Introduction AS-i data
40
Controllere devices with master profile M4 enable connection of slaves with more than 4 digital
inputs/outputs. The transmission is combined: part of the data transmission is carried out via the digital
bits D0...D3, another part via the "analogue" channels.
NOTE
The more data is transmitted, the longer it takes until all data of a slave has been transmitted.
Cycle time standard single slave = 5 ms
Cycle time standard A/B slave (if address is only assigned to A or B slave) = 5 ms
Cycle time standard A/B slave (if address is assigned to A and B slave) = 10 ms
The cycle time for CTT transmission (= combined transmission) is a multiple of these values for
individual data.
CTT = Combined Transaction Type
