open and provided with commentary, so
that the user can change the software, expand it and easily modify it according to
customer wishes.
3.2 Benefits
SIWAREX U “Getting started” is characterized by a number of clear advantages:
o Complete solutions for a scale
o Open and prepared for project-specific extensions
o SIWAREX U – integrated messages through message bits
3.3 Application Range
SIWAREX U “Getting started” is the optimal solution anywhere that integrating
weighing technology directly into the automation system would be advantageous.
Weighing is then a component of complex processes which are controlled by the
automation system.
3.4 Structure
The project is made up of two parts:
- STEP7 software for the SIMATIC CPU
- WinCC flexible project (integrated in SIMATIC Manager)
Of course the message bits can be integrated into the customer's message
system.
SIWAREX U 3-3
3.5 Function
Weight measurement is run completely from the weighing module as if in
separately constructed weighing electronics. The integration in SIMATIC allows
weight values to be transferred directly into the PLC program. This way, there is
sensible task distribution: the weighing functions are performed in the SIWAREX-U
module, latching and signal linking is done in the PLC.
SIWAREX U “Getting started” takes over the tasks of a standardized program in
the SIMATIC S7. In SIWAREX U “Getting started”, the FB scales are called, the
commands and adjustment values are passed on to the scales corresponding with
the progress of the process and the data from the scales is prepared for the
visualization.

3.6 Commissioning- and Service with SIWATOOL U
SIWATOOL U is part of the scope of the delivery of the SIWAREX U configuration
package for SIMATIC S7 (Order number 7MH4950-1AK01). To perform
commissioning, the program must be installed on a PC first. The PC and
SIWAREX U are connected by the cable provided as an accessory.
Using the SIWAREX U “Getting started” program, the adjustment parameters and
limit values can be changed at a later time and the scale can be also be similarly
readjusted using a Touch Panel like with SIWATOOL U.

4 Operator Info
4.1 General
The description for the operator should describe the operation and monitoring of
the weighing installation. The description corresponds with the current status of the
SIWAREX U “Getting started” software. The descriptions for individual scale
parameters and scale functions can be found in the SIWAREX U and are not
explained individually in the display of the individual SIWAREX U “Getting started”
screens. All of the existing screens are shown in this product info.
4.2 Start Screen
The program starts with the scale view. The start screen can be replaced with
another image such as a customer logo.
4.3 Scale View
The operator of the scale can perform operations and monitoring from the Scale
View image. The weight is displayed in the centre of the screen. The explanation of
the function of the buttons is found in chapter: Meaning of the Function Keys
4.9.

5 Configuring
5.1 Command Groups
The SIWAREX U “Getting started” software is defined for operation with a scale.
5.2 Program installation in STEP7
You can find the SIWAREX U module in SIMATIC HW catalogue by the Function
Modules (FM) of SIMATIC S7 300 group.
If you can not find SIWAREX U in the SIMATIC Manager the SIWAREX U module
must first be inserted in the HW catalogue. Select the function "Install HW updates"
from the „Tools“ menu. Then select „Install from file“. The file for updating the
SIWAREX U module is located in the HSP_FOR_SIWAREX U directory of the
SIWAREX U configuration package for S7 (Order number 7MH4950-1AK01).
If you are using the same SIMATIC CPU, as in the project, you can simply load the
software from the project into the CPU. The program can be run immediately
afterward.
If you are using a different CPU, the hardware must be planned in the HW_Konfig
first. The current CPU must be deleted and replaced with the new CPU in this
case. When asked whether the program should also be deleted, enter "No".
Then transfer the program modules (FBs, FCs, OBs, DBs but not the SDB) to the
module folder in the new CPU.
5.3 Command Manager FC30
The commands of a scale are controlled by the appropriate function FC30. Using
function FC30 the commands can be executed on the scale by three different job
slots with different priorities.
CMD1 has the highest priority, CMD3 the lowest.
Calling the command manager is done in the OB1 in network 3. The commands
are actuated through various points in the program:
- by the operator at OP/TP with priority 2
- by time OB35 with priority 3
Priority 1 is not occupied.

The input variable s_Cmd_1 contains the command code and the control bits for
the command handling.
If FC30 is used as a command manager, the commands may not be transferred
directly to the SIWAREX by calling FB45, but through structure CMD1, CMD2,
CMD3.

5.5 Alarms
The message texts and help texts (German and English) are integrated in the
control unit.
Of course, the user can delete these program sections and use his own messag e
system.
5.6 Configuring with WinCC flexible
The software is for setup for showing a scale in TP270.
The conversion to other SIMATIC HMI devices is possible.
WinCC flexible offers a selection of target devices for the conversion.
5-16 SIWAREX U
5.7 Program installation in WinCC flexible
If you are using the planned CPU and TP270, the program is ready for operation
immediately after loading into the TP270 (or Start of Runtime in WinCC flexible).
When loading with the MPI interface, use MPI-address=1 for TP270, MPIaddress=2 for the CPU.
5.7.1 Setting up another CPU
If you are using another CPU, the project must be integrated into the new
environment.
With Netpro the CPU can be connected again. Then WinCC flexible should be
opened and under menu item Communication the connections as well as the tags
should be checked. If necessary, connections have to be reimplemented and tags
reconnected with the symbols.
In the last step, the project must be loaded to the target OP/TP.
5.7.2 Setting up another TP/OP
If another SIMATIC-HMI device is used, the project must be integrated into the new
environment. With the WinCC flexible Function “Change device type…” the
requested HMI device can be selected from a list.
