The IO-Link devices are integrated using the standardized device description "IODD" which can be obtained from the relevant device manufacturer. S7-PCT supports both IODD versions 1.0 and V1.1.
All IO-Link devices available at Siemens are already included in the hardware selection catalog of S7-PCT.
S7-PCT is called up via the IO-Link master hardware configuration of STEP 7, but it can also be started in "standalone" mode if the IO-Link master is not operated on a SIMATIC controller or if no STEP 7 is used.
