The SCTMi functions as a passive NFC tag that can be read by a reading device such as a smart phone or tablet. With the NFC applications by Schmalz, the information is displayed using a mobile website in the browser, therefore an app is not required. The reading device must only have NFC activated and be connected to the internet. -
Page 28: Description Of Functions
The SCTMi primarily consists of the IO-Link bus module and between 2 and 16 ejectors. Depending on the function, it refers to the IO-Link bus module or the individual ejector. General SCTMi functions Independently of the ejectors, the SCTMi IO-Link bus module has the following functions: Device identification ... -

The deletable counters can be reset to 0 during operation via IO-Link using the appropriate system commands. The non-volatile storage of the counter statuses only occurs every 256 steps. That means that when the operating voltage is switched off, up to 255 steps of the counter are lost. 44 | EN www.schmalz.com 30.30.01.02629/00... -
