IO-Link provides the connectivity needed to gather the data necessary to optimize the performance of Industry 4.0 factories by connecting legacy and other edge devices with the main Ethernet IP, Modbus TCP/IP, or PROFINET network. It supports high levels of data availability, extended diagnostics, remote configuration, and simplified device replacement, speeding process and line changes using connectivity that is standardized in IEC 61131-9 with simple unshielded 3 or 5 wire standard cables defined in IEC 60974-5-2.

IO-Link hubs
When numerous sensors or actuators need to be connected to a single IO Master, designers can use an IO-Link hub to aggregate sensor and actuator signals and transmit them to an IO-Link master via a single cable. For example, the R90C-4B21-KQ features four input ports and connects to the master using a standard M12 connector (Figure 4). It’s a compact bimodal (PNP or NPN) to IO-Link device converter that connects discrete inputs and sends the value to an
n Discrete mirroring enables the signals (in and out) to be mirrored to any of the four ports n Discrete I/Os can be independently configured as NPN or PNP n Rugged over-molded IP68 rated design IO-Link signal converters Various types of converters are available for IO-Link networks to connect sensors and other devices that may use a range of signal types, such as discrete PNP or NPN signals, analog 0 to 10 VDC signals, and current transducers. Examples of IO-Link signal converters include: n R45C-K-IIQ IO-Link to analog current in or out converter (Figure 5) n R45C-K-UUQ converter for analog voltage in or out
n R45C-K-IQ converter for analog current out n R45C-K-UQ converter for analog voltage out IO-Link inline converters are also available that are about the size of a single AA battery. These converters can handle various signal types and convert them to IO-Link, Modbus, or other protocols. For example, the S15C- I-KQ is an analog current to IO-Link converter that connects to a 4 to 20 mA current source and outputs the value to an IO-Link master. The small size of these converters simplifies the addition of legacy sensors into networks with standard protocols for process or environmental monitoring. Their IP68 ratings enable them to be broadly deployed in industrial settings.
