Variable	PLC variable	Address	Access	Data type	Description
Sensors (si=sensor index 0..120; 0=unassigned (new) sensor)
Index	si	10 * si + 0	RW	I16	Sensor index (si); when changed sensor will be moved to new index, but only if new space is empty
Status	th_status[si]	10 * si + 1	RO	I16	Temperature sensor status 0 = no sensor, 1 = OK, 2 = Error, no response
Temperature	th_temperature[si]	10 * si + 2	RO	I16	Measured temperature in 0.1 °C (234 = 23,4 °C)
Humidity	th_humidity[si]	10 * si + 3	RW	I16	Measured relative humidity in 0.1 %RH (654 = 65,4 %RH)
Alarm Temperature HI	th_temperature_alarm_hi[si]	10 * si + 4	RW	I16	Measured temperature over set high limit 0 = idle 1 = alarm
Alarm Temperature LO	th_temperature_alarm_lo[si]	10 * si + 5	RW	I16	Measured temperature below set low limit 0 = idle 1 = alarm
Alarm Humidity HI	th_humidity_alarm_hi[si]	10 * si + 6	RW	I16	Measured humidity over set high limit 0 = idle 1 = alarm
Alarm Humidity LO	th_humidity_alarm_lo[si]	10 * si + 7	RO	I16	Measured humidity below set low limit 0 = idle 1 = alarm
