[ENG] 5.7. [DKSF 253.6 IU] Examples of Setting the Module «Logic»

At this page, several simplest examples of configuring the module «Logic» are represented.

Configuring a Thermostat

A NetPing device with a connected external temperature sensor allows to implement functions of a thermostat, supporting a specified range of temperatures by turning on/off a device for heating and/or cooling in the automatic mode.

Task: It is necessary to maintain a temperature of 20°C indoors.

Solution: Let us suppose that an electric heater, which warms a certain room, is connected to a controllable socket №1 of a NetPing device. There is an air conditioner in the room, which is managed by an external IR management module IRC-TR v2. For automation of controlling a heater and an air conditioner to maintain a necessary temperature, there is a need to go to the page «LOGIC» of a device web interface:

There is a need to check checkboxes for first four rules and configure the next settings:

These rules mean that if a temperature in a thermostat 1 (TSTAT1) will exceed a specified one (i.e. above 20°C), an electric heater will be turned off automatically (RELAY 1) and an air conditioner will be turned on the same automatically (IR 1) (rules №1 and №3). To avoid frequent turning on/turning off a heater and an air conditioner, there is a switching hysteresis in a thermostat, which will be described below. If a temperature will fall below a specified value, an air conditioner will be turned off (IR 2) and a heater will be turned on (RELAY 1) (rules №2 and №4).

After setting up the rules, there is a need to click the button «Apply changes».

The next step is a configuration of the module «THERMO(HYDRO)STAT», on the basis of which previously configured rules will work:

A temperature sensor №3 is used to measure a temperature indoors. In the module «THERMO(HYDRO)STAT» there is a need to configure TSTAT1 by choosing a sensor №3 from a drop-down list. Then specify a threshold of 20°C and a switching hysteresis of 2°C.

A hysteresis sets a «corridor» around a specified temperature, within which a thermostat does not respond to temperature fluctuations. This function allows to avoid frequent random switching of a heater (a cooler) caused by natural spontaneous fluctuations of a temperature measured by a temperature sensor.

 If a current status of a thermostat is «above», then a threshold for switching a status is a specified temperature minus a hysteresis value. And vice versa, if a current status is «below», then a threshold for switching is a specified temperature plus a hysteresis value. As soon as a temperature falls or rises and reaches a threshold value including hysteresis thus leaving the limits of «corridor», a status of a thermostat is changed to the opposite one.

After configuring a thermostat, there is a need to click the button «Apply changes».

Recording, saving and replaying IR commands to control an air conditioner is indicated in the corresponding section of a user guide (works for devices supporting an IR control module IRC-TR v2).

Except indicating a relay as an «output» of a rule, there is a need to indicate that this relay will be used together with a logic module. To do this, there is a need to go to the page «220V MANAGEMENT» of a device web interface and choose a management mode «Logic»:

After changing a management mode, there is a need to click the button «Apply changes».

The last step of configuration is starting logic on a corresponding page of a web interface by clicking the button «Start»:

Example of Warning Alarm When a Shock Sensor Triggered

A NetPing device, to which shock sensor PI-90D and siren alarm АС-10 are connected, can perform security functions for remote objects and closets with equipment.

Task: Organising a warning alarm for a remote control of a security guard when breaking a wiring closet with equipment.

Solution: Let us suppose that shock sensor PI-90D, which is installed into a closet with equipment, is connected to the IO line №2 of a NetPing device, while siren alarm АС-10, which is displayed at a remote control of a security guard, is connected to the Relay 1. To configure NetPing for security measures, there is a need to set the next rules in the module «Logic»:

These rules mean when the shock sensor PI-90D  (IO 2) triggers, then a warning alarm АС-10 (RELAY 1) will be activated (rule №1) until a level of an IO line №2 has got a value «logic 1» (rule №2).

After setting up rules, there is a need to click the button «Apply changes».

The next step is a necessity to configure an operation mode of an IO line at the page «INPUT-OUTPUT» of a device web interface. An IO line must work in the mode «input»:

Besides indicating a relay as an «output» for a rule, there is a need to specify that this relay will be used together with a logic module. To do this, there is a need to go to the page «220V MANAGEMENT» of a device web interface and choose a relay management mode «Logic»:

After choosing a source of control for a relay, there is a need to click the button «Apply changes».

The last step of configuration is starting logic at the corresponding page of a web interface by clicking the button «Start»:
