Thanks Michael! Never thought of using colors to explain it, Hope your warm and cozy with lights and water.

If your not in a big hurry: https://www.aliexpress.com/item/32735447554.html?spm=a2g0o.productlist.0.0.4bb64fa3utUg4z&algo_pvid=bc0ce765-98e1-4b7b-b2df-a827377dae2d&algo_expid=bc0ce765-98e1-4b7b-b2df-a827377dae2d-34&btsid=0ab6f83115952096750813016ea859&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_   I use a couple of these for digital IO control and analog inputs, out of a Kadet. Haven't looked for a RS232 one yet.

I've looked at several supply houses and none of them have the FC6A version of this card in stock. Hmmm...

I've used the FC4A Analog module, on a FC6A, which they thankfully added a checkbox to help with the remapping of points.  That noted, this is the basis which I am asking the question about the relay card. If they did the analog card, have they also made the other IO modules usable? I'll try it when I get back to the lab that doubles as my garage.  

I'm integrating a small project using an IDEC FC6A-C24. I have a couple fo the IDEC FC4A-R081 relay modules laying around and wondering if the FC4A named module will work on the FC6A? I have one and have tried it but getting a bus error. Not sure if the relay card is good either, as it was rolling around in my travel box.  

Yes, I know this is very old topic.    But I'd like to see some of the actual C+ looking programming, as this is a subject that I think we've limited the power of the Crimson based displays and Data Acquisition modules. (Love the DA30 BTW) I've done some of it but the daily use of this option I think is limited to what we've learned. Red Lion tech hasn't really worked on the Help manual in tis area in quite sometime.

Thanks for the posting. I've noted the move from 3.0 to 3.1 has brought some challenges for sure. I recently had a large project updating some screens to the AB Logix "Enhanced" tag driver. Appears to be much faster to load my screens.  Always learning...

Do you have the source code posted somewhere? GitHub? The Modbus interests me!

I've taken my "widgets" from version 3.0 and exported them into 3.1 with great success.  I'm not thinking its the same issue your having. Red Lion support involved?

If your needing to find one PLC in particular, filter by the MAC address.   If your like me I take a picture then really expand it.  

 

Any success?
