Integration
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 pro-
tocol. 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 program-
ming is performed with the aid of function blocks that are avail-
able for SIMATIC and SIMOTION.
The advantage of connecting SIMATIC MV420/440 to a commu-
nication module is that a uniform programming interface is avail-
able for a wide variety of PLC types and fieldbus systems. In ad-
dition, the complete cable portfolio for the communication
module interface is available.
At the same time as being connected via a communication mod-
ule 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.
