If more than 3 outputs are required in the application, then for each 3 additional outputs one sequencer add-on module "SQB_ChillSeqAddOn” must be connected to the main sequencer module. The total number of outputs which can be controlled by the combination of sequencer and sequencer add-on modules is 12.
The communication input channel ”CommInput“ and the communication output channel “CommOutput“ are used to transfer messages between the sequencer and sequencer add-on modules.
There are 2 ways to connect sequencer and sequencer add-on modules.
Fig. 13. Connecting sequencer add-on modules via daisy chain
The sequencer and sequencer add-on modules must be located in the same controller to ensure proper communication.
