The Industrial Safety Systems and Their Types Industrial automation has minimized the human interaction with the machines but has not completely eliminated it. Industrial safety systems are introduced to protect the human who work in hazardous plants. Some examples of these are oil and gas, chemical and nuclear plants. The industrial safety systems not only protect the humans but also protect the environment and the plant itself from the chemical reactions. These systems do not control any process but in fact come into play when it is not possible to control a process through normal means. They are rather installed as a protective measure and are quickly becoming the need of every working environment. There are various types of safety systems in place and their use depends on the type of industry they are used in. Here is a look at some of them. Process Control Systems (PCS) They are installed for the monitoring of the manufacturing environment and they control the manufact

PROFIBUS

 PROFIBUS PROFIBUS or Process Field Bus was introduced in 1989 and it is sometimes confused with PROFINET. It links plant automation modules with the process control. PROFIBUS uses a multi drop single cable to connect the devices. This method is cost effective especially for larger sites when compared to old methods. Its installation cost is low and it is easy to find faults as well because it is a single cable. Types of PROFIBUS There are two types or versions of PROFIBUS commonly known as 1.    PROFIBUS DP 2.    PROFIBUS PA Here is a brief introduction to both of these types. PROFIBUS DP It runs over two core screened cable that is violet sheathed and its speed varies from 9.6Kbps to 12Mbps. A particular speed can be chosen for a network to give enough time for communication with all the devices present in the network. If systems change slowly then lower communication speed is suitable and if the systems change quickly then effective communication will happen through

Programmable Automation Controller (PAC) Programmable Automation Controller or PAC is an easy to configure PLC style device. It has advanced capabilities and they are already built into its design. It can perform complex functions like loop control, latching, and data acquisition and delivery. They have other advantages too as open architectures are used in their manufacturing and they can connect to almost any device or business system present today. Characteristics of a PAC The term PAC was given by ARC and there were two reasons behind it. To help the users of automated hardware define the applications they need. Give the vendors a term to effectively communicate the characteristics and abilities of their product. ARC also made and explained a few rules or guidelines for a device to be considered as a programmable automation controller. Operate using a single platform : It should be true for single or multiple domains and in drives, motions and process controls. Em
