Product OVERVIEW
3 Product Overview
3.1
General
SIWAREX FTA (Flexible Technology, Automatic Weighing Instrument) is a
versatile and flexible weighing module which can be utilized wherever a scale
should fulfil its tasks automatically. Automatic scale operation is characterized by
an weighing procedure performed automatically according to a defined plan.
The SIWAREX MULTIFILL software supports parallel operation (bagging, filling,
loading) of several scales (up to 16) in one automation system. All the scales can
be operated by one operator with a control unit SIMATIC HMI e.g. TP170B. The
software is open and extensively commented so that the user can change, extend
and easily adapt the software to customers' wishes.
SIWAREX MULTISCALE software is provided for operation in batching plants or
mixers.
3.2
Benefits
SIWAREX MULTIFILL is characterized by a few clear advantages:
3.3
o
can be used for 2 to 16 scales
o
can be used for autarchic or networked scales
o
open and prepared for project-specific extensions
Application Range
SIWAREX MULTIFILL is the optimum solution wherever direct integration of the
weighing technology in the automation systems brings advantages. The weighing
is then a part of complex processes which are controlled by the automation
system. Calibratable weighing plants such as bagging plants, loading stations,
rotopackers can be set up at low cost with SIWAREX FTA and SIWAREX
MULTIFILL software.
Typical application ranges:
o
simultaneous filling of liquids at several points
o
simultaneous bagging at several points in the packing plant
o
simultaneous material loading at several loading stations

3.4
Typical configuration for SIWAREX MULTIFILL
Structure
The project is made up of two parts:
-
STEP7 software for the SIMATIC CPU
-
ProTool project (integrated in SIMATIC Manager)
Additionally the message system from the "Getting started" software package is
used. In this way the messages from SIWAREX FTA are displayed to the operator.
In this message system (FB1, FC1) the messages are generated on the basis of
ALARM S. Of course the customer can replace the message system with his own
message system.
3.5
Function
The control of the weighing procedure is completely run from the weighing module
as if in separately constructed weighing electronics. The integration in SIMATIC
enables the progress of the weighing procedure to be influenced directly from the
PLC program however. In this way you get a useful job distribution: the very fast
weighing functions are implemented in the SIWAREX module, the locks and signal
links in the PLC.
SIWAREX MULTIFILL takes over the jobs of a standardized routine in the
SIMATIC S7. In SIWAREX MULTIFILL the calls of the scale involved are

coordinated, the commands and setting values transferred to the scale according
to the process progress and the scale data are processed for visualization.

Commissioning- and Service with SIWATOOL FTA
SIWATOOL FTA is part of the scope of delivery of the configuration package
SIWAREX FTA for SIMATIC S7 (order number 7MH4900-2AK01). To perform
commissioning, the program must be installed on a PC first. The PC and
SIWAREX FTA are connected by the cable provided as an accessory.
Since SIWAREX MULTIFILL cannot set all the parameters of the SIWAREX FTA
initial commissioning of the scale is done with a PC and the SIWATOOL FTA
program.
The adjustment parameters (data record 3) can be changed later with the
SIWAREX MULTIFILL program and the scale can be readjusted.
The interface parameters (data record 7) can only be defaulted and the optional
MMC card only parameterized when commissioning with SIWATOOL FTA.
In dosing operation, the setpoint (data record 20) and the scale parameters for
every scale can be set individually or for all scales simultaneously.

Commands
5 Commands
5.1
Command Groups
The SIWAREX MULTIFILL software is parameterized for operating 6 scales.
Extension with an additional two scales is shown as an example in the form of
commented program sections. To extend the software to more than 8 scales, both
the program calls in the STEP7 program and the screens and variables must be
extended accordingly in ProTool.
5.2
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.
The Command Manager is called in OB1. The commands are given at different
places in the program:
-
by the operator at OP/TP with priority 2
-
by time OB35 with priority 3
Priority 1 is not occupied.

Call of FC Command Manager
Calls of n SIWAREX Scales
The calls of n scales are made using FC20. Command codes which are to be
executed by all scales are written directly from the OP/TP into the job slot CMD2 by
every scale. The command is not triggered directly but with the help of the variable
"DB_scale_INTERF".bo_scale_CMD
With this variable the trigger variable
S
"DB_scale_INTERF".bo_scale_CMD_ACCEPTED
is formed at the beginning of the FC20 which triggers the command codes
available on all scales.

U
"DB_scale_INTERF".bo_scale_CMD
// cmd from command button automatic mode
S
"DB_scale_INTERF".bo_scale_CMD_ACCEPTED
R

// cmd is accepted
// cmd from command button automatic mode
Forming the trigger variable for all scales
Before calling every scale, it is checked whether the scale is released for automatic
operation. In the as-delivered state the variable with which the command was
triggered was used for this purpose. Plant-side locks are used here in concrete
plants.

Alarms
Although the alarm programs from the free package "Getting started" (FB1 and
FC1) are not part of the SIWAREX MULTIFILL software they are used here for
generating messages from all used scales.
The alarms for the scale are decoded with the FC1 and passed onto the FB1 for
alarm generation with ALARM_S.
The alarm generation from the package "Getting started" is based on the
systematics of the ALARM_S components SFC18 and SFC19. In the scope
available here the scale alarms are monitored, the monitoring of the display word
IDW of the scale calls with the function block FB_SIWA is not integrated in the
"Getting started" package.
When using the "Getting Started" package it should be noted that no more alarms
can be generated by the system online after removing the display device e.g.
TP170B. After reconnecting the TP170B to the system, the SIMATIC-CPU must be
restarted in RUN.
Of course, the user can delete these program sections and use his own message
system.

Copying Parameters
Every scale can be parameterized individually. In addition the parameters of any
scale can be used as a master for other scales. The function FC21 copies the
parameters of a selected scale into the data blocks of all other scales and sends
them to the appropriate scales.

Configuring with ProTool
The software is configured for up to 8 scales. If it is to be extended for up to 16
scales this must be divided into two operating steps.
First the STEP7 program has to be extended. Other calls for the following scales
are added to the existing calls for 8 scales. According to the existing data blocks,
the data blocks must be created from the delivered UDTs for other scales. The
numbering of the data blocks is a continuation of the existing numbering scheme
for the first 8 scales.
The project ProTool must be extended in the second step.
The systematic structure of the screens for the first 8 scales must be continued in
the extension for further scales. The variables available for 8 scales must be
created for further scales.
The variables which are multiplexed can be used for further scales from the
beginning.
The project has been created for TP170B. When converting to TP/OP270 or 370
the saved weight output must be deleted and reconfigured
(Screen with calibratable weight output).
