AR1612 cqm1h error

5 posts in this topic

Hi, It is weird that I'm having a fatal error Memory and AR1612 is ON (program mode)even though there's no error in the compilation of the program. Has anyone experienced this before? When I try to put in the run mode, the Fatal error memory will be lost and AR1612 will be turned OFF. and when I try to go back again in program mode, the errors are not there anymore. Is this usually normal?

Thanks for the response!

Is this the same problem as the other posts?

Are you using the Memory Card?

If so, what happens if you remove the Memory Card then cycle power to the PLC?

HI @IO_Rack

yes, it was a new problem. the case is this, I'm able to download the program to the plc(forcing ar1400) after clearing the errors(which is no end instruction). after I download it. there is this error 0x00F1 fatal error and AR1612 is on. when Imgoing to change from program to monitor the ar1612 will be removed and the error will be gone(even changing from monitor to program mode). so I'm pretty sure that the program has been transferred to the memory. but when I power cycle the PLC, the whole program will be gone and the "no end instruction" error will show(considering I have no battery in the PLC). is my procedure correct or I missed something?

Thanks for the reply!

I'm still having trouble understanding what you are trying to do.

Are you trying to write from PLC to Memory Card or Memory Card to PLC?

If you are trying to use the Memory Card in place of the battery, I don't believe that will work. You should get a battery.

You'll need to isolate the problem. Are you downloading via CX Programmer? Does the program work correctly after doing this? (Don't do any Memory Card operations yet)

yes, I'm able to simulate inputs and outputs.

I'm trying to write the program from cx programmer to PLC memory card.

I will test tomorrow if the program will not be lost once the battery is connected.

Thanks for the reply.
