Loxone Examples - Modbus

Digital inputs example

Modbus polling cycle limitation

There is a minimum polling cycle of up to 0.1 seconds for 2 Modbus inputs per unit. The minimum polling cycle is 1 second for all other Modbus sensors.

Example of reading out state of dig. input no. 1

Insert new Modbus digital sensor with the settings IO address "208", Command "1", polling cycle "1"

Relay outputs example

Relay outputs limitation

• Max. permissible voltage at relay outputs is 230V AC
• Max. perm. load current is 7A at relay outputs no. 1,2,7,8
• Max. perm. load current is 4A at relay outputs no. 3,4,5,6,9,10,11,12

Example of settings for controlling relay output no. 1

Insert new Modbus digital actor with the settings IO address "0", Command "5", repeat cycle "5"

HSS/LSS outputs example

HSS/LSS outputs limitation

• Max. permissible voltage at V+ terminal is 24V DC
• Max. perm. load current is 2A per each channel

Example of settings for controlling HSS output no. "1" (HO1) as binary output

Insert new Modbus digital actor with the settings IO address "32", Command "5", repeat cycle "5"

Example of settings for controlling HSS output no. "1" (HO1) as PWM output

Insert new Modbus analog actor with the settings IO address "3", Command "16", data type "16-bit unsigned int"

Analog inputs/outputs example

Analog inputs/outputs limitation

• Max. permissible voltage at analog input terminal is 10V DC
• Max. perm. load current at analog. output terminal is 20 mA

Example of settings for sensing analog input no. "1" (AI1)

Insert new Modbus analog sensor with the settings IO address "16", Command "3", repeat cycle "5"

Example of settings for controlling analog output no. "1" (AO1)

Insert new Modbus analog actor with the settings IO address "11", Command "16", data type "16-bit unsigned int"

1-wire sensors example

Example of settings for sensing 1-wire sensor no. 1 temperature

Insert new Modbus analog sensor with the settings IO address "19", Command "3", data type "16-bit signed int"
