Optimizing industry 4.0 communication architectures using multi-protocol I/O hubs and converters
performance (IP) demands of IP65, IP67, and IP68. The R45C series in-line converters and masters provide a gateway for connecting IO-Link devices to an IIoT network or system controllers using the Modbus RTU protocol. Model R45C-2K-MQ connects two IO-Link devices to a Modbus RTU interface. When analog signals are required, designers can turn to the R45C-MII- IIQ Modbus for a dual analog in-line I/O converter. Functions include: ■ Analog in. When the converter receives an analog input, it sends the numerical representation of the value to the corresponding Modbus register. It can accept analog inputs from 0 to 11,000 mV or 0 to 24,000 µA.

■ Analog out. The converter outputs an analog value corresponding to a numerical input. Analog outputs can range from 0 to 11,000 mV or 0 to 24,000 µA. ■ Process data values outside the valid range (POVR) can also be detected and processed, and the converter sends a signal to the system. When a single analog input needs to be converted to an IO-Link signal, designers can use the S15C- I-KQ. This cylindrical analog current to IO-Link converter connects to a 4 to 20 mA current source and outputs the corresponding value to an IO-Link master.
Banner offers a variety of Modbus RTU I/O blocks that support connections of multiple analog and discrete devices connected to a Modbus or IO-Link network. They can be mixed or matched to support flexible system designs and interoperability (Figure 5). Can wireless protocols be integrated? Banner’s Sure Cross DSX80 Performance wireless I/O network solution enables wireless connectivity. It can be used independently or connected to a host PLC using Modbus or a personal or tablet computer.
