  1. As long as I remember, the use of HSC with expansion modules, involves a hardware reset (I37 for reset). Alternatively you can use another register as a buffer. Suggestion: use "greater than", instead of "greater" when you compare values.
  2. Why 9600, 8, n, 2? It isn´t usual. I suggest you to double check COMM INIT and Modbus Config blocks to match VFD parameters (baudrate, data and stop bits, address).
  3. Or simply use three different tags, one for each period, updating (SUM) them in each scan or in a base time. This way, you have instant values for all your periods. Of course, you will need to reset those tags at the right time (daily, weekly, monthly).
  4. Use LINEARIZATION FB. Keep in mind module resolution is 0.1°C, that´s the reason X1 and X2 values are -2000 ... 6000 in the image
  5. Take a look to the module specs. It shows register values when analog input is out of range. https://myzone-kza3sadj.netdna-ssl.com/wp-content/uploads/2015/12/IO-ATC8.pdf
  6. I perform manual tuning when I have temperature process instead of auto tuning. I have better performance. In general, to reduce overshoot, decrease P, but all systems have their own behavior.
  7. I guess you´re using Remote Access software to show your Vision 130 and you believe it is a simulator. However keep in mind that all Unitronics software requires a physical PLC in order to view online data. There is not simulator.
  8. It would be nice to have an option to save VLP file including registers values
  9. I always use terminal resistors at both ends of an RS485 network, even in point-to-point short cables. Also, I use shielded cables ground at a single point. Rarely had problems with this.
  10. For settings, if those are saved as registers, you may use "Export PLC Operands to Text File" under Connection menu. I use to save operands file together with VLP and OS files as a full backup of my applications.
  11. Calibration data keeps on IO-LCx module.
  12. You are using direct contacts instead of coils for VALVE SET / VALVE RESET
  13. I suggest you to manually tune your PID system using any of well known methods, e.g. Ziegler-Nichols
