Integrating sensors to IO-Link The

The Simatic PX130C adapter from the Siemens Industry Automation Division makes it easier to integrate standard sensors into the IO-Link, the communication standard for the sensor/actuator level. With the device, the majority of sensor types available on the market can utilize the benefits of the IO-Link without any special modification, facilitating integration in the central diagnosis and detection of errors, for example.

The PX130C adapter enables connection of up to two binary proximity switches or a single analog sensor to the control level. The two inputs can be set to pnp or npn, one of which is digital, the other being either analog or digital. The analog input can be set to 0-20 mA, 4-20 mA or 0-10 V.

Signal conditioning functions include A/D conversion, rotational direction recognition, speed monitoring, input inversion, switching time measurement and timers with extended pulses. And diagnostic functions monitor connected sensors for wire breaks, short-circuits and overcurrent/undercurrent. Configuration takes place in the standard engineering tool using the supplied IODD (IO-Link Device Description).
