IO-Link

Currently being expanded with IO Link Wireless to create an easily combinable wired/wireless network Limited extension Limited no. of slaves/components Low transmission speed Simple installation/ configuration Consistent device identification

Quick connection technology Limited extension Limited no. of slaves/components Low transmission speed, Simple installation/ configuration

Very high network extension with repeaters, Limitations in the no. of components Similar to Profibus DP, high transmission speed

Mitsubishi

Siemens, AS-Interface

IO-Link Konsortium, PNO

Widespread in Japan, Limited no. of com- ponents, high transmission speed

Very inexpensive, simple to install, limited extension, limited no. of components, low transmission speed

Simple configuration since there is no bus to configure, identity of component is detected, low transmission speed
