Configurations DIP switch for configuration method selection 4 4 Configurations 4.1 DIP switch for configuration method selection The sensor is a Modbus RTU (RS-485) slave device. It can be configured with a Modbus master when DIP2-Position 7 is OFF (default setting). The sensor has two sets of DIP switches: DIP1 and DIP2. It can be manually configured with DIP switches when DIP2-Position 7 is ON. For details, see DIP switch configuration [➙ 12]. 4.
4 Configurations Modbus registers NOTES: ● Register 764 (Modbus address) cannot be configured as 246 via a master. Address 246 is reserved for on-event addressing. ● Bus configuration command (768) is for on-event addressing only. 4.3 Modbus registers Holding Register (16-bit) No. Description Range Unit Scaling Default R/W 1 Temperature value -327…327 °C °C 0.01 - R -556.6…620.6 °F °F Temperature reliability 0 – No error - - - R 3 Relative humidity value 0…100 % % 0.

4 Configurations Push button configuration 4.5 Push button configuration When DIP2-Position 7 is OFF (default setting), push button function is activated. Push button The following can be operated via push button: ● On-event addressing ● Resetting the Modbus parameters to factory default settings 4.5.1 On-event addressing (ClimatixTM controllers configuration) On-event addressing is a rapid configuration approach working together with Siemens ClimatixTM controllers.
Configurations 4 Push button configuration NOTES: 1) The master cannot change the Modbus address (register 764) to 246. 2) The interval between every configuration command for register 764…768 from ClimatixTM is not more than 30 s. If it exceeds 30 s, the addressing mode ends automatically. 3) 10-minute countdown starts from entering addressing mode. 4.5.
4 Configurations DIP switch configuration 4.6 DIP switch configuration The Modbus setting can be configured via DIP switches when DIP2-position 7 is ON. NOTICE Modbus registers 764…768 are not writable via a master under DIP switches configuration. The sensor has two sets of DIP switches: DIP1 and DIP2.
