Industrial Identification with SIMATIC MV320 and MV340 via RF170C
Besides their function as USB input devices, the optical handheld readers SIMATIC MV320 and MV340 can also be operated using a SIMATIC PLC. Das RFID interface module SIMATIC RF170C (via ET 200pro) allows direct communication between the PLC and the optical handheld reader. The "SIMATIC Ident" standard blocks of the TIA Portal are intended for controlling the functions.
This application example explains how to configure the required modules and provides a function block that demonstrates how to use the SIMATIC Ident blocks for operating the handheld readers MV320 and MV340. You can use the function block directly or adapt it to further requirements.
