Device circuit

Circuit is a unique identifier of a particular entity (input, output, or function) of each device. The circuit is created automatically during initialization of Evok according to the table below.

Circuit creation table:

Device type name	Key	Circuit format	Examples
Relay	ro	<device_name>_<number>	2_01, xS11_02
Digital Output	do	<device_name>_<number>	1_01, 1_02
Digital Input	di	<device_name>_<number>	1_01, xS11_02
Analog Output	ao	<device_name>_<number>	1_01, xS51_02
Analog Input	ai	<device_name>_<number>	1_01, xS51_02
User LED	led	<device_name>_<number>	1_01, 2_02
Master Watchdog	wd	<device_name>_<number>	1_01, 1_02
1-Wire bus	owbus	<device_name>	1
1-Wire power	owpower	<device_name>	1
Temp sensor	temp	<1-Wire_address>	2895DCD509000035
Non-volatile memory	nvsave	<device_name>	1, 2, xS51
Modbus slave	modbus_slave	<device_name>	1, 2, IAQ
Device info	device_info	<model_name> (grouped) / <device_name> (single)	L533, S167, xS51
Data point	data_point	<device_name>_<register_address>	IAQ_0, IAQ_6, IAQ_10
Modbus register	register	<device_name>_<register_address>	1_0, 1_1, 1_1000

• <device_name>: Name defined in Evok configuration.
  • examples: 1, 2, 3, IAQ, xS51, xS18.
  • note: autogen generates device_name as a section number.
• <model_name>: Name defined in device_info configuration section.
• examples: L523, S103, S167.
• <number>: Sequence number (is based on the 'count' parameter in the HW definition).
  • examples: 01, 02, 03, 04, 05, 06, 10, 11, 12.
• <1-Wire_address>: 1-Wire device address without dots.
  • examples: 2895DCD509000035 (from 1-Wire address: 28.95DCD5090000.35),
• <register_address>: Modbus register address (is based on the 'count' parameter in the HW definition).
  • examples: 0, 1, 12, 1000, 1100.
