PLC Definition
Just in case, a PLC is a Programmable Logic Controller. This controls your process or machine via a custom program written
most often in ladder logic, but can also be written in structured text or function blocks. Some examples are the Allen Bradley
ControlLogix controllers, as well as their MicroLogix, CompactLogix, and SLC lines. Siemens has the S7-300, S7-1200,
and S7-1500. (You can also use the S7-400 controllers, though they are more often used in their DCS package.)
DCS stands for Distributed Control System. A DCS typically covers an entire process, and is capable of covering an entire plant.
A DCS combines one or more PLCs with an HMI, and allows the integrator to build both together. The project is often developed
with the entire DCS in mind so that all aspects of the system are developed together – instead of developing the PLC first, then
the HMI, followed by alarms, historian, etc.
A DCS takes the PLC/HMI combo and combines several other features into an integrated package:
· Servers and clients. The servers gather tag data from the PLC(s), contain the graphics, and serve both out to clients for operators to use.
· Redundant servers, controllers and/or networks.
· Synchronized alarming and security.
· Historical data logging and trending.
· Batch management.
So, How Do I Choose Which One I Need?
What’s the long term plan for the facility? If you have any intent of tying it all together into a DCS, and the process you’re currently
looking at has a part in it, there’s no time like the present to start your DCS migration.Is the process a stand-alone, supporting or
skid system? If so, a PLC and HMI could be all you need, and if you decide to migrate the rest of the plant to a DCS in the future,
this system could stay a PLC/HMI combo.Do you want to configure, build and commission the system yourself? If so, and you don’t
have formal DCS training, you should put in a PLC and HMI combo. Most DCS packages are so complex that they require formal
training, and without it, you could get into trouble.Do you need a high availability system? What if the controller dies, or your HMI
goes down? You might need redundancy for your controllers and/or OS (operator system) servers. If so, consider a DCS.Are you going
to need a historian, multiple clients, a trend package, batch system, and other DCS features? Granted, there are HMI packages that
provide all these features, but keep in mind that a DCS provides them as well.Is it a large system that you will have an integrator
build and commission? If so, I strongly recommend a DCS. It will save you time and money in the long run.
