Why am I getting a Response code Error on my Omron Processor?
A 'Response code Error' on your Omron Processor can be caused by an operation mistake. Refer to the CJ/CS Communication Manual for solutions according to an end code. It can also be caused by noise disturbing. In that case, the device should return to normal automatically if the noise is reduced. Press the ESC button to exit the screen. Finally, it can be caused by the CX-Programmer and LCD executing some function at the same time. Press the ESC button to exit the screen and execute this function by either CX-Programmer or LCD, but not both simultaneously.
