PRODUCT OVERVIEW
3 Product Overview
3.1 General
SIWAREX FTC (Flexible Technology Continuous Weighing) is a versatile and
flexible weighing module.
The function module (FM) SIWAREX FTC is integrated in SIMATIC and uses all
features of the modern automation system such as integrated communication,
diagnostics system and project configuration tools to its advantage.
The scale functionality of the SIWAREX FTC utilizes the following modes of
operation:
NSW/Non automatic weighing instrument in accordance with OIML R-76
Force measurement
Belt scale
Bulk flow measurement device
Loss-in-weight scale.
The functionality of belt scale is described in chapter 5. A separate manual is
available for other operating modes.
3.2 Advantages and Benefits
SIWAREX FTC is characterized by a few clear advantages:
oUniform structure and universal communication through the integration in the
SIMATIC S7 and SIMATIC PCS7
oStandardized configuration with SIMATC
oDirect application in the SIMATIC automation system
oApplication in the decentralized system concept through connection to
PROFIBUS-DP via ET 200M
oWeight measurement or force measurement to resolutions of 16 million parts
oCharacteristic curve linearisation
oHigh accuracy 3 x 6000d, legal-for-trade OIML R76 (0,5 V pro e)
oHigh sample rate of 10 ms
oPID controller with extensive setting options (Loss-in-weight scale)
oIntegrated filter functions
oParameterizable function for inputs and outputs
oFlexible adaptation to different requirements with SIMATIC
SIWAREX FTC 3-5

oSimple parameter definition with the SIWATOOL FTC_B program through the
RS 232 interface
oExchange of module possible without readjusting the scales
oScale progress logging – extensive optimization capabilities
oIntrinsically safe load cell supply for Ex-Zone 1 (optional)
oApplication in Ex-Zone 2.
oExtensive monitoring and diagnostics functions
3.3 Application Range
SIWAREX FTC is the optimal solution wherever weighing technology requires high
speed and accuracy. Because of the high resolution (3 x 6000 d, legal-for-trade or
16 million parts internally), scales can be built to work accurately over broad areas.
SIWAREX FTC can be used for creating container scales, platform scales, force
measurement devices, belt scales, loss-in-weight scales and bulk flow
measurement devices.
3.4 Structure
SIWAREX FTC is a function module (FM) of the SIMATIC S7-300 and can be read
directly on the SIMATIC S7-300 or ET 200M bus. Installation / cabling efforts for
the 80 mm wide module is simplified with the profile rail assembly (snap-in
technology).
Connection with the load cells is done using 40-pin standard front terminal strips,
the power supply is through a 2-pin plug and the serial interface is through a 9-pin
D-type plug connector.
Operation of the SIWAREX FTC in SIMATIC guarantees complete integration of
weighing technology in the automation system.
3.5 Function
The primary task of the SIWAREX FTC is highly accurate measurement of the
current weight and exact determination of the material quantity.
There are different weighing or measurement procedures, for which the SIWAREX
FTC can be optimally configured by defining parameters.
The following operating modes can be defined:
- Non Automatic Weighing Instrument – in accordance with OIML R-76
Instrument
- Force measurement
- Belt scale
- Loss-in-weight scale
- Bulk flow measurement device
3-6 SIWAREX FTC

PRODUCT OVERVIEW
SIWAREX FTC monitors and controls a number of functions during the weighing
procedures. The optimized system internal data exchange enables a direct
evaluation of weighing signals and states in the PLC program.
The weighing procedure influence on the PLC enables a flexible adaptation to the
system characteristics.
SIWAREX FTC is already adjusted in-house. Therefore, the scale can be adjusted
to theoretical settings without using any adjustment weights and modules can be
exchanged without readjusting the scale.
The SIWAREX FTC has two serial interfaces. The RS 485 interface is used for
connecting digital remote displays (for operation as a non-automatic weighing
instrument) or force compensation load cells WM, WMH from the Mettler Toledo
company. A PC can be connected to the RS 232 interface for setting SIWAREX
FTC parameters.
The SIWAREX FTC weigh module can also be used in explosion hazard areas
(Zone 2). An optional Ex interface SIWAREX IS provides load cells with an
intrinsically safe power supply for applications in zone 1.
3.6 System Integration in SIMATIC
SIWAREX FTC is completely integrated in the SIMATIC S7 and SIMATIC PCS7.
The user is absolutely free to configure his automation solution including the
weighing application as desired. The optimum solution can be created for small,
medium and large systems by selectively combining the SIMATIC components.
The configuration package and the SIWAREX FTC "Getting started" example
applications can be used for developing customer-specific or industry-specific
solutions quickly and efficiently. The following figure shows a typical setup for a
medium sized system.
For project planning with SIMATIC PCS 7 (only for belt scales), the completed
function block FB SIWA for the automation system and the graphic blocks for the
operator station are used.

3.7 Commissioning and Service with SIWATOOL FTC_B
For commissioning and for service, there is a special program - SIWATOOL
FTC_B for belt scales and Windows operating systems.
The program enables commissioning of the scale without having to understand
automation technology. During a service procedures, you can analyze the
processes in the scale and test them with the help of a PC. Reading the
diagnostics buffer from the SIWAREX FTC is very helpful in analyzing events.
Besides complete access to all parameters, memory or print-outs of the weighing
file, the program can create weighing curves as well.
