PLC for a beginner

[paul larratt]

Hi dave Eaton Easy plc are really easy to use and set up if you want to chat let me know
My field is automation on many types of systems and yours is anneasy one

It's cool that there's so many plc guys. Maybe someone could tell me what they think are the best systems with regard to diagnostics and preventing downtime and why?
I really only know about s7 controllers. I'd like to know how the s7 feature with respect to diagnostics and uptime compare to other brands/technologies.

And how close the languages are to the iec 61131-3 standard for the controllers we're discussing and maybe your preferred language to code in?

Trained in Siemens TIA outside of work.

Use Mitsubishi in work with GX works 2.

Like ladder for troubleshooting and prefer to programme in FB. SFC is ok but prefer FB.

Have done some in ST but find it too nerdy for my liking. More like C language that software developers use.

And does diagnostics redundancy type features in the mitsubishi range? Are they there/good/easy to set up?

We have a lot of HMIs around the site which aid troubleshooting without having to go into the programme sometimes if a skid is alarming as low pressure etc

The online diagnostics are also very good in GX works. There is a simulator to run programmes to debug offline if required.

What's the network/fieldbus?

 

[timbobelfast]

It's standard Ethernet on a dedicated process network. There are some CC link modules connected as well.

I'm not a fan tbh. I only really know profinet. The features seems exponentially better. Do you have redundancy features?

 

[timbobelfast]

No redundancy features such as slave CPUs etc. Reliability has not been an issue.
They are of course all on a UPS power supply system.
