Hi
I have a modicon 984 with proworx 32 that is scaling an analog input, and I need to adjust the scaling. I have new analog input values and % readings from a gauge.
the program reuses the intermediate registers in other rungs so it is difficult to make sense of the logic. I am told the PLC is full, so maybe that is why they reused those registers.
see attached word file - anyone who has used this platform can understand how this scaling is working? Even if I can add a rung and put the intermediate values in some other registers so I can test a new scaling before putting it in service would be a step forward.
I know unity and allen bradley quite well but I am hesitant to try and modify this system while it is running without knowing much about it
