The information in this page is updated in accordance with firmware version TRB16_R_00.07.11.3.


Summary

Inputs and outputs are used for monitoring and controlling a connected device or receiving signals from that device in order to trigger certain events.

This chapter of the user manual provides an overview of the Input/Output section for TRB160 devices.

If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.

Physical characteristics and I/O pin mapping

Electrical characteristics and I/O pin mapping information are presented below.

Power Socket Pinout


  • Power: 9-30 VDC positive (+).
  • Ground: negative/ground (-).
  • I/O: programmable input/output pins; can be set to:
    • open collector (OC) output; max 30 V;
    • digital input; 0-5 V is detected as logical "0"; 8-30 V is detected as logical "1".


Status

The Status page displays the current states of the device's input and output pins:

You can invert an Input pin by clicking the on/off slider under the "Inversion" column or switch the state of an Output pin by clicking the on/off slider under the "State" column.

User can Rename Input/Output interface by clicking on the "Edit" button.



Status from command line


You can also obtain the status of input and output pins via the command line (CLI or SSH). List of possible ubus values in TRB160 devices:

ioman.adc.pwr0
ioman.gpio.dio0
ioman.gpio.dio1

In order to read values, call command ubus call value status :

root@Teltonika-TRB160:~# ubus call ioman.gpio.dio1 status
{
        "value": "0",
        "direction": "in",
        "bi_dir": false,
        "invert_input": false
}
  • dio0 is configurable input / output:
    • "value": "0" means low level state.
    • "value": "1" means high level state.
    • "direction": "in" means input state.
    • "direction": "out" means output state.

To change input settings, use the update command and specify a value:

ubus call ioman.gpio.dio0 update '{"value":"0"}'
ubus call ioman.gpio.dio0 update '{"value":"1"}'
ubus call ioman.gpio.dio0 update '{"direction":"in"}'
ubus call ioman.gpio.dio0 update '{"direction":"out"}'

Note: Changes of configurable pin type from output to input (and reverse) could causes the issues where the specific type was set in configurations. Make sure that configurations do not contradict one another.

Post/Get

Enabling Post/Get provides the possibility to control the state of an output via HTTP POST/GET requests. The figure below is an example of the Auth Settings section of the Post/Get page. It is used to turn Post/Get requests on or off and to set authentication parameters.

Field Value Description
Enable off | on; default: off Turns Post/Get on or off.
Access io_state | io_type | io_value | io_invert; default: io_state, io_type, io_value, io_invert Accessible methods. It is considered that all methods are allowed if this list is empty.
Username string; default: none Username used for authentication in POST/GET queries.
Password string; default: none Password used for authentication in POST/GET queries.
Confirm password string; default: none Repeat the password for confirmation.

Note: password fields are required to enable POST/GET funcionallity.

Post/Get examples


Use a web browser or any other compatible software to send HTTP POST/GET requests to the device.

Setting


Changing states of various I/O is possible using requests. Below is a table containing syntax examples of this usage:

Action POST/GET URL
Turn Output state to high http://192.168.2.1/cgi-bin/io_state?username=user1&password=user1&pin=<dio0/dio1>&state=on
Turn Output state to low after 5 seconds for 3 seconds http://192.168.2.1/cgi-bin/io_state?username=user1&password=user1&pin=<dio0/dio1>&state=on&delay=5&time=3
Check t_time parameter - time is set in miliseconds http://192.168.2.1/cgi-bin/io_state?username=user1&password=user1&pin=<dio0/dio1>&state=on&t_time=msec&time=5000&time=1000
Invert input http://192.168.2.1/cgi-bin/io_invert?username=user1&password=user1&pin=<dio0/dio1>&invert=<0/1> (0 - disable inversion/1 - enable inversion
Change Configurable Input/Output with pin3 to Output http://192.168.2.1/cgi-bin/io_type?username=user1&password=user1&pin=dio0&type=out

Overview:

  • 192.168.2.1 - device default LAN IP address; replace it in accordance with your own configuration.
  • io_state,io_type or io_invert- allows you to change IO state, type or invert cofigurable input.
  • username - login name from Post/Get configuration.
  • password- password from Post/Get configuration.
  • state - turn Output on or off.
  • type - turn Configurable Input/Output to Input or Output.
  • invert - enables inversion on/off (only works with inputs).
  • delay - defines a delay (in seconds) after which the specified action will be performed.
  • time - defines a window of time during which the action will take place. For instance, if you post an on action while specifying time=5, the output will turn on and stay on for 5 seconds before turning off.

Delay and time parameters can be used together. For example, if delay is 10, time is 5, action is on, then 10 seconds after the execution of the command, the output will switch to on (or stay in on state if it was already that way), then after 5 more seconds it will switch to off state. In this case the overall command execution time is 15 seconds.


To use Post/Get via SSH instead of a browser, you may want to use the curl -X command. Simply add the same URL command in between quotes and specify the HTTP method.

Examples:

  • Switch output to High:
curl -X GET "http://192.168.2.1/cgi-bin/io_state?username=user1&password=user1&pin=dout1&state=on"
  • Switch output to Low after delay:
curl -X GET "http://192.168.2.1/cgi-bin/io_state?username=user1&password=user1&pin=dout1&state=off&delay=5"

Reading


Getting the current state of various I/O is possible using requests. Usage is very similar to the examples above:

Examples:

  • Read state of Configurable Input/Output PIN3/PIN4:
curl -X GET "http://192.168.2.1/cgi-bin/io_value?username=user1&password=user1&pin=dio0"
curl -X GET "http://192.168.2.1/cgi-bin/io_value?username=user1&password=user1&pin=dio1"






Posible responses:

  • `io_value` for all pins
* Bad username or password
* Pin does not exist
  • `io_value` for din1, dout1, dio1/2/3
* 0
* 1

Scheduler

The output Scheduler can be used to configure a timetable of when an output should be turned on or off, based on days of the week or month and hours of the day. The General Configuration section is used to turn the Output Scheduler on or off.

The Scheduler is configured in the form of Instances. A Scheduler Instance defines a time interval during which the state of an output associated with the instance will be set to "High". The Output Scheduler Instances list is empty by default. Click the 'Add' button in order to create a new Scheduler Instance:

After this you should be redirected to the configuration page for the newly added Instance which should look similar to this:

Field Value Description
Enable off | on; default: off Turns the Scheduler Instance on or off.
Pin output pin; default: Configurable Input/Output (3) Output pin. The state of the selected output will be set to "High" during the time interval defined in the fields below.
Interval Type Weekdays | Month Days; default: Weekdays Selects the interval type for scheduler to use.
Start Day [Monday..Sunday] | [1..31]; default: Monday | 1 The day that marks the start of the time interval.
Start Time hh:mm ([00..23]:[00..59]); default: 12:00 The hour and minute that mark the start of the time interval.
End Day [Monday..Sunday] | [1..31]; default: Tuesday | 1 The day that marks the end of the time interval.
End Time hh:mm ([00..23]:[00..59]); default: 12:00 The hour and minute that mark the end of the time interval.
Force Last Day off | on; default: off Forces intervals to accept last day of month as a valid option if selected day does not exist during ongoing month. This field becomes visible only when 'Interval Type' is set to Month Days.

A Scheduler Instance will not work unless you turn both the the Scheduler service and the individual instance on:

I/O Juggler

The I/O Juggler is a feature that provides the possibility to create automated rules that perform certain actions based on Input state changes and other conditions. The operating sequence of I/O Juggler can be visualized as such:

When an Input Trigger occurs, the Input check to see if user-specified conditions are also met. If so, it executes a user-specified action.


For example, if we configure the I/O Juggler like this:

  • Trigger - input state rising.
  • Condition - 8:00 AM - 5:00 PM.
  • Action - send email.

The operating sequence would look like this:

  1. A connected device raises the input state.
  2. This TRB160 device checks whether the current time is between 8:00 AM and 5:00 PM.
    • Yes - TRB160 sends an email.
    • No - TRB160 doesn't send an email.

You can specify multiple actions and multiple conditions for any I/O Juggler rule. Selecting conditions is optional. If there are no set or configured I/O Juggler conditions, the operating sequence is as such:

General


The General section is used to Input Trigger rules, which can perform a specified user-configured action when the Input state changes and when certain other user-configured conditions are met (conditions are optional).

Before you can use the I/O Juggler, you must turn it on first (off by default). This can be done by setting the 'Enable' slider to "on"*:

* Input rules for Configurable I/O will work only when the type of the pin is set to "input"

Input


The Input is used to create Input Rules. An Input Rule is triggered by a user-specified input state change. When this trigger occurs, the device executes a specified command if certain specified conditions are met (conditions are optional).

The Input list is empty by default. To create a new Input Rule, look to the Add Input section at the bottom of the page; select an input and click the 'Add' button:

After this you will be redirected to the configuration page for the newly added Rule, which should look similar to this:

Field Value Description
Enabled off | on; default: off Changes current profile to specified one when action triggers.
Trigger interval integer [0..99999999]; default: 1 The shortest amount of time (in seconds) between two triggers. If the input is triggered more than once in a time period shorter than the value specified in this field, the device will react to the first trigger.
Trigger Rising | Falling | Both; default: Rising Input state change that will trigger this rule.
Add actions i/o juggler action(s); default: none Actions that will be executed by this rule when the specified trigger and conditions (optional) occur.
Add conditions i/o juggler conditions; default: none Conditions that have to be met for the rule to take action. Conditions are optional.

Actions


The Actions section is used to manage and create new Actions that can be executed by the I/O Juggler Rules. The figure below is an example of the Actions section, which is empty by default.

To create a new Action, look to the Add an Action section at the bottom of the page; enter a custom name, select an action type and click the 'Add' button:

After this you will be redirected to the configuration page for the newly added Action, which should look similar to this (example for action 'Type: Reboot'):

Action configuration depends on the selected action 'Type'. Each Action can have one or multiple user-defined Conditions assigned to it. Actions that have Conditions assigned to them are executed only if the Conditions are met (a trigger occurrence is not enough to set off these actions). Assigning to Actions is optional.

You will find descriptions of each different action Type described on the sections below.

Conditions


The Conditions section is used to manage and created Conditions for I/O Juggler Actions. The figure below is an example of the Conditions section, which is empty by default.

To create a new Condition, look to the Add a Condition section; enter a custom name, select the Type of the Condition and click the 'Add' button.

After this you should be redirected to the configuration page of the newly added Condition. You will find descriptions of each different Condition type described on the sections below.

Condition type: I/O


I/O Condition type tracks the state of a selected input or output pin and considers the Condition as MET if that pin is in a user-specified state.

Field Value Description
I/O inputs/outputs; default: Output(3) Specifies the I/O pin to which this Condition is listening to.
State High | Low; default: High Specifies in what state the pin has to be in in order for the Condition to be met.

Condition type: Boolean group


Boolean Group will evaluate two or more existing conditions based on selected Boolean type. A Boolean Group condition will considered as MET based on the outcome of the evaluation performed along with one of the available Boolean types:

  • AND - all selected conditions evaluate as TRUE.
  • NAND - at least one selected condition evaluates as FALSE.
  • OR - at least one selected condition evaluates as TRUE.
  • NOR - none of the selected conditions evaluate as TRUE.

For example, if we have two time Conditions (hour and minute) and a third Condition of Boolean group: AND, both Conditions 1 & 2 have to be met for Condition 3 to be evaluated as TRUE.

In this case, if at least one condition is no longer met, the Boolean group: AND Condition is evaluated as FALSE.


Below is an example of Condition type: Boolean group configuration.

Field Value Description
Boolean type AND | NAND | OR | NOR; default: AND Type of boolean condition.
Add conditions conditions; default: none Specifies conditions which have to be met for action to occur.

Condition types: Date/Time


Lastly, you can configure Conditions based on date and time. Date/time Conditions can be configured based on:

  • Minute of the hour
  • Hour of the day
  • Day of the Week
  • Day of the Month
  • Day of the Year

Each type can be configured in two distinct ways:

  1. Specific time - configured as a single value which defines the exact time when the Condition is considered as TRUE. e.g.:
    • Hour: 8
    • Day of Month: 1
  2. Time interval - configured with a start and an end value which define a window of time during which the Condition is considered as TRUE. e.g.:
    • Hours: 8-12
    • Days of Month: 1-12

Impulse Counter

Impulse Counter service can register chages in the `Configurable Input/Output` state of a Power socket when a value is transitioned from low to high, from high to low, or both.

Configuration


The configuration page is used to enable impulse counter and select GPIO pins for input configuration.

Impulse counter configuration

Enabled off | on; default: off Enable impulse counter.
Count store duration Hour | Day | Week | Month; default: Day Define for how long the impulse counts are retained, in seconds, before being reset.
Reset counts -(interactive buttom) Reset collected impulse counts.

Input configuration


A Input configuration defines which `Configurable Inputs/Outputs` will be used for impulse counting. Input configuration list is empty by default. Click the 'Add' button in order to create a new Input instance:

You will then be taken to the configuration page for the newly added input:

Field Value Description
Enable off | on; default: on Enable input configuration.
Name string; default: none Name of input configuration.
