How to Select PLC for Motion Control

Almost every modern industry uses programmable logic controllers, commonly known as PLCs. These compact electronic devices enable much of the automation that is prevalent in today’s manufacturing processes. PLCs are utilized to get a myriad of purposes in company and business, such as every thing from climate manage systems to complex item assembly and packaging processes.

Buyers unfamiliar with PLCs and their benefits may feel overwhelmed as they begin the process of selecting and purchasing Delta PLC for their business or industry. This guide will offer a short overview from the history and function of PLCs, such as the programming specifications and a few important elements to help keep in thoughts whilst buying for PLCs.

The factors to consider when choosing a PLC:
I/O
Servos
Size of Memory
Communications
Compatibility to HMI
Format
Speed

Format of PLC

You can go away using the format of Little PLC Omron simply because the count of I/O is much less than one hundred and also you don't have servos or analog to compete with; although, from a view of studying point and becoming that Medium Format of PLCs would be the business function horse you'll make use of a Medium Format PLC having a genuine of back-plain.

Speed of PLC

The speed of PLC uses to be a main concern when planning controls but does not truly affect to controls now. Nowadays PLCs are rapid enough for the majority applications with full programs scan times usually less than 4 msec. This is the scan time needed for the PLC to seem at the service and program all the Inputs/Outputs. The Cycle Time is 4 seconds so the majorities PLCs today are glowing when think this requirement of time.

Size matters - Sizing a PLC is crucial towards the achievement of one's project. As well little and also you might max out your I/O on modifications and additions. As well big and also you might blow your spending budget. Be sure you leave space for expansion but do not break the bank.

Count up your:

Discrete input points
Discrete output points
Analog input points
Analog output points

Communications. ALWAYS have a port available on the PLC to communicate with it from your laptop without disconnecting other devices.  With modern PLCs with multiple communications methods, there is no reason for this to happen.

        Will you need remote I/O?  This can reduce installation time and troubleshooting in the long term.
        Will you system utilize an HMI?  How will you communicate with it?
        Will you have a way to remotely monitor it from either the office across the plant or across the country?  It is becoming a standard practice.  Personally I like Ethernet but there are many options.

Brand - I'll be unpopular when I say this, but a PLC is a PLC when it comes to most capabilities.All of the major players such as Allen Bradley, Automation Direct, Mitsubishi,Omron, and Siemens have small, medium, and large scale PLCs. Always consider when brands the end user already is using. Things will always go smoother if the maintenance personel are already familiar with the brand of PLC you choose. Also try to choose a brand that will have good local  support for the end user if you are not in the area.
