5.2 NFC
NFC (Near Field Communication) refers to a standard for wireless data transfer between different
devices over short distances.
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.
The reading distance is very short for NFC applications.
Find the position of the NFC antenna in the reading device used
For the optimum data connection between the reading device and the SCTMi, the reading device
should be aligned as parallel to the upper side of the SCTMi as possible and the reading device
antenna should be positioned toward the center of the SCTMi antenna.
When parameters of the SCTMi have to be changed via the IO-Link or NFC, it must be
ensured that the power supply of the switch then remains stable for at least 3 seconds.
Otherwise, it can result in data loss and the subsequent error E01.
Access to the SCTMi parameters via NFC also works when the supply voltage is not
connected.
