Introduction EP6224-0092
The EP6224-0092 IO-Link module enables the connection of up to four IO-Link devices. These can be actuators, sensors or a combination of both. In addition, the EP6224-0092 offers four further digital inputs on the free pins of the M12 ports. Point-to-point connection between the box and the device.
The EL6224-0092 also supports TwinSAFE SC (TwinSAFE Single Channel). This enables the use of IO-Link data for safety-related tasks via EtherCAT.
The EtherCAT Box is parameterized via the EtherCAT Master. IO-Link is designed as an intelligent link between the fieldbus level and the sensor, wherein parameterization information can be exchanged bidirectionally via the IO-Link connection. The parameterization of the IO-Link devices with service data can take place from TwinCAT via ADS or, very conveniently, via the integrated IO-Link configuration tool. In the default setting, the four IO-Link channels of the EP6224-0092 operate as a 4-channel input module, 24 VDC, which if necessary communicates with connected IO-Link devices, parameterizes them and, if required, changes their operation mode. Each IO-Link port can also optionally be used just as an input or output. The slim design also enables use where space is cramped.
TwinSAFE SC
The TwinSAFE SC technology (TwinSAFE Single Channel) enables the use of standard signals for safety tasks in any networks of fieldbuses. The standard functionalities and features of the I/Os are retained. The data of the TwinSAFE SC I/Os are routed to the TwinSAFE logic and processed there in a multi-channel safety-related manner. In the Safety Logic the data originating from different sources are analyzed, checked for plausibility and submitted to a ‘voting’. This is done using certified function blocks such as Scale, Compare/Voting (1oo2, 2oo3, 3oo5), Limit, etc. For safety reasons, at least one of the data sources must be a TwinSAFE SC component. The remainder of the data can originate from other standard Bus Terminals, drive controllers or measuring transducers.
With the aid of the TwinSAFE SC technology it is typically possible to achieve a safety level equivalent to PL d/Cat. 3 in accordance with EN ISO 13849-1 or SIL 2 in accordance with EN 62061.
