Description Product overview SIWAREX WP231 is a versatile and flexible weighing module that can be operated as a non- automatic weighing instrument. The electronic weighing system can be used in SIMATIC S7-1200 and uses all features of a modern automation system, such as integrated communication, operation and monitoring, the diagnostic system as well as the configuration tools in the TIA Portal.
The electronic weighing system described here is the perfect solution for applications in which signals from weighing or force sensors are to be acquired and processed. The SIWAREX WP231 is a very accurate electronic weighing system. The SIWAREX WP231 is equipped for the following applications: ●...
SIMATIC modules. You can create customized or industry-specific solutions in no time with the help of the configuration package available under the "Ready for use" application for SIMATIC. Figure 3-1 System overview SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
The scope of delivery only includes the SIWAREX WP231 weighing module. Note We recommend that you use the SIWAREX WP231 configuration package for configuring the SIWAREX WP231 electronic weighing system. The configuration package is not included in the scope of delivery of the module: → Accessories (Page 175).
The integration in SIMATIC gives you the option to process the weight value directly in the PLC (ProgrammabelLogic Controller). The SIWAREX WP231 is calibrated at the factory. This allows for automatic calibration of the scales without the need for calibration weights and replacement of modules without the need for recalibrating the scales.
The display of the current scale status can be configured. You can switch between several languages in the program. SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
All parameters can be assigned and the module put into operation using a SIMATIC HMI Panel connected to the S7-1200 CPU and the SIWAREX WP231 function and data blocks. The Ready-for-Use software is included in the scope of delivery of the configuration package.
● Interferences transported by communication cables ● Interferences having an effect via process cables ● Interferences entering the system via the power supply and/or protective ground Interferences can impair the fault-free functioning of the electronic weighing system. SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
● Always use shielded data cables. Always connect both ends of the data cable shielding to ground on a large area. ● Keep unshielded cable ends as short as possible. ● Always use metal/metalized connector housings only for shielded data cables. SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
Page 27
● Create a homogeneous reference potential and ground all electrical equipment. ● Use sufficiently dimensioned equipotential bonding conductors if potential differences exist or are expected between your system components. Equipotential bonding is absolutely mandatory for applications in hazardous areas. SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
The load cells, power supply and serial interfaces are connected via the screw-type connectors. Use of the WP231 in the SIMATIC TIA Portal is described in detail in cc 11 of this manual: → Integration in SIMATIC S7-1200 (Page 145) SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
(the load cells must be connected in parallel). If the distance of a load cell to the SIWAREX WP231 or the junction box is greater than the available length of the load cell connection cable, use the SIWAREX EB extension box.
Page 31
We recommended that you use the cables listed in chapter → Accessories (Page 175). 4. The shield must be connected to ground directly in the vicinity of the SIWAREX WP231. The maximum distance between the SIWAREX WP231 and the load cell applies when using the recommended cables.
Use only cables with protective braided shield (see recommended cables of digital load cells in chapter Accessories (Page 175)). Shielding density must be at least 80%. Figure 6-3 Shield connection element fitting (example) SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...

EIA-485 D- RS485 data line - for feeding in of bus signal If a SIWAREX WP231 module forms the termination of an RS485 network, insert wire jumpers between the D+‘ and T+ terminals and between the D-‘ and T- terminals for termination of the bus network.
Figure 6-6 Connection of Siebert display S102 The RS485 interface in the DR13 of the SIWAREX WP231 is set as follows: ● Baud rate: 9 600 bit/s ● Character parity: Even ● Number of data bits: 8 ●...
The following devices can be connected to the Ethernet interface: ● PC with SIWATOOL service and commissioning program ● Operator panels or other HMI devices with Ethernet and Modbus protocol TCP/IP ● Communication partner with Modbus protocol TCP/IP SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
6.11 Activation of write protection In the case of an officially verified SIWAREX WP231, write protection must be provided to prevent the changing of data relevant to the calibration. Insert a wire jumper between the module terminals P and PR for this purpose.
6.12 Mounting of the calibration protection plate In order to operate SIWAREX WP231 with verification capability, the load cell connections must be protected against manipulation. To achieve this, mount the calibration protection plate included in the calibration set as shown in the following picture. Subsequently secure the calibration protection plate using the associated terminals (see Figure 6-1 SIWAREX WP231 connection areas (Page 29)).
Parameters which can be entered in % or time are preset in such a way that they provide good results for most applications. With these default parameters, commissioning can be carried out in 5 minutes (see chapter Start (Page 45)). SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
● SIWATOOL The SIWATOOL program allows you to commission the scale without an Operator Panel and without an automation system. In the event of a fault, additional SIWATOOL diagnostics functions enable fast analysis of the cause. SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
Quick Start". You will be guided through the individual tasks for setting the most important parameters. The remaining parameters are factory-set in such a way that they can be used in most cases without any changes. Figure 7-1 Quick start step 1 SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
(except the Ethernet address and Modbus parameters). Service mode must be switched on first. Resetting to the standard parameters can then be carried out. Figure 7-2 Quick start step 2 SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
With both methods, make sure that the mechanical properties of the scale are flawless prior to calibration. SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
Note that the interval between the calibration weights must be at least 2% of the nominal load of the scale. With a 1 000 kg scale, a calibration weight of at least 20 kg must therefore be used. SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
Place "Calibration weight 2" defined in step 4 on the scale construction, and execute the "Set calibration weight 2" command. 4. Calibration of the scale is now complete. Return to the start screen by clicking on the house icon. SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
If the exact characteristic values are unknown, it is permissible to also use rounded-off numbers (e.g. 1.0 mV/V, 2.0 mV/V). The nominal load of an individual load cell (not the nominal load of the complete scale!) must subsequently be defined. SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
3. If a second known reference weight is available, place it on the scale in addition. Check whether the scale displays the sum of the reference weights. 4. Remove the reference weights from the scale. Check that the display is "0 kg" again. SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
The quick setup is based on the standard settings of the weighing module. Therefore, the standard parameter settings must be reset prior to the quick setup. Firstly, service mode is activated; the standard parameters are subsequently loaded using the "Load standard parameters (12)" command. SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...

The assignment of a new IP address to a SIWAREX module is necessary if several SIWAREX modules are present in one network. The following ports are used by SIWAREX: ● SIWATOOL port: 23006 ● MODBUS TCP/IP port: 502 ● TFTP for firmware download port: 69 SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
(Page 175). Install the program "Primary Setup Tool". When started, the program can determine the Siemens devices present in the network. The MAC (Media Access Control) address can be read on the front of the SIWAREX module. Every device has an MAC address which is unique worldwide.
If several parameters of the data record are to be changed, they are entered consecutively. The data record is subsequently selected in the tree view and sent to the SIWAREX modules using the right mouse button. Parameters are always changed as complete data records, rather than individually. SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
Excel and then processed further. The commands for starting and stopping are present in the "Trace commands" group (yellow memory card icon) in SIWATOOL. All important measured values, messages and changes in status are recorded. Figure 7-12 Trace export SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
3. Call the firmware download using the function key 4. Select the current firmware file under "Firmware Download". 5. Click the "Start transfer" button. Following the transfer, the SIWAREX module must be switched off and then on again. This activates the new firmware. SIWAREX WP231 Manual, 07/2014, A5E31238908A-02...
