What to do if my RKC INSTRUMENT Controller has no response?

  Meghan ShawAug 4, 2025
  If your RKC INSTRUMENT Controller is not responding, consider the following possibilities: * Ensure the controller power is on. * Verify the communication cable connection method and condition. * Check for and replace any broken communication cables. * Inspect connectors and contacts, replacing wiring if necessary. * Confirm that the communication speed and bit structure settings are correct. * Verify the address numbers. * If a transmission error is found, re-transmit after a timeout or check the communication program. * If none of these steps work, the instrument may have failed and need replacement or repair.

  Error code 2 on your RKC INSTRUMENT Controller indicates one of the following issues: * You may be attempting to write to read-only data; confirm the holding register address. * PID constants or anti-reset windup (ARW) data are set to 0, and self-tuning (ST) function is entered; set the PID constants and anti-reset windup (ARW) data to a number other than 0. * PID constants or anti-reset windup (ARW) data are written during the execution of the self-tuning (ST) function; set the self-tuning (ST) function to 0.
