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