Delta PLC provides Modbus communication library DMT, which can be used in C# ​​to communicate with Delta PLC over RS485 (Modbus). First of all to use DMT with your application following functions should be imported from kernel32.dll and DMT.dll: using System.Reflection; [DllImport( "kernel32.dll" , CharSet = CharSet.Auto)] static extern IntPtr LoadLibrary ( string dllPath ) ; [DllImport( "kernel32.dll" , CharSet = CharSet.Auto)] static extern bool FreeLibrary ( IntPtr hDll ) ; // Serial Communication [DllImport( "DMT.dll" , CharSet = CharSet.Auto)] static extern int OpenModbusSerial ( int conn_num, int baud_rate, int data_len, char parity, int stop_bits, int modbus_mode ) ; [DllImport( "DMT.dll" , CharSet = CharSet.Auto)] static extern void CloseSerial ( int conn_num ) ; // MODBUS Address Calculation [DllImport( "DMT.dll" , CharSet = CharSet.Auto)] static extern int DevToAddrW ( string seri

In cryptography, Triple DES (3DES or TDES) is a symmetric-key block cipher, which applies the DES cipher algorithm three times to each data block.   https://en.wikipedia.org/w/index.php?title=Triple_DES&oldid=995820064  To use 3DES functionality first off all we need to include “System.Security.Cryptography”. using System.Security.Cryptography;   Then we should create and adjust an object which will do encryption: var tdese = TripleDES.Create(); tdese.Mode = CipherMode.ECB; tdese.Padding = PaddingMode.PKCS7; tdese.Key = ConvertHexStringToByteArray( "AABBCCDDEE11223344556677889900FF" ); var encryptor = tdese.CreateEncryptor();  “ConvertHexStringToByteArray” function to convert hex string to byte array: public static byte [] ConvertHexStringToByteArray ( string hexString ) { if (hexString.Length % 2 != 0 ) { throw new ArgumentException(String.Format(CultureInfo.InvariantCulture, "The binary key cannot have an odd number

A IoT device programmed with Arduino need connect to WiFi at start of device to use internet for data transfer etc. First of all we need to include header file “WiFiClient” to our sketch. # include <WiFiClient.h> With code below we will let user enter WiFi credentials over serial communication. we should add this code to our setup() part of our Arduino sketch. Serial . write ( "Please enter name of your wifi network\n" ); while ( Serial . available () == 0 ){}; String Uid= Serial . readStringUntil ( '\n' ); Serial . write ( "Please enter password of your wifi network\n" ); while ( Serial . available () == 0 ){}; String pass= Serial . readStringUntil ( '\n' ); If you want give user a tool to setup WiFi over serial you can download a free serial communication tool “Vengito Serial Tool”. With this tool user can connect IoT device easily and enter WiFi credentials. Download "Vengito Serial Tool"   For more software tools   Af
