[ENG] 12.2. [DKSF 54.3 IU] How to Use the Module «Logic»?
Rules allow setting a flexible logic scheme of controlling the features of a device depending on variable external conditions. A logic module implements up to 16 rules. All rules are equal in rights and operate in parallel! A rule consists of Input (2), Condition (3), Output (4) and Action (5). If a status of an input object is changed and now corresponds to Condition (3), a rule operates, and Action (5) is performed over an input object.
Checkbox of enabling a rule (1)
A line of a rule is enabled by checking a checkbox «Enable» (1) on the left of a line, and elements of a rule are selected from drop-down lists, from the left to the right. Inactive rules are displayed in gray.
Input (2) and Condition (3)
Input (2) is an information source for a rule operation
Condition (3), at which a rule is applied and a command is issued that changes a status of an output. An available set of conditions is changed depending on a selected type of a task. Rules trigger at the moment when a condition is fulfilled. Conditions (3) represent a sense of an input status.
Summary table of input objects and conditions:
Rule input | Conditions | Explanations |
|---|---|---|
Input 1..8 Discrete inputs 1..4 are built-in, 5..8 are external on a 1-Wire bus. | = logic 0 | Current logic level of an input. |
| = logic 1 | ||
Humidity sensors 1..4 Sensors of a relative humidity on a 1-Wire bus. | t above | Temperature below/above a threshold and a threshold is set here in conditions in degrees of Celsius, it is possible to use a decimal point and a можно negative value. |
| t below | ||
| rel.hum.above | Relative humidity below/above a threshold, a threshold is set here, a value from 0% to 100%. | |
| rel.hum.below | ||
| failed | A sensor does not respond during polling. | |
Smoke 1..4 Smoke sensors through digital adapters on a 1-Wire bus. It is used as an input rule. | in a normal state | No smake. |
| alert | Smoke. | |
| powered off | A power supply of a current loop is off, a sensor (IP 212) is de-energized. | |
| failed | A sensor does not respond during polling. | |
Pinger 1..2 Pingers configured on the page «LOGIC» of a web interface. | silent | There is a response from a specified IP address /FQDN. |
| responds | ||
Power A current power supply source of a device. | battery | |
| 220V grid | ||
Relay 1..4 Relay 100V..240V. It is used as a rule input. | = off | Current physical state of a relay. |
| = on | ||
Start Reset Initialization signal when logic starts, restarts or reset. It is used for setting logic output in a specified initial status. | finished | 5 seconds after the start of the logic. |
started | right after logic starts. | |
Timer/Counter 1..4 Universal programmed objects for organizing consequences, cycles, pulse counters, measuring duration, frequency, etc. It is used as an input rule. | reached | Comparing with a threshold that is set here in a condition, possibly with a decimal point. The value of Timer/Counter – or a number controlled by commands «add1» and «remove1», or a time interval from a command «start from 0» in seconds with a resolution of 0.1 seconds. |
Thermo 1..8 Temperature sensors on a 1-Wire bus. | below | Temperature below/above a threshold, a threshold is set here in conditions in degrees of Celsius, possibly with a decimal point and/or negative value. |
| above | ||
| failed | The sensor does not respond during polling. |
Output (4) and Action (5)
Output (4) is usually controlled by a rule. Action (5) is executed when a rule triggers.
Summary table of output objects and actions:
Rule output | Actions | Explanations |
|---|---|---|
Smoke 1..4 Smoke sensors through digital adapters on a 1-Wire bus. It is used as a rule output | power on | Controlling a power of a current loop. |
| power off | ||
| switch power | ||
| reset | Short-term powering off a loop to deactivate alert. | |
Relay 1..4 Relay 100V..240V. It is used as a rule output. | power off | Relay control. |
| power on | ||
| switch | ||
Signal 1..4 Sending a user customizable notification using SMS, HTTP GET (webhook). | deactivate | For a customizable notification, it is possible to set an activating event «Signal N» on the page «NOTIFICATION» of a web interface, and thus link it to the triggering of a logic rule. |
Timer/Counter 1..4 Universal programmed objects for organizing delays, sequences, cycles, pulse count, measuring duration, frequency, etc. It is used as a rule output. | start from 0 | Zero the value and start timer (counting seconds). |
| zero | Zero the value and stop a timer (counting seconds). | |
| add 1 | Increment/decrement of a counter. | |
| remove 1 | ||
SNMP Setter 1..2 Command SNMP SET for a remote object configured on the page «LOGIC» of a web interface. | power off | Sending a programmed SNMP SET command. The destination address, MIB variable, values for «On» and «Off» are set in the settings of the module «SNMP Setter». |
| power on |
Rule Priority (6)
If two or more rules form conflicting commands at the same time over the same output object (4), a rule with the smallest number will be executed. Rules can be moved up and down using corresponding buttons «Move Up» and «Move Down» (6) at the end of a line.
Important. In the updated module «Logic» (starting from the firmware version DKSF 54.3.1), priorities of rules («While» rule more important than «If» rule) do not work. Also, there is no need to connect a relay to the logic module on the page «RELAYS». All sources of a relay control are made active simultaneously and they are equal in rights! The updated logic module without priorities is easy to determine by the absence of the rule type selection «While»/«If» on the left of a line with a rule.
The checkbox «Enable Logic» (7) and reset (reboot) of the logic (8)
On the top of the page «LOGIC» of a web interface, there is a checkbox (7) that enables the operation of the logic («Enable Logic») and the button «Reset» (8) for the forced reset (logic reboot). The logic is reset when the operation stops, starts, and restarts (in the moment of clicking the top button «Apply changes» (9)), as well as when clicking the button «Reset» (8). Reset activates rules with the input «Start reset» that should be used when returning the objects of a device (Relay, Timer/Counter, etc.) to a preset initial state.
The button «Apply changes» of a rule block (10)
After setting all necessary parameters, the button «Apply changes» (10) saves a configuration.
Examples of Configuration
The examples of using the updated module «Logic» can be learned from the section «[ENG] [Draft]12.5. [DKSF 54.3 IU] Configuration Examples for the Module «Logic».
