Hardware configuration of the electronic weighing system

The SIWAREX WP321 module can be found in the directory PLC/SIMATIC S7-
1200/technology modules/weighing modules of the hardware catalog.
The following basic properties of the module are defined during hardware configuration in the
TIA Portal. Note that the SIWAREX WP321 module is always completely in the process
image of the CPU.
● Installation location of the module
● Address in I/O area
● Diagnostics interrupts
● Hardware interrupts
● I&M (Identification & Maintenance) data
The electronic weighing system occupies 16 bytes in the input/output area.
Figure 11-1 Hardware configuration in the TIA Portal
TIA Portal automatically assigns a separate I/O start address and a HW ID for every
SIWAREX present in the project. These two parameters are relevant for calling the function
block, and can be obtained from the properties of the respective module.
