3.2.1 Asynchronous POWERLINK Data

data in a POWERLINK network that is not time critical

Note 1

Note 1 to entry: Within the POWERLINK cycle there is a specific period reserved for Asynchronous POWERLINK Data which is shared by all POWERLINK Devices. Each POWERLINK Device connected to the network can send asynchronous data by requesting it to the POWERLINK Managing Node. The POWERLINK Managing Node keeps a list of all asynchronous data requests and will subsequently grant the network access to one POWERLINK Device after the other.
