The SIMATIC MV420/440 code readers have industry-standard PROFINET and communication module interfaces on the device. In addition, communications interfaces such as Ethernet and RS232 are directly available on the device.

Via the specified interfaces, the following communication services can be used:

Via the communication module interface, all communication modules can be used, e.g. for the PROFIBUS connection. The communication module interface is compatible with all available communication modules both electrically and with regard to protocol. Connection via a communication module makes it easy to switch between optical code reading with SIMATIC MV420/440 and RFID readers, simply by reconnection. The PLC programming is performed with the aid of function blocks that are available for SIMATIC and SIMOTION.

The advantage of connecting SIMATIC MV420/440 to a communication module is that a uniform programming interface is available for a wide variety of PLC types and fieldbus systems. In addition, the complete cable portfolio for the communication module interface is available.

At the same time as being connected via a communication module to the process (transmission of read result), the PROFINET interface on the device can also be used for a separate interface to HMI or a control desk.
