One point. If you’re using a plc to operate these systems, you need to look at plcs and I/o rated for such use. These generally have built in redundant processors (SIL 3 and higher) and I/o and communications. They also tend to have special memory that can be locked - separate from the general code - so the logic can’t be inadvertently changed. The code for these systems must also be rigorously validated to insure they will perform the tasks they are required to do. These systems tend to come at a high premium (3-4 times the cost of standard plcs.) On a second note, make sure you are familiar with all codes and regulations that govern e-stops and esd systems or you can find yourself in hot water is an incident does occur.
That was super cool thank you for the nice video. I am glad to know they are quicker simply regular PLCs designed to prevent failures by reacting to them faster than a regular PLC. Now I am off to learn more about choosing different Safety Matrices for picking out hypothetical SILs.

ESD and SIS are similar terms and in many cases, they can be considered the same. ESD systems are designed to shut down a process based on certain inputs and events. SIS systems perform many of the same functions, but are designed to a specific reliability level (SIL 1, SIL 2, etc.).
How the ESD communicates and stops the production line of the PLC? Does it uses a Protocol and we hane to programm the PLC to stop the line or it cut's the supply power?
An ESD system switches digital outputs on and off similar to a PLC, but because the logic solver and all I/O is separate from production PLC, it looks only at safety inputs and criteria and takes appropriate action based on that logic. An ESD may close a valve which is separate from the operating process, may de-energize a relay, etc., to drive the process to a safe state. The important aspect is that the ESD operates independently of the operating logic and has its own dedicated sensors, actuators, and I/O.

Yes, these are called hybrid systems, and they are very common in the industry. In these systems, each controller is used specifically for which it is best suited for: PLCs for machine or skid control and DCS for analog and process control. Most of the systems I work on are hybrid-type systems.
Is ESD different from SIS (Safety Instrumented System)? If yes, could you explain in detail? Does ESD and /or SIS have Function modules to calculate certain functions faster?
While some use the terms interchangeably, the two systems are different. ESD systems are typically manually triggered to shut down a system or process. Fire pull stations and E-Stops are typical devices used in ESDs. SIS systems are sensor-monitored, automatic logic systems that will shut down a process without operator assistance when a shutdown condition exists. SIS systems should follow ISA 84/IEC 61508. The purpose of ah ESD and SIS systems is solely safety, not making calculations or executing any kind of process control.
@@realpars At 3:21 of the video, it is said that sensors, controllers and FCE are used as a part of ESD. I find it similar to SIS. This implies that the ESD system is automatic rather than manual. Could you help me understand the difference between ESD and SIS since both are automatic? Also What is usually the SIL of the FCEs used in ESD systems? Thank you in advance.

Thanks a lot for provided this video. I just wanna make it clear, even ESD is in the same safety system with safety PLC (logic solver), is there any different between both of these? again, thank you
A safety PLC is a device that is part of an overall system constructed to protect a process. A Safety PLC can be the basis for an ESD. Safety PLCs can also be the basis for a Safety Instrumented System (SIS). SIS systems follow ISA84/IEC61511, which in simple terms requires a set of sensors completely separate from the basic process control system, a dedicated logic solver, on-line and off-line test protocols, and controls in place to ensure the system has not been altered without a rigid change procedure being followed. So to answer your question, a Safety PLC is a device (logic solver) that forms the basis for an overall safety system, which can be an ESD, or if it meets the requirements of ISA84/IEC6511, it is part of an SIS system.
Hi Shilpa, Thanks for your comment, great to hear that! We do have two blogposts on ESD and FGS. Feel free to check them out over here: realpars.com/fire-alarm-system/ realpars.com/emergency-shutdown-system/ Happy learning!
Yes, those terms are often used interchangeably. Other common names are Safety-Related System (SRS), Instrument-Protective System (IPS), and Emergency Shutdown System (ESS). The important concept is not the name given to the system, but the standards applied to the design and maintenance of the system (ISA 84/IEC 61511/IEC 61508).
A separator is a vessel that allows two or more materials to be separated from one another. A cause and effect analysis for a separator may look one cause of failure, such as over-filling the vessel, having the effect of a spill. It may list other causes of failure, such as over-pressure. What causes and effects that are determined is the result of a formal process that includes operators, engineers, and managers.

PSD and ESD are essentially two terms for the same concept. In the video, we describe an ESD, emergency shutdown system, which monitors the system for conditions that could cause harm to people, the process and equipment or the environment. When a triggering condition is detected, the process is driven to a safe state as quickly as possible. If the system takes these emergency actions, it is best to call it an ESD. PSD's are used to shutdown a process for abnormal conditions as well as for normal process events (end of run).
Yes, it can be, and as presented in this video, it is. SIS systems follow ISA84/IEC61511, which in simple terms requires a set of sensors completely separate from the basic process control system, a dedicated logic solver, on-line and off-line test protocols, and controls in place to insure the system has not been altered without a rigid change procedure being followed.

Hi there, Thanks for your comment! That's a great suggestion for a future video course. I will happily go ahead and pass that on to our course developers. Thanks for sharing and happy learning!
For a Safety Instrumented System, when a fault or safety limit is reached (high level in a tank, for example), the SIS controller can cause an isolation valve, such as the inlet valve to a tank to shutoff to keep the tank from overfilling. The valve used for this shutoff service is typically an on/off valve with a high-reliability solenoid valve. Depending on the SIL level required, it is not uncommon for there to be 2 shutoff valves in series to insure good cutoff. The important concept is that the SIS logic and final control elements are NOT part of the normal process control system, and are there only to provide protection of the process.
