The difference between IEC 101 vs IEC 104 Protocol Communication

Image
The difference between IEC 101 vs IEC 104 Communication Protocol IEC 101 and IEC 104 are protocols used for communication between Supervisory Control and Data Acquisition ( SCADA ) systems and Remote Terminal Units (RTUs). However, they differ in several key aspects. Here is the general key between the two types of protocol: IEC 60870-5-101 Cyclic data transfer: IEC 101 uses a cyclic data transfer mechanism, meaning the master (SCADA) periodically polls the slaves (RTUs) for data. Limited security: IEC 101 has limited security features, making it vulnerable to attacks. Older protocol: IEC 101 is an older protocol, developed in the 1970s. IEC 60870-5-104 Event-driven data transfer: IEC 104 uses an event-driven data transfer mechanism, meaning data is only transferred when there is a change in the status of the remote equipment. Enhanced security: IEC 104 has enhanced security features, including encryption and authentication. Modern protocol: IEC 104 is a more modern protocol, develop...

BAFO USB-RS232 Converter Driver Download All OS

Image
Image Source: Blibli BAFO USB-RS232 Converter Driver Download All OS A USB-RS232 converter is a device that allows you to connect a device or peripheral that uses a RS232 serial interface to a computer that only has USB ports. RS232 is a standard communication protocol used for serial communication between two devices. The converter consists of a USB connector on one end and an RS232 connector on the other end. The USB connector is plugged into a USB port on the computer, while the RS232 connector is connected to the serial port on the device or peripheral. The converter translates the signals between the two interfaces, allowing communication between the device and the computer. USB-RS232 converters are commonly used in industrial settings where older equipment still uses the RS232 interface, but newer computers only have USB ports. They can also be used with legacy devices such as modems, printers, and barcode scanners. When selecting a USB-RS232 converter, it's important to ens...

TL-MR6400 Performance with by U Signal 4G 1 Bar 25% I have been using TL-MR6400 for about 1 year, and this is the signal quality in my village. Using by. U SIM Card, I have a 25% strength signal. Let's say this is a good sign performance of the TL-MR6400, I am still using it while posting this article.  While it is raining, that is the down performance caused by the signal drop. Actually, I have manually set the band frequency for a stable connection.  Update 12/29/2024: Using IM3 Card, I get 25% signal.

TinyWall: A Lightweight and Powerful Firewall for Windows 10

Image
  Introduction In today’s digital landscape, securing your Windows PC from unauthorized network access is crucial. While Windows includes a built-in firewall, many users seek a more efficient and user-friendly alternative.  TinyWall  is a free, lightweight firewall that provides robust protection without unnecessary complexity. This article explores: ✔  What TinyWall is and how it works ✔  Key features and benefits ✔  Installation and configuration guide ✔  Best practices for optimal security 1. What is TinyWall? TinyWall is a  minimalist, no-frills firewall  designed for Windows systems. Unlike traditional firewalls that rely on constant pop-ups and rule-based configurations, TinyWall operates silently, blocking unauthorized connections by default. How TinyWall Works Default-Deny Approach:  Blocks all inbound and outbound connections unless explicitly allowed. Process-Based Filtering:  Controls network access based on applications ...

MODBUS PIN Connection A8000 RS485

Image
MODBUS PIN Connection A8000 The Siemens SICAM A8000 series, specifically the CP-8000, CP-8021, and CP-8022 modules, support Modbus communication. However, they don't have dedicated physical Modbus ports with specific pin connections. Instead, Modbus communication is handled through the device's serial communication ports (RS-485 or RS-232), which are typically used for various communication protocols, including Modbus.      To configure Modbus communication on a SICAM A8000 device, you'll need to follow these general steps: Select the appropriate communication port: Choose the desired serial port (RS-485 or RS-232) based on your specific requirements and the capabilities of your Modbus master device. Configure the serial port parameters: Set the baud rate, parity, stop bits, and flow control settings to match the requirements of your Modbus master device. Enable Modbus communication: Activate Modbus communication on the selected serial port and configure the necess...
