Page 8: Network Structure Modbus Rtu
Every Modbus device address can only be allocated once within the same network. The Condair Omega or the Condair Delta SPA Control box always acts as a slave. In the master-slave principle, only the master (e.g., control computer) can initiate data transmission. The affected slave (Condair Omega or Condair Delta SPA Control box) responds to this and delivers the queried data to the master or performs the action requested by the master. -
Page 9: Connection And Configuration Of The Modbus Interface
To connect the Modbus interface, proceed as follows: 1. Switch off the Condair Delta SPA Control Box or the Condair Omega via the unit switch. Set the external electrical isolator(s) in the mains supply/supplies to "Off" and secure the electrical isolator(s) in the off position against unintentional switching on. - Page 10 5.

Page 12: Modbus Parameters
Modbus Parameters If a SPA control board is operated in system mode "Wellness Dual", 2 cabins can be controlled (dual cabin application for small cabins). In all other cases, only the parameters for cabin 1 are relevant and all parameters for the cabin 2 can be neglected. Note: For dual cabin application for medium size cabins, two SPA control boards are required, both of them must be connected to the Modbus network. - Page 13 Description Range Input/Holding Format Register 1-based Read with function 03 Write with function 16 Current time of day since mid- 0 – 86400 s 4128 night in seconds, e.g.: 10:00 = 10*3600 Current date in seconds based 0 – x s 4132 on reference date/time (ref- erence date: 01.01.2010).
