PEERPSI

My son, 15, in robotics and controls. As such I'm looking for an inexpensive brick PLC with digital and analog that uses either free software of affordable software. Looking to do latter logic and simple analog scaling etc.. I've been working with AB products for decades and I'd like something from that family but the software, unless you like working with a patch over one eye, is too costly. Considering an Arduino but I'd prefer simple ladder logic that is common in industry. Any suggestions?

Okay thanks, seems like we need a firmware upgrade then.

Yes V16, I'm sure I've seen it in other projects that were that version or older.

Different versions but I've been using this software for sometime and I've never come across this.

Can anyone tell me why in one instance I do not get the filter/search input box in controller tags window. See attached image.

Already done.

It defaults back to HEX which is where the problem lies. 1+1=10 4x4=10 are statements people here can understand and deal with. The end user will not be able to understand that if he wants to set range to 800 at the lower end then they need to enter 320.

I'm using D table, DM, values to set timer presets and limit values.

This is really testing my AB minded way of doing things! I've used the > and < instructions and have achieved my goal.

Timer values I wouldn't expect to exceed 500. However, I'm using the DM values to set range which I expect to be 800 to 1000. This value could double depending on how the machine is used.

My goal isn't to load the values on startup it's to allow the end user to set parameters. They will easily understand values entered in decimal, not in HEX.

Yes, in fact I've been through this section. While it does allow you to change the numbering system for display it doesn't retain that change. I'm finding the manual is missing or has incorrect information in a number of places. For instance the analog setup, display screen setup and explanations of instructions. Thanks for the help!

Okay so I have it figured out, 1 bit of information per line, description and the corresponding data take 2 lines. So each screen can only display 2 values and their associated descriptions. That N needs to change to a Y for the screen to display. That is figured out, what I still need to figure out is how to change the DM entry to & decimal instead of # HEX.

This is what I've been going through, see attached pictures. What the manual doesn't talk about is the Y between Setup and No01. That was an N and when I changed it the screen would then appear. I setup four lines for screen 1, manual says 4 are allowed. See the resulting screen. 2 lines are missing.  

So there is a letter on the first line of the setup screen that is by default N, you need to change that to Y. When you escape back to the main default screen you can then cursor through the screens. Problem is I set up 4 lines and only 2 show up? Still also trying to figure out how to change the numbering system in DM screen to decimal so that the operator can understand what the number represents. Not everyone understands 4x4=10!
