When the temperature in the room drops below the user’s settings, the heating is on. Logical control systems for industrial and commercial machines have been historically implemented through interconnected electric relays and camper timers using ladder logic. Today, most of these systems are built with more specialized programmable microcontrollers or logic controllers . For linear feedback systems, a control loop is organized with sensors, control algorithms and actuators in an attempt to control a variable at an adjustment point . An everyday example is cruise control in a road vehicle; where external influences such as hills would cause speed changes and the driver has the option to change the desired set speed.

While a lock and key are the simplest and cheapest form of access control and remain by far the most popular door security, it is a low-security, low-tech option. Keys can be copied to any main street and locks are vulnerable to collection. Even if you have a lot of people and a lot of closed doors, key management becomes a challenge to say the least. Proptech is one of the biggest security trends in 2022, according to the Security Industry Association’s Megatrends Report 20221. Proptech, or proprietary technology, also known as real estate technology, is technology, software platforms or applications designed for building management, sales and rental. Within the proptech, security technology is a fast-growing segment, as building owners and managers are looking for the best ways to keep tenants, employees and visitors safe.

If an employee leaves your company, your access rights can be removed in seconds. Since a card cannot be easily duplicated, it significantly reduces your overall risk exposure.

Input Log History – An additional advantage of electronic access control is a complete overview of history. Even when an external contractor or visitor needs access, the door can be opened remotely without any effort.

Powerful programming functions allow you to access certain people for specific days and hours with an access control system, as well as for specific doors and door groups in an installation. If a physical key is lost, there is no way to block it or make sure it has not fallen into the wrong hands. The only way to block access to the lost key is to replace it with the original lock: expensive, difficult and unsustainable. The main advantage for industrial control systems in general, including SCADA, is health and safety. Understanding the environment in which employees are controlled or admitted can give you the crucial advantage of keeping them safe.

Because CPIs are not niche, the purchase and maintenance costs of this type of control systems are usually lower for a certain processing speed or update speed. CPIs are also available in a wide variety of sizes and power and can be purchased with options including high or fanless IP reviews . Maintenance and replacement can be considerably easier and there are many options for updating. When processing or computing power becomes a limiting factor, there are generally options for updating processor speed, memory (volatile and non-volatile), port options, number of network interface cards, etc. SIA describes some of the differences between hosted and cloud-based access control systems.

With an access control system, employees can quickly enter the building, making them safer. They don’t have to stay outside looking for a key or a loose ball to put the key in the lock and turn it over. They can scroll a map or use biometric data to quickly enter the building and reduce the risk of an attack. More than ever, companies are asking their employees to access their business IT platform anywhere, anywhere.

This information can be downloaded to a kind of portable memory device with which it can be analyzed. This is not only valuable for your service department and warranty claims, but can also be used in the design phase of a machine.

For example, connect your access control system to an automatic door to allow hands-free access to your building. Modern access control systems make it easy to set specific access times for employees, visitors and even entire groups of people.
