With IO-Link on the field level, the multitude of sensor interfaces can be reduced noticeably. Dissimilar interfaces on sensors become dispensable through the employment of a consistent IO-Link interface. It does not only simplify the variety of interfaces of sensors and IO-periphery, but also the variety of connecting cables required. Multipole-cables can be replaced with an unshielded standard cable. The complexity of wiring and installation can be reduced significantly through IO-Link.
