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 IOU3-108M in the iDM as shown in Fig.2

Clicking on the IOU3-108M (Fig.2), will navigate to the selected firmware, address, name, and description, along with other parameters as described below :

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.

RE 1-8: Blocking Group 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.

RE1-8 (Relay Outputs 1-8): RE1-8 refers to the relay outputs of the IOU3-108M device. There are eight independent relays with potential-free contacts. These relay outputs are used to control various appliances or loads by switching them on or off. Each relay can be individually addressed and controlled.

Invert Output: Invert output refers to a feature that allows users to invert the logic of the relay output signal. When enabled, the relay output operates in an inverted mode, where a logic HIGH signal (e.g., 1 or ON) results in the relay being deactivated, and a logic LOW signal (e.g., 0 or OFF) activates the relay.
Use Default State: In the context of IOU3 -108M, 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.

OUF-Alert-RE1-8 :

This parameter serves as an indicator for alert conditions associated with relay outputs 1 through 8 on the IOU3 -108Mdevice.

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 "RE1-8" specifies that the alert is applicable to each relay output individually, allowing users to pinpoint the specific relay output affected by the alert.

Synchronization-Alert-RE1-RE2 to RE7-8: Synchronization-Alert-RE1-RE2 to RE7-8 refers to the synchronization alert feature for specific pairs of relay outputs on the IOU3-108M device. This feature ensures that the relay outputs within each pair switch synchronously to maintain proper functionality and prevent issues like phase mismatch.

DIN1-8 (Digital Inputs 1-8): DIN1-8 refers to the digital inputs of the IOU3-108M device. There are eight binary inputs available. These digital inputs are used to connect external devices or sensors with potential-free contacts, such as switches, buttons, alarms, or detectors.

Invert Input: Invert input refers to a feature that allows users to invert the logic of the digital input signal received by the DIN 1-8 inputs. When enabled, a logic HIGH signal (e.g., 1 or ON) at the input would be interpreted as a logic LOW signal (e.g., 0 or OFF), and vice versa.
Split Strictly Long/Short Press: Split strictly long/short press refers to a feature that distinguishes between long and short press events on the digital input of the IOU3-108M device.

Long Press: Holding the digital input signal for a predefined duration (longer than a specified threshold) before releasing it triggers a long press event.

Short Press: Briefly activating the digital input signal without holding it for the predefined duration triggers a short press event.

TIN1-2 (Temperature Inputs 1-2): TIN1-2 refers to the temperature inputs of the IOU3-108M device. There are two temperature input channels available. These temperature inputs support the connection of temperature sensors using a 2-wire connection, such as TC/TZ sensors.

a. Input Types: Input types refer to the supported types of temperature sensors that can be connected to the TIN 1-2 inputs. In this context, the IOU3-108M supports TC/TZ sensors using a 2-wire connection..

b. Average Time: Average time refers to the duration over which the temperature sensor integrates or averages multiple readings to calculate a representative temperature value. This parameter helps to smooth out fluctuations in temperature measurements caused by factors such as sensor noise or rapid temperature changes.

c. Minimum Level: Minimum level refers to the lowest temperature threshold that the IOU3-108M device can measure accurately. It represents the lower limit of the temperature range that can be reliably detected by the connected temperature sensors.

d. Maximum Level: Maximum level refers to the highest temperature threshold that the IOU3-108M device can measure accurately. It represents the upper limit of the temperature range that can be reliably detected by the connected temperature sensors.

OUF-Alert TIN1-2 :

This parameter serves as an indicator for alert conditions associated with temperature inputs 1 and 2 on the IOU3-108M device.

The alert is activated when the switching limit surpasses the configured threshold in any of the inputs. Upon activation, this alert signals users about a fault in one of the temperature inputs, prompting them to investigate and take corrective measures. This is crucial to prevent potential damage to connected loads or the device itself.
