1 Application Areas and Usage

Automation Task To provide good comprehensibility, the features of the Micro Automation Set are explained using the example of an automation task.

In a packaging system, a check for completeness of the packaged goods is required before delivery. In the course of this quality assurance measure the goods are to be uniquely identified and all relevant data including time stamp are to be logged.

It is to be possible to import the log data to Office Excel. The automation of the logging process and the integration of the required components into the existing infrastructure of the packaging system are to be possible.

It must be possible to apply the check for completeness of the packaged goods also to other products with different content without extra work.

The packaging system is to be operated and maintained exclusively via an HMI device. Operation is to be possible in German and in English.

Automation Solution Set 6 The automation solution uses an S7-200 controller and the SIWAREX MS weighing module with single point load cell. The weight value of the packaged goods is captured and compared to a reference value. This enables to check whether all components are complete. The packages of goods can be uniquely identified via a batch number.

The integrated time of day function and the memory module of the S7-200 controller enable a logging of the currently measured weight values with time stamp. Interfacing the S7-200 controller to a Windows PC using the PPI cable enables an automatic readout of the log data. Alternatively to the PPI connection data can be transferred via Ethernet, PROFIBUS or the telephone network.

The recipe function of the S7-200 controller is used to manage the reference weight of different production series.

Using a TP 177micro touch panel the currently running packaging process can be monitored by screens providing German-English change language.

4 Function Principle

4.1 Capturing weight as measured variable and providing as value

Table 4-1

No. Function Comment

1. The SIWAREX R load cell SB series is used to convert a mechanical force into an electrical signal. Four expansion measuring strips (EMS) interconnected to a Wheatstone bridge are attached to the spring rod of the load cell.

2. If a force acts upon the spring rod and compresses or stretches the expansion measuring strips attached to it, an overall misalignment of the spring rod can be determined from the positive and negative changes in resistance. (Measurement voltage proportional to change in resistance)

3. With the aid of the analog-digital converter integrated in the SIWAREX MS weighing module, a weight value is continuously calculated from the measurement voltage.

4. This weight value is provided to the S7-

200 controller in the variable memory. The transferred value is a 16-bit integer value.

4.2 Identifying product and assessing quality by weight comparison

Table 4-2


5. For each product a unique identification number is read in e.g. by a bar code scanner. This product ID will later be used for tracking in the log data. After the product identification a subprogram for the quality assessment is started.

In this set, the product ID is generated in a subprogram.

6. The subprogram checks the weight value by comparison with two reference values: Weight reference value (optimum

product weight) Tolerance reference value (maximum

permissible deviation from the weight reference value expressed as a percentage)

If the real weight value of the product is in the tolerance range of the requirements, the quality of the current product is assessed as good.

7. After completing the quality inspection the result of the quality inspection is assigned to the product ID.

Quality status:

0 (poor) 1 (good)

ID: 2904 ? 2,3 kg ID: 2904 ? 2.3 kg

4.3 Logging the quality inspection

Table 4-3


1. In the framework of the configuration, the logging is prepared using the Data-Log wizard. The structure of the data to be logged

is configured: A data record includes 6 values (a total of 13 bytes)

A standard block for starting the logging with specified data structure is generated

1: Product ID (4 bytes) 2: Recipe ID (2 bytes) 3: Weight (2 bytes) 4: Tolerance expressed as a percentage (2 bytes) 5: Reference weight (2 bytes) 6: Product quality (1 byte)

2. The Data-Log standard block is called after completion of the quality inspection.

3. If the logging process is started, the

Data-Log standard block writes the current values of the data block into the 256 KB module. During each call a new data record is added to the already existing log data. Up to 1000 data records can be stored before the oldest record is overwritten. (Ring buffer)

The maximum number of data records to be stored on the memory module can be set using the Data-Log wizard

In addition, a date and time stamp are stored for each data record

4.4 Automated archiving of the log data

Archiving the log data Table 4-4


1. Via the S7-200 Explorer integrated in STEP 7-Micro/WIN the protocol data can be exported to the local hard disc of a Windows PC from the 256 Kbyte memory module and be saved as CSV file 2. Each archiving process generates a new file with the new current log data since the last archiving.

A data connection between S7-200 controller and a Windows PC is required.

2. The Scheduled Tasks standard function in MS Windows enables to automate the archiving of the log data via S7-200 Explorer at freely definable intervals. Record1Record2

Record3Record4

Record1Record2Record3Record4

Possible data connections between S7-200 and Windows PC Aside from the option of loading data from the S7-200 controller to a Windows PC via a PPI connection for archiving purposes described in this set, the following alternatives exist additionally:

4.5 Recipe Management

Table 4-6


1. In the framework of the configuration, the recipe management is prepared using the Recipe wizard. The recipe structure is generated: A

recipe contains two ingredients Two standard blocks for reading and

writing the recipes are generated

2. Five recipes are predefined and stored in the 256 KB memory module of the S7-200. They can be selected via two buttons on TP 177micro.

3. The recipes include the weight reference value of the product and the maximum deviation expressed as a percentage (tolerance).

4. Using TP 177micro the values of the predefined recipes can be edited. The recipe ID with the value 1 stands behind the selectable Recipe 1.

5. The two standard blocks RCP0_READ

and RCP0_WRITE for reading and writing the recipes in the 256 KB memory module always determine the recipe to be edited via the recipe ID.

5 Configuring the Startup Software

5.1 Preliminary Remarks

For the startup we offer you software examples with test code and test parameters as a download. The software examples support you during the first steps and tests with your Micro Automation Sets. They enable quick testing of hardware and software interfaces between the products described in the Micro Automation Sets.

The software examples are always assigned to the components used in the set and show their basic interaction. However, they are not real applications in the sense of technological problem solving with definable properties.

5.2 Download of the startup code

The software examples are available on the HTML page from which you downloaded this document. Table 5-1

No. File name Contents

2 Set06_WinCC_flex_V2d0_en.zip Archived WinCC flexible configuration for TP 177micro.

5.3 Configuring Components

Note At this point, it is assumed that the necessary software has been installed on your computer and that you are familiar with handling the software.

Note Regarding the configuration of the SIWAREX MS load cell only the

settings required for this micro set are displayed via the SIWATOOL MS, or have been realized in the Micro/WIN user program. If further parameter changes are to be performed, the device manual with Entry ID: 22600601 must be used.

Note If the S7-200 controller used is not an S7-224 XP (with integrated analog

inputs and outputs), then the addressing of the SIWAREX MS expansion module must be adjusted accordingly in the STEP 7-Micro/WIN project. (network 1 in OB1)

The actual addressing can be read via PLC / Information in STEP7 Micro/WIN.

5.3.5 SIWAREX MS weighing module

What has to be configured? Adapting the weighing module to the specific user case requires setting over 20 parameters in the SIWAREX MS module. The delivery of a new module comes with a factory setting, which meets the majority of the applications. Using a command, these factory settings can also be restored in retrospect. Adaptation to the application on hand requires performing the following configuration steps:

1. Restoring the factory settings The factory settings are available in the SIWAREX MS manual.

2. Define calibration parameters deviating from the factory settings. The individual elements are:

Characteristic value range The characteristic value range depends on the connected load cell. For a 6kg load cell a value of 4mV/V must be parameterized.

Calibration weight 1 Calibration weight, added to the scale during calibration. The calibration weight must be at least 5% of the rated load of all connected load cells. As a calibration weight you use an object familiar to you, whose exact weight you know.

Weighing range Each maximum weight which is generally not exceeded during regular weighing operation. Limit value signaling and the permissive limit of the tare input depend on the weighing range.

Decimal point for the remote display It is decisive for the interpretation of integer inputs of weight parameters. If 2 is specified (default value), then a calibration weight 1 of 2 kg must be input as value 200 for a value 2.00 (kg) to appear in SIWATOOLS MS or in a connected remote display, if the scale is loaded with 2 kg (correct zero point calibration assumed). The weight value transmitted to the PLC is 200 here and is independent of the configured decimal point.

Weight unit The (up to four) ASCII characters (e.g. g or kg ) are only used for the interpretation of the weight display in SIWATOOL MS or the remote display.

Configuration types The SIWAREX MS weighing module can be configured in two ways:

Configuration via the Step 7 user program using Micro/WIN Configuration via the SIWATOOL MS tool Configuration via Micro/WIN is only possible from product version 3 of the SIWAREX MS module. The product version: 03 is written on the right side of the module cover. Whether the configuration is possible via the Step 7 user program using parameter transfer can also be read out from the weighing module via the software.

The application on hand supports the configuration of the weighing module via the Micro/WIN user program and indicates at the TP 177micro whether the product version of the weighing module permits this.

As soon as all of the above configuration steps have been performed, and the Micro Automation Set is supplied with voltage and ready to operate, you select the Maintenance SIWAREX MS screen at the TP 177micro.

Figure 5-1: SIWAREX MS Firmware supports data record transfer to the PLC

As soon as the checkbox DS has been activated (black), your weighing module supports a mutual transfer of the parameter data records between the SIWAREX MS module and the S7-200 controller. In this case you do not require the SIWATOOL MS tool for the application. The scale configuration occurs controls at the TP 177micro.

Configuration via the Step 7 user program using Micro/WIN Prerequisite: The configuration steps up to those including chapter 5.3.3 were

performed;

SIWAREX MS product version 3; The Micro Automation Set is supplied with voltage.
