[PSUBS-MAILIST] PLC HMI selection

[Steve McQueen via Personal_Submersibles]

Alan, I would also check with ezautomation. The big boys (Rockwell-Allen Bradley/GE/Siemens etc.) are expensive on the software side as well as the hardware. Places like ezautomation provide a lot of the software for free. However it isn’t as full featured as the bigger brands but it will work.

 

Based on your programming class you should find programing  these other brands easy (I find ladder logic is basically the same across vendors). 

 

I would say the cheaper brands (hardware) may not be as “industrial/reliable” as the more expensive hardware.

 

Cliff has some real world PLC/sub data. Carsten has some nice HMIs as well.

Subject: [PSUBS-MAILIST] PLC HMI selection

 

Hi,

am looking at purchasing a PLC & HMI.

Don't know a lot about what I am doing other than I have completed a basic

PLC programming course in RSLogix 500.

I will be having at least 31 analog & 4 digital inputs and 7 digital & 1 analog

output plus HMI connection. So most of the input is just for display on the

HMI & for alarms.

I want the PLC to be as small as possible & have been looking at the Automation

Direct Productivity 1000 stackable Micro PLC

https://www.automationdirect.com/adc/Overview/Catalog/Programmable_Controllers/Productivity_Series_Controllers/Productivity1000_(Stackable_Micro_PLC)

This item has just enough analog inputs.

Also I am looking at a 7-8" HMI screen. Automation Direct have this item I have been

looking at...

https://www.automationdirect.com/adc/Shopping/Catalog/HMI_(Human_Machine_Interface)/C-more_Touch_Panels/C-more_Touch_Panels_EA9_Series/C-more_EA9_Series_Touch_Panels/EA9-T8CL

Is a bit expensive at $999-

I envisage I will be designing the graphics; have done a lot with photoshop in

the past & a tiny bit of annimation, so any program that has similarities to the

photoshop format would probably be helpful, however not too concerned about that.

Has anybody got any suggestions about suitable PLCs & HMIs or any comments 

about what I'm looking at. 

The PLC has a 125V DC input, I couldn't see an IP rating for it. The HMI is IP 25.

Cliff, what size screen do you have & are you feeling it is the correct size?

Thanks,

Alan
