RD3A instruction supports analog inputs. I found out that it is not a 1:1 copy of Fx3 :( In the Chinese manual, the IVRD function has a completely different register meaning than in the original manual

yes, I understand that IVRD is a manual for inverters, but many people and many manuals use it as a reading from devices.They will try with the RS function, but isn't it for RS 232?

Hi, I have a problem with communication of FX3 (Le3u) with the PT100 extension (pta8d08) via RS485. I use IVRD function. Can you check my project and give me some advice on what might be wrong? I connected to the board using a PC and read the first register.    Best Regards
