Mechanical adjustment of sensors and actuators used to be commonplace for those operating IPCs and industrial control systems. Siemens IO Link allows parameters for the production and processing of different product variants and batches to be easily changed. This can even be done during runtime of the CPU and down to the sensor/actuator level. In addition, more convenient and much more detailed diagnostics are possible as well as remote diagnostics. Thus, matters needing maintenance attention such as dirty sensors can be detected before a failure occurs.
And now with the new IO-Link Master module, these benefits are available for the Siemens SIMATIC S7-1500 and Siemens SIMATIC ET 200MP. The 8-port IO-Link Master can be used both centrally directly after an S7-1500 CPU or remotely via an ET 200MP on PROFINET and PROFIBUS.
Diagnostic messages, warnings and IO-Link device outputs can be configured conveniently using the S7 Port Configuration Tool (S7-PCT) or directly in the TIA Portal. With its CM 8 x IO-Link, it can exchange up to 32 bytes per input and output data (240 bytes for the module as a whole) with only three connected conductors per port. This considerably reduces the amount of wiring required while boosting system availability through the use of pre-fabricated cables.
If an IO-Link sensor or actuator needs replacement, the configuration of the new device is automatically taken over by the IO-Link Master. This feature eliminates the need for manual setting and repeated configuration of sensor data or configuration using a separate tool. It also speeds the replacement process considerably. The IO-Link Master can even be exchanged without loss of data by saving the configurations and parameters stored in the Master onto the CPU.
