IN'O sensor

Presentation

---

The IN'O sensor is a LoRaWAN class A or Class C sensor that manages two different power supplies: one is external and may range from 9V to 24V, the other one is internal on the battery.

The IN'O sensor incorporates 10 digital inputs, and 4 optocoupled outputs. It also includes an external antenna.

The level or a counter can be transferred to the different inputs. It is also possible to get the voltage of the power supply, and to switch ON, OFF or toggle the outputs.

Family code / Release Note

The family code of IN'O sensors is: 50-70-016-(005 and upper) for Class A and 50-70-087-(002 and upper) for Class C

Electronic input/output

Inputs characteristics:

• Internal pull up
• Impedance: > 1MOhm
• Voltage: 0-30Vcc
• Delivered current: 3.5µA
• Maximum frequency signal: 0-100Hz by input

The schematic of the different inputs of the In'O sensor is illustrated below:

Electrical schematic example for input

Output Signal: If there is no true 0Vdc for low state, then it is necessary to put a resistor between 1+/1- to make a pull down. The resistor could be a 100 kOhm.	Dry contact:
NPN Open Collector: compatible with voltage of 3V and a current of 3µA.	NPN Open Collector: Others, need to connect an compatible external power supply with a resistor to limit the current. Below exemple is given with an external 12V power supply.

Electrical schematic example for outputs

On the output, there is a 3V voltage drop. The maximum current is 100mA (or maximum power of 1.5W):

Installation and operation

---

Installation

The housing is intended to be installed inside or outside a building but it must be protected from vertical water spray and direct sunlight.

The product is delivered disassembled. This enables the connection to the screw terminals.

Before connecting your cable strands to the product’s screw terminals, you must insert the cable gland's nut and the seal.

Then connect the wires to the Inputs and Outputs that will be used:

For the connectors, we recommend using several 20-26 AWG single wires. As the connectors pinch the wires plugged inside approximately 4mm from the wire end, strip the wires over a length of approximately 5 to 6mm before plugging them into the connectors.

Once the assembly is complete, the casing can be closed.

The housing is compatible with the following DIN rail adapter:

Radio propagation

In order for the sensor to operate correctly, the number of obstacles should be limited in order to avoid excessive radio wave attenuation. It is also important to place the sensor as high as possible. Also, the antenna needs to be directed upwards.

Autonomy

---

The information in the table below represents how long the battery can last. It is based on the default configuration at ambient temperature (+25°C) within the optimal operating range of the sensor via a LoRaWAN network (one uplink frame), when the spreading factor used is SF12.

The disposable battery has a 3.6Ah capacity, of which 85% is used.

Transmission periodicity	Battery life	Battery life (with 3 Input contacts closed)	Battery life (with 6 Input contacts closed)	Battery life (with 1 Output closed)
1 frame/2 hours	+15 years	12 years	9 years	+1.5 years
1 frame/24 hours	+15 years	+15 years	+15 years	+2 years

A value of 3µA of consumption is added per input connected (contact closed).

When one of the outputs is ON, a consumption of 160µA is added. Due to this consumption, it is highly recommended to use an external power supply.

Video Tutorials - WATTECO

There are three LEDs on the Pulse Sens'O device:

ASSN:      blinking until the association with a network is done. Since release v3.5.2.5530, after 6 hours in association searching the led blinks all 1 minute.

FNC:     blinks for each activated input (in the limit of one blink each 250ms) during first two minutes after startup, after it blinks every minute if an input is activated.during the passed minute. Blinks in configuration mode for each activated input.

CNF:     blinking in configuration mode.

To start up the device, a magnet must be placed next to the sensor for one second (to the left of the cable gland). The red LED blinks quickly during this step. After one second, the red LED stops blinking and the green LED blinks slowly until the association is done.

To switch off the device, repeat the same operation by placing the magnet next to the sensor for 5 seconds. After those 5 seconds, the red LED blinks 5 times slowly.

A reed switch is available under the sticker. A magnet can be used to activate it and perform specific actions on the sensor (switch off, switch on, reassociation…). When the reed switch is activated, the red LED blinks quickly.

• Configuration

Configuration mode
Way to trigger it	One passage of the magnet near the reed switch or specific ZCL command
Way to stop it	Another passage of the magnet or specific ZCL command
Effects on the sensor	The CONF led (red) blinks (3 sec. OFF, 3 sec. ON) and the sensor sends an uplink frame every minute.
Duration	The configuration mode lasts 10 minutes

• A reassociation procedure can be requested if no downlink frame is received by the sensor during a given periodicity (4 days by default) or if a given number (100 by default) is reached or in case of failure (no acknowledgement received) by sending an applicative frame to the sensor or via the sensor’s IHM.

The sensor keeps the AppEUi and DevAddr configured, Confirmed/Unconfirmed configuration and all applicative configurations. However, LoRaWAN configurations (channel, data rate …) are lost.

ReAssociation Mode
Way to trigger it	Three passages of the magnet near the reed switch or ZCL command from LoRaWAN cluster.
Effects on the sensor	The ASSN led (green) blinks as the “no commissioned sensor” LED is lit.

• A factory reset is available on Watteco’s sensors. It deletes all the applicative settings saved in the flash memory (i.e. configured batches and reports will be deleted).

The sensor keeps the AppEUi and DevAddr configured. However, LoRaWAN configurations (channel, data rate…) and applicative configurations are lost.

Factory reset
Way to trigger it	Two quick passages and a long passage of the magnet near the reed switch
Effects on the sensor	The CONF LED (red) and ASSN LED (green) blink at the same time briefly. All the applicative settings (for batches and reports) are deleted. The blinking is illustrated below this table.

The IN’O device implements “ON/OFF” and “Binary Input” clusters, associated to their Outputs and Inputs. The corresponding clusters between the connectors and the EndPoint are shown below:

Connector	End Point	Cluster	Fctrl
Input 1+/1-	0	Binary Input	0x11
Input 2+/2-	1	Binary Input	0x31
Input 3+/3-	2	Binary Input	0x51
Input 4+/4-	3	Binary Input	0x71
Input 5+/5-	4	Binary Input	0x91
Input 6+/6-	5	Binary Input	0xB1
Input 7+/7-	6	Binary Input	0xD1
Input 8+/8-	7	Binary Input	0xF1
Input 9+/9-	8	Binary Input	0x13
Input 10+/10-	9	Binary Input	0x33
Output 1+/1-	0	ON/OFF	0x11
Output 2+/2-	1	ON/OFF	0x31
Output 3+/3-	2	ON/OFF	0x51
Output 4+/4-	3	ON/OFF	0x71

IN’O incorporates the following clusters:

cluster	cluster name	managed attributes
0x0000	Basic	All
0x0050	Configuration	All
0x0006	ON/OFF	All
0x000F	Binary Input	All
0x8004	LoRaWAN	All
0x8005	Multi Binary Inputs	All

Default configuration

A default configuration is set:

• The device reports each day the counter value associated to input 1+/1- (EndPoint 0 / Cluster Binary Input / Attribute Count).
• The device reports the state of input 2+/2- at each variation with a hysteresis of 2 hours (Endpoint 1 / Cluster Binary Input /Attribute Present Value).

Every change made to the default configuration must comply with the legal duty cycle (for example, the most restrictive in the EU is 0.1%, which corresponds to approximately 1 frame per hour with SF12)

Batch report

Configuration

• Configure a batch report on connector input 6+/6- and connector input 5+/5-:

Timestamp and record the input 6+/6- every 100 pulses, and timestamp and record the level of input 5+/5-. A report has to be sent at least every 10 minutes:

→A counter on Input 6+/6- is the End Point 5, Cluster “Binary Input” is 0x000F, and Attribute “Count” is 0x0402.

A level on Input 5+/5- is End Point 4, Cluster “Binary Input” is 0x000F, and Attribute “Present Value” is 0x0055.

There are two different measurements to be recorded in the batch, so the tag size has to be 1. Label 0 can be used for counter and Label 1 for level.

For counter, the delta is 100 and resolution 1. For level, the delta is 1 and resolution 1. The maximum has to be configured for all to 0x800a.

Two frames must be sent to configure this batch.

Label number	Tag label	Tag size
1 or 2	0/1	1
3 or 4	00/01/11/10	2
5 or 6 or 7 or 8	000/001/010/011/100/101/110/111	3
...	...	...

Applicative payload of the present value of input 5+/5-

 

To decode the batch reception, use br_uncompress. Type for binary input attribute counter is U32 (10), type for binary input attribute PresentValue is Boolean (1). Hence the following command must be used:

echo “ 26100040405e7692050000004006 ” | br_uncompress -a 1   0,1,10   1,1 ,1

Result

Known Issues

---

• Batch:
  • Version: V3.5.2.5602.5669
  • Issue: Bad values on the batch, when there is 8 Count from binary input cluster configured in the batch.
  • Workaround: Configure only 7 Count maximum in the batch.
• MultiBinary Input: 
  • Version: V3.5.2.5358.5408, V3.5.2.5466.0
  • Issue: On configuration of the multibinary input cluster, there is no report on variation.
  • Workaround: Set an edge selection to polling, modify the poll period to the period that you want to verify the state of the inputs, and set force notify on binary input cluster for one input.
    • edge selection: 11 05 000F 0400 18 04
    • poll period:        11 05 000F 0403 21 03E8 (1000 ms)
    • force notify:       11 05 000F 0404 10 01
• Binary Input:
  • Version: V3.5.2.5358.5408, V3.5.2.5466.0, V3.5.2.5466.5514
  • Issue: On configuration of the Count attibut of the Binary Input Cluster, it is not possible to configure a delta. A 0xC2 or 0x92 status is sent which describes that there is no slot available.
  • Workaround: Set the delta to 0
• Unconfirmed Mode:
  • Version: V3.5.2.5358.5408, V3.5.2.5466.0, V3.5.2.5466.5514 (devEUI under 70B3D5E75E00BCB8)
