Drive Cliq is yet another that Siemens is using with their Sinamics drives. http://www.automation.siemens.com/mcms/infocenter/dokumentencenter/mc/Documentsu20Brochures/6fc5095-0aa83-0bp0.pdf I thought they would have used Profinet, but there must be some speed advantages to using Drive Cliq instead.
