FX1n error light

[simonhodge]

When i switch on my FX1n-60MR the error light on the PLC flashes continuosly. I have connected to my Pc and carried out diagnotics which is giving me the error code 6401 which in the help gives me the following: Error code(D8064) 6401 Error messages PARAMETER ERROR LED status(RUN) OFF LED status(PROG.E) Flash PLC ACT STATUS STOP When program is changed(STOP). When program is transferred(STOP). Power is turned ON. Initial STOP to RUN Setting after Power ON. Error contents and causes Program sum check error Managing method STOP the programmable logic controller, select the parameter mode, set the correct data. Can't figure out what to do. One thing which did stop the flashing was to wipe all of the memory on the PLC but as soon as i started writting a new program it started flashing again. Hope someone can help.

I think i've had this a long time ago when using melsec medoc dos. I think there is a relay (probably M8062 or around there) which is still active. monitor those devices and rst.

Sounds like a problem with your parameter settings. Download a set of default parameters and see if it goes away.

It is telling you it's a parameter error - so check them carefully

Where do i get a set of default parameters?

Create a new project in GX Developer or GX IEC Developer. All parameters in a new project are at defaults.

YOU DO ONE THING. CLEAR THE PLC MEMORY ONCE. AND MAKE ONE FRESH SAMPLE PROG. AND THEN CHECK WHETHER THAT ERROR IS GONE OR NOT? AND CAN U TELL ME THE PERIPHERAL DETAILS U USED WITH PLC?
