node-red-contrib-operatelogic 1.0.27
Node-RED OperateLogic Node
(read version information below)
This Node-RED project contains a custom Node-RED node called "OperateLogic" used for controlling a device based on logical rules and operation modes (manual or automatic) and commands (start or stop).
Inputs
Mode:
Mode can be set if:
msg.mode = "manual"or"auto"
Start Commands
Start/stop command in manual mode:
msg.manual = true/false(boolean)
Start/stop command in auto mode:
msg.auto = true/false(boolean)
Start/stop commands will not be accepted from opposite modes. For example:
- In manual mode, a start/stop command from
msg.autowill not be accepted. - In auto mode, a start/stop command from
msg.manualwill not be accepted.
Settings
Rules
Rules can be added/removed. In these rules, you can check flow or global variables against string, number, boolean, flow, or globals with operators:
==: equal!=: not equal>: greater<: lessincl: includes
For every rule, you can type your text of the logic in the textfield. The text can be visualised on the dashboard (see screenshot from dashboard below)
For every rule you can choose in which mode it has to be checked (manual or auto).
When a start command is issued, all specified rules will be checked according to the chosen mode. If all rules are true, the output (output 1) returns the "on" state specified in settings state on.
When a specific rule becomes false, an 'off' command is executed specified in settings state off.
Settings
Restart After Fault:
Checked: The system turns off when a rule is not met. It can be turned on again with a start command when all rules are met.
Unchecked: The system will restart on its own when all rules are met. This only applies in auto mode. In manual mode, you always need to give a new start command.
Remember, the automatic restart function will still work after switching to manual mode and back to auto mode if the device is running during the mode switch. However, if you switch back to auto mode and a rule is missing, the device will obviously stop, but it will not automatically restart when the rule is back to being OK. You will need to issue a new start command to restart the device.”
Check Interval: Time interval (in seconds) for checking the rules.
Save state:
Checked: The current mode and "on"
/"off" state will be saved during restarts of node red. All settings and rules can be adjusted at any time and will immediately take effect.Unchecked: During a restart of Node-RED or changes in the node’s settings, it will not remember its state and the node will initialize to “manual” mode with an “off” state.
Outputs
We have 3 outputs.
Output 1: This output allows you to control your device based on the state specified in the settings (State On/Off).
Output 2: Provides all rule information in the form of an array.
Output 3: Displays the currently selected mode.
Versions:
- V1.0.27: The “initialise mode” setting has been removed and the “Save state” setting has been added. Please refer to the “Save state” setting above for more information.
