This document provides comprehensive instructions for configuring Inhemeter 4G meters, including meter settings configuration using SmartTool desktop application and PNPScada system integration.

Begin by importing the device model into the SmartTool desktop application:

1. Launch the SmartTool desktop application

2. Import the device model: DM_GPRS_INHE-250418, access it on?https://wiki.pnpscada.com/wiki/DM_GPRS_INHE-250418.zip

3. Verify successful import before proceeding to configuration

Select the appropriate communication model based on your connection type:

- For RS-485 connections: Select 485(local)

- For optical connections: Select 485(local)

Configure the meter to communicate with your Head-End System (HES):

1. Access the communication settings interface

2. Enter the HES IP address

3. Specify the designated port number

4. Save and verify the configuration

Before proceeding with PNPScada configuration, ensure the following requirements are met:

- A 4G modem is installed on the meter

- An active SIM card with data connectivity is inserted

- Network connectivity has been verified

The following components are required and should already exist in PNPScada:

- Meter Type: Inhemeter DDZ1513 1 phase DLMS (circa 2019)

- Modem Type: Inhemeter internal 3G/GPRS modem - Client Mode (circa 2019)

1. Navigate to the modem creation interface in PNPScada

2. Select the modem type: Inhemeter internal 3G/GPRS modem - Client Mode (circa 2019)

3. Enter your user-defined name and meter serial number

4. Save the modem configuration

5. Verify that the modem has been successfully added to the system

Result: Upon successful completion, the modem will be registered in the PNPScada system.

1. Access the meter addition interface in PNPScada

2. Select the meter type: Inhemeter DDZ1513 1 phase DLMS (circa 2019)

3. Associate the previously configured modem with the meter

4. Fill in your user defined name and meter serial number

5. Save the meter configuration

Result: Upon successful completion, the meter will appear on the overview page with its associated modem.

After completing the configuration steps:

1. Navigate to the overview page

2. Verify that the newly configured meter appears in the meter list

3. Check that all configured parameters are correctly displayed

To verify successful configuration and begin collecting data:

1. Open the Communication Monitor tool

2. Initiate a test reading session

3. Monitor the communication status and data retrieval

4. Verify that meter data is being successfully received

Upon successful configuration, the system should display:

- Active communication status

- Real-time meter readings

- Successful data collection indicators

- No communication errors in the monitor log

If communication issues occur:

- Verify that the SIM card has active data connectivity

- Confirm that the HES IP address and port are correctly configured

- Check that the 4G modem is properly installed and powered

- Review the Communication Monitor logs for specific error messages

- Ensure that firewall settings permit communication on the designated port

Prepaid and Postpaid Mode Switching Guide 

This guide explains how to switch meters between prepaid and postpaid operating modes using the SmartTool desktop application. 

- Open the SmartTool desktop application

- From the sidebar menu, click on prepaid

- Select Account from the submenu

Configure the following parameters in the Account tab

- Set appropriate account values for postpaid operation as shown the images below.

- After you have modified the values click on Write button, the system will write the postpaid configuration to the meter 

- Wait for the write operation to complete successfully.

- Navigate to the meter status or mode verification screen

- Confirm that the meter displays Postpayment mode as active

Before switching to prepaid mode, verify the current account settings:

- SGC (Supply Group Code):333333

- KRIN(Key Revision Number):1

- TI (Tariff Index):1

This values can be found under the Account tab in the prepaid section.

- Open the Prepaid -> Account tab

- Verify or modify the SGC,KRIN, and TI values as needed

- Ensure all prepaid-specific parameters are correctly set

- Click the write button to write settings to the meter

- Monitor the write process until completion

- Confirm no error occurred during the write operation

- Navigate to the mode verification screen

- Confirm the meter now displays Prepaid Mode as active

Token can be loaded to prepaid meters using two methods:

1. Navigate to the Token loading section in SmartTool

2. Enter or import the 20-digit STS token

3. Click on the Write button 

4. Wait for confirmation that the token was successfully(on the Result column successful status will be ?Meter confirmed? or else you will get an error with status ?-6034? id there is a failure).

5. Verify the credit has been added to the meter 

1. Use the meter?s kaypad or CIU (Customer Interface Unit)

2. Enter the 20-digit token number

3. Press enter or the confirmation button

4. Wait for the meter to accept and process the token

5. Check the meter display for confirmation

- Always verify the meter after switching to ensure proper operation

- Keep a record of SGC,KRIN, and TI values for token generation

- Ensure communication with the meter is stable before writing configurations

- In postpaid mode, token loading functionality is disabled

Issue: Configuration write fails

- Check communication settings (COM port, baud rate)

- Verify meter is powered and responsive

- Ensure you have proper access rights

Issue: Token loading fails in prepaid mode

- Verify the meter is actually in prepaid mode

- Check that the token matches the meter?s SGC,KRIN, and TI

- Ensure the token hasn?t been used previously

Issue: Mode verification shows unexpected results

- Refresh the meter data by reading current configuration

- Check event logs for any mode change failures

- Verify the write operation completed without errors
