Hi, I am trying to program datatypes for analog function blocs in Ignition Designer and I'm wondering if it's possible to fit datatypes from CX Programmer to the Designer (like it is possible for Rockwell or even NJ Omron) I'm trying to make a discover to the OPC UA Server and I can't find nothing from the live PLC.
Thanks in advance!
Rockwell and Omron PLCs have specific in-protocol APIs that provide the information needed for browsing names and data types. (Undocumented in the NJ case, but reverse engineered for my alternate driver.) Without some form of API, there's nothing Ignition can do.
From what I saw, OMRON NJ or NX series should work fine because they are used with Sysmac Studio software, which is tag base and not register base like CX Programmer...
I told myself that I would take a chance here but I knew it wasn't possible 
Does CX Programmer even put the datatype details in the PLC in any form other than how the logic uses the registers? If it is only held in source form in the tool, there's no hope of auto-discovery, even by reverse engineering.
No I don't think CX Programmer keeps the datatype info in the PLC. I guess the discover would have already worked for me if it was possible. I only wanted to know if there was a tip or something like that..
No, possible doesn't mean automatically implemented. That requires both a way to extract that information at runtime and someone at Omron willing to share that procedure's details.
I found no procedures on this subject on Ignition forums and on Omron as well.. so..
