Programming in iDM

Introduction

iNELS Design Manager, or IDM3, is for programming iNELS units. This software serves as the platform for configuring device parameters, defining functions, and executing the programming required for iNELS units.

Device parameters, such as sensor range and thresholds, backlights, and operational modes, can be easily adjusted within the IDM3.

The process of programming in IDM3 typically involves defining functions and establishing logical connections between different devices. This allows for the creation of automation scenarios and the implementation of intelligent control strategies.

Starting up

Select the "blue control icon" as shown in Fig 1 > Clicking on the option "New project from default template“ allows you to create a new project from a predefined template.

Select the "Device manager" (Fig 1)> Add "New unit "> Select the central unit > Add "New unit">Select the "Internal-Master/ BUS"> Add "New unit "> Add the devices> Click on the devices to see the "Parameters".

Parameters:

Parameters in the iNELS devices refer to the measurable factors or characteristics that define the behavior or performance of the device. These could include electrical properties, physical dimensions, environmental conditions, and various other specifications depending on the type of device.

These are settings specific to individual devices within your automation system.

The specific parameters of the SA3-022M the iDM as shown in Fig.2, Fig.3 and Fig.4.

Clicking on the SA3-022M (Fig.2), will navigate to firmware, unit address, name, and description, along with other parameters as described below :

It is important to add the device address for proper communication with the unit. The Hexadecimal device address can be find from the device.

Switch limit: The switch limit parameter establishes the highest allowable frequency of relay switching per minute. If the number of switch occurrences surpasses this limit within a minute, the relay will not be triggered.
RE1- RE16 Blocking group of parallel switching: This function is responsible for preventing or halting the simultaneous switching of a relay in parallel with other relays within the designated group. For instance, if you designate RE1, RE2, and RE3 to Blocking group of parallel switching- 1, none of these relays will switch on concurrently. This feature proves useful when connecting these relays to three distinct fans in an air conditioning system. If Fan 1 is activated, Fans 2 and 3 will not switch on in parallel, effectively safeguarding the fans from simultaneous switching.
VALVE1-OPEN, VALVE1-CLOSE Blocking group of parallel switching: "VALVE1-OPEN" and "VALVE1-CLOSE" are parameters used to control the opening and closing of Valve 1, respectively. The "Blocking group of parallel switching" feature allows the actuator to handle multiple parallel switching operations efficiently.

RE1- RE16- Relays are means of controlling various electrical loads, such as lights or other devices. It acts as a switch that can open or close electrical circuits, allowing or interrupting the flow of power to connected devices.

Invert output: "Invert output" refers to the ability to change the state of the output signal. When the output is inverted, a command that would normally turn the output on would instead turn it off, and vice versa.
Use default state: In the context of a switching actuator, the term "default state" pertains to the pre-established or initial condition that the actuator adopts in the absence of communication from the bus or central unit. Enabling this function ensures that the relay automatically assumes its default state, which is set to OFF.
Default output state: Upon choosing the "use default state" option, you will be prompted to specify the default output state. This refers to the pre-established or initial condition that the actuator adopts when there is no communication from the bus stop or central unit. Upon selecting this function, the relay will transition to its default output state, which, in this case, is set to ON.

SHUTTER UP: This parameter controls the operation of moving shutters in the upward direction.
SHUTTER DOWN: Controls the operation of moving shutters in the downward direction.
VALVE 1, 2 OPEN: Initiates the opening of valves 1 and 2 for fluid or gas control applications.

ALERT UNDER VOLTAGE RELAY: Generates an alert in case of under voltage detected by the relay.
OUF-Alert- RE 1-16: This parameter serves as an indicator for alert conditions associated with relay outputs 1 through 16 on the SA3-022M device. The alert is activated when the switching limit surpasses the configured threshold in any of the relay outputs. Upon activation, this alert signals users about a fault in one of the relay outputs, prompting them to investigate and take corrective measures. This is crucial to prevent potential damage to connected loads or the device itself. The designation "RE1-16" specifies that the alert is applicable to each relay output individually, allowing users to pinpoint the specific relay output affected by the alert.
OUF-ALERT-SHUTTER: Generates an alert specific to issues related to shutter operation. The alert is activated when the switching limit surpasses the configured threshold in the shutter outputs. Upon activation, this alert signals users about a fault in one of the outputs, prompting them to investigate and take corrective measures. This is crucial to prevent potential damage to connected loads or the device itself.
OUF-ALERT-VALVE1, 2 -OPEN: The alert is activated when the switching limit surpasses the default threshold (255/min) in the relay outputs. Upon activation, this alert signals users about a fault in one of the valve, prompting them to investigate and take corrective measures. This is crucial to prevent potential damage to connected loads or the device itself.
OUF-ALERT-VALVE1, 2 -CLOSE: The alert is activated when the switching limit surpasses the default threshold (255/min) in the relay outputs. Upon activation, this alert signals users about a fault in one of the valve, prompting them to investigate and take corrective measures. This is crucial to prevent potential damage to connected loads or the device itself.
SW1-SW16: Parameters corresponding to switches 1 through 16, allowing for individual control and monitoring of each switch output. A "switch" could refer to a virtual or physical switch that controls a specific function within the SA3-022M. For example, you might have switches to control lights, heating, or other smart devices in your installation. These switches can be programmed and configured within the iNELS Design Manager to customize the behaviour of your system.

Exports for iNELS Cloud and APP

Setting Up Control and Monitoring for iNELS Cloud and iNELS App

It is possible to control and monitor all the bus units in iNELS cloud and iNELS app. There are two stages to set up this function. Stage one is to do configuration in iDM3 and stage 2 is to do Configuration in iNELS cloud page and iNELS app.

Configuration in iDM3.

1. Unit and Parameter Selection:

Begin by accessing the iDM3 interface on your PC connected to CU. Navigate to the Device Manager section and carefully select the units and parameters you wish to control. This step is essential for determining what gets exported to the iNELS cloud and app.
