Mitsubishi GX Developer Training PT 1

Where can I find the "R" Registers?

but in my software there is no any option of new project

Hi Robert

Just wondering if you could help me with something

I am trying to change the setpoints on a PT100 that i have in a tank that is controlling a process. I am using GX works software and the temperature control module is an FX3U 4AD. The thing is i am a novice at this and i am not sure how to navigate through the software to find this or how to begin. The PT100 is using 3 setpoints to heat and cool a process 110 degrees c then 100 and then to 80 i just want to change the 110 to 100 but i am not sure how to go about this. Also this PLC is connected to a HMI display. I know this may sound silly but i was expecting to see the values somewhere in the program ie. 110c 100c 80c. but all i see are the M8000 etc and dont know how they relate to the setpoints

I tried to connect to a FX-48MR PLC for more than an hour last night with no success. Can someone tell me where the "FX" option is in PLC TYPE? All I see there is FX0 to FX3 and variations within. There is no straight up "FX" type in my version of GX Developer. Also, I found some evidence that the serial connection might be RS-422. Is this true? I was attempting RS-232.
